Merge branch 'stable' of git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile
Pull arch/tile bug fixes from Chris Metcalf:
"This includes Paul Gortmaker's change to fix the <asm/system.h>
disintegration issues on tile, a fix to unbreak the tilepro ethernet
driver, and a backlog of bugfix-only changes from internal Tilera
development over the last few months.
They have all been to LKML and on linux-next for the last few days.
The EDAC change to MAINTAINERS is an oddity but discussion on the
linux-edac list suggested I ask you to pull that change through my
tree since they don't have a tree to pull edac changes from at the
moment."
