BorisO reports that misc_register() fails often on xen. The current code unregisters the CPU hotplug notifier in that case. If then a CPU is offlined and onlined back again, we end up with a second timer running on that CPU, leading to soft lockups and system hangs. So let's leave the hotcpu notifier always registered - even if mce_device_create failed for some cores and never unreg it so that we can deal with the timer handling accordingly.
