Merge tag 'pm-extra-4.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull more power management updates deom Rafael Wysocki: "These fix two bugs introduced by recent power management updates (in the cpuidle menu governor and intel_pstate) and a few other issues, clean up things and remove unused code. Specifics: - Fix for a cpuidle menu governor problem that started to take an unnecessary spinlock after one of the recent updates and that did not play well with the RT patch (Rafael Wysocki). - Fix for the new intel_pstate operation mode switching feature added recently that did not reinitialize P-state limits properly when switching operation modes (Rafael Wysocki). - Removal of unused global notifiers from the PM QoS framework (Viresh Kumar). - Generic power domains framework update to make it handle asynchronous invocations of PM callbacks in the "noirq" phases of system suspend/hibernation correctly (Ulf Hansson). - Two hibernation core cleanups (Rafael Wysocki). - intel_idle cleanup related to the sysfs interface (Len Brown). - Off-by-one bug fix in the OPP (Operating Performance Points) framework (Andrzej Hajda). - OPP framework's documentation fix (Viresh Kumar). - cpufreq qoriq driver cleanup (Tang Yuantian). - Fixes for typos in comments in the device runtime PM framework (Christophe Jaillet)" * tag 'pm-extra-4.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: PM / OPP: Documentation: Fix opp-microvolt in examples intel_idle: stop exposing platform acronyms in sysfs cpufreq: intel_pstate: Fix limits issue with operation mode switching PM / hibernate: Define pr_fmt() and use pr_*() instead of printk() PM / hibernate: Untangle power_down() cpuidle: menu: Avoid taking spinlock for accessing QoS values PM / QoS: Remove global notifiers PM / runtime: Fix some typos cpufreq: qoriq: clean up unused code PM / OPP: fix off-by-one bug in dev_pm_opp_get_max_volt_latency loop PM / Domains: Power off masters immediately in the power off sequence PM / Domains: Rename is_async to one_dev_on for genpd_power_off() PM / Domains: Move genpd_power_off() above genpd_power_on()
