Subject: x86/xsaves: Add a kernel parameter noxsaves to disable xsaves/xrstors

This patch adds a kernel parameter noxsaves to disable xsaves/xrstors feature.
The kernel will fall back to use xsaveopt and xrstor to save and restor
xstates. By using this parameter, xsave area occupies more memory because
standard form of xsave area in xsaveopt/xrstor occupies more memory than
compacted form of xsave area.

This patch adds a description of the kernel parameter noxsaveopt in doc.
The code to support the parameter noxsaveopt has been in the kernel before.
This patch just adds the description of this parameter in the doc.

Subject: x86/alternative: Add alternative_input_2 to support alternative with
 two features and input

alternative_input_2() replaces old instruction with new instructions with
input based on two features.

In alternative_input_2(oldinstr, newinstr1, feature1, newinstr2, feature2,
		input...),

feature2 has higher priority to replace oldinstr than feature1.

If CPU has feature2, newinstr2 replaces oldinstr and newinstr2 is
executed during run time.

If CPU doesn't have feature2, but it has feature1, newinstr1 replaces oldinstr
and newinstr1 is executed during run time.

If CPU doesn't have feature2 and feature1, oldinstr is executed during run
time.

Subject: x86/xsaves: Change compacted format xsave area header

The XSAVE area header is changed to support both compacted format and
standard format of xsave area.

The XSAVE header of an xsave area comprises the 64 bytes starting at offset
512 from the area base address:

- Bytes 7:0 of the xsave header is a state-component bitmap called
  xstate_bv. It identifies the state components in the xsave area.

- Bytes 15:8 of the xsave header is a state-component bitmap called
  xcomp_bv. It is used as follows:
  - xcomp_bv[63] indicates the format of the extended region of
    the xsave area. If it is clear, the standard format is used.
    If it is set, the compacted format is used.
  - xcomp_bv[62:0] indicate which features (starting at feature 2)
    have space allocated for them in the compacted format.

- Bytes 63:16 of the xsave header are reserved.

Subject: x86/xsaves: Use xsave/xrstor for saving and restoring user space
 context

We use legacy xsave/xrstor to save and restore standard form of xsave area
in user space context. No xsaveopt or xsaves is used here for two reasons.

First, we don't want to use modified optimization which is implemented in
xsaveopt and xsaves because xrstor/xrstors might track a wrong user space
application.

Secondly, we don't use compacted format of xsave area for backward
compatibility because legacy user space applications only don't understand
the compacted format of the xsave area.

Using standard form of the xsave area may allocate more memory for
user context than compacted form, but preserves compatibility with
legacy applications.  Furthermore, even with holes, the relevant cache
lines don't get touched and thus the performance impact is limited.

Subject: x86/xsaves: Add xsaves and xrstors support for booting time

Since boot_cpu_data and cpu capabilities are not enabled yet during early
booting time, alternative can not be used in some functions to access xsave
area. Therefore, we define two new functions xrstor_state_booting() and
xsave_state_booting() to access xsave area just during early booting time.

xrstor_state_booting restores xstate from xsave area during early booting time.
xsave_state_booting saves xstate to xsave area during early booting time.

The two functions are similar to xrstor_state and xsave_state respectively.
But the two functions don't use alternatives because alternatives are not
enabled when they are called in such early booting time.

xrstor_state_booting is called only by functions defined as __init. So it's
defined as __init and will be removed from memory after booting time. There
is no extra memory cost caused by this function during running time.

But because xsave_state_booting can be called by run-time function __save_fpu(),
it's not defined as __init and will stay in memory during running time although
it will not be called anymore during running time. It is not ideal to
have this function stay in memory during running time. But it's a pretty small
function and the memory cost will be small. By doing in this way, we can
avoid to change a lot of code to just remove this small function and save a
bit memory for running time.

Subject: Define kernel API to get address of each state in xsave area

In standard form, each state is saved in the xsave area in fixed offset.
But in compacted form, offset of each saved state only can be calculated during
run time because some xstates may not be enabled and saved.

We define kernel API get_xsave_addr() returns address of a given state saved in a xsave area.

It can be called in kernel to get address of each xstate in xsave area in
either standard format or compacted format.

It's useful when kernel wants to directly access each state in xsave area.

Subject: x86/xsaves: Clean up code in xstate offsets computation in xsave area

This patch cleans up some code in xstate offsets computation in xsave
area:

1. It changes xstate_comp_offsets as an array. This avoids possible NULL pointer
   caused by possible kmalloc() failure during boot time.
2. It changes the global variable xstate_comp_sizes to a local variable because
   it is used only in setup_xstate_comp().
3. It adds missing offsets for FP and SSE in xsave area.

As early printk support is not enabled in the kernel in the

it in the default command line.

I add a new file(cpufreq.c) for the following reasons.
- Registration of platform_device must be unified in SH-Mobile.
- We can't create a node of cpufreq drivers into device tree.
  (Because cpufreq driver is virtual device.)

Subject: ARM: shmobile: Fix device node reference leakage in
 shmobile_init_delay

The of_find_compatible_node() function returns a new reference to the
found node. Instead of just adding of_node_put() calls, simplify the
code by moving the CPU identification logic inside the loop over cpu
nodes, in order to lower complexity from O(n) to O(1) by replacing
of_find_compatible_node() calls with of_device_is_compatible().

The Marvell Berlin BG2Q has 4 TWSI compatible with the Synopsys
DesignWare I2C driver. Add the corresponding nodes.

The pin-muxing setup is also done here, since there cannot be another
muxing setup if I2C{0,1,2,3} are enabled.

Subject: ARM: berlin: add SMP support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds SMP support for Berlin SoCs. Secondary CPUs are reset, then
execute the instruction we put in the reset exception register, setting
the pc at the address contained in the software reset address register,
which is the physical address of the Berlin secondary startup.

This implementation avoid using the pen lock mechanism.

Subject: metag: hugetlbpage: Remove null pointer checks that could never
 happen

There are inconsistent NULL checks in
hugetlb_get_unmapped_area_existing(). The last conditional block in the
loop checks vma, but vma is dereferenced after that.

Due to the checks above however (bearing in mind after_huge is either 0
or 1) vma is guaranteed not to be NULL here, so remove that part of the
check.

Run "make tegra_defconfig; make savedefconf" on v3.16-rc1. This allows
other people to do the same thing to adjust the defconfig file without
their patch bringing in a bunch of irrelevant diffs.

All of the removed options either have been removed from Kconfig, or

All ChromeOS ARM devices that have the standard "CrOS EC" have the
same keyboard mapping.  It's silly to include this same definition
everywhere.  Let's create a "dtsi" fragment that we can include from
many different boards.

This fragment is based on what's currently in tegra124-venice2.dts

Subject: ARM: tegra: Add new PCIe regulator properties

These new properties more accurately reflect the real connections of the
boards and therefore make it easier to match them up with schematics.

Subject: ARM: choose highest resolution delay timer

In case there are several possible delay timers, choose the one with the
highest resolution. This code relies on the fact secondary CPUs have not yet
been brought online when register_current_timer_delay() is called. This is
ensured by implementing calibration_delay_done(),

Subject: ARM: tegra: enable igb, stmpe, i2c chardev, lm95245, pwm leds

The NVIDIA Tegra 3 based Apalis T30 module contains an Intel i210 or
i211 gigabit Ethernet controller, an STMPE811 ADC/touch controller, I2C
buses and PWM LEDs generically accessible from user space and an
LM95245 temperature sensor chip. The later four can also be found on
the Colibri T30 module.

Change location of intc.h so it can be used as #include "intc.h"
instead of the old style #include <mach/intc.h>. Also clean up
some code to get rid of redundant #include <linux/sh_intc.h>.

Subject: ARM: shmobile: Move dma-register.h

Change location of dma-register.h so it can be used as #include
"dma-register.h" instead of the old style #include <mach/dma-register.h>.

From: Magnus Damm <damm+renesas@opensource.se>
Date: Tue, 17 Jun 2014 16:47:29 +0900
Subject: ARM: shmobile: Move most of irqs.h, keep some for pinctl

Move most of irqs.h so it can be used as #include "irqs.h"
instead of the old style #include <mach/irqs.h>.

Legacy code in drivers/pinctrl needs more work to get rid
of the "mach" portion of the include path, so some part
is left in the original location.

From fd44aa5e570d1d8c7d361dcbf94c2b8cd25cfe92 Mon Sep 17 00:00:00 2001
From: Magnus Damm <damm+renesas@opensource.se>
Date: Tue, 17 Jun 2014 16:47:37 +0900
Subject: ARM: shmobile: Move common.h

Change location for common.h so it can be used as #include "common.h"
instead of the old style #include <mach/common.h>.

From 6b8b0cb477b3e77721982effae3415f3c5f58fee Mon Sep 17 00:00:00 2001
From: Magnus Damm <damm+renesas@opensource.se>
Date: Tue, 17 Jun 2014 16:47:45 +0900
Subject: ARM: shmobile: Move pm-rmobile.h, cleanup sh73xx.h

Change location of pm-rmobile.h so it can be used as #include "pm-rmobile.h"
instead of the old style #include <mach/pm-rmobile.h>. Also clean up
the sh7372 and sh73a0 header files to get rid of unused include files.

Subject: ARM: shmobile: Move pm-rcar.h, cleanup r8a7779 case

Change location of pm-rcar.h so it can be used as #include "pm-rcar.h"
instead of the old style #include <mach/pm-rcar.h>. Also clean up
the r8a7779 case to move some unused header file cruft into a C
file.

Subject: ARM: shmobile: Update EMEV2 DTS to include CPU frequency

Add CPU Frequency information to the EMEV2 DTS file. This
will allow us to use the shared C code to on EMEV2 which
reads out the clock frequency from DT and calculates the
delay settings from there.

Subject: ARM: shmobile: Sync Marzen DTS with Marzen reference DTS

Copy the device nodes from Marzen reference into the Marzen device tree
file. This will allow us to use a single DTS file regardless of kernel
configuration. In case of legacy C board code the device nodes may or
may not be used, but in the multiplatform case all the DT device nodes
will be used.

Based on a similar change for the Lager board by Laurent Pinchart.

Subject: ARM: shmobile: rcar-gen2: Update for of_get_flat_dt_prop() update

Commit 9d0c4dfedd96ee54fc075b16d02f82499c8cc3a6 ("of/fdt: update
of_get_flat_dt_prop in prep for libfdt") changed the function prototypes
of of_get_flat_dt_prop():
  - The return type was made const,
  - The last parameter was changed from "unsigned long *" to "int *".
and dt_mem_next_cell():
  - The second parameter was made const.

This causes the following compiler warnings:

arch/arm/mach-shmobile/setup-rcar-gen2.c: In function 'rcar_gen2_scan_mem':
arch/arm/mach-shmobile/setup-rcar-gen2.c:125:15: warning: initialization discards 'const' qualifier from pointer target type [enabled by default]

Update the variable types in rcar_gen2_scan_mem() to fix this.

Subject: ARM: shmobile: rcar-gen2: correct return value of
 shmobile_smp_apmu_suspend_init

The dummy shmobile_smp_apmu_suspend_init() function provided when
CPU_IDLE is not set should not return a value as per the signature
of the function.

This problem appears to have been introduced by
867ba81f728f1daa ("ARM: shmobile: APMU: Add Core-Standby-state for Suspend
to RAM").

Subject: ARM: shmobile: Get rid of redundant EMEV2 mach callbacks

Update the EMEV2 specific SoC callbacks to get rid
of the calls to of_clk_init() and of_platform_populate().
Those calls are by default executed by the functions in
the shared ARM code in case the SoC specific mach
callbacks are NULL.

Subject: ARM: shmobile: r8a7779: Move r8a7779_earlytimer_init to
 clock-r8a7779.c

r8a7779_earlytimer_init() calls r8a7779_clock_init() and
r8a7779_clock_init() is defined in clock-r8a7779.c.

If both CONFIG_COMMON_CLK and CONFIG_ARCH_R8A7779 are enabled,
as will be the case when marzen-reference moves to use
the common clock framework, then setup-r8a7779.c is compiled
but clock-r8a7779.c is not.

As r8a7779_earlytimer_init() is not used by marzen-reference
simply move it to clock-r8a7779.c.

 initialisation into board code

Move the clock initialisation and OF device population from
SoC to board code. This is in keeping with the pattern used by Lager.
And the clock portion is part of decoupling clock initialisation
from SoC code in preparation for moving to the common clock framework.

Subject: ARM: shmobile: r8a7779: Initial multiplatform support

Add Marzen and r8a7779 to CONFIG_SHMOBILE_MULTI. At this
point CCF is not yet supported so you cannot run this code
yet. For CCF support to happen several different components
are needed, and this is one simple portion that moves us
forward. Other patches need to build on top of this one.

Marzen board support exists in 3 flavours:
1) SHMOBILE_MULTI, MACH_MARZEN - board-marzen-reference.c (CCF + DT)
2) SHMOBILE, MACH_MARZEN_REFERENCE - board-marzen-reference.c (DT)
3) SHMOBILE, MACH_MARZEN - board-marzen.c (legacy C code)

When CCF is done then 2) will be removed. When 1) includes same features
as 3) then 3) will be removed.

Based on work for the Koelsch and r8a7791 by Magnus Damm.

Subject: ARM: shmobile: marzen-reference: Instantiate clkdevs for SCIF and TMU

Now that the common clock framework is supported, the clock lookup
entries in clock-r8a7779.c are not registered anymore. Devices must
instead reference their clocks in the device tree. However, SCIF and CMT
devices are still instantiated through platform code, and thus need a
clock lookup entry.

Retrieve the SCIF and CMT clock entries by name and register clkdevs for
the corresponding devices. This will be removed when the SCIF and CMT
devices will be instantiated from the device tree.

Subject: ARM: shmobile: Remove non-multiplatform Marzen reference support

Now that r8a7779 has CCF support remove the legacy Marzen reference
Kconfig bits CONFIG_MACH_MARZEN_REFERENCE for the non-multiplatform
case.

Starting from this commit Marzen board support is always enabled via
CONFIG_MACH_MARZEN, and CONFIG_ARCH_MULTIPLATFORM is used to select
between board-marzen.c and board-marzen-reference.c

The file board-marzen-reference.c can no longer be used together with
the legacy sh-clk clock framework, instead CCF is used.

Subject: ARM: shmobile: Remove Marzen reference DTS

Now that the DTS file r8a7779-marzen.dts can be used with
board-marzen.c and board-marzen-reference.c, proceed with removing
r8a7779-marzen-reference.dts.

Marzen DT reference is now only built for multiplatform
which means that CCF comes with the package. Remove unused legacy
code ifdefs to clean up the code.

Subject: ARM: shmobile: lager: Add VDD MPU regulator for DVFS

The CA15 cluster is capable of voltage scaling. Add the regulator
in the i2c3 node, to allow the generic CPUFreq driver to use it.

Enable the i2c3 pin mux and the device node as well since the
da9210 is connected to that bus.

Note: In R-CAR Gen2, each frequency is using the same voltage,
and DVS control is not used. Therefore, this patch set the
voltage(Vmin/Vmax) to 1000mv.

Add needed information inside CPU0 for the generic cpufreq-cpu0 driver.

- voltage-tolerance = 1%
  It reflects the tolerance for the CPU voltage defined inside the OPP

Subject: ARM: shmobile: koelsch dts: Add VDD MPU regulator for DVFS

The CA15 cluster is capable of voltage scaling. Add the regulator
in the i2c6 node, to allow the generic CPUFreq driver to use it.

Enable the i2c6 pin mux and the device node as well since the
da9210 is connected to that bus.

Note: In R-CAR Gen2, each frequency is using the same voltage,
and DVS control is not used. Therefore, this patch set the
voltage(Vmin/Vmax) to 1000mv.

Subject: ARM: shmobile: Lager memory map update

Update the Lager DTS to make use of the new unified legacy
memory map where the legacy window on Lager and Koelsch
have the same size.

With this change in place the code gets aligned with the
documentation.

After update the Lager board has the following map:
Bank0: 1GiB RAM (Legacy 32-bit: 0x40000000->0x7fffffff)
Bank1: 3GiB RAM (LPAE area: 0x140000000->0x1ffffffff)

Before the update the old map looked like this:
Bank0: 2GiB RAM (Legacy 32-bit: 0x40000000->0xbfffffff)
Bank1: 2GiB RAM (LPAE area: 0x180000000->0x1ffffffff)

Tested with and without LPAE on r8a7790 Lager.

Add a missing inline annotation on a static function, in order to shut
up a bunch of warnings like:

Subject: staging: octeon-ethernet: Move PHY activation to .ndo_open().

This prevents PHY not found types of errors for PHY drivers that are
probed after the Ethernet driver is probed, because the ifconfig UP is
done from userspace after all drivers have been probed.

Also avoid the cvmx-helper-board.c PHY code if a real PHY driver is
present, this allows a bootloader supplied device tree to specify the
PHY information rather than having to modify the code for each
different board.

Subject: m68knommu: Correct page_to_phys when PAGE_OFFSET is non-zero.

The definition of page_to_phys for nommu produces an incorrect value when
PAGE_OFFSET is non-zero.  The nommu version of page_to_pfn works correctly
for non-zero PAGE_OFFSET, so use that instead.

Subject: ARM: dts: mvebu: split SolidRun CuBox into variants

As Mainlining effort for SolidRun CuBox has been carried out on the
Engineering Sample, the board DTS was reflecting this. Actually,
SolidRun CuBox comes in three different variants:
Engineering Sample (ES), production with 1GB RAM (1G),
and production with 2GB RAM (2G).

Therefore, we base current dove-cubox.dts on to the 1G production
variant and add a ES dts to add required quirk for misrouted SDHCI
card detect on top of dove-cubox.dts. For the 2G variant we rely on
the bootloader to setup correct RAM size.

Subject: powerpc/e6500: hw tablewalk: clear TID in kernel indirect entries

Previously TID was being cleared before the tlbsx, but not after.  This
can lead to a multiway hit between a TLB entry with TID=0 (previously
inserted when PID=0) and a TLB entry with TID!=0 that matches PID.
This can theoretically result in undefined behavior, though we probably
get lucky due to the details of the overlap.  It also results in the
inability to use multihit detection to detect other conflicting TLB
entries, as well as poorer TLB utilization due to duplicating kernel
TLB entries.

Rather than try to patch up MAS1 after tlbsx, the entire value is
saved/restored as with MAS2.

I observed a slight improvement in TLB miss performance with this patch
applied.

Commit 82d86de25b9c99db546e17c6f7ebf9a691da557e "TLB lock recursive"
introduced a bug whereby cpu 0 uses the same value for "lock held" as
is used to indicate that the lock is free.  This means that cpu 1 can
acquire the lock whenever it wants, regardless of whether cpu 0 has it
locked, which in turn means we can get duplicate TLB entries.

Add one to the CPU value to ensure we do not use zero as a "lock held"
value.

Subject: powerpc/booke64: wrap tlb lock and search in htw miss with FTR_SMT

Virtualized environments may expose a e6500 dual-threaded core
as two single-threaded e6500 cores. Take advantage of this
and get rid of the tlb lock and the trap-causing tlbsx in
the htw miss handler by guarding with CPU_FTR_SMT, as it's
already being done in the bolted tlb1 miss handler.

As seen in the results below, measurements done with lmbench
random memory access latency test running under Freescale's
Embedded Hypervisor, there is a ~34% improvement.

Memory latencies in nanoseconds - smaller is better
    (WARNING - may not be correct, check graphs)

Subject: ARM: mvebu: remove stub implementation of CPU hotplug on Armada
 375/38x

In preparation to the addition of CPU hotplug support for Armada XP,
and therefore moving the existing stub functions for hotplug support,
this commit removes the reference from the SMP implementation of
Armada 375/38x to the armada_xp_cpu_die() function. Proper CPU hotplug
support for Armada 375 and 38x will be implemented at a later point.

Subject: ARM: mvebu: slightly refactor/rename PMSU idle related functions

The CPU hotplug code will need to call into PMSU functions to enter
and exit from deep idle states. However, the deep idle state is
currently entered by a function called do_armada_370_xp_cpu_suspend()
whose name really suggests it's an internal function, but we need to
export it to other files in mach-mvebu.

Therefore, this commit:

 * Merges the code of do_armada_370_xp_cpu_suspend() into
   armada_370_xp_pmsu_idle_prepare(), into a single function called
   armada_370_xp_pmsu_idle_enter(), which prepares the PMSU for deep
   idle, and then enters the deep idle state. This code will be common
   to both cpuidle and CPU hotplug.

 * For symetry, it renames the armada_370_xp_pmsu_idle_restore()
   function to armada_370_xp_pmsu_idle_exit().

We also remove the 'noinline' qualifier for these functions, which
apparently had no reason to be here.

Subject: ARM: mvebu: implement CPU hotplug support for Armada XP

This commit implements CPU hotplug support for the Marvell Armada XP
platform. The CPU hotplug stub functions from hotplug.c are moved into
platsmp.c, as it doesn't make much sense to have a separate file just
for these two functions.

In addition, this commit:

 * Implements the ->cpu_die() function of SMP operations by calling
   armada_370_xp_pmsu_idle_enter() to enter the deep idle state for
   CPUs going offline.

 * Implements a dummy ->cpu_kill() function, simply needed for the
   kernel to know we have CPU hotplug support.

 * The armada_xp_boot_secondary() function makes sure to wake up the
   CPU if waiting in deep idle state by sending an IPI. This is
   because armada_xp_boot_secondary() is now used in two different
   situations: for the initial boot of secondary CPUs (where CPU reset
   deassert is used to wake up CPUs) and for CPU hotplug (where an IPI
   is used to take CPU out of deep idle).

 * At boot time, we exit from the idle state in the
   ->smp_secondary_init() hook.

This commit has been tested using CPU hotplug through sysfs
(/sys/devices/system/cpu/cpuX/online) and using kexec.

Subject: ARM: mvebu: Don't apply the thermal quirk if the SoC revision is
 unknown

Currently, the thermal quirk is skipped only if the SoC revision is known to be
one that does not need them, but if the SoC revision cannot be obtained, the
quirk is applied assuming it's needed.

However, this quirk must be applied only we are sure the SoC needs it, for it
breaks the thermal support if applied on a SoC that doesn't need it. The reason
for this is that the quirk consists in changing the thermal devicetree
compatible string and register offsets, to workaround a hardware bug in the
early SoC revision.

Such changes are wrong if the SoC is a new revision and doesn't need
the workaround. Therefore, this commit changes the behavior, by
requiring the SoC revision to be known in order to peform a quirk.

Peach-pit and Peach-pi boards are almost similar, hence the DTS file
is also very similar. Sorting nodes in both these files will allow
us to figure out the difference easily.

All the node aliases are sorted in alphabetically increasing order.
There is no functional change with this patch.

Subject: x86, mpparse: Use pr_lvl() helper utilities to replace
 printk(KERN_LVL)

Use pr_lvl() helper utilities to replace printk(KERN_LVL) for readability,
no function changes. Also use pr_cont() to avoid multiple newlines in
one printk().

Subject: x86, mpparse: Simplify arch/x86/include/asm/mpspec.h

Simplify arch/x86/include/asm/mpspec.h by
1) Change max_physical_apicid to static as it's only used in apic.c.
2) Kill declaration of mpc_default_type, it's never defined.
3) Delete default_acpi_madt_oem_check(), it has already been declared
   in apic.h.
4) Make default_acpi_madt_oem_check() depends on CONFIG_X86_LOCAL_APIC
   instead of CONFIG_X86_64 to support i386.
5) Change mp_override_legacy_irq(), mp_config_acpi_legacy_irqs() and
   mp_register_gsi() as static because they are only used in acpi/boot.c.

Subject: x86, acpi, irq: Kill static function irq_to_gsi()

Static function irq_to_gsi() is only called by acpi_isa_irq_to_gsi(),
so kill function irq_to_gsi() and simplify acpi_isa_irq_to_gsi().

Subject: x86, ACPI, irq: Fix possible eror in GSI to IRQ mapping for legacy
 IRQ

A default identity mapping between GSI and IRQ is built for legacy IRQs.
So when overriding the default identity mapping for legacy IRQs,
we should also invalidate isa_irq_to_gsi[gsi] when setting
isa_irq_to_gsi[irq] = gsi.  Otherwise there may be two entries with the
same GSI in the isa_irq_to_gsi array, and acpi_isa_irq_to_gsi() may give
wrong result.

1) Kill unused MAX_HARDIRQS_PER_CPU.
2) Improve function prototype declararions.
3) Simple typo fix, change "gsit" to "gsi".
4) Use macro VECTOR_UNDEFINED instead of hard-coded -1.
5) Kill redundant comments.

Subject: x86, ioapic: Kill static variable nr_irqs_gsi

Static variable nr_irqs_gsi is used to maintain the lowest dynamic
allocatable IRQ number. It may cause trouble when enabling dynamic
IRQ allocation for IOAPIC, so use arch_dynirq_lower_bound() to
avoid directly accessing nr_irqs_gsi and kill nr_irqs_gsi.

Subject: x86, ioapic: Introduce helper utilities to walk ioapics and pins

Introduce helper utilities for_each_ioapic(), for_each_ioapic_reverse(),
for_each_pin() and for_each_ioapic_pin() to walk ioapics and pins.
They will be rewritten e will rewrite later to support IOAPIC hotplug.

Subject: x86: ce4100, irq: Make CE4100 depend on CONFIG_X86_IO_APIC

Intel CE4100 platforms need IOAPIC support becasue some devices are
always connected to the second IOAPIC, so make CONFIG_CE depends on
CONFIG_X86_IO_APIC.

Subject: x86: ce4100, irq: Do not set legacy_pic to null_legacy_pic

Intel CE4100 platforms has i8259 legacy interrupt controllers, so don't
set legacy_pic to null_legacy_pic in late booting stage because we need
legacy_pic to mask i8259 pins when enabling IOAPIC pins for safety.

Subject: x86, irq: Count legacy IRQs by legacy_pic->nr_legacy_irqs instead of
 NR_IRQS_LEGACY

Some platforms, such as Intel MID and mshypv, do not support legacy
interrupt controllers. So count legacy IRQs by legacy_pic->nr_legacy_irqs
instead of hard-coded NR_IRQS_LEGACY.

Subject: x86, ACPI, irq: Consolidate algorithm of mapping (ioapic, pin) to IRQ
 number

Currently ACPI and ioapic both implement algorithms to map (ioapic, pin)
to IRQ number. So consolidate the common part into one place, which is
also preparing for irqdomain support.

It introduces mp_map_gsi_to_irq(), which will be used to allocate IRQ
number IOAPIC pins when irqdomain is enabled.

Also rename gsi_to_irq() to map_gsi_to_irq(), later we will introduce
unmap_gsi_to_irq() when enabling IOAPIC hotplug.

Subject: x86, irq, ACPI: Change __acpi_register_gsi to return IRQ number
 instead of GSI

Currently __acpi_register_gsi is defined to return GSI number and
may be set to acpi_register_gsi_pic(), acpi_register_gsi_ioapic(),
acpi_register_gsi_xen_hvm() and acpi_register_gsi_xen().

Among which, acpi_register_gsi_ioapic() returns GSI number, but
acpi_register_gsi_xen_hvm() and acpi_register_gsi_xen() actually
returns IRQ number instead of GSI. And for acpi_register_gsi_pic(),
GSI number equals to IRQ number.

So change acpi_register_gsi_ioapic() to return IRQ number, it also
simplifies the code.

Subject: x86, irq: Introduce mechanisms to support dynamically allocate IRQ
 for IOAPIC

Currently x86 support identity mapping between GSI(IOAPIC pin) and IRQ
number, so continous IRQs at low end are statically allocated to IOAPICs
at boot time. This design causes trouble to support IOAPIC hotplug.

This patch implements basic mechanism to dynamically allocate IRQ on
demand for IOAPIC pins by using irqdomain framework.

It first adds several fields into struct ioapic to support irqdomain.
Then it implements an algorithm to dynamically allocate IRQ number
for IOAPIC pins on demand.

Currently it supports three types of irqdomain:
1) LEGACY: used to support IOAPIC hosting legacy IRQs and building
   identity mapping for legacy IRQs. A speical case, we dynamically
   allocate IRQ number for IOAPIC pin which has GSI number below
   nr_legacy_irqs() but isn't legacy IRQ. This is for backward
   compatibility and avoid regression.
2) STRICT: build identity mapping between GSI and IRQ nubmer.
3) DYNAMIC: dynamically allocate IRQ number for IOAPIC pin on demand.

Legacy(ISA) IRQs is not managed by irqdomain because there may be
multiple pins sharing the same IRQ number and current irqdomain only
supports 1:1 mapping between pins and IRQ.

Subject: x86, irq: Enhance mp_register_ioapic() to support irqdomain

Enhance function mp_register_ioapic() to support irqdomain.
When registering IOAPIC, caller may provide callbacks and parameters
for creating irqdomain. The IOAPIC core will create irqdomain later
if caller has passed in corresponding parameters.

Subject: x86, ACPI, irq: Provide basic irqdomain support

Enhance ACPI driver to provide basic irqdomain support for IOAPIC.

We will build identity mapping for IOAPICs hosting legacy IRQs,
otherwise dynamically allocate IRQ numbers for IOAPIC pins on demand.

Subject: x86, SFI, irq: Provide basic irqdomain support

Enhance SFI to provide basic support of irqdomain with identity mapping
between GSIs and IRQs.

Some Intel MID platforms assumes identity mapping between GSI and IRQ,
so we can't dynamically allocate IRQ number on demand.

Subject: x86, irq: Introduce two helper functions to support irqdomain map
 operation

Currently there are multiple entries to program IOAPIC pins, such as
io_apic_setup_irq_pin_once(), io_apic_set_pci_routing() and
setup_IO_APIC_irq_extra() etc.

This patch introduces two functions to help consolidate the code to
program IOAPIC pins. Function mp_set_pin_attr() is used to optionally
set trigger, polarity and NUMA node property for an IOAPIC pin.
If mp_set_pin_attr() is not invoked for a pin, the default configuration
from BIOS will be used.

Function mp_irqdomain_map() is an common implementation of irqdomain map()
operation. It figures out attribures for pin and then actually programs
the IOAPIC pin. We hope this will be the only entrance for programming
IOAPIC pin.

And the flow will:
1) caller such as xxx_pci_irq_enable figures out pin attributes.
2) Invoke mp_set_pin_attr() to set attributes for a pin. If the pin has
   already bin programmed,  mp_set_pin_attr() will aslo detects attribute
   confictions.
3) Invoke mp_map_pin_to_irq()
3.1) If IRQ has already been assigned, return irq_find_mapping()
3.2) Else irq_create_mapping()
		->irq_domain_associate()
			->mp_irqdomain_map()
				->io_apic_setup_irq_pin()

So every pin will only programmed once by mp_irqdomain_map(), so we
could kill io_apic_setup_irq_pin_once(), io_apic_set_pci_routing() and
setup_IO_APIC_irq_extra() etc.

Subject: x86, irq, devicetree: Use common irqdomain map interface to program
 IOAPIC pins

Refine devicetree to use common irqdomain map interface to program
IOAPIC pins, so we can unify the callsite to progam IOAPIC pins.

Subject: x86, irq: Clean up unused IOAPIC interface

Now we have converted all x86 platforms to use the common irqdomain map
interface. There's no caller of io_apic_set_pci_routing(),
setup_IO_APIC_irq_extra() and io_apic_setup_irq_pin_once() any more,
so kill them.

Subject: x86, irq: Simplify the way to handle ISA IRQ

On startup, setup_IO_APIC_irqs() will program all IOAPIC pins for ISA
IRQs. Later when mp_map_pin_to_irq() is called, it just returns ISA IRQ
number without programming corresponding IOAPIC pin.

This patch consolidates the way to program IOAPIC pins for both ISA and
non-ISA IRQs into mp_map_pin_to_irq() as below:
1) For ISA IRQs, mp_irqs array is used to map IOAPIC pin to IRQ and
   mp_irqdomain_map() is used to actually program the pin.
2) For non-ISA IRQs, irqdomain is used to map IOAPIC pin to IRQ, and
   mp_irqdomain_map() is also used to actually program the pin.

Subject: x86, irq: Introduce helper functions to release IOAPIC pin

Introduce function mp_unmap_irq() to release IOAPIC IRQ when IRQ is not
used any more, which will typically called by pcibios_disabled_irq.

And function mp_irqdomain_unmap() is a common implementation of
irq_domain_ops.unmap for IOAPIC.

Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Commit 5ea3b1b2f8ad 'cma: add placement specifier for "cma=" kernel parameter'
adds a new 'fixed' parameter to dma_contiguous_reserve_area(). Update
rcar_gen2_reserve() accordingly.

This fixes the following compilation error:

Subject: ARM: sunxi: Add earlyprintk support using R_UART (sun6i/sun8i)

sun6i/sun8i have a UART in the RTC block group, which can be used
as an early console. This is most useful on sun8i as UART0 is muxed
with MMC0, which is not available if we boot from MMC.

Subject: ARM: timer-sp: allow getting timer1 clock from DT to fallback to
 legacy clock

The sp804 clocks may be specified in DT, but the kernel may still be using
legacy clocks. This is handled if a single clock for sp804 is present,
but not when 3 clocks are present.

This prevents Versatile platforms from breaking when the DT has clocks
added.

Subject: dts: versatile: add clock tree

The versatile dts is missing any clock data. Add the clocks.

It is not clear from the documentation where pclk comes from, so for
now it is a dummy clock which is sufficient for things to work.

From: Geert Uytterhoeven <geert+renesas@glider.be>
Date: Fri, 20 Jun 2014 18:53:08 +0200
Subject: ARM: shmobile: Move sh7372.h

Change location of sh7372.h so it can be included as "sh7372.h"
instead of the old style <mach/sh7372.h>

Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>

In machine_check_e500 exception handler is a wrong indication
in case of MCSR_BUS_WBERR - so print "Write" instead of "Read".

Subject: pcmcia: Remove m8xx_pcmcia driver

This driver doesn't build, and apparently has not built since
arch/ppc was removed in 2008 (when mk_int_int_mask was removed
from asm/irq.h, among other build errors).

A few weeks ago I asked whether anyone was actively maintaining
this code, and got no positive response:
http://patchwork.ozlabs.org/patch/352082/

So, let's remove it.

Subject: powerpc/8xx: Remove empty asm/mpc8xx.h

m8xx_pcmcia_ops was the only thing in this file (other than a comment
that describes a usage that doesn't match the file's contents); now
that m8xx_pcmcia_ops is gone, remove the empty file.

Subject: ARM: shmobile: Allow use of boot code for non-SMP case

Allow build of platsmp.c and headsmp.S even though
SMP is disabled in the kernel configuration. With
this in place it is possible to share the reset
vector setup code with power management code that
needs to be built even though SMP is disabled.

Subject: ARM: shmobile: Allow r8a7791 to build non-SMP APMU code

Build the APMU for r8a7791 even though SMP is
disabled in the kernel config. Also initialize
Suspend-to-RAM from pm-r8a7791.c to in the future
cover both UP and SMP use cases of the APMU.

Subject: of: Migrate of_find_node_by_name() users to for_each_node_by_name()

There are a bunch of users open coding the for_each_node_by_name() by
calling of_find_node_by_name() directly instead of using the macro. This
is getting in the way of some cleanups, and the possibility of removing
of_find_node_by_name() entirely. Clean it up so that all the users are
consistent.

Subject: ARM: integrator: get rid of <mach/memory.h>

The Integrator has a custom <mach/memory.h> header defining the
BUS_OFFSET for *_to_bus and bus_to_* operations as offset from
0x80000000.

This switches the Integrator over to using the mechanism
introduced for the Keystone to provide the same offset using
the device tree, deletes <mach/memory.h> and augments the
Integrator device tree to provide the bus offset.

Subject: video: move Versatile CLCD helpers

This moves the Versatile-specific helper code and panel database
down into the drivers/video folder next to the CLCD driver
itself, preserving the config symbol but also moving the header
to platform data.

This is necessary to rid the Integrator of this final <plat/*>
inclusion dependency and get us one less user of the
plat-versatile folder.

Subject: ASoC: fsi: use SNDRV_DMA_TYPE_DEV for sound buffer

Current fsi driver is using SNDRV_DMA_TYPE_CONTINUOUS
for snd_pcm_lib_preallocate_pages_for_all().
But, it came from original dma-sh7760.c,
and no longer needed.
This patch exchange its parameter, and removed
original dma mapping and un-needed
dma_sync_single_xxx() from driver.

