-Thermal management updates from Zhang Rui, aimed at -rc1 :

This time we only have a few changes as there are no soc thermal changes
from Eduardo. The only big change is the introduction of TMON, a tool to
help visualize, tune, and test the thermal subsystem. The rest is mostly
cleanups and fixes all over.

Specifics:

- introduce TMON, a tool base on thermal sysfs I/F. It can be used to
visualize, tune and test the thermal subsystem.

- fix a zone/cooling device binding problem, when both thermal zone bind
parameters and .bind() callback are available.

-Greg Kroah-Hartman : kernels 3.4.69, 3.10.19 and 3.11.18.
