Race conditions are theoretically possible between the PCI device addition
and removal in the PPC64 PCI error recovery driver and the generic PCI bus
rescan and device removal that can be triggered via sysfs.
To avoid those race conditions make PPC64 PCI error recovery driver use
global PCI rescan-remove locking around PCI device addition and removal.

When allocating space for 32-bit BARs, we previously limited RESOURCE
addresses so they would fit in 32 bits. However, the BUS address need not
be the same as the resource address, and it's the bus address that must fit
in the 32-bit BAR.
This patch adds:
- pci_clip_resource_to_region(), which clips a resource so it contains
only the range that maps to the specified bus address region, e.g., to
clip a resource to 32-bit bus addresses, and
- pci_bus_alloc_from_region(), which allocates space for a resource from
the specified bus address region,
and changes pci_bus_alloc_resource() to allocate space for 64-bit BARs from
the entire bus address region, and space for 32-bit BARs from only the bus
address region below 4GB.
If we had this window:
pci_root HWP0002:0a: host bridge window [mem 0xf0180000000-0xf01fedfffff] (bus address [0x80000000-0xfedfffff])
we previously could not put a 32-bit BAR there, because the CPU addresses
don't fit in 32 bits. This patch fixes this, so we can use this space for
32-bit BARs.
It's also possible (though unlikely) to have resources with 32-bit CPU
addresses but bus addresses above 4GB. In this case the previous code
would allocate space that a 32-bit BAR could not map.
Remove PCIBIOS_MAX_MEM_32, which is no longer used.

These interfaces:
pcibios_resource_to_bus(struct pci_dev *dev, *bus_region, *resource)
pcibios_bus_to_resource(struct pci_dev *dev, *resource, *bus_region)
took a pci_dev, but they really depend only on the pci_bus. And we want to
use them in resource allocation paths where we have the bus but not a
device, so this patch converts them to take the pci_bus instead of the
pci_dev:
pcibios_resource_to_bus(struct pci_bus *bus, *bus_region, *resource)
pcibios_bus_to_resource(struct pci_bus *bus, *resource, *bus_region)
In fact, with standard PCI-PCI bridges, they only depend on the host
bridge, because that's the only place address translation occurs, but
we aren't going that far yet.

Change x86_msi.restore_msi_irqs(struct pci_dev *dev, int irq) to
x86_msi.restore_msi_irqs(struct pci_dev *dev).
restore_msi_irqs() restores multiple MSI-X IRQs, so param 'int irq' is
unneeded. This makes code more consistent between vm and bare metal.
Dom0 MSI-X restore code can also be optimized as XEN only has a hypercall
to restore all MSI-X vectors at one time.

Switch to memblock interfaces for early memory allocator instead of
bootmem allocator. No functional change in beahvior than what it is in
current code from bootmem users points of view.
Archs already converted to NO_BOOTMEM now directly use memblock
interfaces instead of bootmem wrappers build on top of memblock. And
the archs which still uses bootmem, these new apis just fallback to
exiting bootmem APIs.

Introduce memblock memory allocation APIs which allow to support PAE or
LPAE extension on 32 bits archs where the physical memory start address
can be beyond 4GB. In such cases, existing bootmem APIs which operate
on 32 bit addresses won't work and needs memblock layer which operates
on 64 bit addresses.
So we add equivalent APIs so that we can replace usage of bootmem with
memblock interfaces. Architectures already converted to NO_BOOTMEM use
these new memblock interfaces. The architectures which are still not
converted to NO_BOOTMEM continue to function as is because we still
maintain the fal lback option of bootmem back-end supporting these new
interfaces. So no functional change as such.
In long run, once all the architectures moves to NO_BOOTMEM, we can get
rid of bootmem layer completely. This is one step to remove the core
code dependency with bootmem and also gives path for architectures to
move away from bootmem.
The proposed interface will became active if both CONFIG_HAVE_MEMBLOCK
and CONFIG_NO_BOOTMEM are specified by arch. In case
!CONFIG_NO_BOOTMEM, the memblock() wrappers will fallback to the
existing bootmem apis so that arch's not converted to NO_BOOTMEM
continue to work as is.
The meaning of MEMBLOCK_ALLOC_ACCESSIBLE and MEMBLOCK_ALLOC_ANYWHERE
is kept same.