Subject: ARM: mvebu: Use system controller to get the soc id when possible

On Armada 38x it is possible to get the SoC Id and the revision
without using the PCI register. Accessing the PCI registers implies
enabling its clock and, because of the initialization issue, not
keeping them enable. So if possible it is better to avoid it.

Armada 370 and Armada XP provides the SoC ID values from the system
controller but not the revision.

Armada 375 provides both but the SoC ID value looks buggy (0x6660
instead of 0x6720).

Subject: ARM: s5p: cut the custom ARCH_NR_GPIOS definition

The number of GPIOs defined for the different S5P platforms using
the tricky #define macros are actually as follows:

S5P64x0: 180 GPIOs
S5PC100: 115 GPIOs
S5PV210: 252 GPIOs

The include file <asm-generic/gpio.h> will automatically bump us
to 256 GPIOs which is a nice default value that happens to encompass
all the S5P platform requirements under its roof.

Cut ARCH_NR_GPIOS and the custom spacing macro for extra GPIOs
that is not used anywhere in the kernel.

and cuts the implicit inclusion of <mach/gpio.h> from <linux/gpio.h>
by removing the use of NEED_MACH_GPIO_H from all S5P variants.

Subject: ARM: kill CONFIG_NEED_MACH_GPIO_H

The long pain of maintaining the legacy <mach/gpio.h> include
ladder is now gone with S5P as the last user being deleted. Cut
this Kconfig option and remove the inclusion directive in
<asm/gpio.h> for good.

Subject: ARM: sun8i: dt: Add Ippo-q8h v5 support

The Ippo-q8h is a tablet circuit board commonly found in cheap Android
tablets with A23 SoCs. There are at least 2 versions of the board, with
different peripherals, such as WiFi chips.

Common features among these tablets include 512 MB DRAM, NAND, MMC, LCD,
capacitive touchscreen, accelerometer, 1 or 2 camera sensors, USB OTG,
microphone and speaker.

v5 of these board designs has a ESP8089 WiFi chip (not supported)
connected to mmc1. This patch adds very basic support.

From e288f1bac490791e7564474b89b7c48ee537b6a7 Mon Sep 17 00:00:00 2001

Subject: ARM: dts: sun4i: Add AXP209 support to various boards

At a node for the axp209, and where necessary the i2c controller to the dts
for various boards. Note the axp209 regulators are omitted as we don't have
any use for them yet, and on some boards were not sure how exactly they are
wired up.

Adding support for just the axp209 without the regulators is still useful, as
it will give us power-button and poweroff support.

Subject: ARM: dts: sun4i: Add new ba10-tvbox board

The ba10 tvbox is an A10 based android tvbox, with 512M RAM, 8G nand flash,
rtl8188ctv usb wifi 1 USB-A receptacle hooked up to an EHCI/OHCI controller,
1 USB-A receptacle hooked up to the OTG and 100Mbit ethernet using a
rtl8201 phy.

The PCB is labelled ba10 hence I've named the board ba10-tvbox. It is used
in noname allwinner A10 tv-boxes.

Subject: ARM: nommu: don't limit TASK_SIZE
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With TASK_SIZE set to the maximal RAM address booting in some XIP
configurations fails (e.g. on efm32 DK3750). The problem is that
strncpy_from_user et al. check for the address not being above TASK_SIZE
(since 8c56cc8be5b3 (ARM: 7449/1: use generic strnlen_user and
strncpy_from_user functions)) and this makes booting fail if the XIP
flash is above the RAM address space.

This change is in line with blackfin, frv and m68k which also use
0xffffffff for TASK_SIZE with !MMU.

Subject: ARM: make user_addr_max more robust
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With CONFIG_MMU=y get_fs() returns current_thread_info()->addr_limit
which is initialized as USER_DS (which in turn is defined to TASK_SIZE)
for userspace processes. At least theoretically
current_thread_info()->addr_limit is changable by set_fs() to a
different limit, so checking for KERNEL_DS is more robust.

With !CONFIG_MMU get_fs returns KERNEL_DS. To see what the old variant
did you'd have to find out that USER_DS == KERNEL_DS which isn't needed
any more with the variant this patch introduces. So it's a bit easier to
understand, too.

Also if the limit was changed this limit should be returned, not
TASK_SIZE.

Subject: irqchip: or1k-pic: Migrate from arch/openrisc/

In addition to consolidating the or1k-pic with other interrupt
controllers, this makes OpenRISC less tied to its on-cpu
interrupt controller.

All or1k-pic specific parts are moved out of irq.c and into
drivers/irqchip/irq-or1k-pic.c

In that transition, the functionality have been divided into
three chip variants.
One that handles level triggered interrupts, one that handles edge
triggered interrupts and one that handles the interrupt

+OpenRISC 1000 Programmable Interrupt Controller
+
+Required properties:
+
+- compatible : should be "opencores,or1k-pic-level" for variants with
+  level triggered interrupt lines, "opencores,or1k-pic-edge" for variants with
+  edge triggered interrupt lines or "opencores,or1200-pic" for machines
+  with the non-spec compliant or1200 type implementation.
+
+  "opencores,or1k-pic" is also provided as an alias to "opencores,or1200-pic",
+  but this is only for backwards compatibility.
+
+- interrupt-controller : Identifies the node as an interrupt controller
+- #interrupt-cells : Specifies the number of cells needed to encode an
+  interrupt source. The value shall be 1.
+
+Example:
+
+intc: interrupt-controller {
+	compatible = "opencores,or1k-pic-level";
+	interrupt-controller;
+	#interrupt-cells = <1>;
+};

Subject: ARM: OMAP: add deprecation message for legacy OMAP DMA API

The legacy OMAP DMA API is now deprecated; all remaining users should
now convert over ASAP to using the DMA engine API instead of the OMAP
private API.

Subject: ARM: simplify generation of compressed vmlinux.lds file

As we are now using the C preprocessor, we do not need to use sed to
edit constants in this file, and then pass the resulting file through
the C preprocessor.  Instead, rely solely on the C preprocessor to
rewrite TEXT_START and BSS_ADDR.

Subject: ARM: 8078/1: get rid of hardcoded assumptions about kernel stack size

Changing kernel stack size on arm is not as simple as it should be:
1) THREAD_SIZE macro doesn't respect PAGE_SIZE and THREAD_SIZE_ORDER
2) stack size is hardcoded in get_thread_info macro

This patch fixes it by calculating THREAD_SIZE and thread_info address
taking into account PAGE_SIZE and THREAD_SIZE_ORDER.

Now changing stack size becomes simply changing THREAD_SIZE_ORDER.

From b675d1ecced015f180d5d43056bed94cda87d80f Mon Sep 17 00:00:00 2001
From: Darren Etheridge <detheridge@ti.com>
Date: Tue, 1 Jul 2014 16:00:20 -0500
Subject: ARM: dts: am335x-evmsk: enable display and lcd panel support

Add the necessary nodes to enable the LCD controller and the
LCD panel that is attached to the Texas Instruments AM335x
EVMSK platform.  Also setup the necessary pin mux within the
DT file to drive the LCD connector and add the correct
pinmux settings for the lcd pins to be configured to when
the SoC goes into sleep state for the minimum power
consumption.

For the sleep mode LCD pin settings, MUX_MODE7 is chosen as
this corresponds to switching the pins into input GPIO's with
an internal pulldown.  Which has been determined to offer the
lowest power solution vs leaving the pins configured in LCD
mode.

Subject: arm: perf: move event map macros to pmu.h

A few PMU-related macros are now looking a little lonely in
asm/perf_event.h now that all other PMU-specific structs, function
prototypes and macros live in pmu.h.

So as to make their placement consistent and to make it easier to build
atop of the current PMU functionality, let's reunite the entire family in
pmu.h

Subject: arm: perf: add macros for empty event mappings

We currently map from userspace-ABI standard event numbers to
hardware-specific IDs by use of two arrays, *_perf_map and
*_perf_cache_map. While we use designated initializers to initialize the
events we care about, zero is typically a valid hardware event number,
and thus we have to explicitly initialize unsupported event mappings to a
nonzero value ({HW,CACHE}_OP_UNSUPPORTED).

In the case of the *_cache_map, this requires initialising almost every
entry in a 3-dimensional array to CACHE_OP_UNSUPPORTED, requiring over a
hundred lines to add eleven supported events in the case of Cortex A9.

So as to take up less space and make the tables easier to deal with,
this patch adds two new macros to initialize every entry in these tables
to the *_UNSUPPORTED values. Supported events can be overridden
individually through the use of designated initializers.

Subject: arm: perf: armv7: condense event maps

Now that we have macros for declaring fully invalid event maps, put them
to work for all the ARMv7 PMU event maps. While this necessitates
repeating common indices, we no longer need to refer to *_UNSUPPORTED
events at all, and it makes it possible for the even maps to fit on a
single page on a reasonably sized monitor.

Subject: arm: perf: armv6: condense event maps

Now that we have macros for declaring fully invalid event maps, put them
to work for all the ARMv6 PMU event maps. While this necessitates
repeating common indices, we no longer need to refer to *_UNSUPPORTED
events at all, and it makes it possible for the even maps to fit on a
single page on a reasonably sized monitor.

From 3d1ff755e36705ad9ec96f740edc08d20c3e9a87 Mon Sep 17 00:00:00 2001

Subject: arm: perf: clean up PMU names

The perf userspace tools can't handle dashes or spaces in PMU names,
which conflicts with the current naming scheme in the arm perf backend.
This prevents these PMUs from being accessed by name from the perf
tools. Additionally the ARMv6 pmus are named "v6", which does not fully
distinguish them in the sys/bus/event_source namespace.

This patch renames the PMUs consistently to a lower case form with
underscores, e.g. "armv6_1176", "armv7_cortex_a9". This is both readily
accepted by today's perf tool, and far easier to type than the
(apparently unused) convention in use previously. The OProfile name
conversion code is updated to handle this.

Due to a copy-paste error involving two "xscale1" entries, "xscale2" has
never been matched by the name OProfile name mapping. While we're
updating names, this is corrected.

Subject: arm: perf: add more specific platform device IDs

When described in DT, PMUs are given specific compatible strings
(e.g. "arm,cortex-a15-pmu") which makes it very easy to reorganise the
way individual PMUs are handled (i.e. we can easily split them into
separate drivers). The same is not true of PMUs described in board
files, which are all use the platform_device_id "arm-pmu" and must all
be handled by the same driver.

To enable splitting the ARMv6, ARMv7, and XScale PMU drivers we need
board files to identify which variant they provide. As a first step,
this patch adds new platform_device_id values: "armv6-pmu", "armv7-pmu,
and "xscale-pmu".

Once board files are moved over and all existing uses of "arm-pmu" are
gone, we can split the existing driver apart.

Currently the krait_pmu_{enable,disable}_event functions use the global
cpu_pmu variable while all the other pmu enable/disable functions
derive this from the event argument.

This patch brings the Krait functions into line with the rest of the PMU
backends by deriving the address of the pmu from the event argument.

Subject: powerpc/fsl-booke: Add support for T2080/T2081 SoC

The T2080 QorIQ multicore processor combines four dual-threaded e6500 Power
Architecture processor cores with high-performance datapath acceleration
logic and network and peripheral bus interfaces required for networking,
telecom/datacom, wireless infrastructure, and mil/aerospace applications.

The T2080 SoC includes the following function and features:
- Four dual-threaded 64-bit Power architecture e6500 cores, up to 1.8GHz
- 2MB L2 cache and 512KB CoreNet platform cache (CPC)
- Hierarchical interconnect fabric
- One 32-/64-bit DDR3/3L SDRAM memory controllers with ECC and interleaving
- Data Path Acceleration Architecture (DPAA) incorporating acceleration
- 16 SerDes lanes up to 10.3125 GHz
- 8 Ethernet interfaces (multiple 1G/2.5G/10G MACs)
- High-speed peripheral interfaces
  - Four PCI Express controllers (two PCIe 2.0 and two PCIe 3.0)
  - Two Serial RapidIO 2.0 controllers/ports running at up to 5 GHz
- Additional peripheral interfaces
  - Two serial ATA (SATA 2.0) controllers
  - Two high-speed USB 2.0 controllers with integrated PHY
  - Enhanced secure digital host controller (SD/SDXC/eMMC)
  - Enhanced serial peripheral interface (eSPI)
  - Four I2C controllers
  - Four 2-pin UARTs or two 4-pin UARTs
  - Integrated Flash Controller supporting NAND and NOR flash
- Three eight-channel DMA engines
- Support for hardware virtualization and partitioning enforcement
- QorIQ Platform's Trust Architecture 2.0

T2081 is a reduced personality of T2080 with following difference:
Feature               T2080 T2081
1G Ethernet numbers:  8     6
10G Ethernet numbers: 4     2
SerDes lanes:         16    8
Serial RapidIO,RMan:  2     no
SATA Controller:      2     no
Aurora:               yes   no
SoC Package:          896-pins 780-pins

Subject: KVM: PPC: BOOK3S: PR: Fix PURR and SPURR emulation

We use time base for PURR and SPURR emulation with PR KVM since we
are emulating a single threaded core. When using time base
we need to make sure that we don't accumulate time spent in the host
in PURR and SPURR value.

Also we don't need to emulate mtspr because both the registers are
hypervisor resource.

Patch d6d757c9a4e ("ARM: shmobile: APMU: Add Core-Standby-state for
Suspend to RAM") added both an inline wrapper for shmobile_smp_apmu_suspend_init
and an empty function in arch/arm/mach-shmobile/platsmp-apmu.c. We get a
build failure when both are present, so this patch removes the one in the .c
file and keeps the inline version.

Subject: ARM: sunxi: select MFD_SUN6I_PRCM when sun8i arch support is enabled

Select the MFD_SUN6I_PRCM option when sun8i arch is enabled in order to
get the PRCM (Power/Reset/Clock Management) related drivers compiled.

Also select ARCH_HAS_RESET_CONTROLLER and RESET_CONTROLLER to make sure
the reset controller drivers are compiled.

Subject: ARM: sun8i: Add reset controller nodes to the DTSI

The A23 has the same MMIO reset controllers matching the clocks gates,
just like in the A31. This patch adds the reset controller nodes and
the reset control phandles for the peripherals needing them to the
DTSI.

Unlike the sun6i DTSI, this patch uses sun6i-a31-clock-reset for
ahb1_rst. sun6i-a31-ahb-reset is for early init, and requires some
additions to the machine code. It is used to support the hstimer.
However the hstimer on sun8i only has 1 timer, which is somewhat
useless. Support for it will probably not be added. Hence the
decision to use sun6i-a31-clock-reset here to avoid the changes to
sun8i machine code.

Subject: omap16xx: Removes fixme no longer needed in ocpi_enable()

This removes the FIXME message above ocpi_enable being declared
for proper locking in this function. As of the current kernel
verisons there is no need for locking as only one driver uses
this function currently and therefore there is no need for real
locking requirements.

Subject: ARM: mvebu: add appended DTB support in mvebu_v5_defconfig

The mvebu_v5_defconfig is currently used for Kirkwood platforms, and
in the future hopefully used for Orion5x platforms. Those platforms
use fairly old bootloaders that don't have Device Tree support, so it
makes sense to enable appended DTB support by default, as well as the
backward compatibility with ATAGS passed by the bootloader for those
platforms. It helps having a defconfig that works fine out of the box
for most Kirkwood platforms.

Subject: ARM: OMAP4: Ctrl module register define diet

The mach-omap2 directory contains full register defines for OMAP4
control module but only around 27 of those are used. There are is
a total of 1795 register defines in four files with only 27 in use.
That is pretty low usefulness ratio...

I guess alot more was used when we had omap4 board files and
mach-omap2 contained more drivers but this has now changed.

Subject: ARM: dts: dra7: add routable-irqs property for gic node

There is a IRQ crossbar device in the soc, which maps the
irq requests from the peripherals to the mpu interrupt
controller's inputs. The gic provides the support for such
IPs in the form of routable-irqs. So adding the property
here to gic node.

Subject: ARM: dts: dra7: add crossbar device binding

There is a IRQ crossbar device in the soc, which
maps the irq requests from the peripherals to the
mpu interrupt controller's inputs. The Peripheral irq
requests are connected to only one crossbar
input and the output of the crossbar is connected to only one
controller's input line. The crossbar device is used to map
a peripheral input to a free mpu's interrupt controller line.

Here, adding a new crossbar device node and replacing all the peripheral
interrupt numbers with its fixed crossbar input lines.

Subject: ARM: perf: disable the pagefault handler when reading from user space

Under perf, the fp unwinding scheme requires access to user space memory
and can provoke a pagefault via call to __copy_from_user_inatomic from
user_backtrace. This unwinding can take place in response to an interrupt
(__perf_event_overflow). This is undesirable as we may already have
mmap_sem held for write. One example being a process that calls mprotect
just as a the PMU counters overflow.

An example that can provoke this behaviour:
perf record -e event:tocapture --call-graph fp ./application_to_test

This patch addresses this issue by disabling pagefaults briefly in
user_backtrace (as is done in the other architectures: ARM64, x86, Sparc etc.).

Without the patch a deadlock occurs when __perf_event_overflow is called
while reading the data from the user space:

Subject: ARM: at91/dt: sam9n12 crystals under the clocks node

Having clocks grouped in a subnode is common practice, so move the crystals
under a clocks node for the at91sam9n12 SoC and at91sam9n12 based boards.

From 93af052da51ed5fa5c74078a625e9ba11d95edd3 Mon Sep 17 00:00:00 2001
From: Alexandre Belloni <alexandre.belloni@free-electrons.com>
Date: Thu, 29 May 2014 20:44:44 +0200
Subject: ARM: at91: move at91rm9200 SoC to the CCF

This patch removes the selection of AT91_USE_OLD_CLK when selecting at91rm9200
SoC support. This will automatically enable COMMON_CLK_AT91 option and add
support for at91 common clk implementation.

Date: Thu, 29 May 2014 20:42:30 +0200
Subject: ARM: at91: move at91sam9260 SoCs to the CCF

This patch removes the selection of AT91_USE_OLD_CLK when selecting at91sam9260
SoCs support. This will automatically enable COMMON_CLK_AT91 option and add
support for at91 common clk implementation.

Subject: ARM: at91: move at91sam9g45 SoC to the CCF

This patch removes the selection of AT91_USE_OLD_CLK when selecting at91sam9g45
SoC support. This will automatically enable COMMON_CLK_AT91 option and add
support for at91 common clock implementation.

Subject: ARM: at91: move at91sam9263 SoC to the CCF

This patch removes the selection of AT91_USE_OLD_CLK when selecting
at91sam9263 SoC support. This will automatically enable COMMON_CLK_AT91
option and add support for at91 common clock implementation.

Subject: ARM: tegra: Add resets & has-utmi-pad-registers flag to all USB PHYs

Add new properties to all of the Tegra PHYs that are now required
according to the binding.

In order to stay compatible with old device trees, the USB drivers
will still function without these reset properties but with the old,
potentially buggy behaviour.

From 1e64f48ea7c59fb94acd7551dd9fa68b8a752efc Mon Sep 17 00:00:00 2001
From: Tomasz Figa <t.figa@samsung.com>
Date: Thu, 26 Jun 2014 13:24:35 +0200
Subject: ARM: dts: SAMSUNG: Add aliases of UART nodes

This patch adds alias entries for UART nodes of all SoCs using
samsung-uart compatible UART controllers, so that the dependency on
probe order is removed and deterministic device naming is assured.

Subject: ARM: ux500: remove pointless cache setup complexity

This cleans out non-DT cache setup (the ux500 is DT only), and
sinks the l2cc base into the unlock function.

Subject: ARC: [arcfpga] stdout-path now suffices for earlycon/console

With recent improvements to serial/of core from Grant and Rob,
stdout-path alone suffices for setting up earlycon/console.

arc_uart driver is already equipped to handle that, switch the DT now.

Subject: powerpc/pseries: Use jump labels for hcall tracepoints

hcall tracepoints add quite a few instructions to our hcall path:

plpar_hcall:
	mr      r2,r2
	mfcr    r0
	stw     r0,8(r1)
	b       164		<---- start
	ld      r12,0(r2)
	std     r12,32(r1)
	cmpdi   r12,0
	beq     164		<---- end
...

We have an unconditional branch that gets noped out during boot and
a load/compare/branch. We also store the tracepoint value to the
stack for the hcall_exit path to use.

By using jump labels we can simplify this to just a single nop that
gets replaced with a branch when the tracepoint is enabled:

plpar_hcall:
	mr      r2,r2
	mfcr    r0
	stw     r0,8(r1)
	nop			<----
...

If jump labels are not enabled, we fall back to the old method.

Subject: powernv: Add OPAL tracepoints

Knowing how long we spend in firmware calls is an important part of
minimising OS jitter.

This patch adds tracepoints to each OPAL call. If tracepoints are
enabled we branch out to a common routine that calls an entry and exit
tracepoint.

This allows us to write tools that monitor the frequency and duration
of OPAL calls, eg:

name                  count  total(ms)  min(ms)  max(ms)  avg(ms)  period(ms)
OPAL_HANDLE_INTERRUPT     5      0.199    0.037    0.042    0.040   12547.545
OPAL_POLL_EVENTS        204      2.590    0.012    0.036    0.013    2264.899

We use jump labels if configured, which means we only add a single
nop instruction to every OPAL call when the tracepoints are disabled.

Subject: ARM: shmobile: r8a7790: lager: use iic cores instead of i2c

On Lager board, i2c and iic cores can be interchanged since they can be
muxed to the same wires. Commit e489c2a9bc82713167d9f721ca764f4b0d37e543
("ARM: shmobile: lager: enable i2c devices") activated the i2c cores,
yet the iic cores should be default since they have the more interesting
features for generic use cases, i.e. SMBUS_QUICK and DMA (yet to be
supported).

Subject: arm/arm64: KVM: Fix and refactor unmap_range

unmap_range() was utterly broken, to quote Marc, and broke in all sorts
of situations.  It was also quite complicated to follow and didn't
follow the usual scheme of having a separate iterating function for each
level of page tables.

Address this by refactoring the code and introduce a pgd_clear()
function.

Subject: ARM: KVM: Unmap IPA on memslot delete/move

Currently when a KVM region is deleted or moved after
KVM_SET_USER_MEMORY_REGION ioctl, the corresponding
intermediate physical memory is not unmapped.

This patch corrects this and unmaps the region's IPA range
in kvm_arch_commit_memory_region using unmap_stage2_range.

Subject: ARM: KVM: user_mem_abort: support stage 2 MMIO page mapping

A userspace process can map device MMIO memory via VFIO or /dev/mem,
e.g., for platform device passthrough support in QEMU.

During early development, we found the PAGE_S2 memory type being used
for MMIO mappings.  This patch corrects that by using the more strongly
ordered memory type for device MMIO mappings: PAGE_S2_DEVICE.

I suspect this is a -ECUTPASTE fault from the initial implementation. If
we don't declare the register ID to be KVM_REG_ARM64 the KVM_GET_ONE_REG
implementation kvm_arm_get_reg() returns -EINVAL and hilarity ensues.

The kvm/api.txt document describes all arm64 registers as starting with
0x60xx... (i.e KVM_REG_ARM64).

Subject: arm64: KVM: allow export and import of generic timer regs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

For correct guest suspend/resume behaviour we need to ensure we include
the generic timer registers for 64 bit guests. As CONFIG_KVM_ARM_TIMER is
always set for arm64 we don't need to worry about null implementations.
However I have re-jigged the kvm_arm_timer_set/get_reg declarations to
be in the common include/kvm/arm_arch_timer.h headers.

Subject: KVM: ARM: vgic: split GICv2 backend from the main vgic code

Brutally hack the innocent vgic code, and move the GICv2 specific code
to its own file, using vgic_ops and vgic_params as a way to pass
information between the two blocks.

Subject: arm64: KVM: remove __kvm_hyp_code_{start,end} from hyp.S

We already have __hyp_text_{start,end} to express the boundaries
of the HYP text section, and __kvm_hyp_code_{start,end} are getting
in the way of a more modular world switch code.

Just turn __kvm_hyp_code_{start,end} into #defines mapping the
linker-emited symbols.

Subject: arm64: KVM: split GICv2 world switch from hyp code

Move the GICv2 world switch code into its own file, and add the
necessary indirection to the arm64 switch code.

Also introduce a new type field to the vgic_params structure.

Subject: arm64: KVM: move HCR_EL2.{IMO,FMO} manipulation into the vgic switch
 code

GICv3 requires the IMO and FMO bits to be tightly coupled with some
of the interrupt controller's register switch.

In order to have similar code paths, move the manipulation of these
bits to the GICv2 switch code.

Subject: ARM: KVM: fix vgic V7 assembler code to work in BE image

The vgic h/w registers are little endian; when BE asm code
reads/writes from/to them, it needs to do byteswap after/before.
Byteswap code uses ARM_BE8 wrapper to add swap only if
CONFIG_CPU_BIG_ENDIAN is configured.

Subject: ARM: KVM: handle 64bit values passed to mrcc or from mcrr
 instructions in BE case

In some cases the mcrr and mrrc instructions in combination with the ldrd
and strd instructions need to deal with 64bit value in memory. The ldrd
and strd instructions already handle endianness within word (register)
boundaries but to get effect of the whole 64bit value represented correctly,
rr_lo_hi macro is introduced and is used to swap registers positions when
the mcrr and mrrc instructions are used. That has the effect of swapping
two words.

Subject: ARM: KVM: one_reg coproc set and get BE fixes

Fix code that handles KVM_SET_ONE_REG, KVM_GET_ONE_REG ioctls to work in BE
image. Before this fix get/set_one_reg functions worked correctly only in
LE case - reg_from_user was taking 'void *' kernel address that actually could
be target/source memory of either 4 bytes size or 8 bytes size, and code copied
from/to user memory that could hold either 4 bytes register, 8 byte register
or pair of 4 bytes registers.

In order to work in endian agnostic way reg_from_user to reg_to_user functions
should copy register value only to kernel variable with size that matches
register size. In few place where size mismatch existed fix issue on macro
caller side.

Subject: ARM64: KVM: store kvm_vcpu_fault_info est_el2 as word

esr_el2 field of struct kvm_vcpu_fault_info has u32 type.
It should be stored as word. Current code works in LE case
because existing puts least significant word of x1 into
esr_el2, and it puts most significant work of x1 into next
field, which accidentally is OK because it is updated again
by next instruction. But existing code breaks in BE case.

Subject: ARM64: KVM: set and get of sys registers in BE case

Since size of all sys registers is always 8 bytes. Current
code is actually endian agnostic. Just clean it up a bit.
Removed comment about little endian. Change type of pointer
from 'void *' to 'u64 *' to enforce stronger type checking.

Subject: ARM64: KVM: fix big endian issue in access_vm_reg for 32bit guest

Fix issue with 32bit guests running on top of BE KVM host.
Indexes of high and low words of 64bit cp15 register are
swapped in case of big endian code, since 64bit cp15 state is
restored or saved with double word write or read instruction.

Define helper macro to access low words of 64bit cp15 register.

Subject: arm64: KVM: rename pm_fake handler to trap_raz_wi

pm_fake doesn't quite describe what the handler does (ignoring writes
and returning 0 for reads).

As we're about to use it (a lot) in a different context, rename it
with a (admitedly cryptic) name that make sense for all users.

Subject: arm64: move DBG_MDSCR_* to asm/debug-monitors.h

In order to be able to use the DBG_MDSCR_* macros from the KVM code,
move the relevant definitions to the obvious include file.

Also move the debug_el enum to a portion of the file that is guarded
by #ifndef __ASSEMBLY__ in order to use that file from assembly code.

Subject: arm64: KVM: add trap handlers for AArch64 debug registers

Add handlers for all the AArch64 debug registers that are accessible
from EL0 or EL1. The trapping code keeps track of the state of the
debug registers, allowing for the switch code to implement a lazy
switching strategy.

Subject: arm64: KVM: use separate tables for AArch32 32 and 64bit traps

An interesting "feature" of the CP14 encoding is that there is
an overlap between 32 and 64bit registers, meaning they cannot
live in the same table as we did for CP15.

Create separate tables for 64bit CP14 and CP15 registers, and
let the top level handler use the right one.

Subject: arm64: KVM: implement lazy world switch for debug registers

Implement switching of the debug registers. While the number
of registers is massive, CPUs usually don't implement them all
(A57 has 6 breakpoints and 4 watchpoints, which gives us a total
of 22 registers "only").

Also, we only save/restore them when MDSCR_EL1 has debug enabled,
or when we've flagged the debug registers as dirty. It means that
most of the time, we only save/restore MDSCR_EL1.

Subject: arm64: KVM: enable trapping of all debug registers

Enable trapping of the debug registers, preventing the guests to
mess with the host state (and allowing guests to use the debug
infrastructure as well).

Subject: pinctrl: i.MX27: Remove nonexistent pad definitions

Pads for PB0-PB3, PC0-PC4, PE26-PE31 and PF24-PF31 does not exist on
the i.MX27 SOC. There is no reason to define them, the presence of
such definitions in the DTS files is a bug.
This patch removes these nonexistent pad definitions.

Subject: pinctrl: sunxi: Remove PINCTRL_SUNXI

The PINCTRL_SUNXI configuration was kept only to deal with the introduction of
per-machine symbols and the various pintrl drivers through different tree.

Now that it's not useful anymore, we can just remove it.

Subject: ARM: omap2+: gpmc-nand: Use dynamic platform_device_alloc()

GPMC controller supports up to 8 memory devices connected to it.
Since there is one statically allocated "struct platform_device
gpmc_nand_device" it is not possible to configure the system to
use more than one NAND device connected to the GPMC. This
modification makes it possible to use up to 8 NAND devices
connected to the GPMC controller.

the iotable mappings should be re-located inside the vmalloc
region. Such move was introduced at commit:

Subject: ARM: Kirkwood: allow to use netxbig DTSI for d2net_v2 DTS

The d2 Network v2 board (d2net_v2) shares a lot of hardware
characteristics with the 2Big and 5Big Network v2 boards. This patch
prepares the kirkwood-netxbig.dtsi file in order to allow to include it
from the d2net_v2 DTS file. The DT nodes only relevant for the 2Big and
5Big Network v2 boards are moved into their respective DTS files.

Subject: ARM: Kirkwood: add DT support for d2 Network v2

This patch adds DT support for the LaCie NAS d2 Network v2 (d2net_v2).
Most of the hardware characteristics are shared with the 2Big and 5Big
Network v2 boards.

- CPU: Marvell 88F6281 1200Mhz
- SDRAM memory: 256MB DDR2 400Mhz
- 2 SATA ports: internal and eSATA
- Gigabit ethernet: PHY Marvell 88E1116R
- Flash memory: SPI NOR 512KB (Macronix MX25L4005A)
- i2c EEPROM: 512 bytes (24C04 type)
- 2 USB2 ports: host and host/device
- 1 push button
- 1 power switch
- 1 SATA LED (bi-color, blue and red)

Subject: x86, vsmp: Remove is_vsmp_box() from apic_is_clustered_box()

When a vSMP Foundation box is detected, the function apic_cluster_num() counts
the number of APIC clusters found. If more than one found, a multi board
configuration is assumed, and TSC marked as unstable. This behavior is
incorrect as vSMP Foundation may use processors from single node only, attached
to memory of other nodes - and such node may have more than one APIC cluster
(typically any recent intel box has more than single APIC_CLUSTERID(x)).

To fix this, we simply remove the code which detects a vSMP Foundation box and
affects apic_is_clusted_box() return value. This can be done because later the
kernel checks by itself if the TSC is stable using the
check_tsc_sync_[source|target]() functions and marks TSC as unstable if needed.

Subject: ARM: SPEAr13xx: Fix static mapping table

SPEAr13xx was using virtual address space 0xFE000000 to map physical address
space 0xB3000000. But pci_remap_io uses 0xFEE00000 as virtual address and so
replace 0xFE000000 with 0xF9000000.

Subject: ARM: SPEAr13xx: Add pcie and miphy DT nodes

This patch adds necessary DT nodes for pcie controllers and miphys for SPEAr13xx
SoCs.

SPEAr1310 has 3 PCIe ports and SPEAr1340 has 1, which are multiplexed with
ahci/sata pins. By default evaluation board of both controller works in ahci
mode. Because of this, these nodes are marked "disabled" by default.

In order to use pcie controller on evaluation boards do necessary modifications
on board and enable (By replacing "disabled" with "okay") pcie and miphy from
respective 'evb' dtsi file.

Phy specific initialization was previously done from spear1340.c, which isn't
required anymore as we have separate drivers for it. Remove it.

Subject: xen: Introduce 'xen_nopv' to disable PV extensions for HVM guests.

By default when CONFIG_XEN and CONFIG_XEN_PVHVM kernels are
run, they will enable the PV extensions (drivers, interrupts, timers,
etc) - which is the best option for the majority of use cases.

However, in some cases (kexec not fully working, benchmarking)
we want to disable Xen PV extensions. As such introduce the
'xen_nopv' parameter that will do it.

This parameter is intended only for HVM guests as the Xen PV
guests MUST boot with PV extensions. However, even if you use
'xen_nopv' on Xen PV guests it will be ignored.

Subject: x86: intel-mid: Use the new io_apic interfaces

Commit 9f354b0252b8 "x86, irq: Clean up unused IOAPIC interface" kills
interface io_apic_set_pci_routing(), so change arch/x86/platform/
intel-mid/device_libs/platform_wdt.c to use new interfaces.

Due to hardware resource restriction, this patch only passes compilation
without functional tests.

Subject: x86/xen: safely map and unmap grant frames when in atomic context

arch_gnttab_map_frames() and arch_gnttab_unmap_frames() are called in
atomic context but were calling alloc_vm_area() which might sleep.

Also, if a driver attempts to allocate a grant ref from an interrupt
and the table needs expanding, then the CPU may already by in lazy MMU
mode and apply_to_page_range() will BUG when it tries to re-enable
lazy MMU mode.

These two functions are only used in PV guests.

Introduce arch_gnttab_init() to allocates the virtual address space in
advance.

Avoid the use of apply_to_page_range() by using saving and using the
array of PTE addresses from the alloc_vm_area() call.

N.B. 'alloc_vm_area' pre-allocates the pagetable so there is no need
to worry about having to do a PGD/PUD/PMD walk (like apply_to_page_range
does) and we can instead do set_pte.

Subject: xen/grant-table: remove support for V2 tables

Since 11c7ff17c9b6dbf3a4e4f36be30ad531a6cf0ec9 (xen/grant-table: Force
to use v1 of grants.) the code for V2 grant tables is not used.

Subject: ARM: debug: Update Samsung UART config options

In a multiplatform config, the low level debug option shows several
UART port entries. Improve the user visible string so that it becomes
clear to the user about Samsung UART ports.
While at it also remove some lines from the help text that are no
longer applicable across all Samsung platforms.

Subject: ARM: EXYNOS: Remove regs-pmu.h header dependency from pm_domain

Current "pm_domain.c" file uses "S5P_INT_LOCAL_PWR_EN" definition from
"regs-pmu.h" and hence needs to include this header file. As there is
no other user of "S5P_INT_LOCAL_PWR_EN" definition other than pm_domain,
to remove "regs-pmu.h" header file dependency from "pm_domain.c"  it's
better we define this definition in "pm_domain.c" file itself and thus it
will help in removing header file inclusion from "pm_domain.c".
Also removing "S5P_" prefix from macro.

Subject: ARM: dts: dra7xx-clocks: Add divider table to optfclk_pciephy_div
 clock

Add divider table to optfclk_pciephy_div clock. The 8th bit of
CM_CLKMODE_APLL_PCIE can be programmed to either 0x0 or 0x1
based on if the divider value is 0x2 or 0x1.

Figure 26-21. PCIe PHY Clock Generator Overview in vE of DRA7xx ES1.0 shows the
block diagram of Clock Generator Subsystem of PCIe PHY module. The divider
value if '1' should be programmed in order to get the correct
PCIE_PHY_DIV_GCLK frequency (2.5GHz).

Subject: ARM: dts: dra7xx-clocks: Change the parent of apll_pcie_in_clk_mux to
 dpll_pcie_ref_m2ldo_ck

Change the parent of apll_pcie_in_clk_mux to dpll_pcie_ref_m2ldo_ck
from dpll_pcie_ref_ck.

Figure 26-22. DPLL_PCIE_REF Functional Block Diagram in vE of DRA7xx ES1.0 TRM
shows the signal name for the output of post divider (M2) is CLKOUTLDO.

Figure 26-21. PCIe PHY Clock Generator Overview shows CLKOUTLDO is used as
input to apll mux.

