Highlights:
- Imre's for_each_sg_pages rework (now also with the stolen mem backed
  case fixed with a hack) plus the drm prime sg list coalescing patch from
  Rahul Sharma. I have some follow-up cleanups pending, already acked by
  Andrew Morton.
- Some prep-work for the crazy no-pch/display-less platform by Ben.
- Some vlv patches, by far not all (Jesse et al).
- Clean up the HDMI/SDVO #define confusion (Paulo)
- gen2-4 vblank fixes from Ville.
- Unclaimed register warning fixes for hsw (Paulo). More still to come ...
- Complete pageflips which have been stuck in a gpu hang, should prevent
  stuck gl compositors (Ville).
- pm patches for vt-switchless resume (Jesse). Note that the i915 enabling
  is not (yet) included, that took a bit longer to settle. PM patches are
  acked by Rafael Wysocki.
- Minor fixlets all over from various people.
