[PATCH v3 0/3] page_owner: Fix refcount imbalance

[Oscar Salvador <osalvador@suse.de>]

This series consists of a refactoring/correctness of updating the metadata
of tail pages and 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 us a much better memory overview.
The other fixup is for the migration part.

A more detailed explanation can be found in the changelog of the respective
patches.
