How are dirty caches handled here for the dying CPU? Bear in mind at the
moment, all that is left to the smp platform implementation, but I don't
see anything in your patch set so far which handles this.
This is going to be especially important as we're moving that into the
generic CPU hotplug code out of the platform code.
