To be clear: I certainly agree that node_to_cpu[4,5] should list the CPUs
that are present, even if the nodes are memory-less. But you tell me how
20762 has changed this behaviour.

If it was changed by one of Intel's slightly earlier changesets (which is
possible) I'm happy to see it changed back. The new node_to_cpu[] behaviour
you are observing is obviously stupid, and I assume unintended.
