OK, so I started writing that patch... or rather, I wrote the patch and
started on the Changelog when I ran into trouble describing why we need
it.

That is, I'm struggling to explain why we cannot flip

Yes, it breaks ftrace, but I'm thinking that is all it breaks. So let me
see if we can cure that.
