Merge tag 'v3.13-rc3' into drm-intel-next-queued

Linux 3.13-rc3

I need a backmerge for two reasons:
- For merging the ppgtt patches from Ben I need to pull in the bdw
  support.
- We now have duplicated calls to intel_uncore_forcewake_reset in the
  setup code to due 2 different patches merged into -next and 3.13.
  The conflict is silen so I need the merge to be able to apply
  Deepak's fixup patch.

Conflicts:
	drivers/gpu/drm/i915/intel_display.c

Trivial conflict, it doesn't even show up in the merge diff.
