From 6ede31e03084ee084bcee073ef3d1136f68d0906 Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Thu, 17 Dec 2009 00:16:25 +0100 Subject: x86, msr: msrs_alloc/free for CONFIG_SMP=n Randy Dunlap reported the following build error: "When CONFIG_SMP=n, CONFIG_X86_MSR=m: ERROR: "msrs_free" [drivers/edac/amd64_edac_mod.ko] undefined! ERROR: "msrs_alloc" [drivers/edac/amd64_edac_mod.ko] undefined!" This is due to the fact that is conditioned on CONFIG_SMP and in the UP case we have only the stubs in the header. Fork off SMP functionality into a new file (msr-smp.c) and build msrs_{alloc,free} unconditionally. Reported-by: Randy Dunlap Cc: H.
