So in general, IPI as a normal IRQ is still useful for debugging but
it can't debug a core which is stuck in deadlock with interrupts
disabled.
And since we choose override default

Introduce framework to turn an IPI as NMI using pseudo NMIs. In case a
particular platform doesn't support pseudo NMIs, then request IPI as a
regular IRQ.
The main motivation for this feature is to have an IPI that can be
leveraged to invoke NMI functions

Introduce framework to turn an IPI as NMI using pseudo NMIs. In case a
particular platform doesn't support pseudo NMIs, then request IPI as a
regular IRQ.
The main motivation for this feature is to have an IPI that can be
leveraged to invoke NMI functions on other CPUs. And current prospective
