Merge tag 'topic/core-stuff-2014-08-15' of git://anongit.freedesktop.org/drm-intel into drm-next

So small drm stuff all over for 3.18. Biggest one is the cmdline parsing
from Chris with a few fixes from me to make it work for stupid kernel
configs.

Plus the atomic prep series.

Tested for more than a week in -nightly and Ville/Imre indeed discovered
some fun which is now fixed (and i915 vblank patches postponed since the
fixups need this branch plus drm-intel-next merged together).

* tag 'topic/core-stuff-2014-08-15' of git://anongit.freedesktop.org/drm-intel:
  drm: Use the type of the array element when reallocating
  drm: Don't return 0 for a value used as a denominator
  drm: Docbook fixes
  drm/irq: Implement a generic vblank_wait function
  drm: Add a plane->reset hook
  drm: trylock modest locking for fbdev panics
  drm: Move ->old_fb from crtc to plane
  drm: Handle legacy per-crtc locking with full acquire ctx
  drm: Move modeset_lock_all helpers to drm_modeset_lock.[hc]
  drm: Add drm_plane/connector_index
  drm: idiot-proof vblank
  drm: Warn when leaking flip events on close
  drm: Perform cmdline mode parsing during connector initialisation
  video/fbdev: Always built-in video= cmdline parsing
  drm: Don't grab an fb reference for the idr
