+          Back when each arch used to define their own cpu_online_map and
+          cpu_possible_map, some of them chose to initialize cpu_possible_map
+          with all 1s, and others with all 0s.  When they were centralised,
+          it was better to provide this option than to break all the archs
+          and have several arch maintainers persuing me down dark alleys.
