Hi Everyone,

This patch series makes the ACPI thermal driver register thermal zones
with the help of thermal_zone_device_register_with_trips(), so it
doesn't need to use the thermal zone callbacks related to trip points
any more (and they are dropped in the last patch).

Yay!

The approach presented here is quite radically different from the
previous attempts, as it doesn't really rearrange the driver's
internal data structures, but adds the trip table support on top of
them. For this purpose, it uses an additional field in struct thermal_trip
introduced in the first patch.

I have run it on my test-bed systems, but this is not too representative,
because they each have only one ACPI thermal zone with only one (critical)
trip point in it.

Rui created some ACPI fake tables I was able to run them in a KVM machine with fake thermal zones.

I can share the setup if you are interested in
