d3e5116119 pinctrl: add pinctrl driver for Rockchip SoCs
This driver adds support the Cortex-A9 based SoCs from Rockchip,
so at least the RK2928, RK3066 (a and b) and RK3188.
Earlier Rockchip SoCs seem to use similar mechanics for gpio
handling so should be supportable with relative small changes.
Pull handling on the rk3188 is currently a stub, due to it being
a bit different to the earlier SoCs.

Pinmuxing as well as gpio (and interrupt-) handling tested on
a rk3066a based machine.

7db9af4b6e pinctrl: add function to parse generic pinconfig properties from a dt node
pinconf_generic_parse_dt_config() takes a node as input and generates an
array of generic pinconfig values from the properties of this node.

As I couldn't find a mechanism to count the number of properties of a node
the function uses internally an array to accept one of parameter and copies
the real present options to a smaller variable at its end.

Add support to configure multiple pins in each register, existing
implementation added by [1] does not support full fledge multiple pin
configuration in single register, reports a pin clash when different
modules configure different bits of same register. The issue reported
and discussed here
http://www.spinics.net/lists/arm-kernel/msg235213.html

With pinctrl-single,bits-per-mux property specified, use function-mask
property to find out number pins to configure. Allocate and register
pin control functions based sub mask.

Tested on da850/omap-l138 EVM.
does not support variable submask for pins.
does not support pinconf.

 "Here are several fixes for filesystems with CRC support turned on:
  fixes for quota, remote attributes, and recovery.  There is also some
  feature work related to CRCs: the implementation of CRCs for the inode
  unlinked lists, disabling noattr2/attr2 options when appropriate, and
  bumping the maximum number of ACLs.

  I would have preferred to defer this last category of items to 3.11.
  This would require setting a feature bit for the on-disk changes, so
  there is some pressure to get these in 3.10.  I believe this
  represents the end of the CRC related queue.

2b3f8e87cf powerpc/tm: Fix userspace stack corruption on signal delivery for active transactions
When in an active transaction that takes a signal, we need to be careful with
the stack.  It's possible that the stack has moved back up after the tbegin.
The obvious case here is when the tbegin is called inside a function that
returns before a tend.  In this case, the stack is part of the checkpointed
transactional memory state.  If we write over this non transactionally or in
suspend, we are in trouble because if we get a tm abort, the program counter
and stack pointer will be back at the tbegin but our in memory stack won't be
valid anymore.

To avoid this, when taking a signal in an active transaction, we need to use
the stack pointer from the checkpointed state, rather than the speculated
state.  This ensures that the signal context (written tm suspended) will be
written below the stack required for the rollback.  The transaction is aborted
becuase of the treclaim, so any memory written between the tbegin and the
signal will be rolled back anyway.

For signals taken in non-TM or suspended mode, we use the
normal/non-checkpointed stack pointer.

Tested with 64 and 32 bit signals

6ce6c629fd powerpc/tm: Abort on emulation and alignment faults
If we are emulating an instruction inside an active user transaction that
touches memory, the kernel can't emulate it as it operates in transactional
suspend context.  We need to abort these transactions and send them back to
userspace for the hardware to rollback.

We can service these if the user transaction is in suspend mode, since the
kernel will operate in the same suspend context.

This adds a check to all alignment faults and to specific instruction
emulations (only string instructions for now).  If the user process is in an
active (non-suspended) transaction, we abort the transaction go back to
userspace allowing the HW to roll back the transaction and tell the user of the
failure.  This also adds new tm abort cause codes to report the reason of the
persistent error to the user.

Crappy test case here http://neuling.org/devel/junkcode/aligntm.c

26549c8d36 drivers/video: implement a simple framebuffer driver
A simple frame-buffer describes a raw memory region that may be rendered
to, with the assumption that the display hardware has already been set
up to scan out from that buffer.

This is useful in cases where a bootloader exists and has set up the
display hardware, but a Linux driver doesn't yet exist for the display
hardware.

