From 3f4f09b4be35d38d6e2bf22c989443e65e70fc4c Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Fri, 9 Jul 2010 16:22:51 +0200 Subject: [PATCH] hwmon: (coretemp) Properly label the sensors Don't assume that CPU entry number and core ID always match. It worked in the simple cases (single CPU, no HT) but fails on multi-CPU systems.
