i'd suggest cpu_online_map, i also added a busy-loop to wait for the
backtrace_mask to go back to 0. That way we get a consistent dump all
across. (as the NMI will dump on this CPU too)
if the NMI isnt working on some CPU, the wait might be quite long ;-)
But it's not a big issue i think as the system is likely hosed already.
