    The patch description includes:

    5. Make it possible to configure NUMA systems without page migration
    and non-NUMA systems with page migration.


    I don't see the point in making this option visible for the majority of
    users on non-NUMA systems who will never need it.

    When is it required on non-NUMA systems?
    Memory hotplug?
    Can we express this explicitely?
