Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux

Pull drm updates from Dave Airlie:
 "One of the smaller drm -next pulls in ages!

  Ben (nouveau) has a rewrite in progress but we decided to leave it
  stew for another cycle, so just some fixes from him.

   - radeon: lots of documentation work, fixes, more ring and locking
     changes, pcie gen2, more dp fixes.
   - i915: haswell features, gpu reset fixes, /dev/agpgart removal on
     machines that we never used it on, more VGA/HDP fix., more DP fixes
   - drm core: cleanups from Daniel, sis 64-bit fixes, range allocator
     colouring.

  but yeah fairly quiet merge this time, probably because I missed half
  of it!"

Trivial add-add conflict in include/linux/pci_regs.h
