Subject: [005/165] hwmon: (coretemp) Properly label the sensors

2.6.32-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Jean Delvare <khali@...ux-fr.org>

commit 3f4f09b4be35d38d6e2bf22c989443e65e70fc4c upstream.

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.
