alpha:
drivers/pcmcia/pcmcia_resource.c: In function 'pcmcia_request_irq':
drivers/pcmcia/pcmcia_resource.c:816: error: 'IRQ_NOAUTOEN' undeclared (first use in this function)
drivers/pcmcia/pcmcia_resource.c:816: error: (Each undeclared identifier is reported only once
drivers/pcmcia/pcmcia_resource.c:816: error: for each function it appears in.)
Problem is, IRQ_NOAUTOEN is a generic-irq thing, so architectures which
don't use generic-irqs break. And it's defined in linux/irq.h which
(stupidly) cannot be included in generic code.
