genirq: Mirror IRQ_PER_CPU and IRQ_NO_BALANCING in irq_data.state
That's the right data structure to look at for arch code. Accessor functions are provided. irqd_is_per_cpu(irqdata); irqd_can_balance(irqdata); Coders who access them directly will be tracked down and slapped with stinking trouts. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
