The introduction of the cpu-map topology node in the cpus node implies that cpus node might have children that are not cpu nodes. The DT parsing code needs updating otherwise it would check for cpu nodes properties in nodes that are not required to contain them, resulting in warnings that have no bearing on bindings defined in the dts source file.
Great, so a new DT with cpu-map entries may not work with old kernels. Please check the behavior. This should go to stable kernels. Rob
