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

Summary:
- GK110/GK208 acceleration
- loads more work towards pm, though, still behind a disable wall for now
- error reporting improvements from both Ilia and myself
- more old-school overlay improvements from Ilia
- misc other bits and pieces

* 'drm-nouveau-next' of git://anongit.freedesktop.org/git/nouveau/linux-2.6: (68 commits)
  drm/nouveau: call drm_vblank_cleanup() earlier
  drm/nouveau: create base display from common code
  drm/nv50/gr: print mpc trap name when it's not an mp trap
  drm/nv50/gr: update list of mp errors, make it a bitfield
  drm/nv50/gr: add more trap names to print on error
  drm/nouveau/devinit: lock/unlock crtc regs for all devices, not just pre-nv50
  drm/nouveau: hold mutex while syncing to kernel channel
  drm/nv50-/devinit: prevent use of engines marked as disabled by hw/vbios
  drm/nouveau/device: provide a way for devinit to mark engines as disabled
  drm/nouveau/devinit: tidy up the subdev class definition
  drm/nouveau/bar: tidy up the subdev and object class definitions
  drm/nouveau/instmem: tidy up the object class definition
  drm/nouveau/instmem: tidy up the subdev class definition
  drm/nouveau/pwr: implement a simple i2c stack
  drm/nouveau/pwr: have rd/wr32 routines clobber data instead of addr
  drm/nve0/fb: turn off some bits in 10f584 at init
  drm/nve0/fb/gddr5: merge a fix from ddr3 for one of the timing settings
  drm/nve0/fb/gddr5: yet another random 10f200 bit
  drm/nvc0-/fb: hook up skeleton interrupt handler
  drm/nve0/fb/gddr5: more 10f200 stuff
