driverDate:Wed, 17 Oct 2012 13:55:55 -0500
Add dmtimer clock aliases for AM33XX devices so that the parent clock for
the dmtimer can be set correctly by the dmtimer driver. Without these clock
aliases the dmtimer driver will fail to find the parent clocks for the dmtimer.
Verified that DMTIMERs can be successfully requested on AM335x beagle bone.
Original patch was provided by Vaibhav Hiremath [1]. Changelog and
additional verification performed by Jon Hunter.

After commit 24d7b40a60cf19008334bcbcbd98da374d4d9c64 (ARM: OMAP2+:
PM: MPU DVFS: use generic CPU device for MPU-SS), OPPs are registered
using an existing CPU device, not the omap_device for MPU-SS.
First, fix the board file to use get_cpu_device() as required by the
above commit, otherwise custom OPPs will be added to the wrong device.
Second, the board files OPP init is called from the its init_machine
method, and the generic CPU devices are not yet created when
init_machine is run. Therefore OPP initialization will fail. To fix,
use a device_initcall() for the board file's OPP customization, and
make the device_initcall board-specific by using a machine_is check.

The runtime PM framework assumes that the hardware state of devices
when initialized is disabled. For all omap_devices, we idle/disable
device by default. However, the console uart uses a "no idle" option
during omap_device init in order to allow earlyprintk usage to work
seamlessly during boot.
Because the hardware is left partially enabled after init (whatever
the bootloader settings were), the omap_device should later be fully
initialized (including mux) and the runtime PM framework should be
told that the device is active, and not disabled so that the hardware
state is in sync with runtime PM state.
To fix, after the device has been created/registered, call
omap_device_enable() to finialize init and use pm_runtime_set_active()
to tell the runtime PM core the device is enabled.
Tested on 2420/n810, 3530/Overo, 3530/Beagle, 3730/OveroSTORM,
3730/Beagle-xM, 4460/PandaES.

On OMAP34xx/35xx, and OMAP36xx chips with ES < 1.2, if the PER
powerdomain goes to OSWR or OFF while CORE stays at CSWR or ON, or if,
upon chip wakeup from OSWR or OFF, the CORE powerdomain goes ON before
PER, the UART3/4 FIFOs and McBSP2/3 SIDETONE memories will be
unusable. This is erratum i582 in the OMAP36xx Silicon Errata
document.
This patch implements one of several parts of the workaround: the
addition of the wakeup dependency between the PER and WKUP
clockdomains, such that PER will wake up at the same time CORE_L3
does.
This is not a complete workaround. For it to be complete:
1. the PER powerdomain's next power state must not be set to OSWR or
OFF if the CORE powerdomain's next power state is set to CSWR or
ON;
2. the UART3/4 FIFO and McBSP2/3 SIDETONE loopback tests should be run
if the LASTPOWERSTATEENTERED bits for PER and CORE indicate that
PER went OFF while CORE stayed on. If loopback tests fail, then
those devices will be unusable until PER and CORE can undergo a
transition from ON to OSWR/OFF and back ON.

On n900 uart1 pins are not not used for uart, instead they are
used to connect to a cell modem over ssi. Looks like we're
currently missing these signal names for 3430 for some reason,
and only have some of them listed for 3630. Obviously the signals
are there for 3430 if n900 is using them and they are documented
in some TRMs.
Note that these will eventually be replaced by device tree
based pinctrl-single.c driver. But for now these are needed
to verify the SSI pins for devices like Nokia N900.

Commit 8f31cefe (ARM: OMAP2+: select PINCTRL in Kconfig)
added select PINCTRL, but accdentally added it to a wrong
location.
We want to select if for ARCH_OMAP2PLUS, not for
ARCH_OMAP2PLUS_TYPICAL.

