Subject: [PATCH 3/3] Fix compenstion using "Processor" thermal cooling device

When any of the processor state is changed, it will impact all
7
 
processors. If thermal sysfs defines different cdev trip for
8
 
each processor, if we read and apply, the next processor will
9
 
already impacted by change by previous cdev.
