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?
