David Hildenbrand 40f2bbf711 mm/rmap: drop "compound" parameter from page_add_new_anon_rmap()
New anonymous pages are always mapped natively: only THP/khugepaged code
maps a new compound anonymous page and passes "true".  Otherwise, we're
just dealing with simple, non-compound pages.

Let's give the interface clearer semantics and document these.  Remove the
PageTransCompound() sanity check from page_add_new_anon_rmap().
