mm: replace get_user_pages_unlocked() write/force parameters with gup_flags
commit c164154f66f0c9b02673f07aa4f044f1d9c70274 upstream.
This removes the 'write' and 'force' use from get_user_pages_unlocked()
and replaces them with 'gup_flags' to make the use of FOLL_FORCE
explicit in callers as use of this flag can result in surprising
behaviour (and hence bugs) within the mm subsystem.
