commit: 9804c9eaeacfe78651052c5ddff31099f60ef78c From: Thomas Gleixner <[email protected]> Date: Mon, 7 Feb 2011 19:28:01 +0100 Subject: [PATCH] [PARISC] fix per-cpu flag problem in the cpu affinity checkers
The CHECK_IRQ_PER_CPU is wrong, it should be checking irq_to_desc(irq)->status not just irq.
