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

* 'drm-nouveau-next' of git://anongit.freedesktop.org/git/nouveau/linux-2.6: (50 commits)
  drm/nv50: flesh out ZCULL init and match nvidia on later chipsets
  drm/nv50: support for compression
  drm/nv50-nvc0: delay GART binding until move_notify time
  drm/nouveau: rename nouveau_vram to nouveau_mem
  drm/nvc0: allow creation of buffers with any non-compressed memtype
  drm/nv50-nvc0: unmap buffers from the vm when they're evicted
  drm/nv50-nvc0: move vm bind/unbind to move_notify hook
  drm/nv50-nvc0: restrict memtype to those specified at creation time
  drm/nouveau: pass domain rather than ttm flags to gem_new()
  drm/nv50: simplify bo moves now that they're all through the vm
  drm/nouveau: remove no_vm/mappable flags from nouveau_bo
  drm/nouveau: Fix pageflip event
  drm/nouveau/vbios: parse more gpio tag bits from connector table
  drm/nouveau: decode PFIFO DMA_PUSHER error codes
  drm/nv50: fix typos in CCACHE error reporting
  drm/nvc0: support for sw methods + enable page flipping
  drm/nv50: enable page flipping
  drm/nv50-nvc0: activate/update ds channel's framebuffer on modesets
  drm/nv50-nvc0: initialise display sync channels
  drm/nv50-nvc0: precalculate some fb state when creating them
