Have to admit that I did not read the patch carefully, but why
io_interrupt_sources_lock is __cpu_simple_lock?  Why not to re-use
cpu_lock?  The locking itself does not seem to be correct either.

How much of the IRQ affinity code (in x86/intr.c) is actually MD?
It seems that a lot of that can be made MI (think of kern/subr_intr.c).

Also, please do not forget to add the BSD license text for the newly
created files.
