These files need to be changed simultaneously in order to prevent
breakage during bisection and the like. I think the best bet moving
forward is to pull this into its own branch, tag it and send Maxime a
pull-request to the immutable branch. It's the best way to minimise
merge conflicts during the v4.1 merge window.
