In my patches, I'm not sure there is much to adapt to your work as most of
it is arch specific (although I wont say no to another pair of eyes looking
at them). From what I've seen of your patches, the point where we converge
is that need for some code to be able to tell the irqchip "I want that
particular interrupt line to be treated/setup as an NMI".

Indeed, there has to be a generic way for the irqchip to announce that it
supports configuring an interrupt as NMI... and a way to actually configuring
it.

There has to be nothing. The irqchip infrastructure might be able to
provide certain aspects of NMI support, perhaps for initialization, but
everything else is fundamentally different and the executional parts simply
cannot use any of the irq chip functions at all.

Thanks,
