SVN rev 207067 on 2010-04-22 18:44:23Z by rnoland
re-write scatter gather memory allocation yet again...
This time, abandon the use of busdma and start interacting with the VM
system directly. Make use of the new kmem_alloc_attr() which allows us
to easily allocate non-contiguous pages to back the GART table. This
should help a lot when starting or restarting X after the system has
been running for a while and memory has become fragmented.
MFC after: 2 weeks
