[Daniel Vetter <daniel.vetter@ffwll.ch>]

Hi Dave,

drm-intel-next-2016-08-08:
- refactor ddi buffer programming a bit (Ville)
- large-scale renaming to untangle naming in the gem code (Chris)
- rework vma/active tracking for accurately reaping idle mappings of shared
  objects (Chris)
- misc dp sst/mst probing corner case fixes (Ville)
- tons of cleanup&tunings all around in gem
- lockless (rcu-protected) request lookup, plus use it everywhere for
  non(b)locking waits (Chris)
- pipe crc debugfs fixes (Rodrigo)
- random fixes all over
drm-intel-next-2016-07-25:
- more engine code unification (Tvrtko)
- reorganize rps&rc6 setup (Chris Wilson)
- hotplug polling when in deep rpm states, especially fixes vls (Lyude)
- mocs fix for bxt (Imre)
- convert i915 request to use dma fences (Chris)
- prep work for lockless i915 requests/fences (needed for full sync integration)
  from Chris Wilson
- wait for external rendering/fences attached to dma_bufs (Chris)
- tons of small bugfixes all over

Note also contains a backmerge (git got confused), but when you've pulled
in all pending pulls (there's a few now) I want to do another backmerge to
get at the latest fences stuff from Gustavo.

Cheers, Daniel
