[Processor] Hi-Temperature showed in trip points

[Processor] Hi-Temperature showed in trip points

[Renato S. Yamane]

Hi,
I have a laptop Toshiba M45-S355 (with Intel Pentium M Processor 750 - 
1.86GHz) and trip points show me hi-temperature (that is unsupported by 
this processor):

$ uname -a
Linux mandachuva 2.6.21.1 #1 PREEMPT Sun May 20 22:28:53 BRT 2007 i686 
GNU/Linux

$ cat /proc/acpi/thermal_zone/TZCL/trip_points
critical (S5):           105 C

MAX temperature suported by this processor is 100°C (I see this in Intel 
specifications), so I think that is not very good idea allow 
temperatures higher than 100°C.

$ cat /proc/acpi/processor/CPU0/info
processor id:            0
acpi id:                 0
bus mastering control:   yes
power management:        yes
throttling control:      yes
limit interface:         yes

Best regards,
Renato S. Yamane

That trip point comes from the BIOS.. likely complain to Toshiba, if 
anyone. Likely the CPU itself will start throttling or shut down well 
before that temperature is reached.

echo right values into trip points to lower this.

Note: Len removed that functionality in 2.6.22.
