Pull ARM SoC platform changes from Olof Johansson:
 "This branch contains mostly additions and changes to platform
  enablement and SoC-level drivers.  Since there's sometimes a
  dependency on device-tree changes, there's also a fair amount of
  those in this branch.

  Pieces worth mentioning are:

   - Mbus driver for Marvell platforms, allowing kernel configuration
     and resource allocation of on-chip peripherals.
   - Enablement of the mbus infrastructure from Marvell PCI-e drivers.
   - Preparation of MSI support for Marvell platforms.
   - Addition of new PCI-e host controller driver for Tegra platforms
   - Some churn caused by sharing of macro names between i.MX 6Q and 6DL
     platforms in the device tree sources and header files.
   - Various suspend/PM updates for Tegra, including LP1 support.
   - Versatile Express support for MCPM, part of big little support.
   - Allwinner platform support for A20 and A31 SoCs (dual and quad
     Cortex-A7)
   - OMAP2+ support for DRA7, a new Cortex-A15-based SoC.

  The code that touches other architectures are patches moving MSI
  arch-specific functions over to weak symbols and removal of
  ARCH_SUPPORTS_MSI, acked by PCI maintainers"

Pull ARM SoC cleanups from Olof Johansson:
 "This branch contains code cleanups, moves and removals for 3.12.

  There's a large number of various cleanups, and a nice net removal of
  13500 lines of code.

  Highlights worth mentioning are:

   - A series of patches from Stephen Boyd removing the ARM local timer
     API.
   - Move of Qualcomm MSM IOMMU code to drivers/iommu.
   - Samsung PWM driver cleanups from Tomasz Figa, removing legacy PWM
     driver and switching over to the drivers/pwm one.
   - Removal of some unusued auto-generated headers for OMAP2+ (PRM/CM).

  There's also a move of a header file out of include/linux/i2c/ to
  platform_data, where it really belongs.  It touches mostly ARM
  platform code for include changes so we took it through our tree"

   automatically ignored by the CPU).

 - Remove BogoMIPS reporting (not relevant, it's just the timer
   frequency).

It appears that gcc may put some code in ".text.unlikely" or
".text.hot" sections.  Right now those aren't accounted for in unwind
tables.  Add them.

I found some docs about this at:
  http://gcc.gnu.org/onlinedocs/gcc-4.6.2/gcc.pdf

Without this, if you have slub_debug turned on, you can get messages
that look like this:
  unwind: Index not found 7f008c50
