Pull arm fixes for ux500 mismerge mishap from Arnd Bergmann:
 "The device tree conversion for arm/ux500 in 3.5 turns out to be
  incomplete because of a mismerge done by Linus Walleij that I failed

  those patches did not manage to fix during the -next cycle.  While we
  originally to get a much larger set of ux500 device tree enablement
  patches merged, this did not happen in time.

  After some discussion at Linaro Connect conference this week, Lee has
  been able to do damage control and provide a series to put the broken
  platform back into usable shape for both DT and non-DT based booting.

  This series has not been part of linux-next and is based on top of the
  current state of the upstream kernel rather than an -rc, but this is
  the best we could manage given the earlier breakage."

Al Viro efee984c27 new helper: signal_delivered()
Does block_sigmask() + tracehook_signal_handler();  called when
sigframe has been successfully built.  All architectures converted
to it; block_sigmask() itself is gone now (merged into this one).

I'm still not too happy with the signature, but that's a separate
story (IMO we need a structure that would contain signal number +
siginfo + k_sigaction, so that get_signal_to_deliver() would fill one,
signal_delivered(), handle_signal() and probably setup...frame() -
take one).

Anton Vorontsov 3eaa73bde2 arm: use clear_tasks_mm_cpumask()
Checking for process->mm is not enough because process' main thread may
exit or detach its mm via use_mm(), but other threads may still have a
valid mm.

To fix this we would need to use find_lock_task_mm(), which would walk up
all threads and returns an appropriate task (with task lock held).

clear_tasks_mm_cpumask() has this issue fixed, so let's use it.

Lee Jones f65c1982fa ARM: ux500: New DT:ed u8500_init_devices for one-by-one device enablement
During Device Tree enablement it is necessary to remove
<hw_component>_add_<device> calls one at at time, as and when particular
devices are DT enabled. This patch provides a temporary solution. Once
the new *of_init_devices function has been fully unpopulated it will be
removed again.

The GPIO devicetree binding in 3.5 doesn't register the various LPC32xx GPIO
banks via DT subnodes but always all at once, and changes the gpio referencing
to 3 cells (bank, gpio, flags). This patch adjusts the DTS files to this
binding that was just accepted to the gpio subsystem.

Linus Torvalds f465d145d7 arm-soc: sweeping late_initcall cleanup
This is a patch series from Shawn Guo that moves from individual
 late_initcalls() to using a member in the machine structure to invoke
 a platform's late initcalls.
 
 This cleanup is a step in the move towards multiplatform kernels since
 it would reduce the need to check for compatible platforms in each and
 every initcall.

Merge tag 'clock' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull arm-soc clock driver changes from Olof Johansson:
 "The new clock subsystem was merged in linux-3.4 without any users,
  this now moves the first three platforms over to it: imx, mxs and
  spear.

  The series also contains the changes for the clock subsystem itself,
  since Mike preferred to have it together with the platforms that
  require these changes, in order to avoid interdependencies and
  conflicts."

Fix up trivial conflicts in arch/arm/mach-kirkwood/common.c (code
removed in one branch, added OF support in another) and
drivers/dma/imx-sdma.c (independent changes next to each other).

Linus Torvalds d484864dd9 Merge branch 'for-linus' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping
Pull CMA and ARM DMA-mapping updates from Marek Szyprowski:
 "These patches contain two major updates for DMA mapping subsystem
  (mainly for ARM architecture).  First one is Contiguous Memory
  Allocator (CMA) which makes it possible for device drivers to allocate
  big contiguous chunks of memory after the system has booted.

  The main difference from the similar frameworks is the fact that CMA
  allows to transparently reuse the memory region reserved for the big
  chunk allocation as a system memory, so no memory is wasted when no
  big chunk is allocated.  Once the alloc request is issued, the
  framework migrates system pages to create space for the required big
  chunk of physically contiguous memory.

  For more information one can refer to nice LWN articles:

   - 'A reworked contiguous memory allocator':
		http://lwn.net/Articles/447405/

   - 'CMA and ARM':
		http://lwn.net/Articles/450286/

   - 'A deep dive into CMA':
		http://lwn.net/Articles/486301/

   - and the following thread with the patches and links to all previous
     versions:
		https://lkml.org/lkml/2012/4/3/204

  The main client for this new framework is ARM DMA-mapping subsystem.

  The second part provides a complete redesign in ARM DMA-mapping
  subsystem.  The core implementation has been changed to use common
  struct dma_map_ops based infrastructure with the recent updates for
  new dma attributes merged in v3.4-rc2.  This allows to use more than
  one implementation of dma-mapping calls and change/select them on the
  struct device basis.  The first client of this new infractructure is
  dmabounce implementation which has been completely cut out of the
  core, common code.

  The last patch of this redesign update introduces a new, experimental
  implementation of dma-mapping calls on top of generic IOMMU framework.
  This lets ARM sub-platform to transparently use IOMMU for DMA-mapping
  calls if one provides required IOMMU hardware.

  For more information please refer to the following thread:
		http://www.spinics.net/lists/arm-kernel/msg175729.html

  The last patch merges changes from both updates and provides a
  resolution for the conflicts which cannot be avoided when patches have
  been applied on the same files (mainly arch/arm/mm/dma-mapping.c)."
