Specifics:
- In this pull, I am including a series of fixes that was supposed to make 3.18, but I decided to send them for v3.19. I left for v3.19 because the required changes modified a couple of APIs. Therefore, the redesign had to be done properly. The major fix here is to have proper sequencing between cpufreq layer and cpu cooling registration. A take away of this fix is an improvement in the thermal drivers code. Thermal drivers that require cpu cooling do not need to check for cpufreq layer. The requirement now is to propagate the error code, if any, while registering cpu cooling device. Thanks to Viresh for implementing the required CPUfreq changes.
- While in the subject, Viresh took the opportunity to review the cpu cooling code from a cpufreq layer user perspective, which resulted in several cleanups.
- The content in this pull depends on CPUfreq refactoring done by Viresh, which is part of the pull sent by Rafael J. W.:
