This revision of the series places any otherwise unmapped CPUs into a cluster in order to avoid confusing the scheduler if no topology information is provided. This means that we should never bring up a CPU with no topology information so while the warning is still present and has been upgraded it should never triger unless there is a genuine bug (as opposed to missing information).
