[PATCH 3/8] x86/mce: Fix order of AMD MCE init function call Borislav Petkov <bp@alien8.de> - 2016-01-25 20:50 +0100

| Subject | [PATCH 3/8] x86/mce: Fix order of AMD MCE init function call |
| Message-ID | <qUVjb-pt-1@gated-at.bofh.it> |
From: Aravind Gopalakrishnan <Aravind.Gopalakrishnan@amd.com>
In mce_amd_feature_init() we take decisions based on mce_flags being set
or not. So the feature detection using CPUID should naturally be ordered
before we call mce_amd_feature_init().
Fix that here.
