Pull drm fixes from Dave Airlie:
 "I didn't want these to wait for stable cycle.

  The nouveau and radeon ones are the same problem, where the runtime pm
  stuff broke non-runtime pm managed secondary GPUs.

  The udl fix is for an oops on unplug, and the i915 fix is for a
  regression on Sandybridge even though it may break haswell (regression
  wins)"

Daniel Vetter comments:
 "My apologies for the i915 regression fumble, that thing somehow fell
  through the cracks here for almost half a year :( Imo that's more than
  enough flailing to just go ahead with the revert, and the re-broken
  hsw should get peoples attention ..."
