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

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

From: Andreas Herrmann <andreas.herrmann3(a)amd.com>

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
