Merge branch 'drm-nouveau-next' of git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-next
- Various fixes that make surviving concurrent piglit more possible. - Buffer object deletion no longer synchronous - Context/register initialisation updates that have been reported to solve some stability issues (particularly on some problematic GF119 chips) - Kernel side support for VP2 video decoding engines * 'drm-nouveau-next' of git://anongit.freedesktop.org/git/nouveau/linux-2.6: (44 commits) drm/nvd0-/disp: handle case where display engine is missing/disabled drm/gr/nvc0-: merge nvc0/nve0 ucode, and use cpp instead of m4 drm/nouveau/bsp/nv84: initial vp2 engine implementation drm/nouveau/vp/nv84: initial vp2 engine implementation drm/nouveau/core: xtensa engine base class implementation drm/nouveau/vdec: fork vp3 implementations from vp2 drm/nouveau/core: move falcon class to engine/ drm/nouveau/kms: don't fail if there's no dcb table entries drm/nouveau: remove limit on gart drm/nouveau/vm: perform a bar flush when flushing vm drm/nvc0/gr: cleanup register lists, and add nvce/nvcf to switches drm/nvc8/gr: update initial register/context values drm/nvc4/gr: update initial register/context values drm/nvc1/gr: update initial register/context values drm/nvc3/gr: update initial register/context values drm/nvc0/gr: update initial register/context values drm/nvd9/gr: update initial register/context values drm/nve4/gr: update initial register/context values drm/nvc0-/gr: bump maximum gpc/tpc limits drm/nvf0/gr: initial register/context setup ...
