I agree that we should be clearing the mapping at node hot-remove since any cpu that would subsequently get onlined and assume one of the previous cpu's ids is not guaranteed to have the same affinity. I'm just really hoping that we don't touch the acpi code and that we can remove both cpu_hotplug-unmap-cpu2node-when-the-cpu-is-hotremoved.patch and cpu_hotplug-unmap-cpu2node-when-the-cpu-is-hotremoved-fix.patch from -mm.
