I dont think this was Sashkio's fault; this doesn't apply cleanly to
anything other than mm-unstable with my patches first reverted. I
first tried an mm-stable base but my code is now dependent on some
code in mm-unstable. As Andrew noted, I should have requested that he
pull the patches from mm-unstable before resending them.
