sound-unstable git tree always contains the sound git tree master
branch, so everything is there basically.  But it'd be better to merge
this onto 3.8-final.  Just pull Linus tree v3.8 tag on sound-unstable
git tree:

	% git pull \
          git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux \
	  v3.8
