Merge branch 'linux-3.17' of git://anongit.freedesktop.org/git/nouveau/linux-2.6

Pull nouveau drm updates from Ben Skeggs:
 "Apologies for not getting this done in time for Dave's drm-next merge
  window.  As he mentioned, a pre-existing bug reared its head a lot
  more obviously after this lot of changes.  It took quite a bit of time
  to track it down.  In any case, Dave suggested I try my luck by
  sending directly to you this time.

  Overview:

   - more code for Tegra GK20A from NVIDIA - probing, reclockig
   - better fix for Kepler GPUs that have the graphics engine powered
     off on startup, method courtesy of info provided by NVIDIA
   - unhardcoding of a bunch of graphics engine setup on
     Fermi/Kepler/Maxwell, will hopefully solve some issues people have
     noticed on higher-end models
   - support for "Zero Bandwidth Clear" on Fermi/Kepler/Maxwell, needs
     userspace support in general, but some lucky apps will benefit
     automagically
   - reviewed/exposed the full object APIs to userspace (finally), gives
     it access to perfctrs, ZBC controls, various events.  More to come
     in the future.
   - various other fixes"