So the actual output of dpll is dpll_pcie_ref_m2ldo_ck which is also the input
of apll.

Subject: ARM: dts: dra7xx-clocks: rename pcie clocks to accommodate second PHY
 instance

There are two instances of PCIe PHY in DRA7xx. So renamed
optfclk_pciephy_32khz, optfclk_pciephy_clk and optfclk_pciephy_div_clk to
optfclk_pciephy1_32khz, optfclk_pciephy1_clk and optfclk_pciephy1_div_clk
respectively. This is needed for adding the clocks for second PCIe PHY
instance.

Subject: ARM: DTS: omap5-uevm: Enable basic audio (McPDM <-> twl6040)

The board uses twl6040 codec connected via McPDM link. McBSP1 and McBSP2 can
be used for FM/BT.
At the same time move the pinctrl handling to the correct place - under the
corresponding nodes.
Audio connectors on the board:
Headset in/out
Stereo Line out
Stereo Line in.

From 41ffada18f77b3309603dfff6a719b5b8425de3b Mon Sep 17 00:00:00 2001
From: Suman Anna <s-anna@ti.com>

Subject: ARM: dts: OMAP2+: Add mailbox fifo and user information

The number of mailbox fifos and users (IP interrupts) are added
to the Mailbox DT nodes on OMAP2420, OMAP2430, OMAP3, and OMAP5
family of SoCs through the DT properties "ti,mbox-num-fifos" and
"ti,mbox-num-users" properties. This data represents the same data
that used to be represented in hwmod attribute data through the
.num_fifos and .num_users fields previously.

Subject: ARM: dts: DRA7: Add mailbox nodes

DRA7xx has 13 system mailboxes, and is present on both the
DRA72x and DRA74x family of SoCs. Add the DT nodes for all
these 13 mailboxes. Except for mailbox 1, all other mailboxes
do not have interrupts mapped into the MPU GIC by default.

All the mailboxes have been disabled and the interrupts
property information is left out intentionally for now,
because of the dependencies against the crossbar driver.
These mailboxes can be enabled when a usecase arises
and the crossbar driver dependencies are met.

NOTE: The mailbox 1 has different number of mailbox fifos
and IP interrupts compared to the remaining 12 mailboxes.

Subject: ARM: DRA7: hwmod_data: Add mailbox hwmod data

Add the hwmod data for the 13 instances of the system mailbox
IP in DRA7 SoC. The patch is needed for performing a soft-reset
while configuring the respective mailbox instance, otherwise is
a non-essential change for functionality. The modules are smart
idled on reset, and the IP module mode is hardware controlled.

Subject: ARM: OMAP2: hwmod_data: Remove legacy mailbox data and addrs

OMAP2 devices are devicetree boot only, and the legacy mode
of mailbox device creation should no longer be used, so remove
the mailbox attribute data and the hwmod addr space used for
creating mailboxes in legacy mode.

Subject: ARM: dts: Add mask-tpm-reset node in exynos5420-peach-pit

The mask-tpm-reset GPIO is used by the kernel to prevent the TPM from
being reset across sleep/wake.  If we don't set it to anything then
the TPM will be reset.  U-Boot will detect this as invalid
and will reset the system on resume time. This GPIO can always be low
and not hurt anything.  It will get pulled back high again during a
normal warm reset when it will default back to an input.

To properly preserve the TPM state across suspend/resume and to make
the chrome U-Boot happy, properly set the GPIO to mask the
reset to the TPM.

Subject: ARM: dts: Add mask-tpm-reset node in exynos5800-peach-pi

The mask-tpm-reset GPIO is used by the kernel to prevent the TPM from
being reset across sleep/wake.  If we don't set it to anything then
the TPM will be reset.  U-Boot will detect this as invalid
and will reset the system on resume time. This GPIO can always be low
and not hurt anything.  It will get pulled back high again during a
normal warm reset when it will default back to an input.

To properly preserve the TPM state across suspend/resume and to make
the chrome U-Boot happy, properly set the GPIO to mask the
reset to the TPM.

Subject: ARM: dts: refactor Odroid DTS file and add support for Odroid X2 and
 U2/U3

This patch moves some parts of exynos4412-odroidx.dts to common
exynos4412-odroid-common.dtsi file and adds support for Odroid X2 and
U2/U3 boards. X2 is same as X, but it has faster SoC module (1.7GHz
instead of 1.4GHz), while U2/U3 differs from X2 by different way of
routing signals to host USB hub. It also lacks some hw modules not yet
supported by those dts files (i.e. LCD & touch panel).

Subject: ARM: dts: disable 'always on' for BUCK8 regulator for
 exynos4412-odroid-common

On Odroid U2/U3 BUCK8 is used for providing power to also to P3V3
source, which is also connected to LAN9730 chip's nRESET signal. To
reset lan chip on system reboot, the BUCK8 output should not be used in
'always on' mode. This change has no impact on X/X2 boards.

Subject: ARM: dts: add support for GPIO buttons for exynos4412-odroid

This patch adds support for simple GPIO-based button availabled on
Exynos4 based Odroid boards. All supported boards have POWER button,
which has been defined in exynos4412-odroid-common.dtsi. X/X2 boards
also have additional user-configurable button which has been mapped to
KEY_HOME. All defined keys have been marked as possible wakeup source.

Subject: ARM: dts: fix T-FLASH hotplug detection for exynos4412-odroid-common

TFLASH (SDHCI2 controller) uses internal card detect line, but it looks
that the driver fails to operate it properly. Use GPIO interrupt on
SD_CDn line for detecting SD card state.

These are unnecessary, as the clock code is only used on OMAP4+ platforms
through clock registrations. This also allows to eventually migrate the
clock type implementation under clock driver.

Subject: ARM: OMAP2+: clock/dpll: add private API for checking if DPLL is in
 bypass

Currently, same functionality is copy pasted in two locations. Instead,
add a private API for this and get rid of some duplicated code.

Subject: ARM: OMAP2+: clock/dpll: convert bypass check to use clk_features

OMAP2 DPLL code for checking whether DPLL is in bypass mode now uses
clk_features data provided during boot. This avoids the need to use
cpu_is_X type checks runtime, and allows us to eventually move the
clock code under the clock driver.

Subject: ARM: OMAP2+: clock/dpll: add jitter correction behind clk_features

Currently DPLL code uses runtime cpu_is_343x checks to see if the DPLL
has freqsel fields in its control register or not. Instead, add a new
flag to the clk_features.flags and use this during runtime. Allows
eventual move of the DPLL code under clock driver.

Subject: ARM: dts: remove display power domain for exynos5420

Display domain is removed due to instability issues. Explaining
the problem below:

exynos_init_late triggers the pm_genpd_poweroff_unused which powers
off the unused power domains. This call hits before the trigger to
deferred probes.

DRM DP Panel defers the probe due to supply get failure. By the time,
deferred probe is scheduled again, Display Power Domain is powered
off by pm_genpd_poweroff_unused.

FIMD and DP drivers are accessing registers during Probe and Bind
callbacks. If display domain is enabled/disabled around register
accesses, display domain gets unstable and we are getting Power Domain
Disable fail notification. Increasing the Timeout also didn't help.

Subject: ARM: OMAP2+: remove DSP platform device
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

It was added to support DSP Bridge. Since DSP Bridge was removed, and
nothing else is using the platform device, remove it too.

Subject: ARM: mvebu: add CA9 MPcore SoC Controller node

The CA9 MPcore SoC Control block is a set of registers that allows to
configure certain internal aspects of the core blocks of the SoC
(Cortex-A9, L2 cache controller, etc.). In most cases, the default
values are fine so they aren't many reasons to touch those registers,
but there is one exception: to support cpuidle on Armada 38x, we need
to modify the value of the CA9 MPcore Reset Control register.

Therefore, this commit adds a new Device Tree binding for this
hardware block, and uses this new binding for the Armada 38x Device
Tree file.

Now that the Armada XP supports dynamic CPU frequency scaling, it
makes sense to enable the cpufreq subsystem in mvebu_v7_defconfig, as
well as the cpufreq-generic driver used on Armada XP.

Subject: ARM: mvebu: update Armada XP DT for dynamic frequency scaling

In order to support dynamic frequency scaling:

 * the cpuclk Device Tree node needs to be updated to describe a
   second set of registers describing the PMU DFS registers.

 * the clock-latency property of the CPUs must be filled, otherwise
   the ondemand and conservative cpufreq governors refuse to work. The
   latency is high because the cost of a frequency transition is quite
   high on those CPUs.

Subject: ARM: mvebu: ensure CPU clocks are enabled

In the Armada XP SMP support code, we are reading the clock frequency
of the booting CPU, and use that to assign the same frequency to the
other CPUs, and we do this while the clocks are disabled.

However, the CPU clocks are in fact never prepared/enabled, and to
support cpufreq, we now have two code paths to change the frequency of
the CPU clocks in the CPU clock driver: one when the clock is enabled
(dynamic frequency scaling), one when the clock is disabled (adjusting
the CPU frequency before starting the CPU). In order for this to work,
the CPU clocks now have to be prepared and enabled after the initial
synchronization of the clock frequencies is done, so that all future
rate changes of the CPU clocks will trigger a dynamic frequency
scaling transition.

Subject: ARM: mvebu: extend PMSU code to support dynamic frequency scaling

This commit adds the necessary code in the Marvell EBU PMSU driver to
support dynamic frequency scaling. In essence, what this new code does
is that it:

 * registers the frequency operating points supported by the CPU;

 * registers a clock notifier of the CPU clocks. The notifier function
   listens to the newly introduced APPLY_RATE_CHANGE event, and uses
   that to finalize the frequency transition by doing the part of the
   procedure that involves the PMSU;

 * registers a platform device for the cpufreq-generic driver, which
   will take care of the CPU frequency transitions.

From a0524acc94c91c72c2968a76eddc6f3afe82f9f2 Mon Sep 17 00:00:00 2001
From: Thierry Reding <treding@nvidia.com>
Date: Fri, 11 Jul 2014 09:44:49 +0200
Subject: ARM: tegra: Sort includes alphabetically

If these aren't sorted alphabetically, then the logical choice is to
append new ones, however that creates a lot of potential for conflicts
because every change will then add new includes in the same location.

Signed-off-by: Thierry Reding <treding@nvidia.com>

From 304664eab93f9e95a8d28fbd9702ede88bb10cc5 Mon Sep 17 00:00:00 2001
From: Thierry Reding <treding@nvidia.com>
Date: Fri, 11 Jul 2014 09:52:41 +0200
Subject: ARM: tegra: Use a function to get the chip ID

Instead of using a simple variable access to get at the Tegra chip ID,
use a function so that we can run additional code. This can be used to
determine where the chip ID is being accessed without being available.
That in turn will be handy for resolving boot sequence dependencies in
order to convert more code to regular initcalls rather than a sequence
fixed by Tegra SoC setup code.

Subject: ARM: tegra: export apb dma readl/writel

Export APB DMA readl and writel. These are needed because we can't
access the fuses directly on Tegra20 without potentially causing a
system hang. Also have the APB DMA readl and writel return an error in
case of a read failure instead of just returning zero or ignore write
failures.

Subject: ARM: tegra: move fuse exports to soc/tegra/fuse.h

All fuse related functionality will move to a driver in the following
patches. To prepare for this, export all the required functionality in a
global header file and move all users of fuse.h to soc/tegra/fuse.h.

While we're at it, remove tegra_bct_strapping, as its only user was
removed in Commit a7cbe92cef27 ("ARM: tegra: remove tegra EMC scaling
driver").

Subject: soc/tegra: Add efuse driver for Tegra

Implement fuse driver for Tegra20, Tegra30, Tegra114 and Tegra124. This
replaces functionality previously provided in arch/arm/mach-tegra, which
is removed in this patch.

While at it, move the only user of the global tegra_revision variable
over to tegra_sku_info.revision and export tegra_fuse_readl() to allow
drivers to read calibration fuses.

+What:		/sys/devices/*/<our-device>/fuse
+Date:		February 2014
+Contact:	Peter De Schrijver <pdeschrijver@nvidia.com>
+Description:	read-only access to the efuses on Tegra20, Tegra30, Tegra114
+		and Tegra124 SoC's from NVIDIA. The efuses contain write once
+		data programmed at the factory. The data is layed out in 32bit
+		words in LSB first format. Each bit represents a single value
+		as decoded from the fuse registers. Bits order/assignment
+		exactly matches the HW registers, including any unused bits.
+Users:		any user space application which wants to read the efuses on
+		Tegra SoC's

+NVIDIA Tegra20/Tegra30/Tegr114/Tegra124 fuse block.
+
+Required properties:
+- compatible : should be:
+	"nvidia,tegra20-efuse"
+	"nvidia,tegra30-efuse"
+	"nvidia,tegra114-efuse"
+	"nvidia,tegra124-efuse"
+  Details:
+  nvidia,tegra20-efuse: Tegra20 requires using APB DMA to read the fuse data
+	due to a hardware bug. Tegra20 also lacks certain information which is
+	available in later generations such as fab code, lot code, wafer id,..
+  nvidia,tegra30-efuse, nvidia,tegra114-efuse and nvidia,tegra124-efuse:
+	The differences between these SoCs are the size of the efuse array,
+	the location of the spare (OEM programmable) bits and the location of
+	the speedo data.
+- reg: Should contain 1 entry: the entry gives the physical address and length
+       of the fuse registers.
+- clocks: Must contain an entry for each entry in clock-names.
+  See ../clocks/clock-bindings.txt for details.
+- clock-names: Must include the following entries:
+  - fuse
+- resets: Must contain an entry for each entry in reset-names.
+  See ../reset/reset.txt for details.
+- reset-names: Must include the following entries:
+ - fuse
+
+Example:
+
+	fuse@7000f800 {

Subject: soc/tegra: fuse: move APB DMA into Tegra20 fuse driver

The Tegra20 fuse driver is the only user of tegra_apb_readl_using_dma().
Therefore we can simply the code by incorporating the APB DMA handling into
the driver directly. tegra_apb_writel_using_dma() is dropped because there
are no users.

Subject: ARM: tegra: Setup CPU hotplug in a pure initcall

CPU hotplug support doesn't have to be set up until fairly late in the
boot process, so it can be done in a regular initcall. To make sure that
we don't miss any ordering problems in the future, output a warning if
any of the functions are called before initialization has completed.

This is part of untangling the boot order dependencies on Tegra so that
more code can be shared between 32-bit and 64-bit ARM.

Subject: ARM: tegra: Always lock the CPU reset vector

Currently the reset vector is not locked on Tegra20 because the hardware
doesn't support it. However in order not to depend on the chip ID, which
becomes available only later in the boot process, we set the bit anyway.

Subject: soc/tegra: fuse: Set up in early initcall

Rather than rely on explicit initialization order called from SoC setup
code, use a plain initcall and rely on initcall ordering to take care of
dependencies.

This driver exposes some functionality (querying the chip ID) needed at
very early stages of the boot process. An early initcall is good enough
provided that some of the dependencies are deferred to later stages. To
make sure any abuses are easily caught, output a warning message if the
chip ID is queried while it can't be read yet.

From 6d0a067ff0f879a3a569c00219af25ba643727cb Mon Sep 17 00:00:00 2001
From: Marcel Ziswiler <marcel@ziswiler.com>
Date: Tue, 10 Jun 2014 00:52:46 +0200
Subject: ARM: tegra: initial support for apalis t30

This patch adds the device tree to support Toradex Apalis T30, a
computer on module which can be used on different carrier boards.

The module consists of a Tegra 3 SoC, two PMICs, 1 or 2 GB of DDR3L
RAM, eMMC, an LM95245 temperature sensor chip, an i210 resp. i211
gigabit Ethernet controller, an STMPE811 ADC/touch controller as well
as two MCP2515 CAN controllers. Furthermore, there is an SGTL5000 audio
codec which is not yet supported. Anything that is not self contained
on the module is disabled by default.

The device tree for the Evaluation Board includes the modules device
tree and enables the supported peripherals of the carrier board (the
Evaluation Board supports almost all of them).

While at it also add the device tree binding documentation for Apalis
T30.

Subject: ARM: tegra: tamonten: add the base board regulators

Currently the Tamonten DTS define a fixed regulator for the 5V supply.
However this regulator is in fact on the base board. Fix this by
properly defining the regulators found on the base boards.

Subject: ARM: tegra: roth: fix unsupported pinmux properties

The pinmux subsystem complained that the nvidia,low-power-mode property
is not supported by the sdio1, sdio3 and gma drive groups. In addition
gma also does not support nvidia,drive-type. Remove these properties so
the pinmux configuration can properly be applied.

The device tree node in the SoC file contains only the resources (such

since that's board specific and belongs in the board file.

Subject: ARM: tegra: Fix typoed ams,ext-control properties

The property for enabling external rail control on the AS3722 is
ams,ext-control, not ams,external-control. Since the external rail
control property was previously being ignored, LP1 suspend on these
boards wasn't actually turning the CPU rail off at all.

Subject: ARM: dts: keystone-evm: add 1g ethernet phys nodes

Keystone EVMK2HX has two 1G Marvell 88E1111 Ethernet PHYs
installed, so add corresponding child nodes for 1G MDIO bus
and enable it.

Subject: ARM: dts: fix the chip select gpios definition in the SPI nodes

This patch replaces the "cs-gpio" from "controller-data" node
as was specified in the old binding and uses the standard
"cs-gpios" property expected by the SPI core as is defined now
in the spi-s3c64xx driver DT binding.

Subject: tgt: defconfig cleanup

Because of the removal of the scsi_tgt kernel module, the kbuild variables
CONFIG_SCSI_TGT, CONFIG_SCSI_SRP_TGT_ATTRS and CONFIG_SCSI_FC_TGT_ATTRS
are obsolete. This patch removes these variables. This patch is the result
of the following command:

find -name '*defconfig' | while read f; do grep -vwE 'CONFIG_SCSI_TGT|CONFIG_SCSI_SRP_TGT_ATTRS|CONFIG_SCSI_FC_TGT_ATTRS|CONFIG_SRP' $f >/tmp/t && mv /tmp/t $f; done

Subject: ARM: i.MX: Select HAVE_IMX_SRC for i.MX5 globally

No reason to choose a symbol HAVE_IMX_SRC separately for each supported
i.MX5 CPU, this patch selects this symbol globally for i.MX5.

+Required properties:
+- compatible: Should be "fsl,imx1-ccm".
+- reg: Address and length of the register set.
+- #clock-cells: Should be <1>.
+
+The clock consumer should specify the desired clock by having the clock

Subject: ARM: imx: move EHCI platform defines out of platform_data header

The platform_data header usb-ehci-mxc.h has a lot of stuff used by only
IMX platform code.  They shouldn't be really in this header but a IMX
platform local header.  Create ehci.h and move these stuff into it.

From 50e177cae2b40c26ce956074dcd2d7384437e27e Mon Sep 17 00:00:00 2001
From: Shawn Guo <shawn.guo@freescale.com>
Date: Mon, 19 May 2014 13:37:50 +0800
Subject: ARM: imx5: move SOC_IMX5 and SOC_IMX51 into 'Device tree only'

After moving SOC_IMX51 support over to device tree, all i.MX5 support
becomes device tree only now.  So options SOC_IMX5 and SOC_IMX51 can
just be under 'Device tree only'.

While at it, 'select ARCH_MXC_IOMUX_V3' is dropped, since it's only
needed by non-DT build before.

Subject: ARM: imx5: drop option MACH_IMX51_DT

Since i.MX51 becomes DT only now, we can drop option MACH_IMX51_DT and
just use SOC_IMX51 instead.  While at it, rename imx51-dt.c to
mach-imx51.c to align with the name schema of other IMX DT only
platforms.

From c16cc8a0e90e91f250fabf08e2c772e3ce4dca74 Mon Sep 17 00:00:00 2001
From: Shawn Guo <shawn.guo@freescale.com>
Date: Mon, 19 May 2014 15:43:42 +0800
Subject: ARM: imx5: make mx51_clocks_init() a DT call

Since i.MX51 becomes a DT only platform, we can make mx51_clocks_init()
a DT call and save function mx51_clocks_init_dt() now.

Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

Subject: ARM: imx5: drop arguments from mx5_clocks_common_init()

The function mx5_clocks_common_init() was created with a number of
arguments to pass oscillator clock rate in non-DT boot.  Since i.MX5
is DT only platform, the arguments can be dropped, and the clock rate
can just be retrieved from device tree.

Subject: ARM: imx5: tzic_init_irq() can directly be .init_irq hook

After i.MX51 supports DT only, tzic_init_irq() can figure out the
tzic_base on its own.  Thus, it can directly be .init_irq hook, and
mx51[53]_init_irq() can be saved.

Subject: ARM: imx5: use dynamic mapping for CCM block

Replace the static mapping of CCM block with dynamic mapping and
retrieve CCM base address from device tree.  Though it's not nice to
encode the variable ccm_base in macros, it helps to avoid a massive
churn on the code.

Subject: ARM: imx5: use dynamic mapping for DPLL block

Replace the static mapping of DPLL block with dynamic mapping by
calling ioremap().  Ideally, this should be done by calling of_iomap(),
so that the physical address of DPLL can also be retrieved from device
tree.  But unfortunately, DPLL blocks are not defined in DT in the first
place.  So to maintain the compatibility of existing DTB, we use
ioremap() with physical address defines in the code.

Subject: ARM: imx5: reuse clock CCM mapping in pm code

The imx5 pm code needs to access CCM registers.  Let's remove the use
of CCM static mapping in pm code by reusing the dynamic mapping created
in clock code.

Subject: ARM: imx5: use dynamic mapping for Cortex and GPC block

The imx5 pm code uses static mapping to access Cortex and GPC registers.
The patch create struct imx5_pm_data to encode physical address of
Cortex and GPC block, and create dynamic mapping for them at run-time.

Subject: ARM: imx5: move init hooks into mach-imx5x.c

These imx5 init_early[late] hooks are called only from mach-imx5x.c.
Let's move them into mach-imx5x.c.

While at it, replace the static mapping in imx51_ipu_mipi_setup() with
dynamic mapping.  Also this function and imx_src_init() do not
necessarily to be called at .init_early hook, so move them into
.init_machine.

The mxc_iomux_v3_init() is dropped from imx51_init_early() in the
moving, since it's only needed by non-DT boot.

Subject: ARM: imx5: remove file mm-imx5.c

The only code left in mm-imx5.c is to create static mapping.  While all
IMX platform code are moved to use dynamic mapping, the file can just be
removed now.

Subject: ARM: imx: defconfig: Select CONFIG_FHANDLE

CONFIG_FHANDLE=y is needed when running systemd with version >=210, so that it
can spawn a serial tty via getty.

Subject: ARM: i.MX: Use of_clk_get_by_name() for timer clocks for DT case.

Use of_clk_get_by_name() for timer clocks for DT case.
This patch eliminates a lot of unneeded clk_register_clkdev()
calls for GPT.

Subject: ARM: i.MX: Remove Freescale i.MX27 IP Camera board support

The board has no insufficient support to be fully functional and seems
has no users. This patch removes support for this board. However, the
support may be added in the future by using the devicetree.

Subject: ARM: imx: add standby mode support for suspend

Add standby mode support for suspend, to enter standby mode:

echo standby > /sys/power/state;

Use UART or RTC alarm to wake up system, when system enters
standby mode, SOC will enter STOP mode with ARM core kept
power on and 24M XTAL on.

Subject: ARM: clk-imx51-imx53: Remove clk_register_clkdev()

mx51 and mx53 are device tree only platforms, so we no longer need all these
calls to clk_register_clkdev().

Only keep cpu0 and gpc_dvfs clk_register_clkdev() calls.

Tested on imx51-babbage and imx53-qsb boards.

+* Clock bindings for Freescale i.MX21
+
+Required properties:
+- compatible  : Should be "fsl,imx21-ccm".
+- reg         : Address and length of the register set.
+- interrupts  : Should contain CCM interrupt.
+- #clock-cells: Should be <1>.
+
+The clock consumer should specify the desired clock by having the clock
+ID in its "clocks" phandle cell. See include/dt-bindings/clock/imx21-clock.h
+for the full list of i.MX21 clock IDs.
+
+Examples:
+	clks: ccm@10027000{
+		compatible = "fsl,imx21-ccm";
+		reg = <0x10027000 0x800>;
+		#clock-cells = <1>;
+	};
+
+	uart1: serial@1000a000 {
+		compatible = "fsl,imx21-uart";
+		reg = <0x1000a000 0x1000>;
+		interrupts = <20>;
+		clocks = <&clks IMX21_CLK_UART1_IPG_GATE>,
+			 <&clks IMX21_CLK_PER1>;
+		clock-names = "ipg", "per";
+		status = "disabled";

Subject: ARM: mx6: Only check for 1.2GHz for mx6quad

It is only the mx6quad variant that can run up to 1.2GHz, so add the check
accordingly.

This avoids getting the following warning on a mx6solo:

failed to disable 1.2 GHz OPP

Subject: ARM: imx: mark .dt_compat as const

Otherwise GCC will mark the .init.rodata section R/W, which causes
a compile error once we add other real R/O data.

later.  Per ARM PL310 errata document, 588369 is fixed in r2p0 and
727915 is fixed in r3p1.  Neither is needed for i.MX6 or VF610.  So
let's drop them.

Subject: ARM: imx: imx6sx uses imx6q cpuidle code

Building a kernel for imx6sx but without imx6q support results in
this link error because of the missing cpuidle driver:

arch/arm/mach-imx/built-in.o: In function `imx6sx_init_late'::(.init.text+0xc228):
 undefined reference to `imx6q_cpuidle_init'

This patch adds a Makefile entry so we always build support for
the imx6q_cpuidle code when at least one of the 6sx or 6q variants
are enabled.

Subject: ARM: imx: build cpu_is_imx6sl function conditionally

imx6q_pm_enter calls imx6sl_set_wait_clk when run on an imx6sl
based machine. However if support for imx6sl is not enabled
at compile time, this prevents us from building the kernel and
we get this link error instead:

arch/arm/mach-imx/built-in.o: In function `imx6q_pm_enter':
:(.text+0x4b84): undefined reference to `imx6sl_set_wait_clk'

This makes the cpu_is_imx6sl function conditionally return false
if imx6sl is disabled at compile-time, which matches what the
older cpu_is_mx* macros did. We have similar inline functions for
the other imx6 variants, but so far I have not run into a case
where the extra #ifdef is necessary.

The board has no insufficient support to be fully functional and seems
has no users. This patch removes support for this board.
However, the support may be added in the future by using the devicetree.

Subject: ARM: i.MX: allow disabling supervisor protect via DT

The i.MX SoCs allow to setup fine grained access rights to peripherals on the
AIPS bus.
This is done via the Peripheral Access Register (PAR) in e.g. the i.MX21
or in later SoC versions the Off-Platform Peripheral Access Control Register
(OPACR), e.g. i.MX53.
Under certain circumstances this leads to problems in which bus masters are
not granted their access rights to peripherals.
To be able to disable these restrictions on DT platforms, add a helper function
that looks for AIPS nodes in the DT and disables them for every compatible node
it finds.
The compatible has to be declared in the mach-specific entry file, where this
helper function should then be called.

Subject: ARM: i.MX53: globally disable supervisor protect

Most peripherals on the i.MX53 have an
  Off-Platform Peripheral Access Control Register (OPACR)
in which the access rights (together with the MPROT registers) can be declared.
However, this does not seem to work for example for SSI1+SDMA, because the
supervisor bit is not set for the SDMA unit.
It does work for SSI2, the QSB for example uses SSI2 for its audio. But SSI2 only
works because it does NOT have an OPACR.

The right solution would be to fix the access rights for the SDMA, but the unit
responsible for this is the Central Security Unit (CSU), which of course is NOT
documented. So, until documentation for this is openly available, turn off the
supervisor protection because it cripples the hardware.

Subject: kbuild: allow to override Python command name

The specification of Python 3 is largely different from that of
Python 2.

For example, arch/ia64/scripts/unwcheck.py seems to be written
in Python 2, not compatible with Python 3.

It is not a good idea to invoke python scripts with the hard-coded
command name 'python'. The command 'python' could possibly be
Python 3 on some systems.
For that case, it is reasonable to allow to override the command name
by giving 'PYTHON=python2' from the command line.

The 'python' in arch/ia64/Makefile should be replaced with '$(PYTHON)'.

Subject: ARM: dts: imx6qdl-sabresd: Configure the ECSPI1 chip select pin

GPIO4_9 is used as ECSPI1 chip select and it needs to be configured as GPIO.

Configure the pin functionality explicitly in the dts file instead of relying
on the fact that it comes configured as GPIO from POR or from the bootloader.

Subject: ARM: dts: pfla02: Add ethernet phy supply regulator

The 2.5V VDD_ETH_IO voltage supplied by the DA9063 LDO4 is used
to power the KSZ9031 PHY DVDDH input and to pull the necessary
pins (including bootstrap pins) high.
It also powers the i.MX6 NVCC_RGMII and NVCC_ENET inputs.

Subject: ARM: dts: imx6: add support for Ka-Ro TX6 modules
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch adds support for the Ka-Ro electronics GmbH TX6 modules.
There are five distinct module types with either i.MX6Q or i.MX6DL and
LVDS or LCD display interface and one DTS file for a complete system
with an i.MX6DL based TX6 module and a baseboard mounted on the back
of a display (imx6dl-tx6dl-comtft.dts).

Subject: ARM: dts: imx6: remove wrong spdif rxtx2 clock

The rxtx2 clock of i.MX6 S/PDIF is currently set to "asrc" clock.
However, according to SoC documentation, rxtx2 is connected to
ASRC_EXT_CLK, a different external clock.

Testing on Cubox-i system seems to confirm that: when fsl_spdif is
forced to select rxtx2 as input clock, audio playback fails with an I/O
error.

Set rxtx2 to the dummy clock by default to prevent fsl_spdif from
selecting it.

Subject: ARM: dts: imx6: remove non-working spdif rxtx4 and rxtx6 clocks

The S/PDIF rxtx4 and rxtx6 clock inputs are "ESAI_HCKT" and "MLB clock",
respectively, according to the SoC documentation, and they are currently
mapped to clocks "esai" and "mlb".

However, they do not seem to actually work correctly. Testing on a
Cubox-i system with fsl_spdif driver forced to select one of those as
input will result in I/O errors on audio playback, which I believe means
missing clock signal.

Possibly the "ESAI_HCKT" and "MLB clock" refer to some other clocks
related to ESAI and MLB, or we are missing something else.

Since audio playback will not work if fsl_spdif selects these clocks
(which happens rarely), set the inputs do dummy clocks, at least for
now.

Subject: ARM: dts: imx: remove ssi fsl,mode for audio cards

The DAI mode is and should be configured by the sound card driver as
codec and ssi have to be in the right modes to communicate with each
other. It is possible to operate the ssi unit or the codec in master mode,
sometimes even on the same board in different configurations.

With the latest changes in the fsl-ssi driver, the 'fsl,mode' property
is only handled as a fallback property. If the sound card sets the DAI
mode correctly, this fallback configuration is dropped.

Subject: ARM: dts: mbimxsd25: cmo-qvga: Fix lcd regulator

The fixed-regulator's enable-active-high property
is needed to indicate that the GPIO regulator is
active high.

Before that the regulator state was inverted.

Subject: ARM: dts: imx6: add aristainetos board support

This patch add support for the imx6dl based aristainetos board
with following configuration:

CPU:   Freescale i.MX6DL rev1.1 at 792 MHz
DRAM:  1 GiB
NAND:  512 MiB
MMC:   FSL_SDHC: 0, FSL_SDHC: 1
SF: Detected N25Q128 with page size 256 Bytes, erase size 64 KiB, total 16 MiB

As this board can used with 2 different display types, the
differences between them are extracted into 2 DTS files, and
the common settings are collected in a common file.

Subject: ARM: dts: imx6sx: iomux-gpr syscon is compatible to imx6q

The imx6sx iomuxc-gpr syscon is compatible to imx6q, so let's add
compatible string 'fsl,imx6q-iomuxc-gpr' for imx6sx iomuxc-gpr syscon node.

This is necessary to enable SW workaround for ERR007265,
please refer to imx6_pm_common_init of arch/arm/mach-imx/pm-imx6.c
for detail.

When booting a board that does not have a keypad (such as imx6q-sabresd) the
following error is seen on boot:

imx-keypad 20b8000.kpp: OF: linux,keymap property not defined in /soc/aips-bus@02000000/kpp@020b8000
imx-keypad 20b8000.kpp: failed to build keymap
imx-keypad: probe of 20b8000.kpp failed with error -2

Let's disable the keypad functionality in the dtsi files and let each board dts
enable it when needed.

Subject: ARM: dts: imx: correct sdma compatbile for imx6sl and imx6sx

The SDMA on imx6sl and imx6sx is more compatible with imx6q one than
imx35.  Let's use "fsl,imx6q-sdma" instead of "fsl,imx35-sdma", so that
SDMA ROM script on imx6sl and imx6sx can work for audio driver just like
the case of imx6q.

Subject: ARM: i.MX27 clk: dts: Use clock defines in DTS files

Use clock definitions in i.MX27 DTS files.
Additional changes included in this patch (imx27.dtsi):
- Fix IPG clock for UART6.
- Use EMI_AHB_GATE clock for WEIM.
- Added GPIO_IPG_GATE clock for GPIO nodes. Currently this clock is
  not used by the driver, but it can be added in the future.

Subject: ARM: imx6: Align ssi nodes between mx6 variants

Since commit 98ea6ad2edd2 (ARM: dts: imx6: use imx51-ssi) the mx6 ssi is
compatible with imx51, so align all the mx6 variant ssi compatible strings as:

compatible = "fsl,<imx6-soc>-ssi", "fsl,imx51-ssi";

Subject: ARM: dts: imx53: correct clock-names of SATA node

Per the binding doc imx-sata.txt, the first entry of clock-names should
be "sata" than anything else.  Correct it for imx53 SATA node.

It works for now only because SATA driver gets clock by index so far.

Subject: ARM: dts: Restructure imx6qdl-wandboard.dtsi for new rev C1 board.

The rev C1 Wandboard uses the Broadcom 4330 for WiFi and Bluetooth instead of
the 4329.  This changes the PADS assigned for the control lines.  Another
side effect of the change is that on the rev C1 board, usdhc driver can't
detect the chip presence correctly so usdhc2 now needs its 'non-removeable'
property removed.

So that rev B1 and earlier can continue to work, this patch splits the
board-specific definitions from imx6qdl-wandboard.dtsi into
imx6qdl-wandboard-revb1.dtsi and imx6qdl-wandboard-revc1.dtsi.  The new files
include the original base imx6qdl-wandboard.dtsi which retains the common
definitions.

The existing imx6dl-wandboard.dts includes imx6qdl-wandboard-revc1.dtsi and
imx6dl-wandboard-revb1.dts (new) includes imx6qdl-wandboard-revb1.dtsi.
This makes the rev C1 board the new default.  The same pattern is used for
imx6q-wandboard.dts.

So, from U-Boot on a WB-Quad you use imxq-wandboard-revb1.dtb for the older B1
board and imxq-wandboard.dtb for the current rev C1 board.

Subject: ARM: dts: imx6: RIoTboard explicitly define pad settings

Instead of relying on defaults or bootloader settings, explicitly define
all pad settings.

This resolves reported issues of no analogue audio output.

From 18e8499b22f5ea21449f2ea8730e06982c24cfc0 Mon Sep 17 00:00:00 2001
From: Marek Vasut <marex@denx.de>
Date: Wed, 25 Jun 2014 20:48:32 +0200
Subject: ARM: dts: mx5: Split M53EVK into SoM and EVK parts

This patch splits the M53EVK device tree file into a common SoM
part and an EVK part. This is needed to make it easier for users
of the SoM to put it into different, non-reference baseboard.

Subject: ARM: dts: add initial Rex Pro board support

Add initial Rex Pro i.mx6q board support. Ethernet, UART, USB, I2C, SPI, HDMI,
Audio, and SDHC cards are working.  Currently no mainline u-boot, so boot with
cat zImage imx6q-rex-pro.dtb > zImage.dtb, then using mkimage create uImage

Subject: metag: cachepart: Fix failure check

[linux-3.16-rc5/arch/metag/kernel/cachepart.c:102]: (style) Checking if
unsigned variable 'thread_cache_size' is less than zero.

Source code is

        if (thread_cache_size < 0)
            pr_emerg("Can't read %s cache size\n",
                 cache_type ? "DCACHE" : "ICACHE");

but

    unsigned int thread_cache_size;

Function get_thread_cache_size returns an error code
as (unsigned int) -1.

