From 25d61578daae697c4a0eb817f42a868af9824f82 Mon Sep 17 00:00:00 2001 From: John Keller Date: Thu, 10 May 2007 22:42:44 -0700 Subject: [IA64] SN: validate smp_affinity mask on intr redirect On SN, only allow one bit to be set in the smp_affinty mask when redirecting an interrupt. Currently setting multiple bits is allowed, but only the first bit is used in determining the CPU to redirect to. This has caused confusion among some customers.
