Merge tag 'v3.4-rc3' into drm-intel-next-queued

Backmerge Linux 3.4-rc3 into drm-intel-next to resolve a few things
that conflict/depend upon patches in -rc3:
- Second part of the Sandybridge workaround series - it changes some
  of the same registers.
- Preparation for Chris Wilson's fencing cleanup - we need the fix
  from -rc3 merged before we can move around all that code.
- Resolve the gmbus conflict - gmbus has been disabled in 3.4 again,
  but should be enabled on all generations in 3.5.
