I am confused by something in ppc_irq_dispatch_handler(). It looks to me that the interrupt is ack-ed before the handler is called. Maybe I am misunderstanding, but doesn't the ack only reset the interrupt controller? If so, the interrupting hardware could still be presenting a level-triggered interrupt. Wouldn't it make more sense to let the interrupt routine get service the hardware first, then reset the interrupt controller?