Examples use-cases include:

* The built-in LCD panels on the Samsung ARM chromebook, and Tegra
  devices, and likely many other ARM or embedded systems.  These cannot
  yet be supported using a full graphics driver, since the panel control
  should be provided by the CDF (Common Display Framework), which has been
  stuck in design/review for quite some time.  One could support these
  panels using custom SoC-specific code, but there is a desire to use
  common infra-structure rather than having each SoC vendor invent their
  own code, hence the desire to wait for CDF.

* Hardware for which a full graphics driver is not yet available, and
  the path to obtain one upstream isn't yet clear.  For example, the
  Raspberry Pi.

* Any hardware in early stages of upstreaming, before a full graphics
  driver has been tackled.  This driver can provide a graphical boot
  console (even full X support) much earlier in the upstreaming process,
  thus making new SoC or board support more generally useful earlier.

37d46e152e xen/tmem: Don't use self[ballooning|shrinking] if frontswap is off.
There is no point. We would just squeeze the guest to put more and
more pages in the swap disk without any purpose.

The only time it makes sense to use the selfballooning and shrinking
is when frontswap is being utilized.

daf799cca8 Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS updates from Ralf Baechle:

 - More work on DT support for various platforms

 - Various fixes that were to late to make it straight into 3.9

 - Improved platform support, in particular the Netlogic XLR and
   BCM63xx, and the SEAD3 and Malta eval boards.

 - Support for several Ralink SOC families.

 - Complete support for the microMIPS ASE which basically reencodes the
   existing MIPS32/MIPS64 ISA to use non-constant size instructions.

 - Some fallout from LTO work which remove old cruft and will generally
   make the MIPS kernel easier to maintain and resistant to compiler
   optimization, even in absence of LTO.

 - KVM support.  While MIPS has announced hardware virtualization
   extensions this KVM extension uses trap and emulate mode for
   virtualization of MIPS32.  More KVM work to add support for VZ
   hardware virtualizaiton extensions and MIPS64 will probably already
   be merged for 3.11.

Most of this has been sitting in -next for a long time.  All defconfigs
have been build or run time tested except three for which fixes are being
sent by other maintainers.

 Largest continous series is for OMAP, but there's a handful for other

Pull btrfs update from Chris Mason:
 "These are mostly fixes.  The biggest exceptions are Josef's skinny
  extents and Jan Schmidt's code to rebuild our quota indexes if they
  get out of sync (or you enable quotas on an existing filesystem).

  The skinny extents are off by default because they are a new variation
  on the extent allocation tree format.  btrfstune -x enables them, and
  the new format makes the extent allocation tree about 30% smaller.

  I rebased this a few days ago to rework Dave Sterba's crc checks on
  the super block, but almost all of these go back to rc6, since I
  though 3.9 was due any minute.

  The biggest missing fix is the tracepoint bug that was hit late in
  3.9.  I ran into problems with that in overnight testing and I'm still
  tracking it down.  I'll definitely have that fixed for rc2."

5647ac0ad4 Removal of GENERIC_GPIO for v3.10
GENERIC_GPIO now synonymous with GPIOLIB. There are no longer any valid
 cases for enableing GENERIC_GPIO without GPIOLIB, even though it is
 possible to do so which has been causing confusion and breakage. This
 branch does the work to completely eliminate GENERIC_GPIO.
 
 However, it is not trivial to just create a branch to remove it. Over
 the course of the v3.9 cycle more code referencing GENERIC_GPIO has been
 added to linux-next that conflicts with this branch. The following must
 be done to resolve the conflicts when merging this branch into mainline:
 
 * "git grep CONFIG_GENERIC_GPIO" should return 0 hits. Matches should be
   replaced with CONFIG_GPIOLIB
 * "git grep '\bGENERIC_GPIO\b'" should return 1 hit in the Chinese
   documentation.
 * Selectors of GENERIC_GPIO should be turned into selectors of GPIOLIB
 * definitions of the option in architecture Kconfig code should be deleted.
 
 Stephen has 3 merge fixup patches[1] that do the above. They are currently
 applicable on mainline as of May 2nd.

Pull thermal management update from Zhang Rui:
 "The most important one is to build thermal core and governor and cpu
  cooling code into one module.  This fixes a regression that thermal
  core does not work if it is built as module, since 3.7.  I'll backport
  them to stable kernel once those changes are in upstream.

  The largest batch is the thermal kernel-doc & coding style
  updates/cleanups from Eduardo.

