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

Pull drm fixes from Dave Airlie:
 "Fix for radeon nomodeset regression, old radeon interface cliprects
  fix, 2 qxl crasher fixes, and a couple of minor cleanups.

  I may have a new AMD hw support branch next week, its one of those
  doesn't affect anything existing just adds new support, I'll see how
  it shapes up and I might ask you to take it, just thought I'd warn in
  advance."

* 'drm-next' of git://people.freedesktop.org/~airlied/linux:
  drm/radeon: restore nomodeset operation (v2)
  qxl: fix bug with object eviction and update area
  drm/qxl: drop active_user_framebuffer as its unneeded
  qxl: drop unused variable.
  drm/qxl: fix ioport interactions for kernel submitted commands.
  drm: remove unused wrapper macros
  drm/radeon: check incoming cliprects pointer
