On powerpc we have a mapping from virtual irq numbers (in the range 0 to NR_IRQS-1) to physical irq numbers (which can be anything) and back again. I think our approach is simpler than what's being proposed here, though we don't try to keep the irqdescs node-local as this patch seems to (fortunately our big systems aren't so NUMA-ish as to make that necessary).
