Merge tag 'drm-fixes-for-v4.10-rc6-part-two' of git://people.freedesktop.org/~airlied/linux

Pull drm fixes from Dave Airlie:
 "This is the main request for rc6, since really the one earlier was the
  rc5 one :-)

  The main thing are the nouveau specific race fixes for the connector
  locking bug we fixed in -next and reverted here as it has quite large
  prereqs. These two fixes should solve the problem at that level and we
  can fix it properly in 4.11

  Otherwise i915 has a bunch of changes, one ABI change for GVT related
  stuff, some VC4 leak fixes, one core fence fix and some AMD changes,
  oh and one ast hang avoidance fix.

  Hoping it calms down around now"

* tag 'drm-fixes-for-v4.10-rc6-part-two' of git://people.freedesktop.org/~airlied/linux: (25 commits)
