From 916d11b2b52430576fd4e96138c974cd64f9cfd6 Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Fri, 18 Sep 2009 12:12:46 +0200 Subject: [PATCH] amd64_edac: fix DRAM base and limit address extraction K8 DRAM base and limit addresses from F1x40 +8*i and F1x44 + 8*i, where i in (0..7) are both bits 39-24 and therefore the shifting should be done by 24 and not by 8.
