    Hawaii support

  Nouveau:
    dynamic pm code infrastructure reworked, does nothing major yet
    GK208 modesetting support
    MSI fixes, on by default again
    PMPEG improvements
    pageflipping fixes

  GMA500:
    minnowboard SDVO support

  VMware:
    misc fixes

  MSM:
    prime, plane and rendernodes support

  Tegra:
    rearchitected to put the drm driver into the drm subsystem.
    HDMI and gr2d support for tegra 114 SoC

  QXL:
    oops fix, and multi-head fixes

  DRM core:
    sysfs lifetime fixes
    client capability ioctl
    further cleanups to device midlayer
    more vblank timestamp fixes"
