Subject: [PATCH v11 11/14] mm/gup: change index type to long as it counts pages
In __get_user_pages_locked() i counts number of pages which should be
long, as long is used in all other places to contain number of pages, and
32-bit becomes increasingly small for handling page count proportional
values.
