[017/205] hwmon: (k8temp) Fix temperature reporting for ASB1 processor revisions
From: Greg KH
Date: Fri Jul 30 2010 - 14:40:20 EST
2.6.34-stable review patch. If anyone has any objections, please let us know.
------------------
From: Andreas Herrmann <andreas.herrmann3@xxxxxxx>
commit d535bad90dad4eb42ec6528043fcfb53627d4f89 upstream.
Reported temperature for ASB1 CPUs is too high.
Add ASB1 CPU revisions (these are also non-desktop variants) to the
list of CPUs for which the temperature fixup is not required.
Example: (from LENOVO ThinkPad Edge 13, 01972NG, system was idle)
Current kernel reports
$ sensors
k8temp-pci-00c3
Adapter: PCI adapter
Core0 Temp: +74.0 C
Core0 Temp: +70.0 C
Core1 Temp: +69.0 C
Core1 Temp: +70.0 C
With this patch I have
$ sensors
k8temp-pci-00c3
Adapter: PCI adapter
Core0 Temp: +54.0 C
Core0 Temp: +51.0 C
Core1 Temp: +48.0 C
Core1 Temp: +49.0 C