The memblock current limit value is used to limit early boot memory
allocations below max low memory address by default, as the kernel can
access only to the low memory.
Hence, set memblock current limit value to the max mapped low memory
address instead of max mapped memory address.

At very early time, the kernel have to use some memory such as loading
the kernel image. We cannot prevent this anyway. So any node the
kernel resides in should be un-hotpluggable.

invoke function memblock_mark_hotplug() introduced by previous patch to
mark hotpluggable memory in memblock.

Commit 4b59e6c47309 ("mm, show_mem: suppress page counts in
non-blockable contexts") introduced SHOW_MEM_FILTER_PAGE_COUNT to
suppress PFN walks on large memory machines. Commit c78e93630d15 ("mm:
do not walk all of system memory during show_mem") avoided a PFN walk in
the generic show_mem helper which removes the requirement for
SHOW_MEM_FILTER_PAGE_COUNT in that case.
This patch removes PFN walkers from the arch-specific implementations
that report on a per-node or per-zone granularity. ARM and unicore32
still do a PFN walk as they report memory usage on each bank which is a
much finer granularity where the debugging information may still be of
use. As the remaining arches doing PFN walks have relatively small
amounts of memory, this patch simply removes SHOW_MEM_FILTER_PAGE_COUNT.

Depending on the regulator version, the voltage table might be
different. Use version specific regulator tables in order to select
correct voltage table. For the following regulator versions different
voltage tables are now used:
* TPS658623: Use correct voltage table for SM2
* TPS658643: New voltage table for SM2
Both versions are in use on the Colibri T20 module. Make use of the
correct tables by requesting the correct SM2 voltage of 1.8V.
This change is not backward compatible since an old driver is not able
to correctly set that value. The value 1.8V is out of range for the old
driver and will refuse to probe the device. The regulator starts with
default settings and the driver shows appropriate error messages.
On Colibri T20, the old value used to work with TPS658623 since the
driver applied a wrong voltage table too. However, the TPS658643 used
on V1.2 devices uses yet another voltage table and those broke that
pseudo-compatibility. The regulator driver now has the correct voltage

Pull sound updates from Takashi Iwai:
"It was holiday season, so no wonder that there are little changes in
framework level, although diffstat shows quite many changes spreaded
over sound/* directories. Most of changes are cleanups, code
refactoring and fixes.
Some highlights:
- Removal of OSS sleep_on usages by Arnd
- Simplified memalloc helper codes, drop obsoleted features; now it's
built into PCM driver instead of an individual module
- Warn if PCM buffer preallocation fails, which will show page
allocation issues more clearly
- Compress offload API updates for sample rates by Vinod
- PCM glitch workaround on ctxfi emu20k1 by Sarah
- Drop cs46xx DSP blobs, using firmware loader now
- USB-audio quitks for Plantronics Gamecom 780, Creative VF0420, and
Focusrite Saffire 6
HD-audio specifics:
- Standardize Kconfigs of HD-audio codec drivers; now "make
localmodconfig" recognizes configs properly (finally!)
- Parallel PM implementation by Mengdong
- BayleyBay/ValleyView2 board fixups
- Broadwell audio support
- Runtime PM improvement (PantherPoint, etc)
- Quirks: Dell subwooer, Gigabyte mobo jack detection oddity, Dell
AiO click noise fixes, Dell headset mic fixes, etc
- Automatic bind with HDMI codec parser without generic parser
- More AD codec fixes (since 3.12 regression) including the automatic
stereo mix support
- Common Thinkpad ACPI helper for Realtek and Conexant codecs
ASoC specifics:
- Update to the generic DMA code to support deferred probe and
managed resources
- New drivers for BCM2835 (used in Raspberry Pi), Tegra with MAX98090
and Analog Devices AXI I2S and S/PDIF controller IPs
- Device tree support for the simple card, max98090 and cs42l52
- Conversion of the Samsung drivers to native dmaengine, making them
multiplatform compatible and hopefully helping keep them more
modern and up to date.
- More regmap conversions, including a very welcome one for twl6040
from Peter Ujfalusi
- A big overhaul of the DaVinci drivers also from Peter Ujfalusi
- Lots of DMA updates from Lars-Peter
- Improvements to the constraints handling code from Lars-Peter
- A very helpful conversion of the TWL4030 driver to regmap from Peter
- A new driver for the Freescale ESAI controller from Nicolin Chen
- Conversion of some of the drivers to use params_width()
- Extensions to DPCM for use with compressed audio from Liam"

