From 48e30fa0738be3688f655632d917498464019e60 Mon Sep 17 00:00:00 2001 From: Dimitri Sivanich Date: Wed, 22 Feb 2012 11:11:06 -0800 Subject: [PATCH] [IA64] genirq fixup for SGI/SN This patch allows the system to boot and enables the console and at least some hardware drivers, as well as some platform error handling. Tested on a variety of SGI Altix system without issues.
