I encountered the same issue that Micheal mentions in the other thread.
This is how the messages show up in a 40-cpu system with:

nr_cpus=2 (correct)
-------------------
CPU topo: Allowing 2 present CPUs plus 0 hotplug CPUs
CPU topo: Rejected CPUs 38

nr_cpus=1 (incorrect)
---------------------
CPU topo: Allowing 1 present CPUs plus 0 hotplug CPUs
CPU topo: Rejected CPUs 40
