Users will want to set these moveable zones along node boundaries
(the whole purpose is to be able to remove a node by making sure
the kernel won't allocate anything tricky in it, right?) So raw addresses
are usable ... but to get them right the user will have to go parse the
SRAT table manually to come up with the addresses. Any time you
make the user go off and do some tedious calculation that the computer
should have done for them is user-abuse.
