Subject: IRQ: check for PERCPU flag only when adding first irqaction
From: "Ahmed S. Darwish" <darwish.07@xxxxxxxxx>
An irqaction structure won't be added to an IRQ descriptor irqaction list if
it doesn't agree with other irqactions on the IRQF_PERCPU flag. Don't check
for this flag to change IRQ descriptor `status' for every irqaction added to
the list, Doing the check only for the first irqaction added is enough.
