Fix build error with !CONFIG_MIGRATION
migrate_huge_page_move_mapping() is declared as "extern int ..." in include/linux/migrate.h for !CONFIG_MIGRATION, which causes the build error like below: mm/mprotect.o: In function `migrate_huge_page_move_mapping': mprotect.c:(.text+0x0): multiple definition of `migrate_huge_page_move_mapping' mm/shmem.o:shmem.c:(.text+0x0): first defined here mm/rmap.o: In function `migrate_huge_page_move_mapping': rmap.c:(.text+0x0): multiple definition of `migrate_huge_page_move_mapping' mm/shmem.o:shmem.c:(.text+0x0): first defined here Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Naoya Horiguchi <n-horiguchi@ah.jp.nec.com> Signed-off-by: Andi Kleen <ak@linux.intel.com>
