For pages that have a page_type, set the mapcount to 0, which will
reduce the confusion in people reading page dumps ("Why does this page
have a mapcount of -128?"). Now that hugetlbfs is a page_type, read the
entire_mapcount for any large folio; this is fine for all folios as no
user reuses the entire_mapcount field.
For pages which do not have a page type, do not print it to reduce
clutter.
