cpuidle: Add 'above' and 'below' idle state metrics

2018-12-12T22:22:18Z

Add two new metrics for CPU idle states, "above" and "below", to count the number of times the given state had been asked for (or entered from the kernel's perspective), but the observed idle duration turned out to be too short or too long for it (respectively). These metrics help to estimate the quality of the CPU idle governor in use. Signed-off-by: Rafael J. Wysocki

cpuidle: Add cpuidle.governor= command line parameter

2018-12-11T11:08:44Z

Add cpuidle.governor= command line parameter to allow the default cpuidle governor to be replaced. That is useful, for example, if someone running a tickful kernel wants to use the menu governor on it. Signed-off-by: Rafael J. Wysocki

Documentation: admin-guide: PM: Add cpuidle document

2018-12-03T09:03:36Z

Important information is missing from user/admin cpuidle documentation available today, so add a new user/admin document for cpuidle containing current and comprehensive information to admin-guide and drop the old .txt documents it is replacing.
