What anomalies? Please describe the actual problem you're seeing, with details, and why you think this is the correct fix. This is a revert of 3af229f2071f ("powerpc/numa: Reset node_possible_map to only node_online_map"), so please explain why all the things mentioned in the change log for that commit are either wrong or no longer true. cheers
