Merge tag 'topic/drm-misc-2016-05-04' of git://anongit.freedesktop.org/drm-intel into drm-next

Ofc I promise just a few leftovers for drm-misc and somehow it's the
biggest pull. But really mostly trivial stuff:
- MAINTAINERS updates from Emil
- rename async to nonblock in atomic_commit to avoid the confusion between
  nonblocking ioctl and async flip (= not vblank synced), from Maarten.
  Needs to be regened with newer drivers, but probably only after -rc1 to
  catch them all.
- actually lockless gem_object_free, plus acked driver conversion patches.
  All the trickier prep stuff already is in drm-next.
- Noralf's nice work for generic defio support in our fbdev emulation.
  Keeps the udl hack, and qxl is tested by Gerd.
