Pull drm fixes from Dave Airlie:
 "This is just a regular fixes pull, mostly nouveau and i915, the i915
  ones fix RC6 on Sandybridge after suspend/resume, which I think people
  have be wanting for quite a while!

  Now you shouldn't wish for more patches, as the new mutex/reservation
  code found a number of problems with the qxl driver, and it currently
  makes lockdep angry, I'm working on a set of fixes for it, but its a
  bit large, I'll submit them separately later today or tomorrow once
  I've banged on them a bit more, just warning you in advance :-)"

Yeah, I'm definitely over the whole "wish for more patches" thing.
