Ben Hutchings 294c7a9fb6 mips,s390,sh,sparc: gup: Work around the "COW can break either way" issue 
In Linux 4.14 and 4.19 these architectures still have their own
implementations of get_user_pages_fast().  These also need to force
the write flag on when taking the fast path.

Fixes: 407faed92b4a ("gup: document and work around "COW can break either way" issue")
