Merge tag 'topic/drm-misc-2016-06-07' of git://anongit.freedesktop.org/drm-intel into drm-next

Browse Source 
As promised, piles of prep work all around:
- drm_atomic_state rework, prep for nonblocking commit helpers
- fence patches from Gustavo and Christian to prep for atomic fences and
  some cool work in ttm/amdgpu from Christian
- drm event prep for both nonblocking commit and atomic fences
- Gustavo seems on a crusade against the non-kms-native version of the
  vblank functions.
- prep work from Boris to nuke all the silly ->best_encoder
  implementations we have (we really only need that for truly dynamic
  cases like dvi-i vs dvi-d or dp mst selecting the right transcoder on
  intel)
- prep work from Laurent to rework the format handling functions
- and few small things all over
