    Most architectures (like i386) do nothing in flush_dcache_page, or don't scan
    i_mmap in flush_dcache_page, so don't need flush_dcache_mmap_lock to do
    anything: define it and flush_dcache_mmap_unlock away.  Noticed arm26, cris,
    h8300 still defining flush_page_to_ram: delete it again.
