From 72f158fe6fc2033ceb0f3e0e9e5c2aa356fed6da Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Fri, 18 Sep 2009 12:27:27 +0200 Subject: amd64_edac: fix interleave enable tests The pvt->dram_IntlvEn saves the 3 "Interleave Enable" bits already right-shifted by 8 so the check in find_mc_by_sys_addr() by shifting the values to the left 8 bits is wrong.
