Merge branch 'stable' of git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile
Pull arch/tile fix from Chris Metcalf:
"This change allows newer Tilera boot tools to work correctly with
current (and stable) kernels by using the right filename to get the
initramfs from the Tilera hypervisor filesystem."
* 'stable' of git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile:
tile: expect new initramfs name from hypervisor file system
