The MSI portions of this patchset is similar to the MSI cleanup
I was working on. I'll drop my patchkit and instead comment on
the relevant patches in this kit.

I got a couple of minor compile errors on i386 (kernel/io_apic.c).
I fixed them up by hand and the resulting kernel booted and
worked with MSI in the limited testing I've done so far.
