Merge tag 'v3.7-rc2' into drm-intel-next-queued

Linux 3.7-rc2

Backmerge to solve two ugly conflicts:
- uapi. We've already added new ioctl definitions for -next. Do I need to say more?
- wc support gtt ptes. We've had to revert this for snb+ for 3.7 and
  also fix a few other things in the code. Now we know how to make it
  work on snb+, but to avoid losing the other fixes do the backmerge
  first before re-enabling wc gtt ptes on snb+.

And a few other minor things, among them git getting confused in
intel_dp.c and seemingly causing a conflict out of nothing ...
