There's only NMI_LOCAL and NMI_UNKNOWN, and you can only use NMI_LOCAL
if you can tell you generated the NMI. See it as one massively shared
interrupt line.

The NMI_UNKNOWN handler is basically the handler of last resort for
those that cannot multiplex the line, hence the restriction of only
having one.
