Idle injection and soft IRQs:
We still have no good solution to avoid races with soft IRQ scheduling
while using idle injection. The previous post to kernel to solve this
issue is rejected. Peter proposed a change, that also didn't work.

I am proposing a discussion on how the solve this:
- May be we need to use some in kernel IRQ affinity change for the
forced idle CPUs
- Other potential solution?

Thermal sysfs/API Update

Thermal sysfs v2
There was proposal to correctly abstract thermal zones, sensors,
cooling devices and policies. Are we happy with the current state?

- Add capability to define additional private attributes for a zone
like cpufreq

Thanks,
