Merge tag 'drm-intel-fixes-2014-04-04' of git://anongit.freedesktop.org/drm-intel into drm-next
Merge window -fixes pull request as usual. Well, I did sneak in Jani's
drm_i915_private_t typedef removal, need to have fun with a big sed job
too ;-)
Otherwise:
- hdmi interlaced fixes (Jesse&Ville)
- pipe error/underrun/crc tracking fixes, regression in late 3.14-rc (but
not cc: stable since only really relevant for igt runs)
- large cursor wm fixes (Chris)
- fix gpu turbo boost/throttle again, was getting stuck due to vlv rps
patches (Chris+Imre)
- fix runtime pm fallout (Paulo)
- bios framebuffer inherit fix (Chris)
- a few smaller things
