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()?
