avr32: fix build failures from mis-naming of atmel_nand.h

Commit bf4289cba02b ("ATMEL: fix nand ecc support") indicated that it
wanted to "Move platform data to a common header
include/linux/platform_data/atmel_nand.h" and the new header even had
re-include protectors with:

    #ifndef __ATMEL_NAND_H__

However, the file that was added was simply called atmel.h
and this caused avr32 defconfig to fail with:

  In file included from arch/avr32/boards/atstk1000/setup.c:22:
  arch/avr32/mach-at32ap/include/mach/board.h:10:44: error: linux/platform_data/atmel_nand.h: No such file or directory

  make[2]: *** [arch/avr32/boards/atstk1000/setup.o] Error 1

It seems the scope of the file contents will expand beyond
just nand, so ignore the original intention, and fix up the
users who reference the bad name with the _nand suffix.

blackfin: fix cmpxchg build fails from system.h fallout

parisc: fix missing cmpxchg file error from system.h split

Commit b4816afa3986 ("Move the asm-generic/system.h xchg()
implementation to asm-generic/cmpxchg.h") introduced the concept of
asm/cmpxchg.h but the parisc arch never got one.  Fork the cmpxchg
content out of the asm/atomic.h file to create one.

Some minor whitespace fixups were done on the block of code that created
the new file.

firewire: restore the device.h include in linux/firewire.h

Commit 313162d0b838 ("device.h: audit and cleanup users in main include
dir") exchanged an include <linux/device.h> for a struct *device but in
actuality I misread this file when creating 313162d and it should have
remained an include.

There were no build regressions since all consumers were already getting
device.h anyway, but make it right regardless.

Pull dma-buf prime support from Dave Airlie:
 "This isn't a majorly urgent thing to have, but we'd like to set the
  stage for working on dma-buf support in the drm drivers for the next
  merge window, so I'd like to push in the initial submission now so
  people have something that we can build on top of.  The code just
  introduces the user interface and internal helper functions for
  drivers to use.

  We have driver support under development for i915, nouveau, udl on x86
  and exynos, omapdrm on arm, which we would be aiming for the next
  merge window."

In the -rc1 announcement I asked for people who would use this to
comment on it, and got severa "Yes please" from people for this and for
HSI (that I merged earlier).

So far crickets on pohmelfs and the DMA-mapping infrastructure.

drm: Validate requested virtual size against allocated fb size

mplayer -vo fbdev tries to create a screen that is twice as tall as the
allocated framebuffer for "doublebuffering". By default, and all in-tree
users, only sufficient memory is allocated and mapped to satisfy the
smallest framebuffer and the virtual size is no larger than the actual.
For these users, we should therefore reject any userspace request to
create a screen that requires a buffer larger than the framebuffer
originally allocated.

From Daniel Vetter:

"A few patches for 3.4, major part is 3 regression fixes:
- ppgtt broke hibernate on snb/ivb. Somehow our QA claims that it still
 works, which is why this has not been caught earlier.
- ppgtt flails in combination with dmar. I kinda expected this one :(
- fence handling bugfix for gen2/3. Iirc this one is about a year old, fix
 curtesy Chris Wilson. I've created an shockingly simple i-g-t test to
 catch this in the future.

Wrt regressions I've just got a report that gmbus (newly enabled again in
3.4) is a bit noisy. I'm looking into this atm.

Also included are the rc6 enable patches for snb from Eugeni. I wanted to
include these in the main 3.4 pull but screwed it up. Please hit me. Imo
these kind of patches really should go in before -rc1, but in thise case
rc6 has brought us tons of press and guinea pigs^W^W testers and ubuntu is
already running with it. So I estimate a pretty small chance for this to
blow up.

And some smaller things:
- two minor locking snafus
- server gt2 ivb pciid
- 2 patches to sanitize the register state left behind by the bios some
 more
- 2 new quirk entries
- cs readback trick against missed IRQs from ivb also enabled on snb
