okay. So I had a discussion with Boris and we agreed that we don't do the init part in one place only the timer stuff will be moved. If I understand Tony correctly then we undo something in vendor_disable_error_reporting() (on !INTEL CPUs) that we enable in identify_cpu(). Boris, if my understanding is correct, what now? Do move the whole hotplug init part to an earlier stage? Or do we drop vendor_disable_error_reporting()? > -Tony Sebastian
