Adam Jackson ab1324774d * Tue Mar 03 2009 Adam Jackson <ajax@redhat.com> 1.6.0-4 
- xserver-1.6.0-selinux-raw.patch: Deal in raw contexts, to avoid paying
  the price for setrans on every object.
- xserver-1.6.0-primary.patch: Try harder to figure out what the primary
  video device is on machines with multiple GPUs.
- xserver-1.6.0-selinux-destroy.patch: Don't bother relabeling objects that
  are on the way to destruction.
