From 1de6bf33bc4601d856c286ad5c7d515468e24bbb Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Fri, 3 Feb 2006 21:51:29 +0100 Subject: [PATCH] [PATCH] x86_64: Fix zero mcfg entry workaround on x86-64 I broke this earlier when moving the patch from i386 to x86-64. Need to return the virtual address here, not the physical address. This fixes some boot time crashes on x86-64.
