If the arch needs to change it, that's fine, I guess. What I'm saying is that we should move this table building and maintenance to numa code proper. It was already a bit icky to build it inside workqueue. Trying to manage it dynamically manage it from there is too ugly. Let's please make this mapping table a proper part of NUMA infrastructure with proper notification callbacks.
