[PATCH 8/8] EDAC, MCE: Enable MCE decoding on F14h

From: Borislav Petkov
Date: Tue Oct 05 2010 - 06:53:00 EST


From: Borislav Petkov <borislav.petkov@xxxxxxx>

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.