Change get_thread_cache_size() to return signed int, and its result is
stored into signed int variable.

     preempt_disable();

The problem here is recursive header inclusion which could be avoided by
removing linux/reboot.h from mach/iop13xxx.h.
linux/reboot.h in include/mach/iop13xx.h is needed only for enum reboot_mode,
so header it could be replaced with a enum declaration.

Whatever patch "ARM: 8078/1: get rid of hardcoded assumptions about kernel stack size"
does, I think it's good to avoid unnecessary header inclusion here in any case.

Subject: ARM: 8081/1: MCPM: provide infrastructure to allow for MCPM loopback

The kernel already has the responsibility to handle resources such as the

CCI when hotplugging CPUs, during the booting of secondary CPUs, and when
resuming from suspend/idle.  It would be more coherent and less confusing
if the CCI for the boot CPU (or cluster)  was also initialized by the
kernel rather than expecting the firmware/bootloader to do it and only in
that case. After all, the kernel has all the necessary code already and
the bootloader shouldn't have to care at all.

The CCI may be turned on only when the cache is off. Leveraging the CPU
suspend code to loop back through the low-level MCPM entry point is all
that is needed to properly turn on the CCI from the kernel by using the
same code as during secondary boot.

Let's provide a generic MCPM loopback function that can be invoked by
backend initialization code to set things (CCI or similar) on the boot
CPU just as it is done for the other CPUs.

Subject: ARM: 8083/1: exynos: activate the CCI on boot CPU/cluster using the
 MCPM loopback

The Chromebook firmware doesn't enable the CCI for the boot cpu, and
arguably it shouldn't have to either. Let's have the kernel handle the

CCI on its own for the boot CPU the same way it does it for secondary CPUs
by using the MCPM loopback.

This allows to boot all 8 cores on exynos5420-peach-pit,
exynos5800-peach-pi and ARM Chromebook 2.

Subject: ARM: make it easier to check the CPU part number correctly

Ensure that platform maintainers check the CPU part number in the right
manner: the CPU part number is meaningless without also checking the
CPU implement(e|o)r (choose your preferred spelling!)  Provide an
interface which returns both the implementer and part number together,
and update the definitions to include the implementer.

Mark the old function as being deprecated... indeed, using the old
function with the definitions will now always evaluate as false, so
people must update their un-merged code to the new function.  While
this could be avoided by adding new definitions, we'd also have to
create new names for them which would be awkward.

From 6ebbf2ce437b33022d30badd49dc94d33ecfa498 Mon Sep 17 00:00:00 2001
From: Russell King <rmk+kernel@arm.linux.org.uk>
Date: Mon, 30 Jun 2014 16:29:12 +0100
Subject: ARM: convert all "mov.* pc, reg" to "bx reg" for ARMv6+
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ARMv6 and greater introduced a new instruction ("bx") which can be used
to return from function calls.  Recent CPUs perform better when the
"bx lr" instruction is used rather than the "mov pc, lr" instruction,
and this sequence is strongly recommended to be used by the ARM
architecture manual (section A.4.1.1).

We provide a new macro "ret" with all its variants for the condition
code which will resolve to the appropriate instruction.

Rather than doing this piecemeal, and miss some instances, change all
the "mov pc" instances to use the new macro, with the exception of
the "movs" instruction and the kprobes code.  This allows us to detect
the "mov pc, lr" case and fix it up - and also gives us the possibility
of deploying this for other registers depending on the CPU selection.

Subject: ARM: alignment: save last kernel aligned fault location

Save and report (via the procfs file) the last kernel unaligned fault
location.  This allows us to trivially inspect where the last fault
happened for cases which we don't expect to occur.

Since we expect the kernel to generate misalignment faults (due to
the networking layer), even when warnings are enabled, we don't log
them for the kernel.

Subject: ARM: 8079/1: zImage: identify kernel endianness

With patch #8067/1 ("zImage: ensure header in LE format for BE8 kernels")
applied, it is no longer possible to determine the endianness of a compiled
kernel image.  This normally shouldn't matter to the boot environment,
except for those cases where the selection of a ramdisk or root filesystem
with a matching endianness has to be automated.

Let's add a flag to the zImage header indicating the actual endianness.
Four bytes from offset 0x30 can be interpreted as follows:

	04 03 02 01	big endian kernel

	01 02 03 04	little endian kernel

Anything else should be interpreted as "unknown", in which case it is
most likely that patch #8067/1 was not applied either and the zImage
magic number at offset 0x24 could be used instead to determine
endianness. No zImage before this patch ever produced 0x01020304 nor
0x04030201 at offset 0x30 so there is no confusion possible.

Subject: ARM: 8070/1: Introduce arm_get_current_stack_frame()

Currently there are numerous places where "struct pt_regs" are used to
populate "struct stackframe", however all of those location do not
consider the situation where the kernel might be compiled in THUMB2
mode, in which case the framepointer member of pt_regs become ARM_r7
instead of ARM_fp (r11). Document this idiosyncracy in the
definition of "struct stackframe"

The easiest solution is to introduce a new function (in the spirit of
https://groups.google.com/forum/#!topic/linux.kernel/dA2YuUcSpZ4)
which would hide the complexity of initializing the stackframe struct
from pt_regs.

Also implement a macro frame_pointer(regs) that would return the correct
register so that we can use it in cases where we just require the frame
pointer and not a whole struct stackframe

Commit 78d7530ac3 ("ARM: Clean up linker script using new linker script
macros.") modified the arm kernel linker script to use the STABS_DEBUG
macro, but left a .comment section definition. As STABS_DEBUG defines
the .comment section in an identical way, the second section definition
is redundant and can be removed.

This patch removes the redundant .comment section definition.

Subject: ARM: 8089/1: cpu_pj4b_suspend_size should base on cpu_v7_suspend_size

Since pj4b suspend/resume routines are implemented based on generic
ARMv7 ones, instead of hard-coding cpu_pj4b_suspend_size, we should have
it be cpu_v7_suspend_size plus pj4b specific bytes.  Otherwise, if
cpu_v7_suspend_size gets updated alone, the pj4b suspend/resume will
likely be broken.

While at it, fix the comments in cpu_pj4b_do_resume, as we're restoring
CP15 registers rather than saving in there.

Subject: ARM: 8091/2: add get_user() support for 8 byte types

Recent contributions, including to DRM and binder, introduce 64-bit
values in their interfaces. A common motivation for this is to allow
the same ABI for 32- and 64-bit userspaces (and therefore also a shared
ABI for 32/64 hybrid userspaces). Anyhow, the developers would like to
avoid gotchas like having to use copy_from_user().

This feature is already implemented on x86-32 and the majority of other
32-bit architectures. The current list of get_user_8 hold out
architectures are: arm, avr32, blackfin, m32r, metag, microblaze,
mn10300, sh.

Credit:

    My name sits rather uneasily at the top of this patch. The v1 and
    v2 versions of the patch were written by Rob Clark and to produce v4
    I mostly copied code from Russell King and H. Peter Anvin. However I
    have mangled the patch sufficiently that *blame* is rightfully mine
    even if credit should more widely shared.

Changelog:

v5: updated to use the ret macro (requested by Russell King)
v4: remove an inlined add on big endian systems (spotted by Russell King),
    used __ARMEB__ rather than BIG_ENDIAN (to match rest of file),
    cleared r3 on EFAULT during __get_user_8.
v3: fix a couple of checkpatch issues
v2: pass correct size to check_uaccess, and better handling of narrowing
    double word read with __get_user_xb() (Russell King's suggestion)
v1: original

Subject: ARM: 8103/1: save/restore Cortex-A9 CP15 registers on suspend/resume

The CP15 diagnostic register holds ARM errata bits on Cortex-A9, so it
needs to be saved/restored on suspend/resume.  Otherwise, the
effectiveness of errata workaround gets lost together with diagnostic
register bit across suspend/resume cycle.  And the CP15 power control
register of Cortex-A9 shares the same problem.

The patch adds a couple of Cortex-A9 specific suspend/resume functions
to save/restore these two Cortex-A9 CP15 registers across the
suspend/resume cycle.

Subject: ARM: SWP emulation: always enable when SMP is enabled

SWP is deprecated in ARMv6 and ARMv7 CPUs, but more importantly, when
running on a SMP system, SWP doesn't guarantee atomicity.  This means
it can't really be used (by userspace) for locking purposes in a SMP
environment.

Currently, many configurations leave the SWP emulation disabled, which
means we never know if userspace executes this instruction on ARMv7
hardware.  Rectify this by enabling SWP emulation for ARMv7 with SMP
(where we can trap the instruction.)

Subject: ARM: hwcap: disable HWCAP_SWP if the CPU advertises it has exclusives

When the CPU has support for the byte and word exclusive operations,
userspace should use them in preference to the SWP instructions.
Detect the presence of these instructions by reading the ISAR CPU ID
registers and adjust the ELF HWCAP mask appropriately.

Note that ARM1136 < r1p0 has no ISAR4, so this is explicitly detected
and the test disabled, leaving the current situation where HWCAP_SWP
is set.

This patch cleans a arm-pmu node up for exynos4. Only exynos4412 series
boards have four pmu interrupts. Rest of exynos4 boards, except 4412, have only
two pmu interrupts. Thus, we can define two interrupts in the
exynos4.dtsi and extends the interrupts only exynos4412.dtsi.

Subject: ARM: EXYNOS: populate suspend and powered_up callbacks for mcpm

In order to support cpuidle through mcpm, suspend and powered-up
callbacks are required in mcpm platform code.
Hence populate the same callbacks.

Subject: ARM: dts: Add cros_ec to exynos5420-peach-pit and exynos5800-peach-pi

This adds cros_ec to exynos5420-peach-pit and exynos5800-peach-pi,
including:
* The keyboard
* The i2c tunnel
* The tps65090 under the i2c tunnel
* The battery under the i2c tunnel

To add extra motivation, it should be noted that tps65090 is one of
the things needed to get display-related FETs turned on for pit and
pi.

From: Kees Cook <keescook@chromium.org>
Date: Wed, 25 Jun 2014 16:08:24 -0700
Subject: seccomp: add "seccomp" syscall

This adds the new "seccomp" syscall with both an "operation" and "flags"
parameter for future expansion. The third argument is a pointer value,
used with the SECCOMP_SET_MODE_FILTER operation. Currently, flags must
be 0. This is functionally equivalent to prctl(PR_SET_SECCOMP, ...).

In addition to the TSYNC flag later in this patch series, there is a
non-zero chance that this syscall could be used for configuring a fixed
argument area for seccomp-tracer-aware processes to pass syscall arguments
in the future. Hence, the use of "seccomp" not simply "seccomp_add_filter"
for this syscall. Additionally, this syscall uses operation, flags,
and user pointer for arguments because strictly passing arguments via
a user pointer would mean seccomp itself would be unable to trivially
filter the seccomp syscall itself.

Subject: ARM: SAMSUNG: Remove legacy clock code

Since S5PV210 now has a complete clock driver using Common Clock
Framework, there is no reason to keep the old code. Remove it together
with the whole legacy Samsung-specific clock framework which no longer
has any users.

From 0a90d4d62c71e27cedebf938d7c37db543b93e78 Mon Sep 17 00:00:00 2001
From: Tomasz Figa <t.figa@samsung.com>
Date: Wed, 2 Jul 2014 19:37:45 +0200
Subject: ARM: S5PV210: Untie PM support from legacy code

This patch makes S5PV210 not rely on legacy suspend helpers in
plat-samsung and implements platform suspend logic locally, similarly to
Exynos.

From d78c16ccde96eddf42942c093b241b5e5135b777 Mon Sep 17 00:00:00 2001
From: Tomasz Figa <t.figa@samsung.com>

Subject: ARM: SAMSUNG: Remove remaining legacy code

After refactoring suspend/resume, which was last part with dependencies
on legacy code, all Kconfig symbols related to Samsung ATAGS support can
be deselected and more unused code removed. This includes most of s5p-*
code as well, as s5pv210 was their last user.

Subject: ARM: EXYNOS: Fix build breakge with PM_SLEEP=n

Fix building of exynos_defconfig with disabled PM_SLEEP:
CONFIG_PM_SLEEP=n
CONFIG_PM_SLEEP_SMP=n
CONFIG_SUSPEND=n
by moving functions for power up/down of CPU and cluster to platsmp.c

The build error messages:

With the addition of ARM64 that does not have a traditional BIOS to

it either, it is EFI/UEFI based system) to do the traditional BIOS
scanning for tables.

Subject: ACPI: Don't use acpi_lapic in ACPI core code

Now ARM64 support is being added to ACPI so architecture specific
values can not be used in core ACPI code.

Following on the patch "ACPI / processor: Check if LAPIC is present
during initialization" which uses acpi_lapic in acpi_processor.c,
on ARM64 platform, GIC is used instead of local APIC, so acpi_lapic
is not a suitable value for ARM64.

What is actually important at this point is if there is/are CPU
entry/entries (Local APIC/SAPIC, GICC) in MADT, so introduce
acpi_has_cpu_in_madt() to be arch specific and generic.

From 46ba51ea8f8639da32c55744b35479fdfb4e7232 Mon Sep 17 00:00:00 2001
From: Hanjun Guo <hanjun.guo@linaro.org>

Subject: ACPI / processor: Introduce ARCH_MIGHT_HAVE_ACPI_PDC

The use of _PDC is deprecated in ACPI 3.0 in favor of _OSC,
as ARM platform is supported only in ACPI 5.0 or higher version,
_PDC will not be used in ARM platform, so make Make _PDC only for
platforms with Intel CPUs.

Introduce ARCH_MIGHT_HAVE_ACPI_PDC and move _PDC related code in
ACPI processor driver into a single file processor_pdc.c, make x86
and ia64 select it when ACPI is enabled.

This patch also use pr_* to replace printk to fix the checkpatch
warning and factor acpi_processor_alloc_pdc() a little bit to
avoid duplicate pr_err() code.

Subject: sparc: Add support for seek and shorter read to /dev/mdesc

/dev/mdesc on Linux does not support reading arbitrary number
of bytes and seeking while /dev/mdesc on Solaris does. This
causes tools that work on Solaris to break on Linux. This patch
adds these two capabilities to /dev/mdesc.

Subject: sparc64: update IO access functions in PeeCeeI

The PeeCeeI.c code used in*() + out*() for IO access.
But these are in little endian and the native (big) endian
result was required which resulted in some bit-shifting.
Shift the code over to use the __raw_*() variants all over.

This simplifies the code as we can drop the calls
to le16_to_cpu() and le32_to_cpu().
And it should be a little faster too.

With this change we now uses the same type of IO access functions
in all of the file.

Subject: sparc64: remove macro indirection in io_64.h

Most likely for historical reasons io_64.h used an
extra layer of macro indirections.

Fix it so we no longer use these indirections.
In the process we loose a cast to the addr argument for in*()/out*()
but all known affected users has already been fixed so
no warnings are triggered.

For each of the IO functions add a proper define like this:

    #define inb inb

This is done to make the code compatible with the way these
functions are defined in asm-generic/io.h with the objective
to later introduce the generic io.h for sparc64.

Subject: sparc64: reorder functions in io_64.h

Reorder functions so __raw_{read,write}* functions comes first,
followed by {read,write}*

Update comments for the two blocks of functions.

Subject: sparc64: avoid code duplication in io_64.h

Several of the small IO functions ended up having the same implementation.
Use __raw_{read,write}* + {read,write}* as base for the others.

Continue to use static inline functions to get full type check.
The size of vmlinux for a defconfig build was the same when
using static inline and macros for the functions - so there
was no size win when using macros.

This was tested with gcc 4.8.2 + binutils 2.24.
For such simple constructs I assume older gcc's will
do the same job.

Subject: ARM: OMAP2+: DMA: remove requirement of irq for platform-dma driver

we have currently 2 DMA drivers that try to co-exist.
drivers/dma/omap-dma.c which registers it's own IRQ and is device tree
aware and uses arch/arm/plat-omap/dma.c instance created by
arch/arm/mach-omap2/dma.c to maintain channel usage (omap_request_dma).

Currently both try to register interrupts and mach-omap2/plat-omap dma.c
attempts to use the IRQ number registered by hwmod to register it's own
interrupt handler.

Now, there is no reasonable way of static allocating DMA irq in GIC
SPI when we use crossbar. However, since the dma_chan structure is
freed as a result of IRQ not being present due to devm allocation,
maintaining information of channel by platform code fails at a later
point in time when that region of memory is reused.

So, if hwmod does not indicate an IRQ number, then, assume that
dma-engine will take care of the interrupt handling.

Subject: s390/qdio: add helpers to manage qdio buffers

Users of qdio buffers employ different strategies to manage these
buffers. The qeth driver uses huge contiguous buffers which leads
to high order allocations with all their downsides.

This patch provides helpers to allocate, free, and reset arrays of
qdio buffers using non contiguous pages.

Subject: s390/pci: introduce lazy IOTLB flushing for DMA unmap

This changes the default IOTLB flushing method to lazy flushing, which
means that there will be no direct flush after each DMA unmap operation.
Instead, the iommu bitmap pointer will be adjusted after unmap, so that
no DMA address will be re-used until after an iommu bitmap wrap-around.
The only IOTLB flush will then happen after each wrap-around.

A new kernel parameter "s390_iommu=" is also introduced, to allow changing
the flushing behaviour to the old strict method.

Subject: arm: add basic support for Mediatek MT6589 boards

This adds a generic devicetree board file and a dtsi for boards
based on MT6589 SoCs from Mediatek.

Apart from the generic parts (gic, clocks) the only component
currently supported are the timers.

Subject: PM / OPP: Remove ARCH_HAS_OPP

Since the OPP layer is a kernel library which has been converted to be
directly selectable by its callers rather than user selectable and
requiring architectures to enable it explicitly the ARCH_HAS_OPP symbol
has become redundant and can be removed. Do so.

Subject: ACPICA: Linux: Add support to exclude <asm/acenv.h> inclusion.

The forthcoming patch will make <acpi/acpi.h> to be visible to all kernel
source code. Thus for the architectures that do not support ACPI and
haven't implemented <asm/acenv.h>, we need to make it excluded.

Subject: ARM: EXYNOS: Support cluster power off on exynos5420/5800

Turning off a cluster when all 4 cores of the cluster are powered off
saves power significantly. Powering off the A15 L2 alone gives around
100mW in savings. Add support for powering off the A15/A7 clusters on
exynos5420/5800.

The patch enables specific register bits which ensure that:
   - cluster L2 will be turned on before the first man is powered up.
   - last man will be turned off before the cluster L2 is turned off.
   - core is powered down before powering it up.

Remove the exynos_cluster_power_control function completely as we can
rely on the above mentioned bits rather than polling the cluster power
status register.

Subject: ARM: EXYNOS: Refactored code for using PMU address via DT

Under "arm/mach-exynos" many files are using PMU register offsets.
Since we have added support for accessing PMU base address via DT,
now we can remove PMU mapping from exynosX_iodesc. Let's convert
all these access using iomapped address.
This will help us in removing static mapping of PMU base address
as well as help in reducing dependency over machine header files.
Thus helping for migration of PMU implementation from machine to
driver folder which can be reused for ARM64 based SoC.

Also as we have removed static mappings from "regs-pmu.h" it does
not need map.h anymore. But "platsmp.c" needed this and till now it
got included indirectly. So lets move header inclusion of
"mach/map.h" from "regs-pmu.h" to "platsmp.c".

Subject: ARM: EXYNOS: Move cpufreq and cpuidle device registration to
 init_machine

As exynos_cpuidle_init() and exynos_cpufreq_init() functions have just
one line of code for registering platform devices. So we can move them
to exynos_dt_machine_init() and remove exynos_cpuidle_init() and
exynos_cpufreq_init(). This will help in reducing lines of code in
exynos.c, making it more clean.

Subject: ARC: [SMP] unify cpu private IRQ requests (TIMER/IPI)

The current cpu-private IRQ registration is ugly as it requires need to
expose arch_unmask_irq() outside of intc code.
So switch to percpu IRQ APIs:
  -request_percpu_irq [boot core]
  -enable_percpu_irq  [all cores]

Encapsulated in helper arc_request_percpu_irq()

Subject: ARC: [intc] don't mask all IRQ by default

Hardware keeps them enabled on reset, and Linux needs to keep status quo.
Any spurious interrupts will be reported/blocked by genirq.

This helps remove a SMP IRQ quirk (next commit), where a peripheral IRQ
is hard wired to core0, and request_irq()->unmask() happens on core1,
keeping the IRQ masked on core0, needing an explicit unmask.

Subject: ARC: move common ops for line/full cache into helpers

INV cmd for dcache provides 2 modes discard or wback-before-discard.
One is default and other needs to be set, if so desired. This is common
for line-op/entire-cache-op. So refactor them out into a helper

Doesn't affect generated code but paves way for any common
micro-optimization.

Subject: ARM: rockchip: select ARMv7 compiler flags for platsmp.o

When compiling for multiplatform for both ARMv6 and ARMv7, the default
compiler flags are for ARMv6, and the following cpu-hotplug change will
fail with:
 /tmp/ccSFxfmI.s:68: Error: selected processor does not support ARM mode `isb '
 /tmp/ccSFxfmI.s:74: Error: selected processor does not support ARM mode `isb '
 /tmp/ccSFxfmI.s:75: Error: selected processor does not support ARM mode `dsb '

Fix this in a similar manner as in commit 9f0affcf3e21 "ARM: mvebu: Fix pmsu
compilation when ARMv6 is selected", by specifying ARMv7 flags for platsmp.o.

Subject: ARM: mvebu: Add missing MDIO clock in Armada 375

In Armada 375 SoCs, the MDIO is handled by a separate orion-mdio driver,
despite the register is contained within the "LMS" block of the network
controller.

Therefore we need to add the clock to the MDIO devicetree to prevent the
controller from being accesed with its clock gated. This is needed, for
instance, to be able to load the MDIO driver before the network driver.

Subject: video: fix up versatile CLCD helper move

commit 11c32d7b6274cb0f ("video: move Versatile CLCD helpers")
moved files out of the plat-versatile directory but in the process
got a few of the dependencies wrong:

- If CONFIG_FB is not set, the file no longer gets built, resulting
  in a link error
- If CONFIG_FB or CONFIG_FB_ARMCLCD are disabled, we also get a
  Kconfig warning for incorrect dependencies due to the symbol
  being 'select'ed from the platform Kconfig.
- When the file is not built, we also get a link error for missing
  symbols.

This patch should fix all three, by removing the 'select' statements,
changing the Kconfig description of the symbol to be enabled in
exactly the right configurations, and adding inline stub functions
for the case when the framebuffer driver is disabled.

Subject: tile: Convert VDSO timekeeping to the precise mechanism

The code was only halfarsed converted to the new VSDO update mechanism
and still uses the inaccurate base value which lacks the fractional
part of xtime_nsec. Fix it up.

Subject: ktime: Kill non-scalar ktime_t implementation for 2038

The non-scalar ktime_t implementation is basically a timespec
which has to be changed to support dates past 2038 on 32bit
systems.

This patch removes the non-scalar ktime_t implementation, forcing
the scalar s64 nanosecond version on all architectures.

This may have additional performance overhead on some 32bit
systems when converting between ktime_t and timespec structures,
however the majority of 32bit systems (arm and i386) were already
using scalar ktime_t, so no performance regressions will be seen
on those platforms.

On affected platforms, I'm open to finding optimizations, including
avoiding converting to timespecs where possible.

[ tglx: We can now cleanup the ktime_t.tv64 mess, but thats a
  different issue and we can throw a coccinelle script at it ]

Subject: ARM: dts: Fix wrong compatible string for Exynos3250 ADC

This patchset fix wrong compatible string for Exynos3250 ADC. Exynos3250 SoC
need to control only special clock for ADC. Exynos SoC except for Exynos3250
has not included special clock for ADC. The exynos ADC driver can control
special clock if compatible string is 'exynos3250-adc-v2'.

Subject: clocksource: Move cycle_last validation to core code

The only user of the cycle_last validation is the x86 TSC. In order to
provide NMI safe accessor functions for clock monotonic and
monotonic_raw we need to do that in the core.

We can't do the TSC specific

    if (now < cycle_last)
       	    now = cycle_last;

for the other wrapping around clocksources, but TSC has
CLOCKSOURCE_MASK(64) which actually does not mask out anything so if
now is less than cycle_last the subtraction will give a negative
result. So we can check for that in clocksource_delta() and return 0
for that case.

Implement and enable it for x86

From d28ede83791defee9a81e558540699dc46dbbe13 Mon Sep 17 00:00:00 2001
From: Thomas Gleixner <tglx@linutronix.de>
Date: Wed, 16 Jul 2014 21:05:16 +0000
Subject: timekeeping: Create struct tk_read_base and use it in struct
 timekeeper

The members of the new struct are the required ones for the new NMI
safe accessor to clcok monotonic. In order to reuse the existing
timekeeping code and to make the update of the fast NMI safe
timekeepers a simple memcpy use the struct for the timekeeper as well
and convert all users.

Subject: of: Move dynamic node fixups out of powerpc and into common code

PowerPC does an odd thing with dynamic nodes. It uses a notifier to
catch new node additions and set some of the values like name and type.
This makes no sense since that same code can be put directly into
of_attach_node(). Besides, all dynamic node users need this, not just
powerpc. Fix this problem by moving the logic out of arch/powerpc and
into drivers/of/dynamic.c.

It is also important to remove this notifier because we want to move the
firing of notifiers from before the tree is modified to after so that
the receiver gets a consistent view of the tree, but that is
incompatible with notifiers that modify the node.

From 259092a35c7e11f1d4616b0f5b3ba7b851fe4fa6 Mon Sep 17 00:00:00 2001
From: Grant Likely <grant.likely@linaro.org>
Date: Wed, 16 Jul 2014 12:48:23 -0600
Subject: of: Reorder device tree changes and notifiers

Currently, devicetree reconfig notifiers get emitted before the change
is applied to the tree, but that behaviour is problematic if the
receiver wants the determine the new state of the tree. The current
users don't care, but the changeset code to follow will be making
multiple changes at once. Reorder notifiers to get emitted after the
change has been applied to the tree so that callbacks see the new tree
state.

At the same time, fixup the existing callbacks to expect the new order.
There are a few callbacks that compare the old and new values of a
changed property. Put both property pointers into the of_prop_reconfig
structure.

The current notifiers also allow the notifier callback to fail and
cancel the change to the tree, but that feature isn't actually used.
It really isn't valid to ignore a tree modification provided by firmware
anyway, so remove the ability to cancel a change to the tree.

From d2168146c222d607bf4baeaaaa990f39411d1567 Mon Sep 17 00:00:00 2001
From: Pawel Moll <pawel.moll@arm.com>
Date: Wed, 23 Jul 2014 18:07:18 +0100
Subject: platform: Remove most references to platform_bus device

A number of board files in arch/arm and arch/unicore32
explicitly reference platform_bus device as a parent
for new platform devices.

This is unnecessary, as platform device API guarantees
that devices with NULL parent are going to by adopted
by the mentioned "root" device.

This patch removes or replaces with NULL such references.

Subject: ARM: mvebu: split again armada_370_xp_pmsu_idle_enter() in PMSU code

do_armada_370_xp_cpu_suspend() and armada_370_xp_pmsu_idle_prepare(),
have been merged into a single function called
armada_370_xp_pmsu_idle_enter() by the commit "bbb92284b6c8 ARM:
mvebu: slightly refactor/rename PMSU idle related functions", in
prepare for the introduction of the CPU hotplug support for Armada XP.

But for cpuidle the prepare function will be common to all the mvebu
SoCs that use the PMSU, while the suspend function will be specific to
each SoC. Keeping the prepare function separate will help reducing
code duplication while new SoC support is added.

Subject: ARM: mvebu: add a common function for the boot address work around

On some of the mvebu SoCs and due to internal BootROM issue, the CPU
initial jump code must be placed in the SRAM memory of the SoC. In
order to achieve this, we have to unmap the BootROM and at some
specific location where the BootROM was placed, create a dedicated
MBus window for the SRAM. This SRAM is initialized with a few
instructions of code that allows to jump to the real secondary CPU
boot address. The SRAM used is the Crypto engine one.

This work around is currently needed for booting SMP on Armada 375 Z1
and will be needed for cpuidle support on Armada 370. Instead of
duplicating the same code, this commit introduces a common function to
handle it: mvebu_setup_boot_addr_wa().

Subject: ARM: mvebu: use the common function for Armada 375 SMP workaround

Use the common function mvebu_setup_boot_addr_wa() introduced in the
commit "ARM: mvebu: Add a common function for the boot address work
around" instead of the dedicated version for Armada 375.

This commit also moves the workaround in the system-controller
module. Indeed the workaround on 375 is really related to setting the
boot address which is done by the system controller.

As a bonus we no longer use an harcoded value to access the register
storing the boot address.

Subject: ARM: mvebu: rename the armada_370_xp symbols to mvebu_v7 in pmsu.c

Most of the function related to the PMSU are not specific to the
Armada 370 or Armada XP SoCs. They can also be used for most of the
other mvebu ARMv7 SoCs, and will actually be used to support cpuidle
on Armada 38x.

Subject: ARM: mvebu: use a local variable to store the resume address

The resume address used by the cpuidle code will not always be the
same depending on the SoC. Using a local variable to store the resume
address allows to keep the same function for the PM notifier but with
a different address. This address will be set during the
initialization of the cpuidle logic in pmsu.c.

Subject: ARM: mvebu: make the snoop disabling optional in
 mvebu_v7_pmsu_idle_prepare()

On some mvebu v7 SoCs (the ones using a Cortex-A9 core and not a PJ4B
core), the snoop disabling feature does not exist as the hardware
coherency is handled in a different way. Therefore, in preparation to
the introduction of the cpuidle support for those SoCs, this commit
modifies the mvebu_v7_psmu_idle_prepare() function to take several
flags, which allow to decide whether snooping should be disabled, and
whether we should use the deep idle mode or not.

Subject: ARM: mvebu: export the SCU address

The SCU address will be needed in other files than board-v7.c,
especially in pmsu.c for cpuidle related activities. So this patch
adds a function that allows to retrieve the virtual address at which
the SCU has been mapped.

Subject: cpuidle: mvebu: rename the driver from armada-370-xp to mvebu-v7

This driver will be able to manage the cpuidle for more SoCs than just
Armada 370 and XP. It will also support Armada 38x and potentially
other SoC of the Marvell Armada EBU family. To take this into account,
this patch renames the driver and its symbols.

It also changes the driver name from cpuidle-armada-370-xp to
cpuidle-armada-xp, because separate platform drivers will be
registered for the other SoC types. This change must be done
simultaneously in the cpuidle driver and in the PMSU code in order to
remain bisectable.

Subject: ARM: mvebu: add cpuidle support for Armada 370

This commit introduces the cpuidle support for Armada 370. The main
difference compared to the already supported Armada XP is that the
Armada 370 has an issue caused by "a slow exit process from the deep
idle state due to heavy L1/L2 cache cleanup operations performed by
the BootROM software" (cf errata GL-BootROM-10).

To work around this issue, we replace the restart code of the BootROM
by some custom code located in an internal SRAM. For this purpose, we
use the common function mvebu_boot_addr_wa() introduced in the commit
"ARM: mvebu: Add a common function for the boot address work around".

The message in case of failure to suspend the system was switched from
the warn level to the debug level. Indeed due to the "slow exit
process from the deep idle state" in Armada 370, this situation
happens quite often. Using the debug level avoids spamming the kernel
logs, but still allows to enable it if needed.

Subject: ARM: mvebu: add cpuidle support for Armada 38x

Unlike the Armada XP and the Armada 370, this SoC uses a Cortex A9
core. Consequently, the procedure to enter the idle state is
different: interaction with the SCU, not disabling snooping, etc.

Subject: ARM: 8108/1: mm: Introduce {pte,pmd}_isset and {pte,pmd}_isclear

Long descriptors on ARM are 64 bits, and some pte functions such as
pte_dirty return a bitwise-and of a flag with the pte value. If the
flag to be tested resides in the upper 32 bits of the pte, then we run
into the danger of the result being dropped if downcast.

For example:
	gather_stats(page, md, pte_dirty(*pte), 1);
where pte_dirty(*pte) is downcast to an int.

This patch introduces a new macro pte_isset which performs the bitwise
and, then performs a double logical invert (where needed) to ensure
predictable downcasting. The logical inverse pte_isclear is also
introduced.

Equivalent pmd functions for Transparent HugePages have also been
added.

From: Steven Capper <steve.capper@linaro.org>
Date: Fri, 18 Jul 2014 16:16:15 +0100
Subject: ARM: 8109/1: mm: Modify pte_write and pmd_write logic for LPAE

For LPAE, we have the following means for encoding writable or dirty
ptes:
                              L_PTE_DIRTY       L_PTE_RDONLY
    !pte_dirty && !pte_write        0               1
    !pte_dirty && pte_write         0               1
    pte_dirty && !pte_write         1               1
    pte_dirty && pte_write          1               0

So we can't distinguish between writeable clean ptes and read only
ptes. This can cause problems with ptes being incorrectly flagged as
read only when they are writeable but not dirty.

This patch renumbers L_PTE_RDONLY from AP[2] to a software bit #58,
and adds additional logic to set AP[2] whenever the pte is read only
or not dirty. That way we can distinguish between clean writeable ptes
and read only ptes.

HugeTLB pages will use this new logic automatically.

We need to add some logic to Transparent HugePages to ensure that they
correctly interpret the revised pgprot permissions (L_PTE_RDONLY has
moved and no longer matches PMD_SECT_AP2). In the process of revising
THP, the names of the PMD software bits have been prefixed with L_ to
make them easier to distinguish from their hardware bit counterparts.

Subject: ARM: mvebu: fix build without platforms selected

When building a multiplatform kernel that enables 'ARCH_MVEBU' but
none of the individual options under it, we get this link error:

arch/arm/mach-mvebu/built-in.o: In function `mvebu_armada375_smp_wa_init':
:(.text+0x190): undefined reference to `mvebu_setup_boot_addr_wa'

The best solution seems to be to ensure that in this configuration,
we don't actually build any of the mvebu code.

Subject: Adding selftest testdata dynamically into live tree

This patch attaches selftest's device tree data (required by /drivers/of/selftest.c)
dynamically into live device tree. First, it links selftest device tree data into the
kernel image and then iterates over all the nodes and attaches them into the live tree.
Once the testcases are complete, it removes the data attached.

This patch will remove the manual process of addition and removal of selftest device
tree data into the machine's dts file.

Tested successfully with current selftest's testcases.

From 2695fb552cbef1029aa025a98acb80cc51d66de5 Mon Sep 17 00:00:00 2001
From: Alexei Starovoitov <ast@plumgrid.com>

Subject: net: filter: rename 'struct sock_filter_int' into 'struct bpf_insn'

eBPF is used by socket filtering, seccomp and soon by tracing and
exposed to userspace, therefore 'sock_filter_int' name is not accurate.
Rename it to 'bpf_insn'

Subject: ARM: OMAP2+: clock: allow omap2_dpll_round_rate() to round to
 next-lowest rate

Change the behavior of omap2_dpll_round_rate() to round to either the
exact rate requested, or the next lowest rate that the clock is able to
provide.

This is not an ideal fix, but is intended to provide a relatively safe
way for drivers to set PLL rates, until a better solution can be
implemented.

For the time being, omap3_noncore_dpll_set_rate() is still allowed to
set its rate to something other than what the caller requested; but will
warn when this occurs.

The debug uart settings from the DEBUG_RK3X_UART options are usable on

new rk3288 SoCs. Thus clarify their use to prevent confusion.

Subject: ARM: dts: rockchip: add cru nodes and update device clocks to use it

This adds a node for the clock and reset unit on rk3188 and rk3066 SoCs and
also updates the device nodes retrieve their clocks from there, instead of
the previous gate clock nodes.

From 560106c1ca063e7cbbb527c0df2c6929cb36c6ae Mon Sep 17 00:00:00 2001
From: Heiko Stuebner <heiko@sntech.de>
Date: Tue, 15 Apr 2014 19:44:59 +0200
Subject: ARM: dts: rockchip: move oscillator input clock into main dtsi

The clock definitions get a lot shorter due to the soc clocks being handled by
rk3188-cru and only the input clock remains. These can now simply live
in the main rk3xxx.dtsi without affecting readability.

At the same time, rename the node to oscillator, adding a clock-output-names
property to match how the rk3288 handles this.

