One suggestion: that we rename the syctl.physinfo field 'max_phys_cpus' to
'max_possible_cpus'. The 'phys' is kind of redundant since this is the
physinfo sysctl, and 'possible' provides a better hint that this fields
indicates maximum possible supported CPUs now and forever on this boot of
the system.
