Just a note that I'm currently bisecting into this merge for a
horrendous performance regression.

It makes my empty kernel build go from 22 seconds to 44 seconds, and
makes a full kernel build enormously slower too.

I haven't finished the bisection, but it's now inside *just* this
pull, so I can already tell that I'm going to revert something in
here, because this has been making my merge window miserable.

You've been warned,
