mm: replace get_user_pages() write/force parameters with gup_flags
commit 768ae309a96103ed02eb1e111e838c87854d8b51 upstream.
This removes the 'write' and 'force' from get_user_pages() 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.

[bwh: Backported to 4.4:
- Drop changes in rapidio, vchiq, goldfish
- Keep the "write" variable in amdgpu_ttm_tt_pin_userptr() as it's still
needed
- Also update calls from various other places that now use
get_user_pages_remote() upstream, which were updated there by commit
9beae1ea8930 "mm: replace get_user_pages_remote() write/force ..."
- Also update calls from hfi1 and ipath
- Adjust context]
