From 17311c03c3e2c16d64d9e8cb2a3f45be2e2f8d3b Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Sat, 1 Jul 2006 04:35:44 -0700 Subject: [PATCH] IRQ: Use SA_PERCPU_IRQ, not IRQ_PER_CPU, for irqaction.flags 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.
