Hi all,

The patch set a new callback for thermal governors and implementation for
Intelligent Power Allocator.

The goal is to move some heavy operarions like the memory allocations and heavy
computations (multiplications) out of throttle() callback hot path.

The new callback is generic enough to handle other imporants update events.
It re-uses existing thermal_notify_event definitions.

In addition there are some small clean-ups for IPA code.

changes:
v2:
- change callback name to update_tz() and add parameter (Rafael)
- added new event to trigger this callback - instance 'weight' update

Regards,
Lukasz
