From: Alan Cox <alan@xxxxxxxxxxxxxxx> PA-RISC doesn't use a real IRQ 0 and James says "To be honest, we don't care very much. Parisc interrupts are cascading and mostly software assigned (except our EIEM which we keep internal). We use a base offset at 16 or 64 (depending on GSC presence or not) so IRQs 0-15 aren't legal on parisc either (we frob some of the hard coded ISA interrupts on the WAX eisa bus). We use NO_IRQ as an IRQ assignment error return and that's about it (and that error shouldn't ever really occur)."
