From 3f806e50981825fa56a7f1938f24c0680816be45 Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Fri, 3 Feb 2012 20:18:01 +0100 Subject: [PATCH] x86/mce/AMD: Fix UP build error 141168c36cde ("x86: Simplify code by removing a !SMP #ifdefs from 'struct cpuinfo_x86'") removed a bunch of CONFIG_SMP ifdefs around code touching struct cpuinfo_x86 members but also caused the following build error with Randy's randconfigs: mce_amd.c:(.cpuinit.text+0x4723): undefined reference to `cpu_llc_shared_map' Restore the #ifdef in threshold_create_bank() which creates symlinks on the non-BSP CPUs. There's a better patch series being worked on by Kevin Winchester which will solve this in a cleaner fashion, but that series is too ambitious for v3.3 merging - so we first queue up this trivial fix and then do the rest for v3.4.