This patch adds all required platform-specific data and initialization
code to support the generic amba-pl08x driver on S3C64xx SoCs.
Also some compatibility definitions are added to make the transition
from legacy API to DMA engine easier. The biggest hack here is passing
const char * pointers through DMA resource, casted to unsigned long,
but this is how Samsung DMA wrappers (used to support both s3c-dma and
DMA engine in drivers) are designed.

Pull GPIO tree bulk changes from Linus Walleij:
"A big set this merge window, as we have much going on in this
subsystem. The changes to other subsystems (notably a slew of ARM
machines as I am doing away with their custom APIs) have all been
ACKed to the extent possible.
Major changes this time:
- Some core improvements and cleanups to the new GPIO descriptor API.
This seems to be working now so we can start the exodus to this
API, moving gradually away from the global GPIO numberspace.
- Incremental improvements to the ACPI GPIO core, and move the few
GPIO ACPI clients we have to the GPIO descriptor API right *now*
before we go any further. We actually managed to contain this
*before* we started to litter the kernel with yet another hackish
global numberspace for the ACPI GPIOs, which is a big win.
- The RFkill GPIO driver and all platforms using it have been
migrated to use the GPIO descriptors rather than fixed number
assignments. Tegra machine has been migrated as part of this.
- New drivers for MOXA ART, Xtensa GPIO32 and SMSC SCH311x. Those
should be really good examples of how I expect a nice GPIO driver
to look these days.
- Do away with custom GPIO implementations on a major part of the ARM
machines: ks8695, lpc32xx, mv78xx0. Make a first step towards the
same in the horribly convoluted Samsung S3C include forest. We
expect to continue to clean this up as we move forward.
- Flag GPIO lines used for IRQ on adnp, bcm-kona, em, intel-mid and
lynxpoint.
This makes the GPIOlib core aware that a certain GPIO line is used
for IRQs and can then enforce some semantics such as disallowing a
GPIO line marked as in use for IRQ to be switched to output mode.
- Drop all use of irq_set_chip_and_handler_name(). The name provided
in these cases were just unhelpful tags like "mux" or "demux".
- Extend the MCP23s08 driver to handle interrupts.
- Minor incremental improvements for rcar, lynxpoint, em 74x164 and
msm drivers.
- Some non-urgent bug fixes here and there, duplicate #includes and
that usual kind of cleanups"
Fix up broken Kconfig file manually to make this all compile.

Previously the custom GPIO header for the S3C24xx would in turn
bring in the custom pin control implementation from
<plat/gpio-cfg.h>. This is not good as it mixes up two
subsystems and makes the dependencies hard to track. Make
the dependency explicit by explicitly including the pin
control header where needed.

When refactoring and breaking out the includes for the
machine-specific GPIO configuration, two files were created
in <linux/platform_data/gpio-samsung-s3c[24|64]xx.h>, but as
that namespace shall be used for defining data exchanged
between machines and drivers, using it for these broad macros
and config settings is wrong.
Move the headers back into the machine-local
<mach/gpio-samsung.h> file and think about the next step.

When enabling device tree on the S3C an additional build
bug appears in the Osiris DVS board file:
CC arch/arm/mach-s3c24xx/mach-osiris-dvs.o
archh/arm/mach-s3c24xx/mach-osiris-dvs.c:
In function ‘osiris_dvs_notify’:
arch/arm/mach-s3c24xx/mach-osiris-dvs.c:77:4:
error: implicit declaration of function ‘S3C2410_GPB’
[-Werror=implicit-function-declaration]
gpio_set_value(OSIRIS_GPIO_DVS, 1);
^
Fix this by explicitly including
<linux/platform_data/gpio-samsung-s3c24xx.h>
