Upstream fixup fa3fa55de0d ("cpuidle: governors: menu: Avoid using invalid recent intervals data") doesn't address the problems we are observing. Revert seems to be bringing performance metrics back to pre-regression levels.

Any details would be much appreciated. How do the idle state usages differ with and without "cpuidle: menu: Avoid discarding useful information"? What do the idle states look like in your platform?

Sure, I can run tests. How do I get the numbers/stats that you are asking for?
