When a PC has an NMI button, it is (I presume) connected to all CPUs'
LINT1 pin, which is often configured as an NMI input. So the all-cpu
variant corresponds to real hardware, while the single-cpu variant doesn't.
wrt the app developer POV, the only use I'm aware of is that you can
configure Windows to dump core when the NMI button is pressed and thus
debug driver problems. It's likely more reliable when sent to all cpus.
