Thanks for implementing this, much appreciated. If you need people to
test stuff, lemme know.

My only concern is how we would catch the other extremity where the
inline asm grows too big and we end up inlining it everywhere and thus
getting fat. The 0day bot already builds tinyconfigs but we should be
looking at vmlinux size growth too.

Thx.
