Merge remote-tracking branch 'airlied/drm-next' into drm-intel-next-queued
Backmerge because:
- Maarten needs latest atomic patches from drm-misc.
- Lionel needs the color manager core patch from drm-misc.
- Ander extracted intel_dpll_mgr.c, we need a backmerge to avoid git
losing track of things too often (right now it seems ok due to
cherry-picks).
- Tvrtko needs a stable baseline to apply some large-scale renaming
patches to i915 GEM code.
