Pull thermal control updates from Rafael Wysocki:
 "These are thermal core changes, including the addition of support for
  temperature thresholds that can be set from user space, fixes related
  to thermal zone initialization, suspend/resume and exit, locking
  rework and rearrangement of the code handling thermal zone temperature
  updates.

  Specifics:

   - Add support for thermal thresholds that can be added and removed
     from user space via netlink along with a related library update
     (Daniel Lezcano)

   - Fix thermal zone initialization, suspend/resume and exit
     synchronization issues (Rafael Wysocki)

   - Rearrange locking in the thermal core to use guards (Rafael
     Wysocki)

   - Make the code handling thermal zone temperature updates use sorted
     lists of trip points to reduce the number of trip points table
     walks in the thermal core (Rafael Wysocki)

   - Fix and clean up the thermal testing facility code (Rafael Wysocki)

   - Fix a Power Allocator thermal governor issue (ZhengShaobo)"
