Shawn Guo b632a30e8b ARM: remove unused arch_decomp_wdog()
With ARCH_HAS_DECOMP_WDOG removed from arch/arm/boot/compressed/decompress.c,
all the arch_decomp_wdog() definition at platform level is unneeded.
Remmove it.

Linus Torvalds 0e51793e16 Merge branch 'for-linus' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM updates from Russell King:
 "This is the first chunk of ARM updates for this merge window.
  Conflicts are expected in two files - asm/timex.h and
  mach-integrator/integrator_cp.c.  Nothing particularly stands out more
  than anything else.

  Most of the growth is down to the opcodes stuff from Dave Martin,
  which is countered by Rob's patches to use more of the asm-generic
  headers on ARM."

(A few more conflicts grew since then, but it all looked fairly trivial)

Linus Torvalds 9cd11c0c47 ARM: soc: multiplatform enablement
This is a pretty significant branch. It's the introduction of the
 first multiplatform support on ARM, and with this (and the later
 branch) merged, it is now possible to build one kernel that contains
 support for highbank, vexpress, mvebu, socfpga, and picoxcell. More
 platforms will be convered over in the next few releases.
 
 Two critical last things had to be done for this to be practical and
 possible:
 * Today each platform has its own include directory under
   mach-<mach>/include/mach/*, and traditionally that is where a lot of
   driver/platform shared definitions have gone, such as platform data
   structures. They now need to move out to a common location instead,
   and this branch moves a large number of those out to
   include/linux/platform_data.
 * Each platform used to list the device trees to compile for its
   boards in mach-<mach>/Makefile.boot.
 
 Both of the above changes will mean that there are some merge
 conflicts to come (and some to resolve here). It's a one-time move and
 once it settles in, we should be good for quite a while. Sorry for the
 overhead.

Pull ARM platform updates from Russell King:
 "This covers platform stuff for platforms I have a direct interest in
  (iow, I have the hardware).  Essentially:
   - as we no longer support any other Acorn platforms other than RiscPC
     anymore, we can collect all that code into mach-rpc.
   - convert Acorn expansion card stuff to use IRQ allocation functions,
     and get rid of NO_IRQ from there.
   - cleanups to the ebsa110 platform to move some private stuff out of
     its header files.
   - large amount of SA11x0 updates:
   - conversion of private DMA implementation to DMA engine support
     (this actually gives us greater flexibility in drivers over the old
     API.)
   - re-worked ucb1x00 updates - convert to genirq, remove sa11x0
     dependencies, fix various minor issues
   - move platform specific sa11x0 framebuffer data into platform files
     in arch/arm instead of keeping this in the driver itself
   - update sa11x0 IrDA driver for DMA engine, and allow it to use DMA
     for SIR transmissions as well as FIR
   - rework sa1111 support for genirq, and irq allocation
   - fix sa1111 IRQ support so it works again
   - use sparse IRQ support

  After this, I have one more pull request remaining from my current
  set, which I think is going to be the most problematical as it
  generates 8 conflicts."

Russell.

Russell King 65f2e753f1 Revert "ARM: sa11x0: Implement autoloading of codec and codec pdata for mcp bus."
This reverts commit 5dd7bf59e0.

Conflicts:

	scripts/mod/file2alias.c

This change is wrong on many levels.  First and foremost, it causes a
regression.  On boot on Assabet, which this patch gives a codec id of
'ucb1x00', it gives:

	ucb1x00 ID not found: 1005

0x1005 is a valid ID for the UCB1300 device.

Secondly, this patch is way over the top in terms of complexity.  The
only device which has been seen to be connected with this MCP code is
the UCB1x00 (UCB1200, UCB1300 etc) devices, and they all use the same
driver.  Adding a match table, requiring the codec string to match the
hardware ID read out of the ID register, etc is completely over the top
when we can just read the hardware ID register.

Russell King f408c985ce GPIO: sa1100: implement proper gpiolib gpio_to_irq conversion
The existing gpio_to_irq() implementation on sa1100 only translates
validly for internal GPIOs.  Since this sub-arch enables GPIOLIB
support, this results in buggy translations for non-internal GPIOs.

Get rid of the private gpio_to_irq() implementation, replacing it
with the .to_irq method in the sa1100 gpio chip instead.

We only need to set the system up for a soft-restart if we're going to
be doing a soft-restart.  Provide a new function (soft_restart()) which
does the setup and final call for this, and make platforms use it.
Eliminate the call to setup_restart() from the default handler.

This means that platforms arch_reset() function is no longer called with
the page tables prepared for a soft-restart, and caches will still be
enabled.