  Highlights:

   - build all thermal framework code into one module to fix a
     regression that thermal does not work if it is built as module.

   - Marvell Armada 370/XP thermal sensor driver

   - thermal core/cpu cooling kernel-doc & coding style updates and
     cleanups.

   - Add Eduardo Valentin as thermal sub-maintainer, both in mailing
     list and patchwork.  He will help me on arm thermal drivers."

 - Various fixes which were stalled or which I picked up recently

 - A large rotorooting of the AIO code.  Allegedly to improve
   performance but I don't really have good performance numbers (I might
   have lost the email) and I can't raise Kent today.  I held this out
   of 3.9 and we could give it another cycle if it's all too late/scary.

I ended up taking only the first two thirds of the AIO rotorooting.  I
left the percpu parts and the batch completion for later.  - Linus

b070e65c0b mm, memcg: add rss_huge stat to memory.stat
This exports the amount of anonymous transparent hugepages for each
memcg via the new "rss_huge" stat in memory.stat.  The units are in
bytes.

This is helpful to determine the hugepage utilization for individual
jobs on the system in comparison to rss and opportunities where
MADV_HUGEPAGE may be helpful.

The amount of anonymous transparent hugepages is also included in "rss"
for backwards compatibility.

bb9055b274 ARM: late Exynos multiplatform changes
These continue the multiplatform support for exynos, adding support
 for building most of the essential drivers (clocksource, clk, irqchip)
 when combined with other platforms. As a result, it should become
 really easy to add full multiplatform exynos support in 3.11, although
 we don't yet enable it for 3.10.
 
 The changes were not included in the earlier multiplatform series
 in order to avoid clashes with the other Exynos updates.
 
 This also includes work from Tomasz Figa to fix the pwm clocksource
 code on Exynos, which is not strictly required for multiplatform,
 but related to the other patches in this set and needed as a bug
 fix for at least one board.

1bf25e78af ARM: arm-soc: late cleanups
These are cleanups and smaller changes that either depend on earlier

 We normally try to get all cleanups early, so these are the exceptions:
 
 - A follow-up on the clocksource reworks, hopefully the last time
   we need to merge clocksource subsystem changes through arm-soc.
   A first set of patches was part of the original 3.10 arm-soc cleanup
   series because of interdependencies with timer drivers now moved out
   of arch/arm.
 
 - Migrating the SPEAr13xx platform away from using auxdata for DMA
   channel descriptions towards using information in device tree,
   based on the earlier SPEAr multiplatform series
 
 - A few follow-ups on the Atmel SAMA5 support and other changes
   for Atmel at91 based on the larger at91 reworks.

38f56f33ca ARM: arm-soc device tree changes, part 2
These are mostly new device tree bindings for existing drivers, as well
 as changes to the device tree source files to add support for those
 devices, and a couple of new boards, most notably Samsung's Exynos5
 based Chromebook.
 
 The changes depend on earlier platform specific updates and touch
 the usual platforms: omap, exynos, tegra, mxs, mvebu and davinci.

fcba914542 ARM: arm-soc platform updates for 3.10, part 3
This is the third and smallest of the SoC specific updates.
 Changes include:
 
 * SMP support for the Xilinx zynq platform
 * Smaller imx changes
 * LPAE support for mvebu
 * Moving the orion5x, kirkwood, dove and mvebu platforms
   to a common "mbus" driver for their internal devices.
 
 It would be good to get feedback on the location of the "mbus"
 driver. Since this is used on multiple platforms may potentially
 get shared with other architectures (powerpc and arm64), it
 was moved to drivers/bus/. We expect other similar drivers to
 get moved to the same place in order to avoid creating more
 top-level directories under drivers/ or cluttering up the
 messy drivers/misc/ even more.

Pull misc kbuild updates from Michal Marek:
 "Non-critical kbuild changes:

   - make coccicheck improvements, but no new semantic patches this time

   - make rpm improvements

   - make tar-pkg change to include the architecture in the filename.

     This is a deliberate incompatibility, but nobody has complained so
     far and it is useful if you build for different architectures.  It
     also matches what the deb-pkg and rpm-pkg targets produce.

   - kbuild documentation fix"
