So, would you be OK with this implementation if the class were named
"Motherboard", "set-of-CPU-sockets", or something like that?
(The change on the APIC ID generation logic is not something that
affects only individual CPUs or APICs, but the fw_cfg NUMA & CPU hotplug
code as well, that's why I don't think "contiguous_apic_ids" should be a
property of CPU or APIC objects).
