From 7d7dc116e56c8a1ba4beb36d06a77a48fe5f750b Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Wed, 20 Mar 2013 15:07:28 +0100 Subject: x86, cpu: Convert AMD Erratum 400 Convert AMD erratum 400 to the bug infrastructure. Then, retract all exports for modules since they're not needed now and make the AMD erratum checking machinery local to amd.c. Use forward declarations to avoid shuffling too much code around needlessly.
