The per cpu nmi watchdog timer is based on an event counter.
idle cpus don't generate events so the NMI watchdog doesn't fire
and the test to see if the watchdog is working fails.
Question: given all the concern about reducing clocks and all, do we
actually need nmi on more than one CPU? Are there cases where a single
CPU hangs in idle on an SMP system?
