Subject: [PATCH v1 0/4] cpuidle: governors: teo: Assorted improvements

Hi,

This is a bunch of teo cpuidle governor improvements, some of which are related
to a bug report discussed recently:

https://lore.kernel.org/linux-pm/CAEmPcwsNMNnNXuxgvHTQ93Mx-q3Oz9U57THQsU_qdcCx1m4w5g@mail.gmail.com/

The first patch fixes a bug that may cause an overly deep idle state
to be selected when the scheduler tick has been already stopped.

Patch [2/4] removes an unnecessary function argument.

Patch [3/4] makes teo_update() to use s64 as the data type for its local
variables more consistently.

The last patch reworks the governor's decay implementation to also decay
metric values lower than 8.

Thanks!
