Besides, look at page_dup_rmap for copy_page_range: I don't
want to clutter that with inc_page_state(nr_reverse_maps).

It was mostly to determine space savings and internal fragmentation
on the pte_chain objects. It also helps get some notion of internal
fragmentation on pagetables. It's of low importance; delete at will.
