Merge commit '5359533801e3dd3abca5b7d3d985b0b33fd9fe8b' into drm-core-next
This commit changed an internal radeon structure, that meant a new driver in -next had to be fixed up, merge in the commit and fix up the driver. Also fixes a trivial nouveau merge. Conflicts: drivers/gpu/drm/nouveau/nouveau_mem.c