Subject: arm: dts: rockchip: remove obsolete clock gate definitions

The clock and reset unit is now provided by the rk3188-cru clock driver and thus
the old style definitions of the gate clocks can go away.

Subject: ARM: dts: rockchip: remove soc subnodes

Comments received from the rk3288 submission indicated that a generic subnode
to group soc components should not be used.

So to keep all rockchip devicetree files similar, remove it from rk3066 and rk3188.

Subject: ARM: dts: rockchip: add handles for shared nodes that don't have one
 yet

Some nodes that are changed in the dtsi hierarchy do not have handles yet.
As it was suggested in the rk3288 submission to do subsequent nodes changes
through such handle-references, add the missing ones.

Subject: ARM: dts: rockchip: remove address from pinctrl nodes

Subject: ARM: dts: rockchip: add tps65910 regulator for bqcurie2

The Curie2 uses a tps659102 as its main pmic, so add the i2c1 and tps65910
node as well as define the used voltages and regulator-names according to
the schematics.

Also fix the supply of the sd0 regulator, as it is supplied by the vio reg.

Subject: staging: silicom: remove driver
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The driver hasn't been cleaned up and it doesn't look like anyone is
working on it anymore (including the original author). So remove it.
If someone wants to work on cleaning the driver up and moving it out of
staging, this commit can be reverted.

In addition, since this removes the CONFIG_NET_VENDOR_SILICOM config
symbol, remove the symbol from all defconfig files that reference it.

-Theory of Operation:
-
-The Silicom Bypass Network Interface Cards (NICs) are network cards with paired ports (2 or 4). 
-The pairs either act as a "wire" allowing the network packets to pass or insert the device in 
-between the two ports.  When paired with the on-board hardware watchdog or other failsafe, 
-they provide high availability for the network in the face of software outages or maintenance.
-
-The software requirements are for a kernel level driver that interfaces with the bypass and watchdog,
-as well as for control software. User control can be either the provided standalone executable 
-(/bin/bpctl) or the API exposed by the Silicom library.

Subject: powerpc: Use standard macros for sys_sigpending() &
 sys_old_getrlimit()

Currently we have sys_sigpending and sys_old_getrlimit defined to use
COMPAT_SYS() in systbl.h, but then both are #defined to sys_ni_syscall
in systbl.S.

This seems to have been done when ppc and ppc64 were merged, in commit
9994a33 "Introduce entry_{32,64}.S, misc_{32,64}.S, systbl.S".

AFAICS there's no longer (or never was) any need for this, we can just
use SYSX() for both and remove the #defines to sys_ni_syscall.

The expansion before was:

  #define COMPAT_SYS(func)	.llong	.sys_##func,.compat_sys_##func
  #define sys_old_getrlimit sys_ni_syscall
  COMPAT_SYS(old_getrlimit)
  =>
  .llong	.sys_old_getrlimit,.compat_sys_old_getrlimit
  =>
  .llong	.sys_ni_syscall,.compat_sys_old_getrlimit

After is:

  #define SYSX(f, f3264, f32)	.llong	.f,.f3264
  SYSX(sys_ni_syscall, compat_sys_old_getrlimit, sys_old_getrlimit)
  =>
  .llong	.sys_ni_syscall,.compat_sys_old_getrlimit

ie. they are equivalent.

Finally both COMPAT_SYS() and SYSX() evaluate to sys_ni_syscall in the
Cell SPU code.

Subject: powerpc: Drop support for pre-POWER4 cpus

We inadvertently broke power3 support back in 3.4 with commit
f5339277eb8d "powerpc: Remove FW_FEATURE ISERIES from arch code".
No one noticed until at least 3.9.

By then we'd also broken it with the optimised memcpy, copy_to/from_user
and clear_user routines. We don't want to add any more complexity to
those just to support ancient cpus, so it seems like it's a good time to
drop support for power3 and earlier.

Subject: powerpc: Remove STAB code

Old cpus didn't have a Segment Lookaside Buffer (SLB), instead they had
a Segment Table (STAB). Now that we've dropped support for those cpus,
we can remove the STAB support entirely.

Subject: powerpc: Remove MMU_FTR_SLB

We now only support cpus that use an SLB, so we don't need an MMU
feature to indicate that.

Now that we have dropped power3 support we can remove CONFIG_POWER3. The
usage in pgtable_32.c was already dead code as CONFIG_POWER3 was not
selectable on PPC32.

Subject: powerpc: Remove CONFIG_POWER4

Although the name CONFIG_POWER4 suggests that it controls support for
power4 cpus, this symbol is actually misnamed.

It is a historical wart from the powermac code, which used to support
building a 32-bit kernel for power4. CONFIG_POWER4 was used in that
context to guard code that was 64-bit only.

In the powermac code we can just use CONFIG_PPC64 instead, and in other
places it is a synonym for CONFIG_PPC_BOOK3S_64.

Subject: powerpc: Remove CLASSIC_PPC

We have a strange #define in cputable.h called CLASSIC_PPC.

Although it is defined for 32 & 64bit, it's only used for 32bit and
it's basically a duplicate of CONFIG_PPC_BOOK3S_32, so let's use
the latter.

Subject: powerpc: Move bad_stack() below the fwnmi_data_area

At the moment the allmodconfig build is failing because we run out of
space between altivec_assist() at 0x5700 and the fwnmi_data_area at
0x7000.

Fixing it permanently will take some more work, but a quick fix is to
move bad_stack() below the fwnmi_data_area. That gives us just enough
room with everything enabled.

bad_stack() is called from the common exception handlers, but it's a
non-conditional branch, so we have plenty of scope to move it further
way.

Subject: powerpc: Update comments in irqflags.h

The comment on TRACE_ENABLE_INTS is incorrect, and appears to have
always been incorrect since the code was merged. It probably came from
an original out-of-tree patch.

Replace it with something that's correct. Also propagate the message to
RECONCILE_IRQ_STATE(), because it's potentially subtle.

Subject: powerpc: Remove misleading DISABLE_INTS

DISABLE_INTS has a long and storied history, but for some time now it
has not actually disabled interrupts.

For the open-coded exception handlers, just stop using it, instead call
RECONCILE_IRQ_STATE directly. This has the benefit of removing a level
of indirection, and making it clear that r10 & r11 are used at that
point.

For the addition case we still need a macro, so rename it to clarify
what it actually does.

Subject: powerpc/powernv: Switch powernv drivers to use machine_xxx_initcall()

A lot of the code in platforms/powernv is using non-machine initcalls.
That means if a kernel built with powernv support runs on another
platform, for example pseries, the initcalls will still run.

That is usually OK, because the initcalls will check for something in
the device tree or elsewhere before doing anything, so on other
platforms they will usually just return.

But it's fishy for powernv code to be running on other platforms, so
switch them all to be machine initcalls. If we want any of them to run
on other platforms in future they should move to sysdev.

Subject: powerpc/pseries: Switch pseries drivers to use machine_xxx_initcall()

A lot of the code in platforms/pseries is using non-machine initcalls.
That means if a kernel built with pseries support runs on another
platform, for example powernv, the initcalls will still run.

Most of these cases are OK, though sometimes only due to luck. Some were
having more effect:

 * hcall_inst_init
  - Checking FW_FEATURE_LPAR which is set on ps3 & celleb.
 * mobility_sysfs_init
  - created sysfs files unconditionally
  - but no effect due to ENOSYS from rtas_ibm_suspend_me()
 * apo_pm_init
  - created sysfs, allows write
  - nothing checks the value written to though
 * alloc_dispatch_log_kmem_cache
  - creating kmem_cache on non-pseries machines

Subject: powerpc/perf: Clear all MMCR settings before calling compute_mmcr()

Because we reuse cpuhw->mmcr on each call to compute_mmcr() there's a
risk that we could forget to set one of the values and use whatever
value was in there previously.

Currently all the implementations are careful to set all the values, but
it's safer to clear them all before we call compute_mmcr().

From 9de5cb0f6df83243c58b2d1e3754a3c237d954ff Mon Sep 17 00:00:00 2001
From: Michael Ellerman <mpe@ellerman.id.au>

Subject: powerpc/perf: Add per-event excludes on Power8

Power8 has a new register (MMCR2), which contains individual freeze bits
for each counter. This is an improvement on previous chips as it means
we can have multiple events on the PMU at the same time with different
exclude_{user,kernel,hv} settings. Previously we had to ensure all
events on the PMU had the same exclude settings.

The core of the patch is fairly simple. We use the 207S feature flag to
indicate that the PMU backend supports per-event excludes, if it's set
we skip the generic logic that enforces the equality of excludes between
events. We also use that flag to skip setting the freeze bits in MMCR0,
the PMU backend is expected to have handled setting them in MMCR2.

The complication arises with EBB. The FCxP bits in MMCR2 are accessible
R/W to a task using EBB. Which means a task using EBB will be able to
see that we are using MMCR2 for freezing, whereas the old logic which
used MMCR0 is not user visible.

The task can not see or affect exclude_kernel & exclude_hv, so we only
need to consider exclude_user.

The table below summarises the behaviour both before and after this
commit is applied:

 exclude_user           true  false
 ------------------------------------
        | User visible |  N    N
 Before | Can freeze   |  Y    Y
        | Can unfreeze |  N    Y
 ------------------------------------
        | User visible |  Y    Y
  After | Can freeze   |  Y    Y
        | Can unfreeze |  Y/N  Y
 ------------------------------------

So firstly I assert that the simple visibility of the exclude_user
setting in MMCR2 is a non-issue. The event belongs to the task, and
was most likely created by the task. So the exclude_user setting is not
privileged information in any way.

Secondly, the behaviour in the exclude_user = false case is unchanged.
This is important as it is the case that is actually useful, ie. the
event is created with no exclude setting and the task uses MMCR2 to
implement exclusion manually.

For exclude_user = true there is no meaningful change to freezing the
event. Previously the task could use MMCR2 to freeze the event, though
it was already frozen with MMCR0. With the new code the task can use
MMCR2 to freeze the event, though it was already frozen with MMCR2.

The only real change is when exclude_user = true and the task tries to
use MMCR2 to unfreeze the event. Previously this had no effect, because
the event was already frozen in MMCR0. With the new code the task can
unfreeze the event in MMCR2, but at some indeterminate time in the
future the kernel will overwrite its setting and refreeze the event.

Therefore my final assertion is that any task using exclude_user = true
and also fiddling with MMCR2 was deeply confused before this change, and
remains so after it.

The syscall_set_return_value function of s390 negates the error argument
before storing the value to the return register gpr2. This is incorrect,
the seccomp code already passes the negative error value.
Store the unmodified error value to gpr2.

Subject: s390/irq: improve displayed interrupt order in /proc/interrupts

Rework the irqclass_main_desc and irqclass_sub_desc data structures which
are used to report detaild IRQ statistics in /proc/interrupts.  When
called from the procfs ops, the entries in the structures are processed
one by one.

The index of an IRQ in the structures is identical to its definition in
the "enum interruption_class".   To control and (re)order the displayed
sequence, introduce an irq member in each entry.  This helps to display
related IRQs together without changing the assigned number in the
interruption_class enumeration.  That means, adding and displaying new
IRQs are independent.
Finally, this new behavior improves to maintain a kernel ABI.

 Finally, GPIOs can be bound to devices and functions using platform data. Board
 files that desire to do so need to include the following header:
 
-	#include <linux/gpio/driver.h>
+	#include <linux/gpio/machine.h>
 
 GPIOs are mapped by the means of tables of lookups, containing instances of the
 gpiod_lookup structure. Two macros are defined to help declaring such mappings:

In some cases it is desired to move a channel to a specific event queue.
Such a use case is audio, where it is preferred that it is served with
highest priority compared to other DMA clients.

virtual time base register is a per VM, per cpu register that needs
to be saved and restored on vm exit and entry. Writing to VTB is not
allowed in the privileged mode.

Subject: KVM: PPC: Book3s PR: Disable AIL mode with OPAL

When we're using PR KVM we must not allow the CPU to take interrupts
in virtual mode, as the SLB does not contain host kernel mappings
when running inside the guest context.

To make sure we get good performance for non-KVM tasks but still
properly functioning PR KVM, let's just disable AIL whenever a vcpu
is scheduled in.

This is fundamentally different from how we deal with AIL on pSeries
type machines where we disable AIL for the whole machine as soon as
a single KVM VM is up.

The reason for that is easy - on pSeries we do not have control over
per-cpu configuration of AIL. We also don't want to mess with CPU hotplug
races and AIL configuration, so setting it per CPU is easier and more
flexible.

This patch fixes running PR KVM on POWER8 bare metal for me.

Subject: KVM: PPC: Book3s HV: Fix tlbie compile error

Some compilers complain about uninitialized variables in the compute_tlbie_rb
function. When you follow the code path you'll realize that we'll never get
to that point, but the compiler isn't all that smart.

So just default to 4k page sizes for everything, making the compiler happy
and the code slightly easier to read.

Both kvmppc_hv_entry_trampoline and kvmppc_entry_trampoline are
assembly functions that are exported to modules and also require
a valid r2.

As such we need to use _GLOBAL_TOC so we provide a global entry
point that establishes the TOC (r2).

Subject: KVM: PPC: Book3S PR: Fix ABIv2 on LE

We switched to ABIv2 on Little Endian systems now which gets rid of the
dotted function names. Branch to the actual functions when we see such
a system.

Subject: KVM: PPC: e500mc: Enhance tlb invalidation condition on vcpu schedule

On vcpu schedule, the condition checked for tlb pollution is too loose.
The tlb entries of a vcpu become polluted (vs stale) only when a different
vcpu within the same logical partition runs in-between. Optimize the tlb
invalidation condition keeping last_vcpu per logical partition id.

With the new invalidation condition, a guest shows 4% performance improvement
on P5020DS while running a memory stress application with the cpu oversubscribed,
the other guest running a cpu intensive workload.

Guest - old invalidation condition
  real 3.89
  user 3.87
  sys 0.01

Guest - enhanced invalidation condition
  real 3.75
  user 3.73
  sys 0.01

Host
  real 3.70
  user 1.85
  sys 0.00

The memory stress application accesses 4KB pages backed by 75% of available
TLB0 entries:

char foo[ENTRIES][4096] __attribute__ ((aligned (4096)));

int main()
{
	char bar;
	int i, j;

	for (i = 0; i < ITERATIONS; i++)
        	for (j = 0; j < ENTRIES; j++)
            		bar = foo[j][0];

	return 0;
}

Subject: KVM: PPC: Book3S: Controls for in-kernel sPAPR hypercall handling

This provides a way for userspace controls which sPAPR hcalls get
handled in the kernel.  Each hcall can be individually enabled or
disabled for in-kernel handling, except for H_RTAS.  The exception
for H_RTAS is because userspace can already control whether
individual RTAS functions are handled in-kernel or not via the
KVM_PPC_RTAS_DEFINE_TOKEN ioctl, and because the numeric value for
H_RTAS is out of the normal sequence of hcall numbers.

Hcalls are enabled or disabled using the KVM_ENABLE_CAP ioctl for the
KVM_CAP_PPC_ENABLE_HCALL capability on the file descriptor for the VM.
The args field of the struct kvm_enable_cap specifies the hcall number
in args[0] and the enable/disable flag in args[1]; 0 means disable
in-kernel handling (so that the hcall will always cause an exit to
userspace) and 1 means enable.  Enabling or disabling in-kernel
handling of an hcall is effective across the whole VM.

The ability for KVM_ENABLE_CAP to be used on a VM file descriptor
on PowerPC is new, added by this commit.  The KVM_CAP_ENABLE_CAP_VM
capability advertises that this ability exists.

When a VM is created, an initial set of hcalls are enabled for
in-kernel handling.  The set that is enabled is the set that have
an in-kernel implementation at this point.  Any new hcall
implementations from this point onwards should not be added to the
default set without a good reason.

No distinction is made between real-mode and virtual-mode hcall
implementations; the one setting controls them both.

Subject: KVM: PPC: Book3S: Allow only implemented hcalls to be enabled or
 disabled

This adds code to check that when the KVM_CAP_PPC_ENABLE_HCALL
capability is used to enable or disable in-kernel handling of an
hcall, that the hcall is actually implemented by the kernel.
If not an EINVAL error is returned.

This also checks the default-enabled list of hcalls and prints a
warning if any hcall there is not actually implemented.

Subject: KVM: PPC: Book3S HV: Add H_SET_MODE hcall handling

This adds support for the H_SET_MODE hcall.  This hcall is a
multiplexer that has several functions, some of which are called
rarely, and some which are potentially called very frequently.
Here we add support for the functions that set the debug registers
CIABR (Completed Instruction Address Breakpoint Register) and
DAWR/DAWRX (Data Address Watchpoint Register and eXtension),
since they could be updated by the guest as often as every context
switch.

This also adds a kvmppc_power8_compatible() function to test to see
if a guest is compatible with POWER8 or not.  The CIABR and DAWR/X
only exist on POWER8.

Subject: KVM: PPC: e500: Fix default tlb for victim hint

Tlb search operation used for victim hint relies on the default tlb set by the
host. When hardware tablewalk support is enabled in the host, the default tlb is
TLB1 which leads KVM to evict the bolted entry. Set and restore the default tlb
when searching for victim hint.

Subject: PPC: Add asm helpers for BE 32bit load/store

From assembly code we might not only have to explicitly BE access 64bit values,
but sometimes also 32bit ones. Add helpers that allow for easy use of lwzx/stwx
in their respective byte-reverse or native form.

Subject: KVM: PPC: Book3S HV: Make HTAB code LE host aware

When running on an LE host all data structures are kept in little endian
byte order. However, the HTAB still needs to be maintained in big endian.

So every time we access any HTAB we need to make sure we do so in the right
byte order. Fix up all accesses to manually byte swap.

Subject: KVM: PPC: Book3S HV: Access guest VPA in BE

There are a few shared data structures between the host and the guest. Most
of them get registered through the VPA interface.

These data structures are defined to always be in big endian byte order, so
let's make sure we always access them in big endian.

Some data structures are always stored in big endian. Among those are the LPPACA

So whenever we access those fields, make sure we do so in big endian byte order.

Subject: KVM: PPC: Book3S HV: Access XICS in BE

On the exit path from the guest we check what type of interrupt we received
if we received one. This means we're doing hardware access to the XICS interrupt
controller.

However, when running on a little endian system, this access is byte reversed.

So let's make sure to swizzle the bytes back again and virtually make XICS
accesses big endian.

For FSL e6500 core the kernel uses power management SPR register (PWRMGTCR0)
to enable idle power down for cores and devices by setting up the idle count

When building KVM with a lot of vcores (NR_CPUS is big), we can potentially
get out of the ld immediate range for dereferences inside that struct.

Move the array to the end of our kvm_arch struct. This fixes compilation
issues with NR_CPUS=2048 for me.

Subject: KVM: PPC: Deflect page write faults properly in kvmppc_st

When we have a page that we're not allowed to write to, xlate() will already
tell us -EPERM on lookup of that page. With the code as is we change it into
a "page missing" error which a guest may get confused about. Instead, just
tell the caller about the -EPERM directly.

This fixes Mac OS X guests when run with DCBZ32 emulation.

Subject: KVM: PPC: Book3S: Stop PTE lookup on write errors

When a page lookup failed because we're not allowed to write to the page, we
should not overwrite that value with another lookup on the second PTEG which
will return "page not found". Instead, we should just tell the caller that we
had a permission problem.

This fixes Mac OS X guests looping endlessly in page lookup code for me.

Subject: KVM: PPC: Book3S: Add hack for split real mode

Today we handle split real mode by mapping both instruction and data faults
into a special virtual address space that only exists during the split mode
phase.

This is good enough to catch 32bit Linux guests that use split real mode for
copy_from/to_user. In this case we're always prefixed with 0xc0000000 for our
instruction pointer and can map the user space process freely below there.

However, that approach fails when we're running KVM inside of KVM. Here the 1st
level last_inst reader may well be in the same virtual page as a 2nd level
interrupt handler.

It also fails when running Mac OS X guests. Here we have a 4G/4G split, so a
kernel copy_from/to_user implementation can easily overlap with user space
addresses.

The architecturally correct way to fix this would be to implement an instruction
interpreter in KVM that kicks in whenever we go into split real mode. This
interpreter however would not receive a great amount of testing and be a lot of
bloat for a reasonably isolated corner case.

So I went back to the drawing board and tried to come up with a way to make
split real mode work with a single flat address space. And then I realized that
we could get away with the same trick that makes it work for Linux:

Whenever we see an instruction address during split real mode that may collide,
we just move it higher up the virtual address space to a place that hopefully
does not collide (keep your fingers crossed!).

That approach does work surprisingly well. I am able to successfully run
Mac OS X guests with KVM and QEMU (no split real mode hacks like MOL) when I
apply a tiny timing probe hack to QEMU. I'd say this is a win over even more
broken split real mode :).

Subject: KVM: PPC: Book3S: Make magic page properly 4k mappable

The magic page is defined as a 4k page of per-vCPU data that is shared
between the guest and the host to accelerate accesses to privileged
registers.

However, when the host is using 64k page size granularity we weren't quite
as strict about that rule anymore. Instead, we partially treated all of the
upper 64k as magic page and mapped only the uppermost 4k with the actual
magic contents.

This works well enough for Linux which doesn't use any memory in kernel
space in the upper 64k, but Mac OS X got upset. So this patch makes magic
page actually stay in a 4k range even on 64k page size hosts.

This patch fixes magic page usage with Mac OS X (using MOL) on 64k PAGE_SIZE
hosts for me.

Subject: KVM: PPC: e500mc: Revert "add load inst fixup"

The commit 1d628af7 "add load inst fixup" made an attempt to handle
failures generated by reading the guest current instruction. The fixup
code that was added works by chance hiding the real issue.

Load external pid (lwepx) instruction, used by KVM to read guest
instructions, is executed in a subsituted guest translation context
(EPLC[EGS] = 1). In consequence lwepx's TLB error and data storage
interrupts need to be handled by KVM, even though these interrupts
are generated from host context (MSR[GS] = 0) where lwepx is executed.

Currently, KVM hooks only interrupts generated from guest context
(MSR[GS] = 1), doing minimal checks on the fast path to avoid host
performance degradation. As a result, the host kernel handles lwepx
faults searching the faulting guest data address (loaded in DEAR) in
its own Logical Partition ID (LPID) 0 context. In case a host translation
is found the execution returns to the lwepx instruction instead of the
fixup, the host ending up in an infinite loop.

Revert the commit "add load inst fixup". lwepx issue will be addressed
in a subsequent patch without needing fixup code.

Subject: KVM: PPC: Book3s: Remove kvmppc_read_inst() function

In the context of replacing kvmppc_ld() function calls with a version of
kvmppc_get_last_inst() which allow to fail, Alex Graf suggested this:

"If we get EMULATE_AGAIN, we just have to make sure we go back into the guest.
No need to inject an ISI into  the guest - it'll do that all by itself.
With an error returning kvmppc_get_last_inst we can just use completely
get rid of kvmppc_read_inst() and only use kvmppc_get_last_inst() instead."

As a intermediate step get rid of kvmppc_read_inst() and only use kvmppc_ld()
instead.

Subject: KVM: PPC: Allow kvmppc_get_last_inst() to fail

On book3e, guest last instruction is read on the exit path using load
external pid (lwepx) dedicated instruction. This load operation may fail
due to TLB eviction and execute-but-not-read entries.

This patch lay down the path for an alternative solution to read the guest
last instruction, by allowing kvmppc_get_lat_inst() function to fail.
Architecture specific implmentations of kvmppc_load_last_inst() may read
last guest instruction and instruct the emulation layer to re-execute the
guest in case of failure.

Make kvmppc_get_last_inst() definition common between architectures.

From f5250471b2d6ad27d536cb34ce39d76b91b2b36b Mon Sep 17 00:00:00 2001
From: Mihai Caraman <mihai.caraman@freescale.com>
Date: Wed, 23 Jul 2014 19:06:22 +0300
Subject: KVM: PPC: Bookehv: Get vcpu's last instruction for emulation

On book3e, KVM uses load external pid (lwepx) dedicated instruction to read
guest last instruction on the exit path. lwepx exceptions (DTLB_MISS, DSI
and LRAT), generated by loading a guest address, needs to be handled by KVM.
These exceptions are generated in a substituted guest translation context
(EPLC[EGS] = 1) from host context (MSR[GS] = 0).

Currently, KVM hooks only interrupts generated from guest context (MSR[GS] = 1),
doing minimal checks on the fast path to avoid host performance degradation.
lwepx exceptions originate from host state (MSR[GS] = 0) which implies
additional checks in DO_KVM macro (beside the current MSR[GS] = 1) by looking
at the Exception Syndrome Register (ESR[EPID]) and the External PID Load Context
Register (EPLC[EGS]). Doing this on each Data TLB miss exception is obvious
too intrusive for the host.

Read guest last instruction from kvmppc_load_last_inst() by searching for the
physical address and kmap it. This address the TODO for TLB eviction and
execute-but-not-read entries, and allow us to get rid of lwepx until we are
able to handle failures.

A simple stress benchmark shows a 1% sys performance degradation compared with
previous approach (lwepx without failure handling):

time for i in `seq 1 10000`; do /bin/echo > /dev/null; done

real    0m 8.85s
user    0m 4.34s
sys     0m 4.48s

vs

real    0m 8.84s
user    0m 4.36s
sys     0m 4.44s

A solution to use lwepx and to handle its exceptions in KVM would be to temporary
highjack the interrupt vector from host. This imposes additional synchronizations
for cores like FSL e6500 that shares host IVOR registers between hardware threads.
This optimized solution can be later developed on top of this patch.

Subject: KVM: PPC: Booke-hv: Add one reg interface for SPRG9

We now support SPRG9 for guest, so also add a one reg interface for same
Note: Changes are in bookehv code only as we do not have SPRG9 on booke-pr.

Subject: KVM: PPC: Remove comment saying SPRG1 is used for vcpu pointer

Scott Wood pointed out that We are no longer using SPRG1 for vcpu pointer,
but using SPRN_SPRG_THREAD <=> SPRG3 (thread->vcpu). So this comment
is not valid now.

Note: SPRN_SPRG3R is not supported (do not see any need as of now),
and if we want to support this in future then we have to shift to using
SPRG1 for VCPU pointer.

Subject: KVM: PPC: Remove 440 support

The 440 target hasn't been properly functioning for a few releases and
before I was the only one who fixes a very serious bug that indicates to
me that nobody used it before either.

Furthermore KVM on 440 is slow to the extent of unusable.

We don't have to carry along completely unused code. Remove 440 and give
us one less thing to worry about.

-Various notes on the implementation of KVM for PowerPC 440:
-
-To enforce isolation, host userspace, guest kernel, and guest userspace all
-run at user privilege level. Only the host kernel runs in supervisor mode.
-Executing privileged instructions in the guest traps into KVM (in the host
-kernel), where we decode and emulate them. Through this technique, unmodified
-440 Linux kernels can be run (slowly) as guests. Future performance work will
-focus on reducing the overhead and frequency of these traps.
-
-The usual code flow is started from userspace invoking an "run" ioctl, which
-causes KVM to switch into guest context. We use IVPR to hijack the host
-interrupt vectors while running the guest, which allows us to direct all
-interrupts to kvmppc_handle_interrupt(). At this point, we could either
-- handle the interrupt completely (e.g. emulate "mtspr SPRG0"), or
-- let the host interrupt handler run (e.g. when the decrementer fires), or
-- return to host userspace (e.g. when the guest performs device MMIO)
-
-Address spaces: We take advantage of the fact that Linux doesn't use the AS=1
-address space (in host or guest), which gives us virtual address space to use
-for guest mappings. While the guest is running, the host kernel remains mapped
-in AS=0, but the guest can only use AS=1 mappings.
-
-TLB entries: The TLB entries covering the host linear mapping remain
-present while running the guest. This reduces the overhead of lightweight
-exits, which are handled by KVM running in the host kernel. We keep three
-copies of the TLB:
- - guest TLB: contents of the TLB as the guest sees it
- - shadow TLB: the TLB that is actually in hardware while guest is running
- - host TLB: to restore TLB state when context switching guest -> host
-When a TLB miss occurs because a mapping was not present in the shadow TLB,
-but was present in the guest TLB, KVM handles the fault without invoking the
-guest. Large guest pages are backed by multiple 4KB shadow pages through this
-mechanism.
-
-IO: MMIO and DCR accesses are emulated by userspace. We use virtio for network
-and block IO, so those drivers must be enabled in the guest. It's possible
-that some qemu device emulation (e.g. e1000 or rtl8139) may also work with
-little effort.

From a0840240c0c6bcbac8f0f5db11f95c19aaf9b52f Mon Sep 17 00:00:00 2001
From: Alexey Kardashevskiy <aik@ozlabs.ru>
Date: Sat, 19 Jul 2014 17:59:34 +1000
Subject: KVM: PPC: Book3S: Fix LPCR one_reg interface

Unfortunately, the LPCR got defined as a 32-bit register in the
one_reg interface.  This is unfortunate because KVM allows userspace
to control the DPFD (default prefetch depth) field, which is in the
upper 32 bits.  The result is that DPFD always get set to 0, which
reduces performance in the guest.

We can't just change KVM_REG_PPC_LPCR to be a 64-bit register ID,
since that would break existing userspace binaries.  Instead we define
a new KVM_REG_PPC_LPCR_64 id which is 64-bit.  Userspace can still use
the old KVM_REG_PPC_LPCR id, but it now only modifies those fields in
the bottom 32 bits that userspace can modify (ILE, TC and AIL).
If userspace uses the new KVM_REG_PPC_LPCR_64 id, it can modify DPFD
as well.

Subject: KVM: PPC: Book3S PR: Take SRCU read lock around RTAS kvm_read_guest()
 call

This does for PR KVM what c9438092cae4 ("KVM: PPC: Book3S HV: Take SRCU
read lock around kvm_read_guest() call") did for HV KVM, that is,
eliminate a "suspicious rcu_dereference_check() usage!" warning by
taking the SRCU lock around the call to kvmppc_rtas_hcall().

It also fixes a return of RESUME_HOST to return EMULATE_FAIL instead,
since kvmppc_h_pr() is supposed to return EMULATE_* values.

Subject: KVM: PPC: Book3S: Make kvmppc_ld return a more accurate error
 indication

At present, kvmppc_ld calls kvmppc_xlate, and if kvmppc_xlate returns
any error indication, it returns -ENOENT, which is taken to mean an
HPTE not found error.  However, the error could have been a segment
found (no SLB entry) or a permission error.  Similarly,
kvmppc_pte_to_hva currently does permission checking, but any error
from it is taken by kvmppc_ld to mean that the access is an emulated
MMIO access.  Also, kvmppc_ld does no execute permission checking.

This fixes these problems by (a) returning any error from kvmppc_xlate
directly, (b) moving the permission check from kvmppc_pte_to_hva
into kvmppc_ld, and (c) adding an execute permission check to kvmppc_ld.

This is similar to what was done for kvmppc_st() by commit 82ff911317c3
("KVM: PPC: Deflect page write faults properly in kvmppc_st").

Subject: Use the POWER8 Micro Partition Prefetch Engine in KVM HV on POWER8

The POWER8 processor has a Micro Partition Prefetch Engine, which is
a fancy way of saying "has way to store and load contents of L2 or
L2+MRU way of L3 cache". We initiate the storing of the log (list of
addresses) using the logmpp instruction and start restore by writing
to a SPR.

The logmpp instruction takes parameters in a single 64bit register:
- starting address of the table to store log of L2/L2+L3 cache contents
  - 32kb for L2
  - 128kb for L2+L3
  - Aligned relative to maximum size of the table (32kb or 128kb)
- Log control (no-op, L2 only, L2 and L3, abort logout)

We should abort any ongoing logging before initiating one.

To initiate restore, we write to the MPPR SPR. The format of what to write
to the SPR is similar to the logmpp instruction parameter:
- starting address of the table to read from (same alignment requirements)
- table size (no data, until end of table)
- prefetch rate (from fastest possible to slower. about every 8, 16, 24 or
  32 cycles)

The idea behind loading and storing the contents of L2/L3 cache is to
reduce memory latency in a system that is frequently swapping vcores on
a physical CPU.

The best case scenario for doing this is when some vcores are doing very
cache heavy workloads. The worst case is when they have about 0 cache hits,
so we just generate needless memory operations.

This implementation just does L2 store/load. In my benchmarks this proves
to be useful.

Benchmark 1:
 - 16 core POWER8
 - 3x Ubuntu 14.04LTS guests (LE) with 8 VCPUs each
 - No split core/SMT
 - two guests running sysbench memory test.
   sysbench --test=memory --num-threads=8 run
 - one guest running apache bench (of default HTML page)
   ab -n 490000 -c 400 http://localhost/

This benchmark aims to measure performance of real world application (apache)
where other guests are cache hot with their own workloads. The sysbench memory
benchmark does pointer sized writes to a (small) memory buffer in a loop.

In this benchmark with this patch I can see an improvement both in requests
per second (~5%) and in mean and median response times (again, about 5%).
The spread of minimum and maximum response times were largely unchanged.

benchmark 2:
 - Same VM config as benchmark 1
 - all three guests running sysbench memory benchmark

This benchmark aims to see if there is a positive or negative affect to this
cache heavy benchmark. Although due to the nature of the benchmark (stores) we
may not see a difference in performance, but rather hopefully an improvement
in consistency of performance (when vcore switched in, don't have to wait
many times for cachelines to be pulled in)

The results of this benchmark are improvements in consistency of performance
rather than performance itself. With this patch, the few outliers in duration
go away and we get more consistent performance in each guest.

benchmark 3:
 - same 3 guests and CPU configuration as benchmark 1 and 2.
 - two idle guests
 - 1 guest running STREAM benchmark

This scenario also saw performance improvement with this patch. On Copy and
Scale workloads from STREAM, I got 5-6% improvement with this patch. For
Add and triad, it was around 10% (or more).

benchmark 4:
 - same 3 guests as previous benchmarks
 - two guests running sysbench --memory, distinctly different cache heavy
   workload
 - one guest running STREAM benchmark.

Similar improvements to benchmark 3.

benchmark 5:
 - 1 guest, 8 VCPUs, Ubuntu 14.04
 - Host configured with split core (SMT8, subcores-per-core=4)
 - STREAM benchmark

In this benchmark, we see a 10-20% performance improvement across the board
of STREAM benchmark results with this patch.

Based on preliminary investigation and microbenchmarks

Subject: KVM: Rename and add argument to check_extension

In preparation to make the check_extension function available to VM scope
we add a struct kvm * argument to the function header and rename the function
accordingly. It will still be called from the /dev/kvm fd, but with a NULL
argument for struct kvm *.

Subject: KVM: PPC: Book3S: Provide different CAPs based on HV or PR mode

With Book3S KVM we can create both PR and HV VMs in parallel on the same
machine. That gives us new challenges on the CAPs we return - both have
different capabilities.

When we get asked about CAPs on the kvm fd, there's nothing we can do. We
can try to be smart and assume we're running HV if HV is available, PR
otherwise. However with the newly added VM CHECK_EXTENSION we can now ask
for capabilities directly on a VM which knows whether it's PR or HV.

With this patch I can successfully expose KVM PVINFO data to user space
in the PR case, fixing magic page mapping for PAPR guests.

Subject: ARM: add SMP support for Broadcom mobile SoCs

This patch adds SMP support for BCM281XX and BCM21664 family SoCs.

This feature is controlled with a distinct config option such that
an SMP-enabled multi-v7 binary can be configured to run these SoCs
in uniprocessor mode.  Since this SMP functionality is used for
multiple Broadcom mobile chip families the config option is called
ARCH_BCM_MOBILE_SMP (for lack of a better name).

On SoCs of this type, the secondary core is not held in reset on
power-on.  Instead it loops in a ROM-based holding pen.  To release
it, one must write into a special register a jump address whose
low-order bits have been replaced with a secondary core's id, then
trigger an event with SEV.  On receipt of an event, the ROM code
will examine the register's contents, and if the low-order bits
match its cpu id, it will clear them and write the value back to the
register just prior to jumping to the address specified.

The location of the special register is defined in the device tree
using a "secondary-boot-reg" property in a node whose "enable-method"
matches.

Subject: KVM: PPC: BOOK3S: HV: Update compute_tlbie_rb to handle 16MB base

When calculating the lower bits of AVA field, use the shift
count based on the base page size. Also add the missing segment
size and remove stale comment.

Subject: KVM: PPC: Implement kvmppc_xlate for all targets

We have a nice API to find the translated GPAs of a GVA including protection
flags. So far we only use it on Book3S, but there's no reason the same shouldn't
be used on BookE as well.

