Actually, perhaps we should not strive to do that.

Because particularly if we expect that this will want to be
back-ported into at least 4.14, maybe the right thing to do is to make
_that_ as easy as possible, and make the whole series be based on 4.14
(so that back-porting is literally just "merge the branch").

If I start taking this piece-meal, it is just going to make the
back-porting messier.
