Thanks, we obviously don't do a lot of coverage of UP any more.
I'm not sure if we should just move the bool's to be bitfields and
make them all available unconditionally, because the #ifdef in code
annoys me.
I'll think about it. The x86 maintainers are all on vacation this
week, and I don't want to disturb them, so I'll fix it one way or
another.
