Merge commit 'Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux'
This backmerges Linus' merge commit of the latest drm-fixes pull: commit 549f3a1218ba18fcde11ef0e22b07e6365645788 Merge: 42577ca 058ca4a Author: Linus Torvalds <torvalds@linux-foundation.org> Date: Tue Jul 23 15:47:08 2013 -0700 Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux We've accrued a few too many conflicts, but the real reason is that I want to merge the 100% solution for Haswell concurrent registers writes into drm-intel-next. But that depends upon the 90% bandaid merged into -fixes: commit a7cd1b8fea2f341b626b255d9898a5ca5fabbf0a Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Fri Jul 19 20:36:51 2013 +0100 drm/i915: Serialize almost all register access Also, we can roll up on accrued conflicts. Usually I'd backmerge a tagged -rc, but I want to get this done before heading off to vacations next week ;-) Conflicts: drivers/gpu/drm/i915/i915_dma.c drivers/gpu/drm/i915/i915_gem.c v2: For added hilarity we have a init sequence conflict around the gt_lock, so need to move that one, too.
