[pull] drm-intel-fixes for 3.4

[Daniel Vetter <daniel@ffwll.ch>]

Hi Dave,

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

Yours, Daniel
