From a005677b3dd05decdd8880cf3044ae709856f58f Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Tue, 8 Feb 2011 17:11:03 +0100 Subject: 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.
