    mm: CONFIG_MMU for PG_mlocked · af8e3354
    Hugh Dickins authored
    Remove three degrees of obfuscation, left over from when we had
    CONFIG_UNEVICTABLE_LRU.  MLOCK_PAGES is CONFIG_HAVE_MLOCKED_PAGE_BIT is
    CONFIG_HAVE_MLOCK is CONFIG_MMU.  rmap.o (and memory-failure.o) are only
    built when CONFIG_MMU, so don't need such conditions at all.
    
    Somehow, I feel no compulsion to remove the CONFIG_HAVE_MLOCK* lines from
    169 defconfigs: leave those to evolve in due course.
