From 9530d608ef0e1f76b7fd82bb92645062292fc009 Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Mon, 6 Sep 2010 15:05:45 +0200 Subject: [PATCH] EDAC, MCE: Enable MCE decoding on F14h Now that all decoders have been taught about F14h, models < 0x10 MCEs, enable decoding on this family of CPUs. Also, issue a short informational message upon boot that MCE decoding gets enabled.
