Convert drm/via to use the new pin_user_pages_fast() call, which sets
FOLL_PIN. Setting FOLL_PIN is now required for code that requires
tracking of pinned pages, and therefore for any code that calls
put_user_page().

No one's touching the via driver anymore, so feel free to merge this
through whatever tree suits best (aka I'll drop this on the floor and
forget about it now).

OK, great. Yes, in fact, I'm hoping Andrew can just push the whole series
in through the mm tree, because that would allow it to be done in one 
shot, in 5.5

btw is there more? We should have a bunch more userptr stuff in various
drivers, so was really surprised that drm/via is the only thing in your
series.
