Backport needed to adjust for context, and because Xenial kernel is still using
page_cache_release() instead of put_page().

The CVE page also mentions 95d78c28b5a8 ("fix unbalanced page refcounting in
bio_map_user_iov") as required, but it has been picked up already as part of
upstream update to 4.4.93 stable release.
