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

Main pull for 3.19.  I may have another pull in a few days with some
mdp5 bits (and hopefully mdp5 atomic), but I figured there was no need
to hold up what we have already.  Main highlights so far:

1) a4xx gpu support (userspace gallium bits on mesa master)
2) mdp4/hdmi/core bits for atomic helpers.  Still missing mdp5
conversion, main hold up there is current hard-coded mixer setup isn't
clever enough to deal with disabling primary plane while crtc active.
3) various other misc cleanup/fixes/etc..
