Merge branch 'drm-nouveau-next' of git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-core-next

Ben was distracted:

"Apologies for being really late with this, feel free to bash me in the
future so I remember on time!

Overview:
- improvements to reclocking (especially memory) on nva3+
- kepler accel support (if you have blob ucode)
- better inter-channel synchronisation on nv84+
- async ttm buffer moves on nv84+ (earlier cards don't have a non-PGRAPH
engine that's useful)"

* 'drm-nouveau-next' of git://anongit.freedesktop.org/git/nouveau/linux-2.6: (60 commits)
