Subject: request_irq() and setup_irq()

Hi,
looking through the sources of 2.4.21 there come up one question. If a
device wants to register its interrupt it may call request_irq() that
then calls setup_irq(). Now since SA_PERCPU_IRQ is not set by the device
setup_irq() does not initialize desc->handler. Can that be fixed by
adding SA_PERCPU_IRQ to irqflags in request_irq() or does that introduce
problems at another place?
Christian
