From 0a9c3ee7692fa20670986bcf550950e88ab9b4cc Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Wed, 11 Jan 2006 22:46:54 +0100 Subject: [PATCH] x86_64: Use safe_smp_processor_id in MCE handler hard_smp_processor_id would return the local APIC id instead of the Linux processor id. On big systems they are often not identical. safe_smp_processor_id is just a wrapper around it that does the necessary conversions.
