Merge branch 'drm-next' of git://people.freedesktop.org/~dvdhrm/linux into drm-next
This is the 3rd respin of the drm-anon patches. They allow module unloading, use
the pin_fs_* helpers recommended by Al and are rebased on top of drm-next. Note
that there are minor conflicts with the "drm-minor" branch.
* 'drm-next' of git://people.freedesktop.org/~dvdhrm/linux:
drm: init TTM dev_mapping in ttm_bo_device_init()
drm: use anon-inode instead of relying on cdevs
drm: add pseudo filesystem for shared inodes
