  drm/i915: Remove redundant test in error path.
  drm: Add a debug node for vblank state.
  drm: Avoid use-before-null-test on dev in drm_cleanup().
  drm/i915: Don't print to dmesg when taking signal during object_pin.
  drm: pin new and unpin old buffer when setting a mode.
  drm/i915: un-EXPORT and make 'intelfb_panic' static
  drm/i915: Delete unused, pointless i915_driver_firstopen.
  drm/i915: fix sparse warnings: returning void-valued expression
  drm/i915: fix sparse warnings: move 'extern' decls to header file
  drm/i915: fix sparse warnings: make symbols static
  drm/i915: fix sparse warnings: declare one-bit bitfield as unsigned
  drm/i915: Don't double-unpin buffers if we take a signal in evict_everything().
  drm/i915: Fix fbcon setup to align display pitch to 64b.
  drm/i915: Add missing userland definitions for gem init/execbuffer.
  i915/drm: provide compat defines for userspace for certain struct members.
  drm: drop DRM_IOCTL_MODE_REPLACEFB, add+remove works just as well.
  drm: sanitise drm modesetting API + remove unused hotplug
  drm: fix allowing master ioctls on non-master fds.
  drm/radeon: use locked rmmap to remove sarea mapping.
