From 88d538672ea26223bca08225bc49f4e65e71683d Mon Sep 17 00:00:00 2001 From: Ashok Raj Date: Thu, 4 Jun 2015 18:55:23 +0200 Subject: x86/mce: Add infrastructure to support Local MCE Initialize and prepare for handling LMCEs. Add a boot-time option to disable LMCEs. Signed-off-by: Ashok Raj [ Simplify stuff, align statements for better readability, reflow comments; kill unused lmce_clear(); save us an MSR write if LMCE is already enabled. ] Signed-off-by: Borislav Petkov Cc: Andrew Morton Cc: H.
