Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux
Pull drm fixes from Dave Airlie:
"This is the final set of fixes for -rc8, just a few i915 and one
vmwgfx ones.
I'm off on holidays for a week, so if anything shows up for fixes I've
asked Daniel or Sean Paul to herd it in the right direction"
[ The additional etnaviv fixes were already herded towards me as seen in
my previous pull - Linus ]
* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
drm/vmwgfx: Free hash table allocated by cmdbuf managed res mgr
drm/i915: Disable EXEC_OBJECT_ASYNC when doing relocations
drm/i915: Hold struct_mutex for per-file stats in debugfs/i915_gem_object
drm/i915: Retire the VMA's fence tracker before unbinding
