[lm-sensors] [PATCH] hwmon,

[Andreas Herrmann <herrmann.der.user@googlemail.com>]

From: Andreas Herrmann <andreas.herrmann3@amd.com>

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

I think this patch should go into .35.
Patch was built against Linus' git v2.6.35-rc3-3-g9a3cde2.
(Hope that there is no conflict with your recent fix for single core
CPUs.)


Thanks,

Andreas
