mm/Kconfig: add MMU dependency for MIGRATION.
MIGRATION must depend on MMU, or allmodconfig for the nommu sh architecture fails to build: CC mm/migrate.o mm/migrate.c: In function 'remove_migration_pte': mm/migrate.c:134:3: error: implicit declaration of function 'pmd_trans_huge' [-Werror=implicit-function-declaration] if (pmd_trans_huge(*pmd)) ^ mm/migrate.c:149:2: error: implicit declaration of function 'is_swap_pte' [-Werror=implicit-function-declaration] if (!is_swap_pte(pte)) ^ ... Also let CMA depend on MMU, or when NOMMU, if we select CMA, it will select MIGRATION by force.
