This adds an NMI handler per CPUs. x86, s390 and ppc CPUS are supported.
The change to existing behaviour is that x86 only delivers NMI to
the current monitored CPU now, not to every CPU.
So this series means that the "nmi" command and handler does
* NMI on x86
* reset on PPC
The vector is called "reset" but it is an interrupt, and I do not see any
way to mask it.
* restart on S390
The vector is called "restart" but it is still an interrupt.
So? ARM has an interrupt called "NMI" but there's zero reason
you'd want to poke it from the monitor, any more than you'd
want to try to hand-send any other kind of interrupt.
That doesn't seem generic at all, and suggests this should
not be a common CPU method/callback.
Oh. Ok. Suggestions?
I dunno. What are you actually trying to achieve?
It's a kind of "emergency button" on real machines. On PCs it sends an
NMI and this results in some kind of crash dump if the OS is configured
appropriately. The command may be ill-named for historical reasons, but
the effect is not x86-specific.