Fixes the following errors:
[ 2.318084] omap-mcbsp 49022000.mcbsp: invalid rx DMA channel
[ 2.324432] omap-mcbsp 49024000.mcbsp: invalid rx DMA channel
Which is because we failed to link the sidetone hwmod for McBSP2/3. The
missing sidetone hwmod link will prevent omap_device_alloc() to append the
DMA resources since we - accidentally - end up having the same number of
resources provided from DT (IO/IRQ) as we have in hwmod for the McBSP ports
without the ST resources.

An interesting effect of using the generic version of linkage.h
is that the padding is defined in terms of x86 NOPs, which can have
even more interesting effects when the assembly code looks like this:
ENTRY(func1)
mov x0, xzr
ENDPROC(func1)
// fall through
ENTRY(func2)
mov x0, #1
ret
ENDPROC(func2)
Admittedly, the code is not very nice. But having code from another
architecture doesn't look completely sane either.
The fix is to add arm64's version of linkage.h, which causes the insertion
of proper AArch64 NOPs.

If a debugger tries to zero a hardware debug control register, the
kernel will try to infer both the type and length of the breakpoint
in order to sanity-check against the requested regset type. This will
fail because the encoding will appear as a zero-length breakpoint.
This patch changes the control register setting so that disabled
breakpoints are treated as HW_BREAKPOINT_EMPTY and no further
sanity-checking is required.

The user_hwdebug_state structure contains implicit padding to conform to
the alignment requirements of the AArch64 ABI (namely that aggregates
must be aligned to their most aligned member).
This patch fixes the ptrace functions operating on struct
user_hwdebug_state so that the padding is handled correctly.

For historical reasons, ARM used to set r0-r2 in start_thread() to the
first values on the user stack when starting a new user application. The
same logic has been inherited in AArch64. The x0 register is overridden
by the sys_execve() return value so it's always zero on success. The x1
and x2 registers are ignored by AArch64 and EABI AArch32 applications,
so we can safely remove the register setting for both native and compat
user space.
This also fixes a potential fault with the kernel accessing user space
stack directly.

According to Documentation/arm64/booting.txt, the kernel image must be
loaded at a pre-defined offset from the start of RAM so that the kernel
can calculate PHYS_OFFSET based on this address. If the DT contains
memory blocks below this PHYS_OFFSET, report them and ignore the
corresponding memory range.

The min/max call needed to have explicit types on some architectures
(e.g. mn10300). Use clamp_t instead to avoid the warning:

git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
Pull perf/urgent fixes from Arnaldo Carvalho de Melo:
* The python binding needs to link with libtraceevent and to initialize
the 'page_size' variable so that mmaping works again.
* The callchain folding character that appears on the TUI just before
the overhead had disappeared due to recent changes, add it back.
* Intel PEBS in VT-x context uses the DS address as a guest linear address,
even though its programmed by the host as a host linear address. This either
results in guest memory corruption and or the hardware faulting and 'crashing'
the virtual machine. Therefore we have to disable PEBS on VT-x enter and
re-enable on VT-x exit, enforcing a strict exclude_guest.
Kernel side enforcement fix by Peter Zijlstra, tooling side fix by David Ahern.
* Fix build on sparc due to UAPI, fix from David Miller.
* Fixes for the srclike sort key for unresolved symbols and when processing
samples in JITted code, where we don't have an ELF file, just an special
symbol table, fixes from Namhyung Kim.
* Fix some leaks in libtraceevent, from Steven Rostedt.

The commit 5395a04841fc ("perf hists: Separate overhead and baseline
columns") makes the "Overhead" column no more the first one, this
caused the test that checks if it is time to show if a histogram
entry has callchains never hits.
Fix it by checking if the 'i' variable is equal to PERF_HPP__OVERHEAD
instead of 0.

The commit 0c1fe6b:
'perf tools: Have the page size value available for all tools'
Broke the python binding because the global variable 'page_size' is
initialized on the main() routine, that is not called when using
just the python binding, causing evlist.mmap() to fail because it
expects that variable to be initialized to the system's page size.
Fix it by initializing it on the binding init routine.
