Thanks.

Right, that's what it looked like. In my case, I'm doing CI on some
homebrewed infra, where I'm building lots of kernels for lots of
architectures and testing them in qemu with various tests _for each
and every commit_. Not having a server farm as impressive as Intel's
0-day infra, getting compilation times down is rather important.

Shucks. It's not like this patch makes the situation worse; it makes
it better. But I understand and will wait for 4.20/5.0.
