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

    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. Spotted by Jani Nikula.
