It's easy enough to revert 041284181226 ("of/irq: Allow matching of an interrupt-map local to an interrupt controller"), and it seems like that's what we need to do. I have it tentatively queued up. That commit was part of the new support for the Apple M1 PCIe interface, and I don't know what effect a revert will have on that support. Marc, Alyssa? Bjorn
