The basic idea behind the fast-path is that we can tile/detile in software faster than going through the GTT or waiting on the blitter to do it for us. This series adds the capability of doing it in the other direction. The work was started by Sasmita Patra who was interning with us for a little while. It's been sitting around in my personal repo for over a month so I figured I should fix it up and send it out. I went ahead and left Sasmita as the author with my Signed-off-by because.
