    Subject[PATCH 10/21] openrisc: use for_each_of_cpu_node iterator
    Date
    Use the for_each_of_cpu_node iterator to iterate over cpu nodes. This
    has the side effect of defaulting to iterating using "cpu" node names in
    preference to the deprecated (for FDT) device_type == "cpu".

    This also fixes a leaked reference for cpus node.
