Why is that beneficial especially in the context of a NMI watchdog which then broadcasts the NMI to all other CPUs? That's wishful thinking perhaps, but I don't see any benefit at all. > Prepend the functions matrix_find_best_cpu_managed() and > matrix_find_best_cpu_managed() The same function prepended twice becomes two functions :) > with the irq_ prefix and expose them for > IRQ controllers to use when allocating and activating vector-less IRQs. There is no such thing like a vectorless IRQ. NMIs have a vector. Can we please describe facts and not pulled out of thin air concepts which do not exist?
