Hi Peter,

Yes, I understand your objection. Your want throttling to be done for
the purpose of thermal management only. The primary purpose for
throttling should be thermal management (power savings may be
a side-effect)

What I meant in the above comment was that the implementation for
throttling could be solved using resource management framework,
cpuset/cgroup rather than biasing the load balancer to avoid work on
a particular core.

I am open to ideas for a clean and easy framework for core level
throttling.

Thanks,
Vaidy
