Another approach is like the following:
movable_node = 1,3-5,8
This could set all the memory on the nodes to be movable. And the rest
of memory works as usual. But movablecore_map is more flexible.
... but *much* harder for users, so movable_node is better in most cases.
But numa is initialized very later, and we need the information in SRAT...

I think you need to deal with it for usability reasons, though...
