[PATCH v1 0/5] cpuidle: teo: Rework the idle state selection logic

[Rafael J. Wysocki]

Hi All,

This series of patches addresses some theoretical shortcoming in the
TEO (Timer Events Oriented) cpuidle governor by reworking its idle
state selection logic to some extent.

Patches [1-2/5] are introductory cleanups and the substantial changes are
made in patches [3-4/5] (please refer to the changelogs of these two
patches for details).  The last patch only deals with documentation.

Even though this work is mostly based on theoretical considerations, it
shows a measurable reduction of the number of cases in which the shallowest
idle state is selected while it would be more beneficial to select a deeper
one or the deepest idle state is selected while it would be more beneficial to
select a shallower one, which should be a noticeable improvement.

Thanks!
