This update uses a different approach to mutual exclusion between trip point
updates in the ACPI thermal driver and the thermal core (roughly speaking, it
adds a "thermal zone update" callback and a helper to invoke that callback
under the zone lock) and a different mechanism to get from the local trip
point representation in the driver to the corresponding trips[i] in the
thermal zone structure.

As a result, some have been dropped, some new patches have been added and
the majority of patches in the series have been reworked from scratch.

Thanks!
