I do agree that removing CONFIG_MEMORY_HOTREMOVE makes some sense. But
this patch being a mid step should be simpler rather than going half way
to get there. I would have liked the above for the purpose of this patch
more and then go with another one to remove the config altogether. But
Andrew has already sent his patch bomb including this series to Linus so
this is all moot.
