[v2,0/2] page_owner: Refcount fixups

Message

A couple of fixups for the refcounting part.
From this series on, instead of counting the stacks, we count the outstanding
nr_base_pages each stack has, which gives a much better memory overview.

The other fixup is for the migration part.
A more detailed explanation can be found in the changelog of respective patches.
