I think that adding a memory slot is a good first step.  Later if it 
shows up in profiles we can replace it with something else, but right 
now let's keep things simple.

It should probably be an internal memory slot, so we don't need to 
change userspace to use this feature, and we can react to changes in the 
apic base address.

(An internal memory slot would also be useful for storing the real-mode 
tss on Intel)

Question:  how does this interact with SMP?  Does each vcpu require its 
own page?
