Fix migration.c compilation on s390
31bit s390 doesn't have huge pages and failed with:
> mm/migrate.c: In function 'remove_migration_pte':
> mm/migrate.c:143:3: error: implicit declaration of function 'pte_mkhuge'
> mm/migrate.c:143:7: error: incompatible types when assigning to type 'pte_t' from type 'int'
Put that code into a ifdef.