Implement a kvmppc_xlate() version for BookE and clean it up to make it more
readable in general.

Subject: KVM: PPC: Move kvmppc_ld/st to common code

We have enough common infrastructure now to resolve GVA->GPA mappings at
runtime. With this we can move our book3s specific helpers to load / store
in guest virtual address space to common code as well.

We have a nice and handy helper to read from guest physical address space,
so we should make use of it in kvmppc_ld as we already do for its counterpart
in kvmppc_st.

Subject: KVM: PPC: Separate loadstore emulation from priv emulation

Today the instruction emulator can get called via 2 separate code paths. It
can either be called by MMIO emulation detection code or by privileged
instruction traps.

This is bad, as both code paths prepare the environment differently. For MMIO
emulation we already know the virtual address we faulted on, so instructions
there don't have to actually fetch that information.

Split out the two separate use cases into separate files.

Subject: KVM: PPC: Expose helper functions for data/inst faults

We're going to implement guest code interpretation in KVM for some rare
corner cases. This code needs to be able to inject data and instruction
faults into the guest when it encounters them.

Expose generic APIs to do this in a reasonably subarch agnostic fashion.

Subject: mailbox/omap: remove OMAP1 mailbox driver

There are no existing users for OMAP1 mailbox driver
in kernel. Commit ab6f775 "Removing dead OMAP_DSP"
has cleaned up all the dead code related to the only
possible user, including the creation of the mailbox
platform device.

Remove this stale driver so that the OMAP mailbox
driver can be simplified and streamlined better for
converting to mailbox framework.

Subject: ARM: 8113/1: remove remaining definitions of PLAT_PHYS_OFFSET from
 <mach/memory.h>
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The platforms selecting NEED_MACH_MEMORY_H defined the start address of
their physical memory in the respective <mach/memory.h>. With
ARM_PATCH_PHYS_VIRT=y (which is quite common today) this is useless
though because the definition isn't used but determined dynamically.

So remove the definitions from all <mach/memory.h> and provide the
Kconfig symbol PHYS_OFFSET with the respective defaults in case
ARM_PATCH_PHYS_VIRT isn't enabled.

This allows to drop the dependency of PHYS_OFFSET on !NEED_MACH_MEMORY_H
which prevents compiling an integrator nommu-kernel.
(CONFIG_PAGE_OFFSET which has "default PHYS_OFFSET if !MMU" expanded to
"0x" because CONFIG_PHYS_OFFSET doesn't exist as INTEGRATOR selects
NEED_MACH_MEMORY_H.)

Subject: ARM: dts: max77686 is exynos5250-snow only

Move it from exynos5250-cros-common.dtsi to exynos5250-snow.dts.
Spring does not need it, it uses an s5m8767 instead.

Subject: ARM: dts: cypress,cyapa trackpad is exynos5250-Snow only

Move it from exynos5250-cros-common.dtsi to exynos5250-snow.dts.
Spring does not need it, it uses an Atmel maXTouch instead.

Subject: powerpc/booke: Define MSR bits the same way as reg.h

This ensures that all MSR definitions are consistently unsigned long,
and that MSR_CM does not become 0xffffffff80000000 (this is usually
harmless because MSR is 32-bit on booke and is mainly noticeable when
debugging, but still I'd rather avoid it).

Subject: powerpc/e6500: Add support for hardware threads

The general idea is that each core will release all of its
threads into the secondary thread startup code, which will
eventually wait in the secondary core holding area, for the
appropriate bit in the PACA to be set. The kick_cpu function
pointer will set that bit in the PACA, and thus "release"
the core/thread to boot. We also need to do a few things that
U-Boot normally does for CPUs (like enable branch prediction).

 threads if Linux wants to kick them]

Subject: powerpc/e6500: Work around erratum A-008139

Erratum A-008139 can cause duplicate TLB entries if an indirect
entry is overwritten using tlbwe while the other thread is using it to
do a lookup.  Work around this by using tlbilx to invalidate prior
to overwriting.

To avoid the need to save another register to hold MAS1 during the
workaround code, TID clearing has been moved from tlb_miss_kernel_e6500
until after the SMT section.

Subject: memory: Freescale CoreNet Coherency Fabric error reporting driver

The CoreNet Coherency Fabric is part of the memory subsystem on
some Freescale QorIQ chips.  It can report coherency violations (e.g.
due to misusing memory that is mapped noncoherent) as well as
transactions that do not hit any local access window, or which hit a
local access window with an invalid target ID.

Subject: powerpc/mpic_msgr: Use kcalloc and correct the argument to sizeof

mpic_msgrs has type struct mpic_msgr **, not struct mpic_msgr *, so the
elements of the array should have pointer type, not structure type.
The advantage of kcalloc is, that will prevent integer overflows which
could result from the multiplication of number of elements and size and
it is also a bit nicer to read.

The Coccinelle semantic patch that makes the first change is as follows:

// <smpl>
@disable sizeof_type_expr@
type T;
T **x;
@@

  x =
  <+...sizeof(
- T
+ *x
  )...+>
// </smpl>

Subject: powerpc/fsl-pci: Correct use of ! and &

In commit ae91d60ba88ef0bdb1b5e9b2363bd52fc45d2af7, a bug was fixed that
involved converting !x & y to !(x & y).  The code below shows the same
pattern, and thus should perhaps be fixed in the same way.

This is not tested and clearly changes the semantics, so it is only
something to consider.

The Coccinelle semantic patch that makes this change is as follows:

// <smpl>
@@ expression E1,E2; @@
(
  !E1 & !E2
|
- !E1 & E2
+ !(E1 & E2)

Subject: timekeeping: Fixup typo in update_vsyscall_old definition

In commit 4a0e637738f0 ("clocksource: Get rid of cycle_last"),
currently in the -tip tree, there was a small typo where cycles_t
was used intstead of cycle_t. This broke ppc64 builds.

Fix this by using the proper cycle_t type for this usage, in
both the definition and the ia64 implementation.

Now, having both cycle_t and cycles_t types seems like a very
bad idea just asking for these sorts of issues. But that
will be a cleanup for another day.

[ralf@linux-mips.org: Reformat to Linux coding style and make
gio_bus_release static.]

Subject: MIPS: RB532: Fix reregistering of serial console

Runtime tested on Mikrotik RB532 board.
Thanks goes to Geert Uytterhoeven for the explanation of the problem.

"I'm afraid this is not gonna help. When the port is unregistered,
its type will be reset to PORT_UNKNOWN.
So before registering it again, its type must be set again the actual
serial driver, cfr. the change to of_serial.c."

From 2ef1bb99116e49226e8bab8ebab255f12fa8a99e Mon Sep 17 00:00:00 2001

Subject: MIPS: Alchemy: au1000.h move C-code after register definitions.

Move the C-code after all macros:  A follow-on patch which
introduces helpers to access the SYS_* registers needs this to build.

Just code shuffling, no functional changes.

From 1d09de7dc76ef96a9a2c7c0244e20f12d68e6ef8 Mon Sep 17 00:00:00 2001
From: Manuel Lauss <manuel.lauss@gmail.com>
Date: Wed, 23 Jul 2014 16:36:24 +0200
Subject: MIPS: Alchemy: introduce helpers to access SYS register block.

This patch changes all absolute SYS_XY registers to offsets from the
SYS block base, prefixes them with AU1000 to avoid silent failures due
to changed addresses, and introduces helper functions to read/write
them.

No functional changes, comparing assembly of a few select functions shows
no differences.

From 9cf12167e909a86fbc4b39cf4cffef4cba40f1b3 Mon Sep 17 00:00:00 2001
From: Manuel Lauss <manuel.lauss@gmail.com>
Date: Wed, 23 Jul 2014 16:36:25 +0200
Subject: MIPS: Alchemy: add helpers to access static memory ctrl registers.

This patch changes the static memory controller registers to offsets
from base, prefixes them with AU1000_ to avoid silent failures due to
changed addresses and introduces helpers to access them.

No functional changes, comparing assembly of a few select functions shows
no differences.

Subject: MIPS: Alchemy: clock framework integration of onchip clocks

This patch introduces common clock framework integration for all
configurable on-chip clocks on Alchemy chips:

- 2 or 3 PLLs which generate integer multiples of the root rate 12MHz,
- 6 dividers which take one of the 3 PLLs as input and divide their
  rate by either multiples of 2 or 1 (Au1300).
- another bank of up to 6 muxes which take either one of the 6
  above dividers or one of the PLLs directly and divide their rate
  further by 1, 2, 3 or 4.
- a few other sources which are used by onchip peripherals and are
  informational.

This implementation will take the clock tree as it was set up
by boot firmware: all in-kernel boards should continue to work
without having to set up the clock tree in board code.

CLK_IGNORE_DISABLED will be removed once all drivers have been
converted.

+ * Alchemy clocks.
+ *
+ * Exposes all configurable internal clock sources to the clk framework.
+ *
+ * We have:
+ *  - Root source, usually 12MHz supplied by an external crystal
+ *  - 3 PLLs which generate multiples of root rate [AUX, CPU, AUX2]
+ *
+ * Dividers:
+ *  - 6 clock dividers with:
+ *   * selectable source [one of the PLLs],
+ *   * output divided between [2 .. 512 in steps of 2] (!Au1300)
+ *     or [1 .. 256 in steps of 1] (Au1300),
+ *   * can be enabled individually.
+ *
+ * - up to 6 "internal" (fixed) consumers which:
+ *   * take either AUXPLL or one of the above 6 dividers as input,
+ *   * divide this input by 1, 2, or 4 (and 3 on Au1300).
+ *   * can be disabled separately.
+ *
+ * Misc clocks:
+ * - sysbus clock: CPU core clock (CPUPLL) divided by 2, 3 or 4.
+ *    depends on board design and should be set by bootloader, read-only.
+ * - peripheral clock: half the rate of sysbus clock, source for a lot
+ *    of peripheral blocks, read-only.
+ * - memory clock: clk rate to main memory chips, depends on board
+ *    design and is read-only,
+ * - lrclk: the static bus clock signal for synchronous operation.
+ *    depends on board design, must be set by bootloader,
+ *    but may be required to correctly configure devices attached to
+ *    the static bus. The Au1000/1500/1100 manuals call it LCLK, on
+ *    later models it's called RCLK.

Subject: MIPS: Alchemy: usb: use clk framework

Add use of the common clock framework to set and enable the 48MHz
clock source for the onchip OHCI and UDC blocks.

Tested on a DB1500.  (Au1200 and Au1300 use an external 48MHz crystal).

Subject: MIPS: Alchemy: remove old clock support

With the clock framework in place, remove unused functions and bits,
and drop the CLK_IGNORE_UNUSED flag, which is now unneeded.

Subject: MIPS: tlbex: Fix a missing statement for HUGETLB

In commit 2c8c53e28f1 (MIPS: Optimize TLB handlers for Octeon CPUs)
build_r4000_tlb_refill_handler() is modified. But it doesn't compatible
with the original code in HUGETLB case. Because there is a copy & paste
error and one line of code is missing. It is very easy to produce a bug
with LTP's hugemmap05 test.

Subject: MIPS: BCM63xx: Sync MIPS counters during CPU bringup

We are using the mips counters as the clock source, so we need to ensure
they are synced, else e.g. gettimeofday will return different values
depending on which core it was run.

Observed difference was about 8 seconds, causing ~8 seconds ping or time
running backwards for some programs.

Subject: MIPS: BCM63xx: Remove !RUNTIME_DETECT in cpu-feature-overrides

All three SoCs have in common they have a BMIPS32/BMIPS3300 CPU, so
we can replace this as no SoC with BMIPS4350 support enabled.

Use the same pattern as with get_*_cpu_type() to allow the compiler
to remove code for non enabled SoC types.

Subject: KVM: PPC: HV: Remove generic instruction emulation

Now that we have properly split load/store instruction emulation and generic
instruction emulation, we can move the generic one from kvm.ko to kvm-pr.ko
on book3s_64.

This reduces the attack surface and amount of code loaded on HV KVM kernels.

Subject: MIPS: BCM63xx: Replace irq dispatch code with a generic version

The generic version uses a variable length of u32 registers instead of u32/u64.
This allows easier support for "wider" registers without having to rewrite
everything.

This "generic" version is as fast as the old version in the best case
(i == next set bit), and twice as fast in the worst case in 64 bits.

Using a macro was chosen over a (forced) inline version because gcc generated
more compact code with the macro.

The change from (signed) int to unsigned int for i and to_call was intentional
as the value can be only between 0 and (width - 1) anyway, and allowed gcc to
optimise the code a bit further.

Subject: MIPS: c-r4k: Avoid duplicate CPU_74K/CPU_1074K checks

Code in a switch statement in probe_pcache checks the CPU type twice
unnecessarily for processor implementations that have the alias removal
feature reported by the CP0 Config7.AR and Config7.IAR bits.  This change
rewrites the affected fragment avoiding the extraneous check and improving
readability.

Subject: MIPS: asm/bitops.h: Guard CLZ with `.set mips32'

This fixes:

{standard input}:920: Error: opcode not supported on this processor: vr5000 (mips4) `clz $7,$9'

{standard input}:4329: Error: opcode not supported on this processor: vr5000 (mips4) `clz $2,$2'
make[2]: *** [arch/mips/mm/tlbex.o] Error 1

which triggered due to a regression causing the file to be built with
`-march=r5000' rather than `-march=sb1', fixed separately.  Nevertheless
the error should not happen, the other uses of CLZ are appropriately
guarded.  This change copies the arrangement from one of those other
places.

Subject: MIPS: SB1: Check optional compilation flags one by one

This fixes a regression caused by commit
bb6c0bd3fdb67c8a1fceea1d4700b9ee593309f9 [MIPS: SB1: Fix excessive kernel
warnings.], that makes `-march=r5000' selected for compilation flags
rather than supposed `-march=sb1' with compilers that do not support the
ASE selection flags introduced with that change.

For example GCC 4.1.2 supports `-mips3d'/`-mno-mips3d' (and obviously
`-march=sb1'), however it does not support `-mdmx'/`-mno-mdmx'.  As a
result the whole selection of flags fails and compilation resorts to using
`-march=r5000', meant for really old compilers indeed only.

It is always best to pick the flags individually unless we are absolutely
sure a set of flags was introduced to the toolchain together (`-march=sb1'
and `-mtune=sb1' would be a good example), and this change makes it happen
for CONFIG_CPU_SB1.  Consequently the flags ultimately selected with GCC
4.1.2 are `-march=sb1 -Wa,--trap -mno-mips3d'

Subject: MIPS: TXx9: Add __init_refok annotation to quirk_slc90e66_bridge

This pci fixup routine calls __init functions.
In general pci fixup routine must not call __init functions,
but this pci/isa bridge device is not hotpluggable anyway.

Subject: MIPS: BCM47XX: make reboot more relaiable

The reboot on the BCM47XX SoCs is done, by setting the watchdog counter
to 1 and let it trigger a reboot, when it reaches 0. Some devices with
a BCM4705/BCM4785 SoC do not reboot when the counter is set to 1 and
decreased to 0 by the hardware. It looks like it works more reliable
when we set it to 3. As far as I understand the hardware, this should
not make any difference, but I do not have access to any documentation
for this SoC.
It is still not 100% reliable.

Subject: MIPS: BCM47XX: fixup broken MAC addresses in nvram

The address prefix 00:90:4C is used by Broadcom in their initial
configuration. When a mac address with the prefix 00:90:4C is used all
devices from the same series are sharing the same mac address. To
prevent mac address collisions we replace them with a mac address based
on the base address. To generate such addresses we take the main mac
address from et0macaddr and increase it by two for the first wifi
device and by 3 for the second one. This matches the printed mac
address on the device. The main mac address increased by one is used as
wan address by the vendor code.

Subject: MIPS: Prevent user from setting FCSR cause bits

If one or more matching FCSR cause & enable bits are set in saved thread
context then when that context is restored the kernel will take an FP
exception. This is of course undesirable and considered an oops, leading
to the kernel writing a backtrace to the console and potentially
rebooting depending upon the configuration. Thus the kernel avoids this
situation by clearing the cause bits of the FCSR register when handling
FP exceptions and after emulating FP instructions.

However the kernel does not prevent userland from setting arbitrary FCSR
cause & enable bits via ptrace, using either the PTRACE_POKEUSR or
PTRACE_SETFPREGS requests. This means userland can trivially cause the
kernel to oops on any system with an FPU. Prevent this from happening
by clearing the cause bits when writing to the saved FCSR context via
ptrace.

This problem appears to exist at least back to the beginning of the git
era in the PTRACE_POKEUSR case.

Subject: MIPS: ftrace: Fix dynamic tracing of kernel modules

Dynamic tracing of kernel modules is broken on 32-bit MIPS. When modules
are loaded, the kernel crashes when dynamic tracing is enabled with:
 cd /sys/kernel/debug/tracing
 echo > set_ftrace_filter
 echo function > current_tracer

1) arch/mips/kernel/ftrace.c
When the kernel boots, or when a module is initialized, ftrace_make_nop()
modifies every _mcount call site to eliminate the ftrace overhead.
However, when ftrace is later enabled for a call site, ftrace_make_call()
does not currently restore the _mcount call correctly for module call sites.
Added ftrace_modify_code_2r() and modified ftrace_make_call() to fix this.

2) arch/mips/kernel/mcount.S
_mcount assembly routine is supposed to have the caller's _mcount call site
address in register a0. However, a0 is currently not calculated correctly for
module call sites. a0 should be (ra - 20) or (ra - 24), depending on whether
the kernel was built with KBUILD_MCOUNT_RA_ADDRESS or not.

This fix has been tested on Broadcom BMIPS5000 processor. Dynamic tracing
now works for both built-in functions and module functions.

Subject: MIPS: pm-cps: Prevent use of mips_cps_* without CPS SMP

These symbols will not be defined when CONFIG_MIPS_CPS=n, but although
the CPS_PM_POWER_GATED state will never be used in that case the
compiler doesn't have enough information to figure that out. Add checks
which evaluate to a constant false for CONFIG_MIPS_CPS=n cases in order
to help the compiler out & eliminate the symbol references.

Subject: MIPS: Fix potential build failures using cpu_vpe_id on non-MT

When used in a non-MT kernel, the cpu_vpe_id macro never made use of
its cpuinfo argument. It doesn't actually need to since it is returning
a constant 0. However not using the argument can lead to build failures
if the compiler then notices that a variable used as part of the
argument is unused. Prevent that problem by "using" the argument as far
as the compiler is concerned, whilst still returning 0 as before.

The dma_cache_wback_inv function performs exactly as is required here,
unless the system has coherent I/O in which case it's a no-op. Call the
underlying cache writeback functions directly, which is arguably clearer
anyway given that the code doesn't actually have anything to do with
DMA in a strict sense.

Subject: MIPS: Remove incorrect NULL check in local_flush_tlb_page()

We check that the struct vm_area_struct pointer vma is NULL and then
dereference it a few lines below. The intent was to make sure vma is
not NULL but this is not necessary since the bug pre-dates GIT history
and seem to never have caused a problem. The tlb-4k and tlb-8k versions
of local_flush_tlb_page() don't bother checking if vma is NULL, also
vma is dereferenced before being passed to local_flush_tlb_page(),
thus it is safe to remove this NULL check.

do_ade() is called because the access is unaligned.  If the current
process is preempted at this time, TIF_USEDFPU will be cleard.  So when
the process is scheduled again, BUG_ON(!is_fpu_owner()) is triggered.

This small program can trigger this BUG in a preemptible kernel:

int main (int argc, char *argv[])
{
        double u64[2];

        while (1) {
                asm volatile (
                        ".set push \n\t"
                        ".set noreorder \n\t"
                        "ldc1 $f3, 4(%0) \n\t"
                        ".set pop \n\t"
                        ::"r"(u64):
                );
        }

        return 0;
}

V2: Remove the BUG_ON() unconditionally due to Paul's suggestion.

Subject: MIPS: Support hard limit of cpu count (nr_cpu_ids)

On MIPS currently, only the soft limit of cpu count (maxcpus) has its
effect, this patch enable the hard limit (nr_cpus) as well. Processor
cores which greater than maxcpus and less than nr_cpus can be taken up
via cpu hotplug. The code is borrowed from X86.

Subject: MIPS: Add NUMA support for Loongson-3

Multiple Loongson-3A chips can be interconnected with HT0-bus. This is
a CC-NUMA system that every chip (node) has its own local memory and
cache coherency is maintained by hardware. The 64-bit physical memory
address format is as follows:

0x-0000-YZZZ-ZZZZ-ZZZZ

The high 16 bits should be 0, which means the real physical address
supported by Loongson-3 is 48-bit. The "Y" bits is the base address of
each node, which can be also considered as the node-id. The "Z" bits is
the address offset within a node, which means every node has a 44 bits
address space.

Macros XPHYSADDR and MAX_PHYSMEM_BITS are modified unconditionally,
because many other MIPS CPUs have also extended their address spaces.

Subject: MIPS: Add numa api support

Enable sys_mbind()/sys_get_mempolicy()/sys_set_mempolicy() for O32, N32,
and N64 ABIs. By the way, O32/N32 should use the compat version of
sys_migrate_pages()/sys_move_pages(), so fix that.

Subject: MIPS: Add Loongson-3B support

Loongson-3B is a 8-cores processor. In general it looks like there are
two Loongson-3A integrated in one chip: 8 cores are separated into two
groups (two NUMA node), each node has its own local memory.

Of course there are some differences between one Loongson-3B and two
Loongson-3A. E.g., the base addresses of IPI registers of each node are
not the same; Loongson-3A use ChipConfig register to enable/disable
clock, but Loongson-3B use FreqControl register instead.

There are two revision of Loongson-3B, the first revision is called as
Loongson-3B1000, whose frequency is 1GHz and has a PRid 0x6306, the
second revision is called as Loongson-3B1500, whose frequency is 1.5GHz
and has a PRid 0x6307. Both revisions has a bug that clock cannot be
disabled at runtime, but this will be fixed in future.

Subject: MIPS: Loongson-3: Enable the COP2 usage

Loongson-3 has some specific instructions (MMI/SIMD) in coprocessor 2.
COP2 isn't independent because it share COP1 (FPU)'s registers. This
patch enable the COP2 usage so user-space programs can use the MMI/SIMD
instructions. When COP2 exception happens, we enable both COP1 (FPU)
and COP2, only in this way the fp context can be saved and restored
correctly.

Subject: MIPS: Loongson: Rename CONFIG_LEMOTE_MACH3A to CONFIG_LOONGSON_MACH3X

Since this CONFIG option will be used for both Loongson-3A/3B machines,
and not all Loongson-3 machines are produced by Lemote, we rename
CONFIG_LEMOTE_MACH3A to CONFIG_LOONGSON_MACH3X.

Subject: MIPS: BCM47XX: Select SYS_SUPPORTS_HIGHMEM for BCM47XX_BCMA
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

It seems that bcm47xx can handle only 128 MiB of RAM directly. There
are few devices with 256 MiB, but Broadcom's SDK uses highmem to handle
anything above 128 MiB.

Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This reverts commit d7a887a73dec6c387b02a966a71aac767bbd9ce6.

Function add_temporary_entry is needed by bcm47xx to support highmem. We
need to add a temporary entry to check for amount of RAM.
The only change made in this revert was replacing (ENTER|EXIT)_CRITICAL.

Subject: MIPS: BCM47XX: Detect more then 128 MiB of RAM (HIGHMEM)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

So far BCM47XX can only detect amount of HIGHMEM. It still requires
adding (registering) and well-testing before enabling by default.

Subject: MIPS: ptrace: Avoid smp_processor_id() when retrieving FPU IR

Whenever ptrace attempts to retrieve the FPU implementation register it
accesses it through current_cpu_data, which calls smp_processor_id().
Since the code may execute with preemption enabled, this can trigger
a warning. Fix this by using boot_cpu_data to get the IR instead.

Subject: MIPS: asm/reg.h: Make 32- and 64-bit definitions available at the
 same time

Get rid of the WANT_COMPAT_REG_H test and instead define both the 32-
and 64-bit register offset definitions at the same time with
MIPS{32,64}_ prefixes, then define the existing EF_* names to the
correct definitions for the kernel's bitness.

This patch is a prerequisite of the following bug fix patch.

Subject: MIPS: ptrace: Change GP regset to use correct core dump register
 layout

Commit 6a9c001b7ec3 ("MIPS: Switch ELF core dumper to use regsets.")
switched the core dumper to use regsets, however the GP regset code
simply makes a direct copy of the kernel's pt_regs, which does not
match the original core dump register layout as defined in asm/reg.h.
Furthermore, the definition of pt_regs can vary with certain Kconfig
variables, therefore the GP regset can never be relied upon to return
registers in the same layout.

Therefore, this patch changes the GP regset to match the original core
dump layout. The layout differs for 32- and 64-bit processes, so
separate implementations of the get/set functions are added for the
32- and 64-bit regsets.

Subject: ARM: dts: Turn on USB host vbus on rk3288-evb

There is no phy driver that works on the Rockchip board for either USB
host port yet.  For now just hardcode the vbus signal to be on all the
time which makes both the dwc2 host and the EHCI port work.

Subject: ARM: dts: add rk3288 ehci usb devices

rk3288 has two kind of usb controller; this adds the ehci variant for
host0 and hsic.

At the moment we don't add any phys for these controllers, but the
default settings seem to work OK.

Subject: ARM: debug: Rename Hi3716 to HIX5HD2

Rename Hisilicon HI3716 to HIX5HD2 and add dependency on ARCH_HIX5HD2.

HiX5HD2 is a SoC with dual Cortex A9 cores for STB market, and original
Hi3xxx SoC is for mobile market.

To avoid confusing the two types of SoCs and also because of different
implementation (SMP, IPs integrated and earlycon config), rename Hi3716
to HIX5HD2 and add ARCH_HIX5HD2.

Subject: ARM: config: enable ARCH_HIX5HD2

Since both ARCH_HI3xxx and ARCH_HIX5HD2 are based on Cortex A9 & they're
using similiar kernel features, make them share the hi3xxx_config.

And add it into multi_v7_defconfig too.

Subject: KVM: PPC: PR: Handle FSCR feature deselects

We handle FSCR feature bits (well, TAR only really today) lazily when the guest
starts using them. So when a guest activates the bit and later uses that feature
we enable it for real in hardware.

However, when the guest stops using that bit we don't stop setting it in
hardware. That means we can potentially lose a trap that the guest expects to
happen because it thinks a feature is not active.

This patch adds support to drop TAR when then guest turns it off in FSCR. While
at it it also restricts FSCR access to 64bit systems - 32bit ones don't have it.

Subject: MIPS: GIC: Prevent array overrun

A GIC interrupt which is declared as having a GIC_MAP_TO_NMI_MSK
mapping causes the cpu parameter to gic_setup_intr() to be increased
to 32, causing memory corruption when pcpu_masks[] is written to again
later in the function.

Commit 72c583951526 (arm64: gicv3: Allow GICv3 compilation with
older binutils) changed the way we express the GICv3 system registers,
but couldn't change the occurences used by KVM as the code wasn't
merged yet.

Just fix the accessors.

Subject: x86, apic: Remove x86_32_numa_cpu_node callback

Since commit b5660ba76b41 ("x86, platforms: Remove NUMAQ") removed NUMAQ,
the x86_32_numa_cpu_node() apic callback has been obsolete.  Remove it.

Subject: x86, apic: Replace trampoline physical addresses with defaults

The trampoline_phys_{high,low} members of struct apic are always
initialized to DEFAULT_TRAMPOLINE_PHYS_HIGH and TRAMPOLINE_PHYS_LOW,
respectively.  Hardwire the constants and remove the unneeded members.

Subject: x86, apic: Replace noop_check_apicid_used

noop_check_apicid_used() has the same implementation as
default_check_apicid_used() in the standard header file, so replace the
former with the latter.

According to the comment “restore_es3: applies to 34xx >= ES3.0" in

if the revision of an OMAP34xx is ES3.1.2.

Subject: KVM: s390/mm: Fix page table locking vs. split pmd lock

commit ec66ad66a0de87866be347b5ecc83bd46427f53b (s390/mm: enable
split page table lock for PMD level) activated the split pmd lock
for s390. Turns out that we missed one place: We also have to take
the pmd lock instead of the page table lock when we reallocate the
page tables (==> changing entries in the PMD) during sie enablement.

Subject: arm64: KVM: fix 64bit CP15 VM access for 32bit guests

Commit f0a3eaff71b8 (ARM64: KVM: fix big endian issue in
access_vm_reg for 32bit guest) changed the way we handle CP15
VM accesses, so that all 64bit accesses are done via vcpu_sys_reg.

This looks like a good idea as it solves indianness issues in an
elegant way, except for one small detail: the register index is
doesn't refer to the same array! We end up corrupting some random
data structure instead.

Fix this by reverting to the original code, except for the introduction
of a vcpu_cp15_64_high macro that deals with the endianness thing.

Tested on Juno with 32bit SMP guests.

Subject: s390/mm: implement dirty bits for large segment table entries

The large segment table entry format has block of bits for the
ACC/F values for the large page. These bits are valid only if
another bit (AV bit 0x10000) of the segment table entry is set.
The ACC/F bits do not have a meaning if the AV bit is off.
This allows to put the THP splitting bit, the segment young bit
and the new segment dirty bit into the ACC/F bits as long as
the AV bit stays off. The dirty and young information is only
available if the pmd is large.

The IP_PKTOPTIONS sockopt puts control messages in option_values, these

through the MSG_CMSG_COMPAT flag, we just need to use
compat_sys_getsockopt which sets that flag.

arch/mips/built-in.o: In function `proc_cpuinfo_notifier_init':

Subject: MIPS: bugfix: missed cache flush of TLB refill handler

Commit

    Commit 1d40cfcd3442a53e98468cdb3e6d4d9a568d76cf
    Author: Ralf Baechle <ralf@linux-mips.org>
    Date:   Fri Jul 15 15:23:23 2005 +0000

    Avoid SMP cacheflushes.  This is a minor optimization of startup but
    will also avoid smp_call_function from doing stupid things when called
    from a CPU that is not yet marked online.

missed an appropriate cache flush of TLB refill handler because that time it was
at fixed location CAC_BASE. After years the refill handler in EBASE vector
is not at that location and can be allocated in some another memory and needs
I-cache sync as other TLB exception vectors.

Besides that, the new function - local_flash_icache_range() was introduced
to avoid SMP cacheflushes.

Subject: MIPS: O32/32-bit: Fix bug which can cause incorrect system call
 restarts

On 32-bit/O32, pt_regs has a padding area at the beginning into which the
syscall arguments passed via the user stack are copied. 4 arguments
totalling 16 bytes are copied to offset 16 bytes into this area, however
the area is only 24 bytes long. This means the last 2 arguments overwrite
pt_regs->regs[{0,1}].

If a syscall function returns an error, handle_sys stores the original
syscall number in pt_regs->regs[0] for syscall restart. signal.c checks
whether regs[0] is non-zero, if it is it will check whether the syscall
return value is one of the ERESTART* codes to see if it must be
restarted.

Should a syscall be made that results in a non-zero value being copied
off the user stack into regs[0], and then returns a positive (non-error)
value that matches one of the ERESTART* error codes, this can be mistaken
for requiring a syscall restart.

While the possibility for this to occur has always existed, it is made
much more likely to occur by commit 46e12c07b3b9 ("MIPS: O32 / 32-bit:
Always copy 4 stack arguments."), since now every syscall will copy 4
arguments and overwrite regs[0], rather than just those with 7 or 8
arguments.

Since that commit, booting Debian under a 32-bit MIPS kernel almost
always results in a hang early in boot, due to a wait4 syscall returning
a PID that matches one of the ERESTART* codes, which then causes an
incorrect restart of the syscall.

The problem is fixed by increasing the size of the padding area so that
arguments copied off the stack will not overwrite pt_regs->regs[{0,1}].

Subject: MIPS: O32/32-bit: Remove outdated comment

A comment in the O32/32-bit system call code is incorrect since commit
46e12c07b3b9 ("MIPS: O32 / 32-bit: Always copy 4 stack arguments.").
Remove it.

Subject: MIPS: ptrace: Fix user pt_regs definition, use in ptrace_{get,
 set}regs()

In uapi/asm/ptrace.h, a user version of pt_regs is defined wrapped in
ifndef __KERNEL__. This structure definition does not match anything
used by any kernel API, in particular it does not match the format used
by PTRACE_{GET,SET}REGS.

Therefore, replace the structure definition with one matching what is
used by PTRACE_{GET,SET}REGS. The format used by these is the same for
both 32-bit and 64-bit.

Also, change the implementation of PTRACE_{GET,SET}REGS to use this new
structure definition. The structure is renamed to user_pt_regs when
__KERNEL__ is defined to avoid conflicts with the kernel's own pt_regs.

Subject: MIPS: Remove asm/user.h

The struct user definition in this file is not used anywhere (the ELF
core dumper does not use that format). Therefore, remove the header and
instead enable the asm-generic user.h which is an empty header to
satisfy a few generic headers which still try to include user.h.

Subject: MIPS: asm/reg.h: Move to uapi

This header defines an exported interface (the register layout used in
core dumps and the GP regset accessible with PTRACE_{GET,SET}REGSET),
therefore belongs in uapi.

From 67dca667516529b24f98dd9d1d4e832ff705054b Mon Sep 17 00:00:00 2001
From: James Hogan <james.hogan@imgtec.com>
Date: Fri, 4 Jul 2014 11:08:56 +0100
Subject: MIPS: perf: Allow for more perf events

In mipsxx_pmu_map_raw_event(), set event_id to base_id after the cpu
type conditional code to allow that code to override the base_id to use
more bits from the config and a higher bit for parity.

This will allow cores with up to 512 events between all even/odd
counters (an 8-bit event id) such as P5600 to use bit 8 for parity.

Subject: MIPS: perf: Add hardware events for P5600

Add cases in perf_event_mipsxx.c for CPU_P5600. All the event numbers
listed for proAptiv also apply to P5600, so we use mipsxxcore_event_map2
and mipsxxcore_cache_map2 too, but the P5600 has 8-bit event numbers so
bit 8 (256) of the user ABI config is used for the parity bit (to
specify odd/even counter events).

Subject: MIPS: cpu-info: Change the cpu options variable to unsigned long long

Long integers which are 4 bytes in MIPS32 can't hold new CPU
options anymore, so the type of the 'options' variable is changed
to unsigned long long which allows 32 more cpu options to be defined
for MIPS32

Also, re-arrange the 'options' struct member to avoid potential 4-byte
alignment gap in the middle of the struct.

Subject: MIPS: mm: Use the Hardware Page Table Walker if the core supports it

The Hardware Page Table Walker aims to speed up TLB refill exceptions
by handling them in the hardware level instead of having a software
TLB refill handler. However, a TLB refill exception can still be
thrown in certain cases such as, synchronus exceptions, or address
translation or memory errors during the HTW operation. As a result of
which, HTW must not be considered a complete replacement for the TLB
refill software handler, but rather a fast-path for it.
For HTW to work, the PWBase register must contain the task's page
global directory address so the HTW will kick in on TLB refill
exceptions.

Due to HTW being a separate engine embedded deep in the CPU pipeline,
we need to restart the HTW everytime a PTE changes to avoid HTW
fetching a old entry from the page tables. It's also necessary to
restart the HTW on context switches to prevent it from fetching a
page from the previous process. Finally, since HTW is using the
entryhi register to write the translations to the TLB, it's necessary
to stop the HTW whenever the entryhi changes (eg for tlb probe
perations) and enable it back afterwards.

== Performance ==

The following trivial test was used to measure the performance of the
HTW. Using the same root filesystem, the following command was used
to measure the number of tlb refill handler executions with and
without (using 'nohtw' kernel parameter) HTW support.  The kernel was
modified to use a scratch register as a counter for the TLB refill
exceptions.

find /usr -type f -exec ls -lh {} \;

HTW Enabled:
TLB refill exceptions: 12306

HTW Disabled:

Subject: MIPS: Use dedicated exception handler if CPU supports RI/XI
 exceptions

Use the regular tlb_do_page_fault_0 (no write) handler to handle
the RI and XI exceptions. Also skip the RI/XI validation check
on TLB load handler since it's redundant when the CPU has
unique RI/XI exceptions.

Subject: MIPS: kernel: cpu-probe: Detect unique RI/XI exceptions

Detect if the core supports unique exception codes for the
Read-Inhibit and Execute-Inhibit exceptions and set the
option accordingly. The RI/XI exception support is detected
by setting the 27th bit (IEC) of the PageGrain C0 register
and reading back the value of that register to verify the
bit is enabled.

