	Unless you are ready to write support for interrupt affinity, cleanup
	the APIC code to use logical topology and do the necessary cleanups to
	the PCI interrupt routing code, these things take time.

	But yes, support for interrupt affinity is in the list of things that
	need to be done.

	The amount of hands at DragonFly's kernel code are limited.
