All right. So I did this and the strict fix got into Andrew's tree as
mm-fix-potential-anon_vma-locking-issue-in-mprotect.patch

Andrew: when you try applying this series, this patch (2/7) won't
apply due to the strict fix being already there. Please just skip it
(and replace patch 4/7 with the replacement I'm about to send, so that
we end up with the same end state)
