From 7d20d14da1bf24199add02cf4293871c277a4bda Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Fri, 7 Jan 2011 17:58:04 +0100 Subject: amd64_edac: Adjust channel counting to F15h The only difference is that F10h used to sport ganged DCTs and F15h doesn't so adjust the F10h routine and reuse it.
