Merge tag 'topic/drm-misc-2015-08-13' of git://anongit.freedesktop.org/drm-intel into drm-next

Final drm-misc pull for 4.3:
- fbdev emulation Kconfig option for everyone thanks to Archit. It's not
  everything yet bit this is fairly tricky since it spawns all drivers.
- vgaarb & vgaswitcheroo polish from Thierry
- some drm_irq.c cleanups (Thierry)
- struct_mutex crusade from me
- more fbdev panic handling removal
- various things all over in drm core&helpers
