Merge tag 'v3.10' into drm-intel-fixes

Backmerge Linux 3.10 to get at

    drm/i915: Restore fences after resume and GPU resets

That commit is not in my current -fixes pile since that's based on my
-next queue for 3.11. And the above mentioned fix was merged really
late into 3.10 (and blew up, bad me) so was on a diverging branch.

Option B would have been to rebase my current pile of fixes onto
Dave's drm-fixes branch. But since some of the patches here are a bit
tricky I've decided not to void all the testing by moving over the
entire merge window.