Subject: MIPS: GIC: Move GIC_NUM_INTRS into platform irq.h

The value of GIC_NUM_INTRS is platform-specific. Using a default value
from gic.h will result in incorrect behaviour on some systems, so
require a suitable definition to be present in the platform's irq.h.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

irq-gic.c:gic_get_int() masks out interrupts from the pending set which
aren’t in the pcpu_mask. Only interrupts marked with GIC_FLAG_IPI were
set in pcpu_mask, meaning that peripheral interrupts also had to be
marked as IPIs. Remove the use of GIC_FLAG_IPI and allow the flags
member of struct gic_intr_map to be zero.

Subject: MIPS: GIC: Prevent array overrun

A GIC interrupt which is declared as having a GIC_MAP_TO_NMI_MSK
mapping causes the cpu parameter to gic_setup_intr() to be increased
to 32, causing memory corruption when pcpu_masks[] is written to again
later in the function.

Subject: MIPS: GIC: Generalise check for pending interrupts

Move most of the functionality of gic_get_int() into a new function
gic_get_int_mask() which takes a bitmask of interrupts in which the
caller is interested, and returns the subset which are pending for the
current CPU.

This allows CP0 IRQ dispatch routines to check only the GIC interrupts
which are routed to a particular CPU interrupt input.

gic_get_int() is reimplemented using gic_get_int_mask() and is retained
for use by any platforms for which gic_get_int() is sufficient.

Subject: MIPS: Malta: Fix dispatching of GIC interrupts

The Malta malta_ipi_irqdispatch() routine now checks only IPI interrupts
when handling IPIs. It could previously call do_IRQ() for non-IPIs, and
also call do_IRQ() with an invalid IRQ number if there were no pending
GIC interrupts when gic_get_int() was called.

The GICBIS macro could update the GIC registers incorrectly, depending
on the data value passed in:

* Bits were only OR'd into the register data, so register fields could
  not be cleared.

* Bits were OR'd into the register data without masking the data to the
  correct field width, corrupting adjacent bits.

Subject: MIPS: preserve scalar FP CSR when switching vector context

Switching the vector context implicitly saves & restores the state of
the aliased scalar FP data registers, however the scalar FP control
& status register is distinct from the MSA control & status register.
In order to allow scalar FP to function correctly in programs using
MSA, the scalar CSR needs to be saved & restored along with the MSA
vector context.

The kernel depends upon MSA never being enabled when the FPU is not, a
condition which is currently violated in a few places (whilst saving
sigcontext, following mips_cpu_save). Catch all the problem cases by
disabling MSA in lose_fpu, after saving context if necessary.

Subject: MIPS: init upper 64b of vector registers when MSA is first used

When a task first makes use of MSA we need to ensure that the upper
64b of the vector registers are set to some value such that no
information can be leaked to it from the previous task to use MSA
context on the CPU. The architecture formerly specified that these
bits would be cleared to 0 when a scalar FP instructions wrote to the
aliased FP registers, which would have implicitly handled this as the
kernel restored scalar FP context. However more recent versions of the
specification now state that the value of the bits in such cases is
unpredictable. Initialise them explictly to be sure, and set all the
bits to 1 rather than 0 for consistency with the least significant
64b.

Subject: MIPS: fix MSA context for tasks which don't use FP first

If a task does not execute scalar FP instructions prior to using MSA
then the flags indicating that the task has live MSA context were not
being set. The upper 64b of each vector register would then be lost
upon the tasks first context switch after using MSA.

Commit d96cc3d1ec5d "MIPS: Add microMIPS MSA support." attempted to use
the value of a macro within an inline asm statement but instead emitted
a comment leading to the cfcmsa & ctcmsa instructions being omitted. Fix
that by passing CFC_MSA_INSN & CTC_MSA_INSN as arguments to the asm
statements.

Subject: MIPS: ensure MSA gets disabled during boot

The kernel relies upon MSA being disabled when a task begins running,
so that it can initialise or restore context in response to the
resulting MSA disabled exception. Previously the state of MSA following
boot was left as it was before the kernel ran, where MSA could
potentially have been enabled. Explicitly disable it during boot to
prevent any problems.

As a nice side effect the code reads a little better too.

Preemption must be disabled throughout the process of enabling the FPU,
enabling MSA & initialising the vector registers. Without doing so it
is possible to lose the FPU or MSA whilst initialising them causing
that initialisation to fail.

Subject: MIPS: 16 byte align MSA vector context

The MSA specification upon first read appears to suggest that it is safe
to perform vector loads & stores with arbitrary alignment. However it
leaves provision for "address-dependent exceptions"... Align the vector
context to a 16 byte boundary to ensure that the kernel cannot cause any
such exceptions.

Note that the fpu field of struct thread_struct was already at a 16 byte
boundary within the struct, the introduction of FPU_ALIGN simply makes
the requirement explicit. The only part of this impacting the generated
kernel binary is ARCH_MIN_TASKALIGN.

Subject: MIPS: consistently clear MSA flags when starting & copying threads

The TIF_MSA_CTX_LIVE flag (indicating that a task has MSA context which
needs to be preserved) was being cleared in start_thread, but the
TIF_USEDMSA flag (indicating that a task has used MSA in this timeslice)
was not. In copy_thread neither flag was cleared, but both need to be.
Without clearing these flags the kernel will proceed to attempt to save
MSA context when the task is context switched out, and if the task had
not used MSA in the meantime then it will fail because MSA or the FPU
are disabled. The end result is typically:

  do_cpu invoked from kernel context![#1]:
  CPU: 0 PID: 99 Comm: sh Not tainted 3.16.0-rc4-00025-g6dc9476-dirty #88

used if CONFIG_MIPS_O32_FP64_SUPPORT is enabled. If it is not & the
kernel is 32bit, there's no point including support for MSA.

Subject: MIPS: mark MSA experimental

In light of the commit 16f77de82f2d (Revert "MIPS: Save/restore MSA
context around signals") the MSA support in the kernel is incomplete.
Until the replacement for the former sigcontext changes is agreed upon
and in tree, mark MSA experimental & disable it by default.

MSA is only implemented by one CPU supported by the kernel, the P5600.
The P5600 is a 32 bit core, and thus MSA can only be used when the
experimental CONFIG_MIPS_O32_FP64_SUPPORT option is enabled. Therefore
MSA is only being used in experimental settings anyway and this change
doesn't actually make any difference beyond clarifying the state of
MSA support.

Add accessor macros for the Memory Accessibility Attribute Registers
(MAARs), the bits contained within the MAARs & the Config5.MRP bit
indicating their presence. The only current use of the MAARs is to
enable speculative accesses to regions of memory. Besides the potential
performance benefits of speculative accesses, they are a requirement
for the P5600 core to handle non-128b-aligned MSA vector loads & stores
rather than generating an address error.

Subject: MIPS: detect presence of MAARs

Detect the presence of MAAR using the MRP bit in Config5, and record
that presence using a CPU option bit. A cpu_has_maar macro will then
allow code to conditionalise upon the presence of MAARs.

Subject: MIPS: Initialise MAARs

Add initialisation for Memory Accessibility Attribute Registers. Generic
code cannot know the platform-specific requirements with regards to
speculative accesses, so it simply calls a platform_maar_init function
which platforms with MAARs are expected to implement by calling the
provided write_maar_pair function & returning the number of MAAR pairs
used. A weak default implementation will simply use no MAAR pairs. Any
present but unused MAAR pairs are then marked invalid, effectively
disabling them.

The end result of this patch is that MAARs are all marked invalid, until
platforms implement the platform_maar_init function.

Subject: x86/apic/vsmp: Make is_vsmp_box() static

Since checkin

411cf9ee2946 x86, vsmp: Remove is_vsmp_box() from apic_is_clustered_box()

... is_vsmp_box() is only used in vsmp_64.c and does not have any
header file declaring it, so make it explicitly static.

Subject: ARM: imx: Remove references to platform_bus in mxc code

The bus devices created to be parents for other peripherals
were using platform_bus as a parent, not being platform
devices themselves. Remove the references, making them
virtual devices instead.

Subject: ARM: 8122/1: smp_scu: enable SCU standby support

With SCU standby enabled, SCU CLK will be turned off when all processors
are in WFI mode.  And the clock will be turned on when any processor
leaves WFI mode.

This behavior should be preferable in terms of power efficiency of
system idle.  So let's set the SCU standby bit to enable the support in
function scu_enable().

Cortex-A9 earlier than r2p0 has no standby bit in SCU, so we need to
skip setting the bit for those.

Subject: ARM: add comments to the early page table remap code

Add further comments to the early page table remap code to explain what
the code is doing, why it is doing it, but more importantly to explain
that the code is not architecturally compliant and is squarely in
"UNPREDICTABLE" behaviour territory.

Add a warning and tainting of the kernel too.

Subject: net: filter: split 'struct sk_filter' into socket and bpf parts

clean up names related to socket filtering and bpf in the following way:
- everything that deals with sockets keeps 'sk_*' prefix
- everything that is pure BPF is changed to 'bpf_*' prefix

split 'struct sk_filter' into
struct sk_filter {
	atomic_t        refcnt;
	struct rcu_head rcu;
	struct bpf_prog *prog;
};
and
struct bpf_prog {
        u32                     jited:1,
                                len:31;
        struct sock_fprog_kern  *orig_prog;
        unsigned int            (*bpf_func)(const struct sk_buff *skb,
                                            const struct bpf_insn *filter);
        union {
                struct sock_filter      insns[0];
                struct bpf_insn         insnsi[0];
                struct work_struct      work;
        };
};
so that 'struct bpf_prog' can be used independent of sockets and cleans up
'unattached' bpf use cases

split SK_RUN_FILTER macro into:
    SK_RUN_FILTER to be used with 'struct sk_filter *' and
    BPF_PROG_RUN to be used with 'struct bpf_prog *'

__sk_filter_release(struct sk_filter *) gains
__bpf_prog_release(struct bpf_prog *) helper function

also perform related renames for the functions that work
with 'struct bpf_prog *', since they're on the same lines:

sk_filter_size -> bpf_prog_size
sk_filter_select_runtime -> bpf_prog_select_runtime
sk_filter_free -> bpf_prog_free
sk_unattached_filter_create -> bpf_prog_create
sk_unattached_filter_destroy -> bpf_prog_destroy
sk_store_orig_filter -> bpf_prog_store_orig_filter
sk_release_orig_filter -> bpf_release_orig_filter
__sk_migrate_filter -> bpf_migrate_filter
__sk_prepare_filter -> bpf_prepare_filter

API for attaching classic BPF to a socket stays the same:
sk_attach_filter(prog, struct sock *)/sk_detach_filter(struct sock *)
and SK_RUN_FILTER(struct sk_filter *, ctx) to execute a program
which is used by sockets, tun, af_packet

API for 'unattached' BPF programs becomes:
bpf_prog_create(struct bpf_prog **)/bpf_prog_destroy(struct bpf_prog *)
and BPF_PROG_RUN(struct bpf_prog *, ctx) to execute a program
which is used by isdn, ppp, team, seccomp, ptp, xt_bpf, cls_bpf, test_bpf

Subject: x86/efi: Fix 3DNow optimization build failure in EFI stub

Building a 32-bit kernel with CONFIG_X86_USE_3DNOW and CONFIG_EFI_STUB
leads to the following build error,

  drivers/firmware/efi/libstub/lib.a(efi-stub-helper.o): In function `efi_relocate_kernel':
  efi-stub-helper.c:(.text+0xda5): undefined reference to `_mmx_memcpy'

This is due to the fact that the EFI boot stub pulls in the 3DNow
optimized versions of the memcpy() prototype from
arch/x86/include/asm/string_32.h, even though the _mmx_memcpy()
implementation isn't available in the EFI stub.

For now, predicate CONFIG_EFI_STUB on !CONFIG_X86_USE_3DNOW. This is
most definitely a temporary fix. A complete solution will involve
selectively including kernel headers/symbols into the early-boot
execution environment of the EFI boot stub, i.e. something analogous to
the way that the _SETUP symbol is used.

Previous attempts have been made to fix this kind of problem, though
none seem to have ever been merged,

  http://lkml.kernel.org/r/20120329104822.GA17233@x1.osrc.amd.com

Clearly, this problem has been around for a long time.

Subject: sparc64: Do not insert non-valid PTEs into the TSB hash table.

The assumption was that update_mmu_cache() (and the equivalent for PMDs) would
only be called when the PTE being installed will be accessible by the user.

This is not true for code paths originating from remove_migration_pte().

There are dire consequences for placing a non-valid PTE into the TSB.  The TLB
miss frramework assumes thatwhen a TSB entry matches we can just load it into
the TLB and return from the TLB miss trap.

So if a non-valid PTE is in there, we will deadlock taking the TLB miss over
and over, never satisfying the miss.

Just exit early from update_mmu_cache() and friends in this situation.

Based upon a report and patch from Christopher Alexander Tobias Schulze.

Subject: sparc64: Guard against flushing openfirmware mappings.

Based almost entirely upon a patch by Christopher Alexander Tobias
Schulze.

In commit db64fe02258f1507e13fe5212a989922323685ce ("mm: rewrite vmap
layer") lazy VMAP tlb flushing was added to the vmalloc layer.  This
causes problems on sparc64.

Sparc64 has two VMAP mapped regions and they are not contiguous with
eachother.  First we have the malloc mapping area, then another
unrelated region, then the vmalloc region.

This "another unrelated region" is where the firmware is mapped.

If the lazy TLB flushing logic in the vmalloc code triggers after
we've had both a module unload and a vfree or similar, it will pass an
address range that goes from somewhere inside the malloc region to
somewhere inside the vmalloc region, and thus covering the
openfirmware area entirely.

The sparc64 kernel learns about openfirmware's dynamic mappings in
this region early in the boot, and then services TLB misses in this
area.  But openfirmware has some locked TLB entries which are not
mentioned in those dynamic mappings and we should thus not disturb
them.

These huge lazy TLB flush ranges causes those openfirmware locked TLB
entries to be removed, resulting in all kinds of problems including
hard hangs and crashes during reboot/reset.

Besides causing problems like this, such huge TLB flush ranges are
also incredibly inefficient.  A plea has been made with the author of
the VMAP lazy TLB flushing code, but for now we'll put a safety guard
into our flush_tlb_kernel_range() implementation.

Since the implementation has become non-trivial, stop defining it as a
macro and instead make it a function in a C source file.

The LDC handshake could have been asynchronously triggered
after ldc_bind() enables the ldc_rx() receive interrupt-handler
(and thus intercepts incoming control packets)
and before vio_port_up() calls ldc_connect(). If that is the case,
ldc_connect() should return 0 and let the state-machine
progress.

This commit is a guesswork, but it seems to make sense to drop this
break, as otherwise the following line is never executed and becomes
dead code. And that following line actually saves the result of
local calculation by the pointer given in function argument. So the
proposed change makes sense if this code in the whole makes sense (but I
am unable to analyze it in the whole).

Subject: powerpc/eeh: Avoid event on passed PE

We must not handle EEH error on devices which are passed to somebody
else. Instead, we expect that the frozen device owner detects an EEH
error and recovers from it.

This avoids EEH error handling on passed through devices so the device
owner gets a chance to handle them.

Subject: powerpc/eeh: sysfs entries lost

The sysfs entries are lost because of commit 2213fb1 ("powerpc/eeh:
Skip eeh sysfs when eeh is disabled"). That commit added condition
to create sysfs entries with EEH_ENABLED, which isn't populated
when trying to create sysfs entries on PowerNV platform during system
boot time. The patch fixes the issue by:

   * Reoder EEH initialization functions so that they're same on
     PowerNV/pSeries.
   * Cache PE's primary bus by PowerNV platform instead of EEH core
     to avoid kernel crash caused by the function reorder. Another
     benefit with this is to avoid one eeh_probe_mode_dev() in EEH
     core.

This silences a section mismatch warning.  early_alloc_pgtable() is
called from map_kernel_page() which cannot be __init, but only when
slab_is_available() returns false which can only happen during early

Subject: powerpc/powernv: Update dev->dma_mask in pci_set_dma_mask() path

powerpc defines various machine-specific routines for handling
pci_set_dma_mask().  The routines for machine "PowerNV" may neglect
to set dev->dma_mask.  This could confuse anyone (e.g. drivers) that
consult dev->dma_mask to find the current mask.  Set the dma_mask in
the PowerNV leaf routine.

Subject: powerpc/pci: Reorder pci bus/bridge unregistration during PHB removal

Commit bcdde7e made __sysfs_remove_dir() recursive and introduced a BUG_ON
during PHB removal while attempting to delete the power managment attribute
group of the bus. This is a result of tearing the bridge and bus devices down
out of order in remove_phb_dynamic. Since, the the bus resides below the bridge
in the sysfs device tree it should be torn down first.

This patch simply moves the device_unregister call for the PHB bridge device
after the device_unregister call for the PHB bus.

Subject: powerpc/eeh: Wrong place to call pci_get_slot()

pci_get_slot() is called with hold of PCI bus semaphore and it's not
safe to be called in interrupt context. However, we possibly checks
EEH error and calls the function in interrupt context. To avoid using
pci_get_slot(), we turn into device tree for fetching location code.
Otherwise, we might run into WARN_ON() as following messages indicate:

Subject: powerpc/powernv: Fix IOMMU table for VFIO dev

On PHB3, PCI devices can bypass IOMMU for DMA access. If we pass
through one PCI device, whose hose driver ever enable the bypass
mode, pdev->dev.archdata.dma_data.iommu_table_base isn't IOMMU
table. However, EEH needs access the IOMMU table when the device
is owned by guest.

The patch fixes pdev->dev.archdata.dma_data.iommu_table when
passing through the device to guest in pnv_pci_ioda2_set_bypass().

Subject: powerpc/eeh: Fetch IOMMU table in reliable way

Function eeh_iommu_group_to_pe() iterates each PCI device to check
the binding IOMMU group with get_iommu_table_base(), which possibly
fetches pdev->dev.archdata.dma_data.dma_offset. It's (0x1 << 59)
for "bypass" cases.

The patch fixes the issue by iterating devices hooked to the IOMMU
group and fetch IOMMU table there.

There are multiple global EEH flags. Almost each flag has its own

accessors so that they look unified:

  eeh_add_flag():   Add EEH flag
  eeh_clear_flag(): Clear EEH flag
  eeh_has_flag():   Check if one specific flag has been set
  eeh_enabled():    Check if EEH functionality has been enabled

Subject: powerpc/eeh: Selectively enable IO for error log

According to the experiment I did, PCI config access is blocked
on P7IOC frozen PE by hardware, but PHB3 doesn't do that. That
means we always get 0xFF's while dumping PCI config space of the
frozen PE on P7IOC. We don't have the problem on PHB3. So we have
to enable I/O prioir to collecting error log. Otherwise, meaningless
0xFF's are always returned.

The patch fixes it by EEH flag (EEH_ENABLE_IO_FOR_LOG), which is
selectively set to indicate the case for: P7IOC on PowerNV platform,
pSeries platform.

is part of the EEH log so that it looks a bit more compact.

Subject: powerpc/eeh: Replace pr_warning() with pr_warn()

pr_warn() is equal to pr_warning(), but the former is a bit more
formal according to commit fc62f2f ("kernel.h: add pr_warn for
symmetry to dev_warn, netdev_warn").

The patch replaces pr_warning() with pr_warn().

Subject: powerpc/eeh: Make diag-data not endian dependent

It's followup of commit ddf0322a ("powerpc/powernv: Fix endianness
problems in EEH"). The patch helps to get non-endian-dependent
diag-data.

Subject: powerpc/eeh: Aux PE data for error log

The patch allows PE (struct eeh_pe) instance to have auxillary data,
whose size is configurable on basis of platform. For PowerNV, the
auxillary data will be used to cache PHB diag-data for that PE
(frozen PE or fenced PHB). In turn, we can retrieve the diag-data
at any later points.

It's useful for the case of VFIO PCI devices where the error log
should be cached, and then be retrieved by the guest at later point.
Also, it can avoid PHB diag-data overwritting if another frozen PE
reported and the previous diag-data isn't fetched by guest.

Subject: powerpc/powernv: Enable M64 aperatus for PHB3

This patch enables M64 aperatus for PHB3.

We already had platform hook (ppc_md.pcibios_window_alignment) to affect
the PCI resource assignment done in PCI core so that each PE's M32 resource
was built on basis of M32 segment size. Similarly, we're using that for
M64 assignment on basis of M64 segment size.

   * We're using last M64 BAR to cover M64 aperatus, and it's shared by all
     256 PEs.
   * We don't support P7IOC yet. However, some function callbacks are added
     to (struct pnv_phb) so that we can reuse them on P7IOC in future.
   * PE, corresponding to PCI bus with large M64 BAR device attached, might
     span multiple M64 segments. We introduce "compound" PE to cover the case.
     The compound PE is a list of PEs and the master PE is used as before.
     The slave PEs are just for MMIO isolation.

Subject: powerpc/powernv: Allow to freeze PE

The patch synchronizes header file with firmware to have new OPAL
API opal_pci_eeh_freeze_set(), which is used to freeze the specified
PE in order to support "compound" PE.

Subject: powerpc/powernv: Split ioda_eeh_get_state()

Function ioda_eeh_get_state() is used to fetch EEH state for PHB
or PE. We're going to support compound PE and the function becomes
more complicated with that. The patch splits the function into two
functions for PHB and PE cases separately to improve readability.

Subject: powerpc/powernv: Handle compound PE

The patch introduces 3 PHB callbacks: compound PE state retrieval,
force freezing and unfreezing compound PE. The PCI config accessors
and PowerNV EEH backend can use them in subsequent patches.

We don't export the capability of compound PE to EEH core, which
helps avoiding more complexity to EEH core.

The patch handles compound PE for EEH backend. If one specific
PE in compound group has been frozen, we enforces to freeze
all PEs in the group. If we're enable DMA or MMIO for one PE
in compound group, DMA or MMIO of all PEs in the group will be
enabled.

Subject: powerpc/powernv: Handle compound PE in config accessors

The PCI config accessors check for PE frozen state and clear it if
EEH isn't functional. The patch handles compound PE in config accessors
if PHB supports it. For consistency, all PEs will be put into frozen
state if any one in compound group gets frozen by hardware.

Subject: powerpc/book3s: Add basic infrastructure to handle HMI in Linux.

Handle Hypervisor Maintenance Interrupt (HMI) in Linux. This patch implements
basic infrastructure to handle HMI in Linux host. The design is to invoke
opal handle hmi in real mode for recovery and set irq_pending when we hit HMI.
During check_irq_replay pull opal hmi event and print hmi info on console.

Subject: powerpc/powernv: Invoke opal call to handle hmi.

When we hit the HMI in Linux, invoke opal call to handle/recover from HMI
errors in real mode and then in virtual mode during check_irq_replay()
invoke opal_poll_events()/opal_do_notifier() to retrieve HMI event from
OPAL and act accordingly.

Now that we are ready to handle HMI interrupt directly in linux, remove
the HMI interrupt registration with firmware.

Subject: powerpc/book3s: handle HMIs for cpus in nap mode.

HMIs are thread specific and can come while thread is in sleep/nap mode.
Hence with SMT=off mode we can receive HMIs on sleeping threads. For
interrupt received in nap mode, cpu wakes up at system reset vector, clears
the interrupt and go back to nap mode again. But HMIs are sticky and they
keep happening until we clear reason bits from HMER. Hence add a special
check for HMI in reset vector (through power7_wakeup_* functions) and
invoke opal call to handle HMI.

Subject: powerpc/book3s: Fix endianess issue for HMI handling on napping cpus.

(NOTE: This patch depends on upstream HMI handling patchset at
 https://lists.ozlabs.org/pipermail/linuxppc-dev/2014-July/119731.html)

The current HMI handling on napping cpus does not take care of endianess
issue. On LE host kernel when we wake up from nap due to HMI interrupt we
would checkstop while jumping into opal call. There is a similar issue in
case of fast sleep wakeup where the code invokes opal_resync_tb opal call
without handling LE issue. This patch fixes that as well.

With this patch applied, HMIs handling on LE host kernel works fine.

Subject: powerpc: Fail remap_4k_pfn() if PFN doesn't fit inside PTE

remap_4k_pfn() silently truncates upper bits of input 4K PFN
if it cannot be contained in PTE. This leads invalid memory mapping and could
result in a system crash when the memory is accessed. This patch fails
remap_4k_pfn() and returns -EINVAL if the input 4K PFN cannot be contained in
PTE.

V3 : Added parentheses to protect 'pfn' and entire macro as suggested by Brian.
V2 : Rewritten to avoid helper function as suggested by Stephen Rothwell.

Subject: powerpc: implement vmemmap_list_free()

This patch implements vmemmap_list_free() for vmemmap_free().

The freed entries will be removed from vmemmap_list, and form a freed list,
with next as the header. The next position in the last allocated page is kept
at the list tail.

When allocation, if there are freed entries left, get it from the freed list;
if no freed entries left, get it like before from the last allocated pages.

With this change, realmode_pfn_to_page() also needs to be changed to walk
all the entries in the vmemmap_list, as the virt_addr of the entries might not
be stored in order anymore.

It helps to reuse the memory when continuous doing memory hot-plug/remove
operations, but didn't reclaim the pages already allocated, so the memory usage
will only increase, but won't exceed the value for the largest memory
configuration.

Subject: powerpc: start loop at section start of start in vmemmap_populated()

vmemmap_populated() checks whether the [start, start + page_size) has valid
pfn numbers, to know whether a vmemmap mapping has been created that includes
this range.

Some range before end might not be checked by this loop:
  sec11start......start11..sec11end/sec12start..end....start12..sec12end
as the above, for start11(section 11), it checks [sec11start, sec11end), and
loop ends as the next start(start12) is bigger than end. However,
[sec11end/sec12start, end) is not checked here.

So before the loop, adjust the start to be the start of the section, so we don't miss ranges like the above.

After we adjust start to be the start of the section, it also means it's
aligned with vmemmap as of the sizeof struct page, so we could use
page_to_pfn directly in the loop.

Subject: powerpc: Reduce scariness of interrupt frames in stack traces

Some people see things like "Exception: 501" in stack traces in dmesg
and assume that means that something has gone badly wrong, when in
fact "Exception: 501" just means a device interrupt was taken.
This changes "Exception" to "interrupt" to make it clearer that we
are just recording the fact of a change in control flow rather than
some error condition.

Some new functions are exposed for use by the IOMMU code but
won't build when CONFIG_IOMMU_API isn't set, so shield them

Subject: KVM: PPC: drop duplicate tracepoint

Commit 29577fc00ba4 ("KVM: PPC: HV: Remove generic instruction emulation")
caused a build failure with allyesconfig:

arch/powerpc/kvm/kvm-pr.o:(__tracepoints+0xa8): multiple definition of `__tracepoint_kvm_ppc_instr'
arch/powerpc/kvm/kvm.o:(__tracepoints+0x1c0): first defined here

due to a duplicate definition of the tracepoint in trace.h and
trace_pr.h.  Because the tracepoint is still used by Book3S HV
code, and because the PR code does include trace.h, just remove
the duplicate definition from trace_pr.h, and export it from
kvm.o.

Subject: KVM: irqchip: Provide and use accessors for irq routing table

This provides accessor functions for the KVM interrupt mappings, in
order to reduce the amount of code that accesses the fields of the
kvm_irq_routing_table struct, and restrict that code to one file,
virt/kvm/irqchip.c.  The new functions are kvm_irq_map_gsi(), which
maps from a global interrupt number to a set of IRQ routing entries,
and kvm_irq_map_chip_pin, which maps from IRQ chip and pin numbers to
a global interrupt number.

This also moves the update of kvm_irq_routing_table::chip[][]
into irqchip.c, out of the various kvm_set_routing_entry
implementations.  That means that none of the kvm_set_routing_entry
implementations need the kvm_irq_routing_table argument anymore,
so this removes it.

This does not change any locking or data lifetime rules.

Subject: KVM: Give IRQFD its own separate enabling Kconfig option

Currently, the IRQFD code is conditional on CONFIG_HAVE_KVM_IRQ_ROUTING.
So that we can have the IRQFD code compiled in without having the
IRQ routing code, this creates a new CONFIG_HAVE_KVM_IRQFD, makes
the IRQFD code conditional on it instead of CONFIG_HAVE_KVM_IRQ_ROUTING,
and makes all the platforms that currently select HAVE_KVM_IRQ_ROUTING
also select HAVE_KVM_IRQFD.

Subject: KVM: PPC: Enable IRQFD support for the XICS interrupt controller

This makes it possible to use IRQFDs on platforms that use the XICS
interrupt controller.  To do this we implement kvm_irq_map_gsi() and
kvm_irq_map_chip_pin() in book3s_xics.c, so as to provide a 1-1 mapping
between global interrupt numbers and XICS interrupt source numbers.
For now, all interrupts are mapped as "IRQCHIP" interrupts, and no
MSI support is provided.

This means that kvm_set_irq can now get called with level == 0 or 1
as well as the powerpc-specific values KVM_INTERRUPT_SET,
KVM_INTERRUPT_UNSET and KVM_INTERRUPT_SET_LEVEL.  We change
ics_deliver_irq() to accept all those values, and remove its
report_status argument, as it is always false, given that we don't
support KVM_IRQ_LINE_STATUS.

This also adds support for interrupt ack notifiers to the XICS code
so that the IRQFD resampler functionality can be supported.

Subject: KVM: nVMX: Fix nested vmexit ack intr before load vmcs01

An external interrupt will cause a vmexit with reason "external interrupt"
when L2 is running.  L1 will pick up the interrupt through vmcs12 if
L1 set the ack interrupt bit.  Commit 77b0f5d (KVM: nVMX: Ack and write
vector info to intr_info if L1 asks us to) retrieves the interrupt that
belongs to L1 before vmcs01 is loaded.

This will lead to problems in the next patch, which would write to SVI
of vmcs02 instead of vmcs01 (SVI of vmcs02 doesn't make sense because
L2 runs without APICv).

Subject: KVM: nVMX: fix "acknowledge interrupt on exit" when APICv is in use

After commit 77b0f5d (KVM: nVMX: Ack and write vector info to intr_info
if L1 asks us to), "Acknowledge interrupt on exit" behavior can be
emulated. To do so, KVM will ask the APIC for the interrupt vector if
during a nested vmexit if VM_EXIT_ACK_INTR_ON_EXIT is set.  With APICv,
kvm_get_apic_interrupt would return -1 and give the following WARNING:

Call Trace:
 [<ffffffff81493563>] dump_stack+0x49/0x5e
 [<ffffffff8103f0eb>] warn_slowpath_common+0x7c/0x96

 [<ffffffffa051ebe9>] inject_pending_event+0xd0/0x16e [kvm]
 [<ffffffffa051efa0>] vcpu_enter_guest+0x319/0x704 [kvm]

To fix this, we cannot rely on the processor's virtual interrupt delivery,
because "acknowledge interrupt on exit" must only update the virtual
ISR/PPR/IRR registers (and SVI, which is just a cache of the virtual ISR)
but it should not deliver the interrupt through the IDT.  Thus, KVM has
to deliver the interrupt "by hand", similar to the treatment of EOI in
commit fc57ac2c9ca8 (KVM: lapic: sync highest ISR to hardware apic on
EOI, 2014-05-14).

The patch modifies kvm_cpu_get_interrupt to always acknowledge an
interrupt; there are only two callers, and the other is not affected
because it is never reached with kvm_apic_vid_enabled() == true.  Then it
modifies apic_set_isr and apic_clear_irr to update SVI and RVI in addition
to the registers.

Subject: random: introduce getrandom(2) system call

The getrandom(2) system call was requested by the LibreSSL Portable
developers.  It is analoguous to the getentropy(2) system call in
OpenBSD.

The rationale of this system call is to provide resiliance against
file descriptor exhaustion attacks, where the attacker consumes all
available file descriptors, forcing the use of the fallback code where
/dev/[u]random is not available.  Since the fallback code is often not
well-tested, it is better to eliminate this potential failure mode
entirely.

The other feature provided by this new system call is the ability to
request randomness from the /dev/urandom entropy pool, but to block
until at least 128 bits of entropy has been accumulated in the
/dev/urandom entropy pool.  Historically, the emphasis in the
/dev/urandom development has been to ensure that urandom pool is
initialized as quickly as possible after system boot, and preferably
before the init scripts start execution.

This is because changing /dev/urandom reads to block represents an
interface change that could potentially break userspace which is not
acceptable.  In practice, on most x86 desktop and server systems, in
general the entropy pool can be initialized before it is needed (and
in modern kernels, we will printk a warning message if not).  However,
on an embedded system, this may not be the case.  And so with this new
interface, we can provide the functionality of blocking until the
urandom pool has been initialized.  Any userspace program which uses
this new functionality must take care to assure that if it is used
during the boot process, that it will not cause the init scripts or
other portions of the system startup to hang indefinitely.

SYNOPSIS
	#include <linux/random.h>

	int getrandom(void *buf, size_t buflen, unsigned int flags);

DESCRIPTION
	The system call getrandom() fills the buffer pointed to by buf
	with up to buflen random bytes which can be used to seed user
	space random number generators (i.e., DRBG's) or for other
	cryptographic uses.  It should not be used for Monte Carlo
	simulations or other programs/algorithms which are doing
	probabilistic sampling.

	If the GRND_RANDOM flags bit is set, then draw from the
	/dev/random pool instead of the /dev/urandom pool.  The
	/dev/random pool is limited based on the entropy that can be
	obtained from environmental noise, so if there is insufficient
	entropy, the requested number of bytes may not be returned.
	If there is no entropy available at all, getrandom(2) will
	either block, or return an error with errno set to EAGAIN if
	the GRND_NONBLOCK bit is set in flags.

	If the GRND_RANDOM bit is not set, then the /dev/urandom pool
	will be used.  Unlike using read(2) to fetch data from
	/dev/urandom, if the urandom pool has not been sufficiently
	initialized, getrandom(2) will block (or return -1 with the
	errno set to EAGAIN if the GRND_NONBLOCK bit is set in flags).

	The getentropy(2) system call in OpenBSD can be emulated using
	the following function:

            int getentropy(void *buf, size_t buflen)
            {
                    int     ret;

                    if (buflen > 256)
                            goto failure;
                    ret = getrandom(buf, buflen, 0);
                    if (ret < 0)
                            return ret;
                    if (ret == buflen)
                            return 0;
            failure:
                    errno = EIO;
                    return -1;
            }

RETURN VALUE
       On success, the number of bytes that was filled in the buf is
       returned.  This may not be all the bytes requested by the
       caller via buflen if insufficient entropy was present in the
       /dev/random pool, or if the system call was interrupted by a
       signal.

       On error, -1 is returned, and errno is set appropriately.

ERRORS
	EINVAL		An invalid flag was passed to getrandom(2)

	EFAULT		buf is outside the accessible address space.

	EAGAIN		The requested entropy was not available, and
			getentropy(2) would have blocked if the
			GRND_NONBLOCK flag was not set.

	EINTR		While blocked waiting for entropy, the call was
			interrupted by a signal handler; see the description
			of how interrupted read(2) calls on "slow" devices
			are handled with and without the SA_RESTART flag
			in the signal(7) man page.

NOTES
	For small requests (buflen <= 256) getrandom(2) will not
	return EINTR when reading from the urandom pool once the
	entropy pool has been initialized, and it will return all of
	the bytes that have been requested.  This is the recommended
	way to use getrandom(2), and is designed for compatibility
	with OpenBSD's getentropy() system call.

	However, if you are using GRND_RANDOM, then getrandom(2) may
	block until the entropy accounting determines that sufficient
	environmental noise has been gathered such that getrandom(2)
	will be operating as a NRBG instead of a DRBG for those people
	who are working in the NIST SP 800-90 regime.  Since it may
	block for a long time, these guarantees do *not* apply.  The
	user may want to interrupt a hanging process using a signal,
	so blocking until all of the requested bytes are returned
	would be unfriendly.

	For this reason, the user of getrandom(2) MUST always check
	the return value, in case it returns some error, or if fewer
	bytes than requested was returned.  In the case of
	!GRND_RANDOM and small request, the latter should never
	happen, but the careful userspace code (and all crypto code
	should be careful) should check for this anyway!

	Finally, unless you are doing long-term key generation (and
	perhaps not even then), you probably shouldn't be using
	GRND_RANDOM.  The cryptographic algorithms used for
	/dev/urandom are quite conservative, and so should be
	sufficient for all purposes.  The disadvantage of GRND_RANDOM
	is that it can block, and the increased complexity required to
	deal with partially fulfilled getrandom(2) requests.

