Umm.  it is a Very Good call.

I applied it and actually tried to compile-check it, on kFreeBSD.
Compile went successfully, and I was satisfied, until I figured
that my kFreeBSD test script only builds qemu-system.  So I went
back and enabled this, and actually found the issue and even
fixed it locally, by adding the #includes.  While doing this, I
wondered, why such a basic/common subsystem is not included in
there to start with, and so isn't used?  Maybe this is something
which shouldn't be done?

But I got distracted from all this due to other issues, and when
I come back I just pushed the whole thing without noticing the
added #includes aren't committed, and forgetting about my doubts.
That's what you get when doing stuff in a hurry.

Yes, that's what I think too.  Should I send a formal patch
submission, or is `git revert' easy enough?  Even with my
Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
if needed?
