From 6e9de18120988388cdae5097c09e774416d58745 Mon Sep 17 00:00:00 2001 From: John Keller Date: Wed, 22 Aug 2007 19:32:06 -0500 Subject: [IA64] SN: Add support for CPU disable Add additional support for CPU disable on SN platforms. Correctly setup the smp_affinity mask for I/O error IRQs. Restrict the use of the feature to Altix 4000 and 450 systems running with a CPU disable capable PROM, and do not allow disabling of CPU 0.
