[PATCH] IRQ: Use SA_PERCPU_IRQ, not IRQ_PER_CPU, for irqaction.flags
- From: Bjorn Helgaas <bjorn.helgaas@xxxxxx>

IRQ_PER_CPU is a bit in the struct irq_desc "status" field, not
in the struct irqaction "flags", so the previous code checked the
wrong bit.
SA_PERCPU_IRQ is only used by drivers/char/mmtimer.c for SGI ia64 boxes.
