I've just noticied that the x86 GUP conversion haven't made it's way to v4.12: the fix got applied (71389703839e), but the final commit that does convertion keeped reverted -- 6dd29b3df975.
I guess it's too late for v4.12...
Ingo could you re-apply 2947ba054a4d ("x86/mm/gup: Switch GUP to the generic get_user_page_fast() implementation") to be queued to v4.13?
