Hmm. I think this made my build time explode.

I'm bisecting, but it looks like my allmodconfig builds went from ~31
min to ~39 min with this pull.

NOTE! I'm  not saying that the kernel slowed down. Just the *build*
(with the same kernel) slowed down.

It's odd, and maybe I did something wrong, so I'll have to
double-check the numbers, but I thought I'd mention it in case
somebody goes "Ahh, I did X to the include files, so now every
compiler invocation probably sees all of xyz and that will slow things
down enormously".
