From eee45269b0f5979c70bc151c6c2f4e5f4f5ababe Mon Sep 17 00:00:00 2001 From: Ivan Kokshaysky Date: Fri, 6 Jan 2006 00:12:21 -0800 Subject: [PATCH] Alpha: convert to generic irq framework (generic part) Thanks to Christoph for doing most of the work. This allows automatic SMP IRQ affinity assignment other than default "all interrupts on all CPUs" which is rather expensive. This might be useful if the hardware can be programmed to distribute interrupts among different CPUs, like Alpha does.
