git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \ pm-4.11-rc4 with top-most commit 90ff2b729e181fba628b854eac2097e5ccc22e66 Merge branch 'pm-cpuidle-fixes' on top of commit 97da3854c526d3a6ee05c849c96e48d21527606c Linux 4.11-rc3 to receive power management fixes for v4.11-rc4. One of these is an intel_pstate regression fix and it is not a small change, but it mostly removes code that shouldn't be there. That code was acquired by mistake and has been a source of constant pain since then, so the time has come to get rid of it finally. We have not seen problems with this change in the lab, so fingers crossed. The rest is more usual: one more intel_pstate commit removing useless code, a cpufreq core fix to make it restore policy limits on CPU online (which prevents the limits from being reset over system suspend/resume), a schedutil cpufreq governor initialization fix to make it actually work as advertised on all systems and an extra sanity check in the cpuidle core to prevent crashes from happening if the arch code messes things up. Specifics: - Make intel_pstate use one set of global P-state limits in the active mode regardless of the scaling_governor settings for individual CPUs instead of switching back and forth between two of them in a way that is hard to control (Rafael Wysocki). - Drop a useless function from intel_pstate to prevent it from modifying the maximum supported frequency value unexpectedly which may confuse the cpufreq core (Rafael Wysocki). - Fix the cpufreq core to restore policy limits on CPU online so that the limits are not reset over system suspend/resume, among other things (Viresh Kumar). - Fix the initialization of the schedutil cpufreq governor to make the IO-wait boosting mechanism in it actually work on systems with one CPU per cpufreq policy (Rafael Wysocki). - Add a sanity check to the cpuidle core to prevent crashes from happening if the architecture code initialization fails to set up things as expected (Vaidyanathan Srinivasan).