Subject: x86/efi: Enforce CONFIG_RELOCATABLE for EFI boot stub
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Without CONFIG_RELOCATABLE the early boot code will decompress the
kernel to LOAD_PHYSICAL_ADDR. While this may have been fine in the BIOS
days, that isn't going to fly with UEFI since parts of the firmware
code/data may be located at LOAD_PHYSICAL_ADDR.

Straying outside of the bounds of the regions we've explicitly requested
from the firmware will cause all sorts of trouble. Bruno reports that
his machine resets while trying to decompress the kernel image.

We already go to great pains to ensure the kernel is loaded into a
suitably aligned buffer, it's just that the address isn't necessarily
LOAD_PHYSICAL_ADDR, because we can't guarantee that address isn't in-use
by the firmware.

Explicitly enforce CONFIG_RELOCATABLE for the EFI boot stub, so that we
can load the kernel at any address with the correct alignment.

Subject: x86: MCE: Add raw_lock conversion again

Commit ea431643d6c3 ("x86/mce: Fix CMCI preemption bugs") breaks RT by
the completely unrelated conversion of the cmci_discover_lock to a
regular (non raw) spinlock.  This lock was annotated in commit
59d958d2c7de ("locking, x86: mce: Annotate cmci_discover_lock as raw")
with a proper explanation why.

The argument for converting the lock back to a regular spinlock was:

 - it does percpu ops without disabling preemption. Preemption is not
   disabled due to the mistaken use of a raw spinlock.

Which is complete nonsense.  The raw_spinlock is disabling preemption in
the same way as a regular spinlock.  In mainline spinlock maps to
raw_spinlock, in RT spinlock becomes a "sleeping" lock.

raw_spinlock has on RT exactly the same semantics as in mainline.  And
because this lock is taken in non preemptible context it must be raw on
RT.

Undo the locking brainfart.

Subject: ia64: Use get_signal() signal_setup_done()

Use the more generic functions get_signal() signal_setup_done()

This inverts also the return codes of force_sigsegv_info()

Subject: powerpc: Use get_signal() signal_setup_done()

Use the more generic functions get_signal() signal_setup_done()
for signal delivery.
This inverts also the return codes of setup_*frame() to follow the
kernel convention.

'COUNTER' and other same kind macros are too common to use, and easy to

At present, they are not used, so it is OK to simply remove them.  And

Fix build error as reported by Geert Uytterhoeven here:

The error happens when CONFIG_HAS_IOPORT_MAP=n because of which there
are missing definitions of ioport_map/unmap().  Fix this build error by
adding these prototypes.

Subject: CMA: generalize CMA reserved area management functionality

Currently, there are two users on CMA functionality, one is the DMA
subsystem and the other is the KVM on powerpc.  They have their own code
to manage CMA reserved area even if they looks really similar.  From my
guess, it is caused by some needs on bitmap management.  KVM side wants
to maintain bitmap not for 1 page, but for more size.  Eventually it use
bitmap where one bit represents 64 pages.

When I implement CMA related patches, I should change those two places
to apply my change and it seem to be painful to me.  I want to change
this situation and reduce future code management overhead through this
patch.

This change could also help developer who want to use CMA in their new
feature development, since they can use CMA easily without copying &
pasting this reserved area management code.

In previous patches, we have prepared some features to generalize CMA
reserved area management and now it's time to do it.  This patch moves
core functions to mm/cma.c and change DMA APIs to use these functions.

There is no functional change in DMA APIs.

Subject: mm, CMA: change cma_declare_contiguous() to obey coding convention

Conventionally, we put output param to the end of param list and put the
'base' ahead of 'size', but cma_declare_contiguous() doesn't look like
that, so change it.

Additionally, move down cma_areas reference code to the position where
it is really needed.

From: WANG Chao <chaowang@redhat.com>

Subject: mm/vmalloc.c: clean up map_vm_area third argument

Currently map_vm_area() takes (struct page *** pages) as third argument,
and after mapping, it moves (*pages) to point to (*pages +
nr_mappped_pages).

It looks like this kind of increment is useless to its caller these
days.  The callers don't care about the increments and actually they're
trying to avoid this by passing another copy to map_vm_area().

The caller can always guarantee all the pages can be mapped into vm_area
as specified in first argument and the caller only cares about whether
map_vm_area() fails or not.

This patch cleans up the pointer movement in map_vm_area() and updates
its callers accordingly.

Subject: mm: describe mmap_sem rules for __lock_page_or_retry() and callers

Add a comment describing the circumstances in which
__lock_page_or_retry() will or will not release the mmap_sem when
returning 0.

Add comments to lock_page_or_retry()'s callers (filemap_fault(),
do_swap_page()) noting the impact on VM_FAULT_RETRY returns.

Add comments on up the call tree, particularly replacing the false "We
return with mmap_sem still held" comments.

Subject: ARM64: add IPI tracepoints

The strings used to list IPIs in /proc/interrupts are reused for tracing
purposes.

While at it, the code is slightly cleaned up so the ipi_types array
indices are no longer offset by IPI_RESCHEDULE whose value is 0 anyway.

Subject: x86, irq, PCI: Keep IRQ assignment for PCI devices during
 suspend/hibernation

Now IOAPIC driver dynamically allocates IRQ numbers for IOAPIC pins.
We need to keep IRQ assignment for PCI devices during suspend/hibernation,
otherwise it may cause failure of suspend/hibernation due to:
1) Device driver calls pci_enable_device() to allocate an IRQ number
   and register interrupt handler on the returned IRQ.
2) Device driver's suspend callback calls pci_disable_device() and
   release assigned IRQ in turn.
3) Device driver's resume callback calls pci_enable_device() to
   allocate IRQ number again. A different IRQ number may be assigned
   by IOAPIC driver this time.
4) Now the hardware delivers interrupt to the new IRQ but interrupt
   handler is still registered against the old IRQ, so it breaks
   suspend/hibernation.

To fix this issue, we keep IRQ assignment during suspend/hibernation.
Flag pci_dev.dev.power.is_prepared is used to detect that
pci_disable_device() is called during suspend/hibernation.

Subject: rtc: ia64: allow other architectures to use EFI RTC

Currently, the rtc-efi driver is restricted to ia64 only.  Newer
architectures with EFI support may want to also use that driver.  This
patch moves the platform device setup from ia64 into drivers/rtc and
allow any architecture with CONFIG_EFI=y to use the rtc-efi driver.

From 56106da7932074804f9ef70191f126ea15dc3fc4 Mon Sep 17 00:00:00 2001
From: Laura Abbott <lauraa@codeaurora.org>
Date: Fri, 8 Aug 2014 14:23:27 -0700
Subject: lib/scatterlist: clean up useless architecture versions of
 scatterlist.h

There's no need to have an architecture version of scatterlist.h if the
only thing the file does is include asm-generic/scatterlist.h.  Switch to
the asm-generic versions directly.

From a6c19dfe39941a5d3f4d072121c0a4841e7e26fd Mon Sep 17 00:00:00 2001
From: Andy Lutomirski <luto@amacapital.net>
Date: Fri, 8 Aug 2014 14:23:40 -0700
Subject: arm64,ia64,ppc,s390,sh,tile,um,x86,mm: remove default gate area

The core mm code will provide a default gate area based on
FIXADDR_USER_START and FIXADDR_USER_END if
!defined(__HAVE_ARCH_GATE_AREA) && defined(AT_SYSINFO_EHDR).

This default is only useful for ia64.  arm64, ppc, s390, sh, tile, 64-bit
UML, and x86_32 have their own code just to disable it.  arm, 32-bit UML,
and x86_64 have gate areas, but they have their own implementations.

This gets rid of the default and moves the code into ia64.

This should save some code on architectures without a gate area: it's now
possible to inline the gate_area functions in the default case.

Subject: shm: add memfd_create() syscall

memfd_create() is similar to mmap(MAP_ANON), but returns a file-descriptor
that you can pass to mmap().  It can support sealing and avoids any
connection to user-visible mount-points.  Thus, it's not subject to quotas
on mounted file-systems, but can be used like malloc()'ed memory, but with
a file-descriptor to it.

memfd_create() returns the raw shmem file, so calls like ftruncate() can
be used to modify the underlying inode.  Also calls like fstat() will
return proper information and mark the file as regular file.  If you want
sealing, you can specify MFD_ALLOW_SEALING.  Otherwise, sealing is not
supported (like on all other regular files).

Compared to O_TMPFILE, it does not require a tmpfs mount-point and is not
subject to a filesystem size limit.  It is still properly accounted to
memcg limits, though, and to the same overcommit or no-overcommit
accounting as all user memory.

Subject: kernel: build bin2c based on config option CONFIG_BUILD_BIN2C

currently bin2c builds only if CONFIG_IKCONFIG=y. But bin2c will now be
used by kexec too.  So make it compilation dependent on CONFIG_BUILD_BIN2C
and this config option can be selected by CONFIG_KEXEC and CONFIG_IKCONFIG.

Subject: kexec: new syscall kexec_file_load() declaration

This is the new syscall kexec_file_load() declaration/interface.  I have
reserved the syscall number only for x86_64 so far.  Other architectures
(including i386) can reserve syscall number when they enable the support
for this new syscall.

Subject: kexec: implementation of new syscall kexec_file_load

Previous patch provided the interface definition and this patch prvides
implementation of new syscall.

Previously segment list was prepared in user space.  Now user space just
passes kernel fd, initrd fd and command line and kernel will create a
segment list internally.

This patch contains generic part of the code.  Actual segment preparation
and loading is done by arch and image specific loader.  Which comes in
next patch.

Subject: purgatory/sha256: provide implementation of sha256 in purgaotory
 context

Next two patches provide code for purgatory.  This is a code which does
not link against the kernel and runs stand alone.  This code runs between
two kernels.  One of the primary purpose of this code is to verify the
digest of newly loaded kernel and making sure it matches the digest
computed at kernel load time.

We use sha256 for calculating digest of kexec segmetns.  Purgatory can't
use stanard crypto API as that API is not available in purgatory context.

Hence, I have copied code from crypto/sha256_generic.c and compiled it
with purgaotry code so that it could be used.  I could not #include
sha256_generic.c file here as some of the function signature requiered
little tweaking.  Original functions work with crypto API but these ones
don't

So instead of doing #include on sha256_generic.c I just copied relevant
portions of code into arch/x86/purgatory/sha256.c.  Now we shouldn't have
to touch this code at all.  Do let me know if there are better ways to
handle it.

This patch does not enable compiling of this code.  That happens in next
patch.  I wanted to highlight this change in a separate patch for easy
review.

From 8fc5b4d4121c95482b2583a07863c6b0aba2d9e1 Mon Sep 17 00:00:00 2001

Subject: purgatory: core purgatory functionality

Create a stand alone relocatable object purgatory which runs between two
kernels.  This name, concept and some code has been taken from
kexec-tools.  Idea is that this code runs after a crash and it runs in
minimal environment.  So keep it separate from rest of the kernel and in
long term we will have to practically do no maintenance of this code.

This code also has the logic to do verify sha256 hashes of various
segments which have been loaded into memory.  So first we verify that the
kernel we are jumping to is fine and has not been corrupted and make
progress only if checsums are verified.

This code also takes care of copying some memory contents to backup region.

From 12db5562e0352986a265841638482b84f3a6899b Mon Sep 17 00:00:00 2001
From: Vivek Goyal <vgoyal@redhat.com>
Date: Fri, 8 Aug 2014 14:26:04 -0700
Subject: kexec: load and relocate purgatory at kernel load time

Load purgatory code in RAM and relocate it based on the location.
Relocation code has been inspired by module relocation code and purgatory
relocation code in kexec-tools.

Also compute the checksums of loaded kexec segments and store them in
purgatory.

Arch independent code provides this functionality so that arch dependent
bootloaders can make use of it.

Helper functions are provided to get/set symbol values in purgatory which
are used by bootloaders later to set things like stack and entry point of
second kernel etc.

Subject: kexec-bzImage64: support for loading bzImage using 64bit entry

This is loader specific code which can load bzImage and set it up for
64bit entry.  This does not take care of 32bit entry or real mode entry.

32bit mode entry can be implemented if somebody needs it.

This patch adds support for loading a kexec on panic (kdump) kernel usning
new system call.

It prepares ELF headers for memory areas to be dumped and for saved cpu
registers.  Also prepares the memory map for second kernel and limits its
boot to reserved areas only.

From 6a2c20e7d8900ed273dc34a9af9bf02fc478e427 Mon Sep 17 00:00:00 2001
From: Vivek Goyal <vgoyal@redhat.com>
Date: Fri, 8 Aug 2014 14:26:11 -0700
Subject: kexec: support kexec/kdump on EFI systems

This patch does two things.  It passes EFI run time mappings to second
kernel in bootparams efi_info.  Second kernel parse this info and create
new mappings in second kernel.  That means mappings in first and second
kernel will be same.  This paves the way to enable EFI in kexec kernel.

This patch also prepares and passes EFI setup data through bootparams.
This contains bunch of information about various tables and their
addresses.

These information gathering and passing has been written along the lines
of what current kexec-tools is doing to make kexec work with UEFI.

From 8e7d838103feac320baf9e68d73f954840ac1eea Mon Sep 17 00:00:00 2001
From: Vivek Goyal <vgoyal@redhat.com>

Subject: kexec: verify the signature of signed PE bzImage

This is the final piece of the puzzle of verifying kernel image signature
during kexec_file_load() syscall.

This patch calls into PE file routines to verify signature of bzImage.  If
signature are valid, kexec_file_load() succeeds otherwise it fails.

Two new config options have been introduced.  First one is
CONFIG_KEXEC_VERIFY_SIG.  This option enforces that kernel has to be
validly signed otherwise kernel load will fail.  If this option is not
set, no signature verification will be done.  Only exception will be when
secureboot is enabled.  In that case signature verification should be
automatically enforced when secureboot is enabled.  But that will happen
when secureboot patches are merged.

Second config option is CONFIG_KEXEC_BZIMAGE_VERIFY_SIG.  This option
enables signature verification support on bzImage.  If this option is not
set and previous one is set, kernel image loading will fail because kernel
does not have support to verify signature of bzImage.

I tested these patches with both "pesign" and "sbsign" signed bzImages.

I used signing_key.priv key and signing_key.x509 cert for signing as
generated during kernel build process (if module signing is enabled).

Used following method to sign bzImage.

pesign
======
- Convert DER format cert to PEM format cert
openssl x509 -in signing_key.x509 -inform DER -out signing_key.x509.PEM -outform
PEM

- Generate a .p12 file from existing cert and private key file
openssl pkcs12 -export -out kernel-key.p12 -inkey signing_key.priv -in
signing_key.x509.PEM

- Import .p12 file into pesign db
pk12util -i /tmp/kernel-key.p12 -d /etc/pki/pesign

- Sign bzImage
pesign -i /boot/vmlinuz-3.16.0-rc3+ -o /boot/vmlinuz-3.16.0-rc3+.signed.pesign
-c "Glacier signing key - Magrathea" -s

sbsign
======
sbsign --key signing_key.priv --cert signing_key.x509.PEM --output
/boot/vmlinuz-3.16.0-rc3+.signed.sbsign /boot/vmlinuz-3.16.0-rc3+

Patch details:

Well all the hard work is done in previous patches.  Now bzImage loader
has just call into that code and verify whether bzImage signature are
valid or not.

Also create two config options.  First one is CONFIG_KEXEC_VERIFY_SIG.
This option enforces that kernel has to be validly signed otherwise kernel
load will fail.  If this option is not set, no signature verification will
be done.  Only exception will be when secureboot is enabled.  In that case
signature verification should be automatically enforced when secureboot is
enabled.  But that will happen when secureboot patches are merged.

Second config option is CONFIG_KEXEC_BZIMAGE_VERIFY_SIG.  This option
enables signature verification support on bzImage.  If this option is not
set and previous one is set, kernel image loading will fail because kernel
does not have support to verify signature of bzImage.

Subject: ARM: 8114/1: LPAE: load upper bits of early TTBR0/TTBR1

This patch fixes booting when idmap pgd lays above 4gb. Commit
4756dcbfd37 mostly had fixed this, but it'd failed to load upper bits.

Also this fixes adding TTBR1_OFFSET to TTRR1: if lower part overflows
carry flag must be added to the upper part.

Subject: ARM: EXYNOS: Fix suspend/resume sequences

Due to recent consolidation of Exynos suspend and cpuidle code, some
parts of suspend and resume sequences are executed two times, once from
exynos_pm_syscore_ops and then from exynos_cpu_pm_notifier() and thus it
breaks suspend, at least on Exynos4-based boards. In addition, simple
core power down from a cpuidle driver could, in case of CPU 0 could
result in calling functions that are specific to suspend and deeper idle
states.

This patch fixes the issue by moving those operations outside the CPU PM
notifier into suspend and AFTR code paths. This leads to a bit of code
duplication, but allows additional code simplification, so in the end
more code is removed than added.

Fixes: 85f9f90808b4 ("ARM: EXYNOS: Use the cpu_pm notifier for pm")

This was caused by commit 5a8da524049c ("ARM: dts: exynos5420: add dsi
node"), which conflicted with d51cad7df871 ("ARM: dts: remove display
power domain for exynos5420").

The DTS addition should never have been merged through the DRM tree in
the first place, and it lacked an ack from the platform maintainer
(who would have known that the disp_pd reference got removed).

Subject: x86/xen: resume timer irqs early

If the timer irqs are resumed during device resume it is possible in
certain circumstances for the resume to hang early on, before device
interrupts are resumed.  For an Ubuntu 14.04 PVHVM guest this would
occur in ~0.5% of resume attempts.

It is not entirely clear what is occuring the point of the hang but I
think a task necessary for the resume calls schedule_timeout(),
waiting for a timer interrupt (which never arrives).  This failure may
require specific tasks to be running on the other VCPUs to trigger
(processes are not frozen during a suspend/resume if PREEMPT is
disabled).

Add IRQF_EARLY_RESUME to the timer interrupts so they are resumed in
syscore_resume().

Subject: x86/xen: use vmap() to map grant table pages in PVH guests

Commit b7dd0e350e0b (x86/xen: safely map and unmap grant frames when
in atomic context) causes PVH guests to crash in
arch_gnttab_map_shared() when they attempted to map the pages for the
grant table.

This use of a PV-specific function during the PVH grant table setup is
non-obvious and not needed.  The standard vmap() function does the
right thing.

Subject: sparc64: Do not disable interrupts in nmi_cpu_busy()

nmi_cpu_busy() is a SMP function call that just makes sure that all of the
cpus are spinning using cpu cycles while the NMI test runs.

It does not need to disable IRQs because we just care about NMIs executing
which will even with 'normal' IRQs disabled.

It is not legal to enable hard IRQs in a SMP cross call, in fact this bug
triggers the BUG check in irq_work_run_list():

	BUG_ON(!irqs_disabled());

Because now irq_work_run() is invoked from the tail of
generic_smp_call_function_single_interrupt().

Subject: sparc64: Fix pcr_ops initialization and usage bugs.

Christopher reports that perf_event_print_debug() can crash in uniprocessor
builds.  The crash is due to pcr_ops being NULL.

This happens because pcr_arch_init() is only invoked by smp_cpus_done() which
only executes in SMP builds.

init_hw_perf_events() is closely intertwined with pcr_ops being setup properly,
therefore:

1) Call pcr_arch_init() early on from init_hw_perf_events(), instead of
   from smp_cpus_done().

2) Do not hook up a PMU type if pcr_ops is NULL after pcr_arch_init().

3) Move init_hw_perf_events to a later initcall so that it we will be
   sure to invoke pcr_arch_init() after all cpus are brought up.

Finally, guard the one naked sequence of pcr_ops dereferences in
__global_pmu_self() with an appropriate NULL check.

Subject: PCI: Remove DEFINE_PCI_DEVICE_TABLE macro use

We should prefer `struct pci_device_id` over `DEFINE_PCI_DEVICE_TABLE` to
meet kernel coding style guidelines.  This issue was reported by checkpatch.

A simplified version of the semantic patch that makes this change is as
follows (http://coccinelle.lip6.fr/):

// <smpl>

@@
identifier i;
declarer name DEFINE_PCI_DEVICE_TABLE;
initializer z;
@@

- DEFINE_PCI_DEVICE_TABLE(i)
+ const struct pci_device_id i[]
= z;

From 5d61a2172a0142c635ab6d7c3b1589af85a3603e Mon Sep 17 00:00:00 2001
From: Scott Wood <scottwood@freescale.com>
Date: Fri, 8 Aug 2014 18:44:01 -0500
Subject: powerpc/nohash: Split __early_init_mmu() into boot and secondary

__early_init_mmu() does some things that are really only needed by the
boot cpu.  On FSL booke, This includes calling
memblock_enforce_memory_limit(), which is labelled __init.  Secondary
cpu init code can't be __init as that would break CPU hotplug.

While it's probably a bug that memblock_enforce_memory_limit() isn't
__init_memblock instead, there's no reason why we should be doing this
stuff for secondary cpus in the first place.

Subject: powerpc: Fix "attempt to move .org backwards" error

Once again, we see

arch/powerpc/kernel/exceptions-64s.S: Assembler messages:
arch/powerpc/kernel/exceptions-64s.S:865: Error: attempt to move .org backwards
arch/powerpc/kernel/exceptions-64s.S:866: Error: attempt to move .org backwards
arch/powerpc/kernel/exceptions-64s.S:890: Error: attempt to move .org backwards

when compiling ppc:allmodconfig.

This time the problem has been caused by to commit 0869b6fd209bda
("powerpc/book3s: Add basic infrastructure to handle HMI in Linux"),
which adds functions hmi_exception_early and hmi_exception_after_realmode
into a critical (size-limited) code area, even though that does not appear
to be necessary.

Move those functions to a non-critical area of the file.

Subject: powerpc: Add smp_mb() to arch_spin_is_locked()

The kernel defines the function spin_is_locked(), which can be used to
check if a spinlock is currently locked.

Using spin_is_locked() on a lock you don't hold is obviously racy. That
is, even though you may observe that the lock is unlocked, it may become
locked at any time.

There is (at least) one exception to that, which is if two locks are
used as a pair, and the holder of each checks the status of the other
before doing any update.

Assuming *A and *B are two locks, and *COUNTER is a shared non-atomic
value:

The first CPU does:

	spin_lock(*A)

	if spin_is_locked(*B)
		# nothing
	else
		smp_mb()
		LOAD r = *COUNTER
		r++
		STORE *COUNTER = r

	spin_unlock(*A)

And the second CPU does:

	spin_lock(*B)

	if spin_is_locked(*A)
		# nothing
	else
		smp_mb()
		LOAD r = *COUNTER
		r++
		STORE *COUNTER = r

	spin_unlock(*B)

Although this is a strange locking construct, it should work.

It seems to be understood, but not documented, that spin_is_locked() is
not a memory barrier, so in the examples above and below the caller
inserts its own memory barrier before acting on the result of
spin_is_locked().

For now we assume spin_is_locked() is implemented as below, and we break
it out in our examples:

	bool spin_is_locked(*LOCK) {
		LOAD l = *LOCK
		return l.locked
	}

Our intuition is that there should be no problem even if the two code
sequences run simultaneously such as:

	CPU 0			CPU 1
	==================================================
	spin_lock(*A)		spin_lock(*B)
	LOAD b = *B		LOAD a = *A
	if b.locked # true	if a.locked # true
	# nothing		# nothing
	spin_unlock(*A)		spin_unlock(*B)

If one CPU gets the lock before the other then it will do the update and
the other CPU will back off:

	CPU 0			CPU 1
	==================================================
	spin_lock(*A)
	LOAD b = *B
				spin_lock(*B)
	if b.locked # false	LOAD a = *A
	else			if a.locked # true
	smp_mb()		# nothing
	LOAD r1 = *COUNTER	spin_unlock(*B)
	r1++
	STORE *COUNTER = r1
	spin_unlock(*A)

However in reality spin_lock() itself is not indivisible. On powerpc we
implement it as a load-and-reserve and store-conditional.

Ignoring the retry logic for the lost reservation case, it boils down to:
	spin_lock(*LOCK) {
		LOAD l = *LOCK
		l.locked = true
		STORE *LOCK = l
		ACQUIRE_BARRIER
	}

The ACQUIRE_BARRIER is required to give spin_lock() ACQUIRE semantics as
defined in memory-barriers.txt:

     This acts as a one-way permeable barrier.  It guarantees that all
     memory operations after the ACQUIRE operation will appear to happen
     after the ACQUIRE operation with respect to the other components of
     the system.

On modern powerpc systems we use lwsync for ACQUIRE_BARRIER. lwsync is
also know as "lightweight sync", or "sync 1".

As described in Power ISA v2.07 section B.2.1.1, in this scenario the
lwsync is not the barrier itself. It instead causes the LOAD of *LOCK to
act as the barrier, preventing any loads or stores in the locked region
from occurring prior to the load of *LOCK.

Whether this behaviour is in accordance with the definition of ACQUIRE
semantics in memory-barriers.txt is open to discussion, we may switch to
a different barrier in future.

What this means in practice is that the following can occur:

	CPU 0			CPU 1
	==================================================
	LOAD a = *A 		LOAD b = *B
	a.locked = true		b.locked = true
	LOAD b = *B		LOAD a = *A
	STORE *A = a		STORE *B = b
	if b.locked # false	if a.locked # false
	else			else
	smp_mb()		smp_mb()
	LOAD r1 = *COUNTER	LOAD r2 = *COUNTER
	r1++			r2++
	STORE *COUNTER = r1
				STORE *COUNTER = r2	# Lost update
	spin_unlock(*A)		spin_unlock(*B)

That is, the load of *B can occur prior to the store that makes *A
visibly locked. And similarly for CPU 1. The result is both CPUs hold
their lock and believe the other lock is unlocked.

The easiest fix for this is to add a full memory barrier to the start of
spin_is_locked(), so adding to our previous definition would give us:

	bool spin_is_locked(*LOCK) {
		smp_mb()
		LOAD l = *LOCK
		return l.locked
	}

The new barrier orders the store to the lock we are locking vs the load
of the other lock:

	CPU 0			CPU 1
	==================================================
	LOAD a = *A 		LOAD b = *B
	a.locked = true		b.locked = true
	STORE *A = a		STORE *B = b
	smp_mb()		smp_mb()
	LOAD b = *B		LOAD a = *A
	if b.locked # true	if a.locked # true
	# nothing		# nothing
	spin_unlock(*A)		spin_unlock(*B)

Although the above example is theoretical, there is code similar to this
example in sem_lock() in ipc/sem.c. This commit in addition to the next
commit appears to be a fix for crashes we are seeing in that code where
we believe this race happens in practice.

Subject: powerpc: Add smp_mb()s to arch_spin_unlock_wait()

Similar to the previous commit which described why we need to add a
barrier to arch_spin_is_locked(), we have a similar problem with
spin_unlock_wait().

We need a barrier on entry to ensure any spinlock we have previously
taken is visibly locked prior to the load of lock->slock.

It's also not clear if spin_unlock_wait() is intended to have ACQUIRE
semantics. For now be conservative and add a barrier on exit to give it
ACQUIRE semantics.

Subject: powerpc/powernv: Fix IOMMU group lost

When we take full hotplug to recover from EEH errors, PCI buses
could be involved. For the case, the child devices of involved
PCI buses can't be attached to IOMMU group properly, which is
caused by commit 3f28c5a ("powerpc/powernv: Reduce multi-hit of
iommu_add_device()").

When adding the PCI devices of the newly created PCI buses to
the system, the IOMMU group is expected to be added in (C).
(A) fails to bind the IOMMU group because bus->is_added is
false. (B) fails because the device doesn't have binding IOMMU
table yet. bus->is_added is set to true at end of (C) and
pdev->is_added is set to true at (D).

         pci_bus_add_devices()
            pci_bus_add_device()                    D: Add device

If the parent PCI bus isn't involved in hotplug, the IOMMU
group is expected to be bound in (B). (A) should fail as the
sysfs entries aren't populated.

The patch fixes the issue by reverting commit 3f28c5a and remove
WARN_ON() in iommu_add_device() to allow calling the function
even the specified device already has associated IOMMU group.

Subject: powerpc/ppc476: Disable BTAC

This patch disables the branch target address CAM which under specific
circumstances may cause the processor to skip execution of 1-4
instructions. This fixes IBM Erratum #47.

Subject: powerpc: Add POWER8 features to CPU_FTRS_POSSIBLE/ALWAYS

We have been a bit slack about updating the CPU_FTRS_POSSIBLE and
CPU_FTRS_ALWAYS masks. When we added POWER8, and also POWER8E we forgot
to update the ALWAYS mask. And when we added POWER8_DD1 we forgot to
update both the POSSIBLE and ALWAYS masks.

Luckily this hasn't caused any actual bugs AFAICS. Failing to update the
ALWAYS mask just forgoes a potential optimisation opportunity. Failing
to update the POSSIBLE mask for POWER8_DD1 is also OK because it only
removes a bit rather than adding any.

Regardless they should all be in both masks so as to avoid any future
bugs when the set of ALWAYS/POSSIBLE bits changes, or the masks
themselves change.

Subject: powerpc/powernv: Interface to register/unregister opal dump region

PowerNV platform is capable of capturing host memory region when system
crashes (because of host/firmware). We have new OPAL API to register/
unregister memory region to be captured when system crashes.

This patch adds support for new API. Also during boot time we register
kernel log buffer and unregister before doing kexec.

Subject: powerpc/pseries: Avoid deadlock on removing ddw

Function remove_ddw() could be called in of_reconfig_notifier and
we potentially remove the dynamic DMA window property, which invokes
of_reconfig_notifier again. Eventually, it leads to the deadlock as
following backtrace shows.

The patch fixes the above issue by deferring releasing the dynamic
DMA window property while releasing the device node.

Subject: powerpc: remove duplicate definition of TEXASR_FS

It appears that commits 7f06f21d40a6 ("powerpc/tm: Add checking to
treclaim/trechkpt") and e4e38121507a ("KVM: PPC: Book3S HV: Add
transactional memory support") both added definitions of TEXASR_FS.
Remove one of them. At the same time, fix the alignment of the remaining
definition (should be tab-separated like the rest of the #defines).

Subject: powerpc: Hard disable interrupts in xmon

xmon only soft disables interrupts. This seems like a bad idea - we
certainly don't want decrementer and PMU exceptions going off when
we are debugging something inside xmon.

This issue was uncovered when the hard lockup detector went off
inside xmon. To ensure we wont get a spurious hard lockup warning,
I also call touch_nmi_watchdog() when exiting xmon.

Subject: powerpc: reorder per-cpu NUMA information's initialization

There is an issue currently where NUMA information is used on powerpc
(and possibly ia64) before it has been read from the device-tree, which
leads to large slab consumption with CONFIG_SLUB and memoryless nodes.

NUMA powerpc non-boot CPU's cpu_to_node/cpu_to_mem is only accurate
after start_secondary(), similar to ia64, which is invoked via
smp_init().

Commit 6ee0578b4daae ("workqueue: mark init_workqueues() as
early_initcall()") made init_workqueues() be invoked via
do_pre_smp_initcalls(), which is obviously before the secondary
processors are online.

Additionally, the following commits changed init_workqueues() to use
cpu_to_node to determine the node to use for kthread_create_on_node:

bce903809ab3f ("workqueue: add wq_numa_tbl_len and
wq_numa_possible_cpumask[]")
f3f90ad469342 ("workqueue: determine NUMA node of workers accourding to
the allowed cpumask")

Therefore, when init_workqueues() runs, it sees all CPUs as being on
Node 0. On LPARs or KVM guests where Node 0 is memoryless, this leads to
a high number of slab deactivations
(http://www.spinics.net/lists/linux-mm/msg67489.html).

Fix this by initializing the powerpc-specific CPU<->node/local memory
node mapping as early as possible, which on powerpc is
do_init_bootmem(). Currently that function initializes the mapping for
the boot CPU, but we extend it to setup the mapping for all possible
CPUs. Then, in smp_prepare_cpus(), we can correspondingly set the
per-cpu values for all possible CPUs. That ensures that before the
early_initcalls run (and really as early as possible), the per-cpu NUMA
mapping is accurate.

While testing memoryless nodes on PowerKVM guests with a fix to the
workqueue logic to use cpu_to_mem() instead of cpu_to_node(), with a
guest topology of:

available: 2 nodes (0-1)
node 0 cpus: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49
node 0 size: 0 MB
node 0 free: 0 MB
node 1 cpus: 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99
node 1 size: 16336 MB
node 1 free: 15329 MB
node distances:
node   0   1
  0:  10  40
  1:  40  10

the slab consumption decreases from

Slab:             932416 kB
SUnreclaim:       902336 kB

to

Slab:             395264 kB
SUnreclaim:       359424 kB

And we a corresponding increase in the slab efficiency from

slab                                   mem     objs    slabs
                                      used   active   active

task_struct                          31 MB  100.00%  100.00%

Powerpc didn't support memoryless nodes until recently (64bb80d87f01
"powerpc/numa: Enable CONFIG_HAVE_MEMORYLESS_NODES" and 8c272261194d
"powerpc/numa: Enable USE_PERCPU_NUMA_NODE_ID"). Those commits also
helped improve memory consumption with these kind of environments.

Subject: powerpc/thp: Invalidate old 64K based hash page mapping before insert
 of 4k pte

If we changed base page size of the segment, either via sub_page_protect
or via remap_4k_pfn, we do a demote_segment which doesn't flush the hash
table entries. We do a lazy hash page table flush for all mapped pages
in the demoted segment. This happens when we handle hash page fault
for these pages.

We use _PAGE_COMBO bit along with _PAGE_HASHPTE to indicate whether a
pte is backed by 4K hash pte. If we find _PAGE_COMBO not set on the pte,
that implies that we could possibly have older 64K hash pte entries in
the hash page table and we need to invalidate those entries.

Handle this correctly for 16M pages

Subject: powerpc/thp: Handle combo pages in invalidate

If we changed base page size of the segment, either via sub_page_protect
or via remap_4k_pfn, we do a demote_segment which doesn't flush the hash
table entries. We do a lazy hash page table flush for all mapped pages
in the demoted segment. This happens when we handle hash page fault for
these pages.

We use _PAGE_COMBO bit along with _PAGE_HASHPTE to indicate whether a
pte is backed by 4K hash pte. If we find _PAGE_COMBO not set on the pte,
that implies that we could possibly have older 64K hash pte entries in
the hash page table and we need to invalidate those entries.

Use _PAGE_COMBO to determine the page size with which we should
invalidate the hash table entries on unmap.

Subject: powerpc/thp: Invalidate with vpn in loop

As per ISA, for 4k base page size we compare 14..65 bits of VA specified
with the entry_VA in tlb. That implies we need to make sure we do a
tlbie with all the possible 4k va we used to access the 16MB hugepage.
With 64k base page size we compare 14..57 bits of VA. Hence we cannot
ignore the lower 24 bits of va while tlbie .We also cannot tlb
invalidate a 16MB entry with just one tlbie instruction because
we don't track which va was used to instantiate the tlb entry.

Subject: powerpc/mm: Use read barrier when creating real_pte

On ppc64 we support 4K hash pte with 64K page size. That requires
us to track the hash pte slot information on a per 4k basis. We do that
by storing the slot details in the second half of pte page. The pte bit
_PAGE_COMBO is used to indicate whether the second half need to be
looked while building real_pte. We need to use read memory barrier while
doing that so that load of hidx is not reordered w.r.t _PAGE_COMBO
check. On the store side we already do a lwsync in __hash_page_4K

Subject: sparc64: Expand PCI bridge probing debug logging.

Dump the various aspects of the PCI bridge probed at boot time, most
importantly the bridge number ranges, and the ranges property.

This helps diagnose PCI resource issues and other problems by giving
ofpci_debug=1 on the boot command line.

Subject: sparc64: Skip bogus PCI bridge ranges.

It seems that when a PCI Express bridge is not in use and has no devices
behind it, the ranges property is bogus.  Specifically the size property
is of the form [0xffffffff:...], and if you add this size to the resource
start address the 64-bit calculation will overflow.

Just check specifically for this size value signature and skip them.

"efi" global data structure contains "runtime_version" field which must
be assigned in order to use it later in Runtime Services virtual calls
(virt_efi_* functions).

Before this patch "runtime_version" was unassigned (0), so each
Runtime Service virtual call that checks revision would fail.
