We should still export cpu distances though because the distance between
cpus on the same node may not be equal. e.g. consider a node with multiple
cpu sockets, each socket with a hyperthreaded (or dual core) cpu.

Once again however, it depends on the definition of distance. For nodes,
we've established it's the ACPI SLIT (relative distance to memory). For
cpus, should it be distance to memory? Distance to cache? Registers? Or
what?
