Merge git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile
Pull tile arch changes from Chris Metcalf:
"These are some minor new feature work and other changes that didn't
merit getting pushed up after the 3.9 merge window closed.
There should be a lot more activity in the 3.11 merge window"
