From d5ccde0a64c3dbe954a8a13a6ba9fb3b6d7c6225 Mon Sep 17 00:00:00 2001 From: Kyle McMartin Date: Thu, 14 Oct 2010 22:31:11 -0400 Subject: [PATCH] alpha: use set_irq_chip and push down __do_IRQ to the machine types Also kill superfluous IRQ_DISABLED initialization, since that's the default state of the irq_desc[i].status field.
