[Lee Schermerhorn <Lee.Schermerhorn@hp.com>]

PATCH revert shmem_lock() prototypes to return int

Against: 26-rc5-mm3 with Kosaki Motohiro's splitlru unevictable lru
fixes.

Fix to putback_lru_page()/unevictable page handling rework v3 patch.

The subject patch reverted a prior change to shmem_lock() to return a
struct address_space pointer back to returning an int.  This patch
updates the prototypes in mm.h to match.
