Realistically, "logical" just means we make up a numbering scheme
independent of what the HW tells us. If the HW isn't telling us
anything, then us telling the HW is fine.
The gist of the "no more logical mappings edict" is that basically we
only have one source for CPU numbers (and it can be sparse) rather than
two, one of which was usually compact.
