Pull drm intel fixes from Daniel Vetter:
 "I delayed my -fixes pull a bit hoping that I could include a fix for
  the dp mst stuff but looks a bit more nasty than that.  So just 3
  other regression fixes, one 4.2 other two cc: stable"

* tag 'drm-intel-fixes-2015-07-31' of git://anongit.freedesktop.org/drm-intel:
  drm/i915: Declare the swizzling unknown for L-shaped configurations
  drm/i915: Mark PIN_USER binding as GLOBAL_BIND without the aliasing ppgtt
  drm/i915: Replace WARN inside I915_READ64_2x32 with retry loop
