  I pretty much froze major pulls at -rc5/6 time, and haven't had much

  Lots of changes all over, big internal header cleanup to make it clear

  core:
        atomic prep work,
        vblank rework changes, allows immediate vblank disables
        major header reworking and cleanups to better delinate legacy

        ppc64 caching fixes

  radeon:
        userptr support,
        uvd for old asics,
        reset rework for fence changes
        better buffer placement changes,
        dpm ...
