Pull drm update from Dave Airlie:
 "This pull just contains a forward of the Intel fixes from Daniel.

  The only annoyance is the RC6 enable, which really should have made
  -next, but since Ubuntu are shipping it I reckon its getting a good
  testing now by the time 3.4 comes out.

  The pull from Daniel contains his pull message to me:

    "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
      - sprite fix from Jesse"

Let's see if the "enable RC6 on sandybridge" finally works and sticks.
I've been enabling it by hand (i915.i915_enable_rc6=1) for several
months on my Macbook Air, and it definitely makes a difference (and has
worked for me).  But every time we enabled it before it showed some odd
hw buglet for *somebody*.

This time it's all good, I'm sure.

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.

When comparing two pages read from different legs of a mirror, only
compare the bytes that were read, not the whole page.

In most cases we read a whole page, but in some cases with
bad blocks or odd sizes devices we might read fewer than that.

This bug has been present "forever" but at worst it might cause
a report of two many mismatches and generate a little bit
extra resync IO, so there is no need to back-port to -stable

When create a raid5 using assume-clean and echo check or repair to
sync_action.Then component disks did not operated IO but the raid
check/resync faster than normal.
Because the judgement in function analyse_stripe():
		if (do_recovery ||
		    sh->sector >= conf->mddev->recovery_cp)
			s->syncing = 1;
		else
			s->replacing = 1;
When check or repair,the recovery_cp == MaxSectore,so syncing equal zero
not one.

It really only needs two simple defines from asm-generic, so just use
those instead.

Commit bf4289cb ("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.

Pull HSI (High Speed Synchronous Serial Interface) framework from Carlos Chinea:
 "The High Speed Synchronous Serial Interface (HSI) is a serial
  interface mainly used for connecting application engines (APE) with
  cellular modem engines (CMT) in cellular handsets.

  The framework is currently being used for some people and we would
  like to see it integrated into the kernel for 3.3.  There is no HW
  controller drivers in this pull, but some people have already some of
  them pending which they would like to push as soon as this integrated.
  I am also working on the acceptance for an TI OMAP one, based on a
  compatible legacy version of the interface called SSI."

Ok, so it didn't get into 3.3, but here it is pulled into 3.4.

Several people piped up to say "yeah, we want this".

  not the use case that was not supposed (make cscope)."

Pull cpumask cleanups from Rusty Russell:
 "(Somehow forgot to send this out; it's been sitting in linux-next, and
  if you don't want it, it can sit there another cycle)"

I'm a sucker for things that actually delete lines of code.

Fix up trivial conflict in arch/arm/kernel/kprobes.c, where Rusty fixed
a user of &cpu_online_map to be cpu_online_mask, but that code got
deleted by commit b21d55e9 ("ARM: 7332/1: extract out code patch

Builds of the MIPS platform ip32_defconfig fails as of commit
0195c002 ("Merge tag 'split-asm_system_h ...") because MIPS xchg()
macro uses BUILD_BUG_ON and it was moved in commit b81947c6
("Disintegrate asm/system.h for MIPS").

The root cause is that the system.h split wasn't tested on a baseline
with commit 6c03438e ("kernel.h: doesn't explicitly use bug.h, so
don't include it.")

Since this file uses BUG code in several other places besides the xchg
call, simply make the inclusion explicit.

Totally unexpected that this regressed. Luckily it sounds like we just
need to have dmar disable on the igfx, not the entire system. At least
that's what a few days of testing between Tony Vroon and me indicates.
