Subject: [GIT PULL] arch/tile bug fixes for v3.4-rc2

Linus,

Please pull the following changes for 3.4-rc2 from:

  git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile.git stable

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.
