Merge git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile
Pull arch/tile updates from Chris Metcalf: "The only substantive pieces in this batch are some more vDSO support, and removing the reference to &platform_bus in tile-srom.c. The rest are minor issues reported to me" * git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile: tile: add clock_gettime support to vDSO tile: switch to using seqlocks for the vDSO time code tile gxio: use better string copy primitive char: tile-srom: Add real platform bus parent Removed repeated word in comments tilegx: Enable ARCH_SUPPORTS_ATOMIC_RMW tile: Remove tile-specific _sinitdata and _einitdata tile: use ARRAY_SIZE
