I have one request. CPU throttling is already a very well established
term in the x86 world, refering to thermal throttling when the CPU
overheats. This is implemented by ACPI and the CPU. It's always
a very bad thing that should be avoided at all costs.

You seem to use it for something else. Can you please use a different
term for that? Reusing the same word for something else is confusing.

Thanks,
