From fff2e89f11dd9b9b45e9212bc543154ca3d028a1 Mon Sep 17 00:00:00 2001 From: Jacob Shin Date: Mon, 26 Jun 2006 13:58:50 +0200 Subject: [PATCH] x86_64: mce_amd relocate sysfs files Get rid of /sys/devices/system/threshold directory and move mce_amd thresholding files into the machine sysfs directory -- /sys/devices/system/machinecheck.
