xf86-video-vmware/U_0004-vmwgfx-Get-rid-of-device-specific-DMA-code.patch
Stefan Dirsch e81dc8bbd0 - U_0001-vmwgfx-update-for-XA-API-changes.patch 
- U_0002-vmwgfx-Avoid-HW-operations-when-not-master.patch
  * Note that for DRI2, a dri2_copy_region becomes a NOP when not master.
    Additionally, all dri2 operations that lead to a potential kernel
    access will return FALSE.
- U_0003-vmwgfx-Implement-textured-video-completely-on-top-of.patch
  * Remove device-specific hacks. This may increase resource usage a little
    on old hardware revisions, but we don't need separate code paths on
    different hardware revisions.
- U_0004-vmwgfx-Get-rid-of-device-specific-DMA-code.patch
  * It's rarely used and things seem to work well enough on top of XA.
- U_0005-vmwgfx-handle-changes-of-DamageUnregister-API-in-1.1.patch
  * Fix is inspired from the intel driver.
