Merge remote-tracking branch 'airlied/drm-next' into drm-intel-next-queued
Pull in Dave's drm-next pull request to have a clean base for 4.6. Also, we need the various atomic state extensions Maarten recently created. Conflicts are just adjacent changes that all resolve to nothing in git diff. Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>
