Merge tag 'drm-fixes-for-4.8-rc7' of git://people.freedesktop.org/~airlied/linux

Pull exynos and one stable ABI fix from Dave Airlie:
 "One important drm 32/64 ABI fix came in so I'll dequeue what I have,
  the rest is just exynos runtime pm fixes, but the net removal of code
  seems like a win to me.

  I'm going to be sporadic this week due to school holidays, so if
  anything urgent turns up, Daniel will take care of it"

* tag 'drm-fixes-for-4.8-rc7' of git://people.freedesktop.org/~airlied/linux:
