If you look at arch/powerpc/kernel/irq.c from line 479:

virq = irq_find_mapping(host, hwirq);
if (virq != IRQ_NONE) {
pr_debug("irq: -> existing mapping on virq %d\n", virq);
host->ops->map(host, virq, hwirq, flags);
return virq;
}
What if you comment out the host->ops->map(...) call in there ? Does it
help ?No, there's no change in behaviour.
