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?
