Ugh, I'll dig through this later on today, we must be missing something
with those backports that Ben did...
69ce144e5c3a ("mm: replace get_user_pages() write/force parameters
with gup_flags") seems to have missed converting a call of
get_user_pages().
Right. This was changed earlier upstream in commit cde70140fed8
"mm/gup: Overload get_user_pages() functions", but I don't think it
makes sense to apply all of that. I'm attaching a minimal patch
(tested with an arm allnoconfig build) which should ideally be inserted
before mm-replace-get_user_pages-write-force-parameters-with-
gup_flags.patch.
Ben.

Thanks for the patch. I've added it to the queue and pushed out a -rc2
with this in it.
Let's see what the builders say :)
v4.4.167-89-g9c558d7fe359 seemed to be happy. v4.4.167-89-g50a0280f2f7e
replaced it and will take a while.
