Merge remote branch 'nouveau/drm-nouveau-next' of /ssd/git/drm-nouveau-next into drm-fixes
* 'nouveau/drm-nouveau-next' of /ssd/git/drm-nouveau-next:
drm/nouveau: fix gpu page faults triggered by plymouthd
drm/nouveau: greatly simplify mm, killing some bugs in the process
drm/nvc0: enable protection of system-use-only structures in vm
drm/nv40: initialise 0x17xx on all chipsets that have it
drm/nv40: make detection of 0x4097-ful chipsets available everywhere
