Merge tag 'pm-4.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management updates from Rafael Wysocki: "This time (again) cpufreq gets the majority of changes which mostly are driver updates (including a major consolidation of intel_pstate), some schedutil governor modifications and core cleanups. There also are some changes in the system suspend area, mostly related to diagnostics and debug messages plus some renames of things related to suspend-to-idle. One major change here is that suspend-to-idle is now going to be preferred over S3 on systems where the ACPI tables indicate to do so and provide requsite support (the Low Power Idle S0 _DSM in particular). The system sleep documentation and the tools related to it are updated too. The rest is a few cpuidle changes (nothing major), devfreq updates, generic power domains (genpd) framework updates and a few assorted modifications elsewhere. Specifics: - Drop the P-state selection algorithm based on a PID controller from intel_pstate and make it use the same P-state selection method (based on the CPU load) for all types of systems in the active mode (Rafael Wysocki, Srinivas Pandruvada). - Rework the cpufreq core and governors to make it possible to take cross-CPU utilization updates into account and modify the schedutil governor to actually do so (Viresh Kumar). - Clean up the handling of transition latency information in the cpufreq core and untangle it from the information on which drivers cannot do dynamic frequency switching (Viresh Kumar). - Add support for new SoCs (MT2701/MT7623 and MT7622) to the mediatek cpufreq driver and update its DT bindings (Sean Wang). - Modify the cpufreq dt-platdev driver to autimatically create cpufreq devices for the new (v2) Operating Performance Points (OPP) DT bindings and update its whitelist of supported systems (Viresh Kumar, Shubhrajyoti Datta, Marc Gonzalez, Khiem Nguyen, Finley Xiao). - Add support for Ux500 to the cpufreq-dt driver and drop the obsolete dbx500 cpufreq driver (Linus Walleij, Arnd Bergmann). - Add new SoC (R8A7795) support to the cpufreq rcar driver (Khiem Nguyen). - Fix and clean up assorted issues in the cpufreq drivers and core (Arvind Yadav, Christophe Jaillet, Colin Ian King, Gustavo Silva, Julia Lawall, Leonard Crestez, Rob Herring, Sudeep Holla). - Update the IO-wait boost handling in the schedutil governor to make it less aggressive (Joel Fernandes). - Rework system suspend diagnostics to make it print fewer messages to the kernel log by default, add a sysfs knob to allow more suspend-related messages to be printed and add Low Power S0 Idle constraints checks to the ACPI suspend-to-idle code (Rafael Wysocki, Srinivas Pandruvada). - Prefer suspend-to-idle over S3 on ACPI-based systems with the ACPI_FADT_LOW_POWER_S0 flag set and the Low Power Idle S0 _DSM interface present in the ACPI tables (Rafael Wysocki). - Update documentation related to system sleep and rename a number of items in the code to make it cleare that they are related to suspend-to-idle (Rafael Wysocki). - Export a variable allowing device drivers to check the target system sleep state from the core system suspend code (Florian Fainelli). - Clean up the cpuidle subsystem to handle the polling state on x86 in a more straightforward way and to use %pOF instead of full_name (Rafael Wysocki, Rob Herring). - Update the devfreq framework to fix and clean up a few minor issues (Chanwoo Choi, Rob Herring). - Extend diagnostics in the generic power domains (genpd) framework and clean it up slightly (Thara Gopinath, Rob Herring). - Fix and clean up a couple of issues in the operating performance points (OPP) framework (Viresh Kumar, Waldemar Rymarkiewicz). - Add support for RV1108 to the rockchip-io Adaptive Voltage Scaling (AVS) driver (David Wu). - Fix the usage of notifiers in CPU power management on some platforms (Alex Shi). - Update the pm-graph system suspend/hibernation and boot profiling utility (Todd Brandt). - Make it possible to run the cpupower utility without CPU0 (Prarit Bhargava)" * tag 'pm-4.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (87 commits) cpuidle: Make drivers initialize polling state cpuidle: Move polling state initialization code to separate file cpuidle: Eliminate the CPUIDLE_DRIVER_STATE_START symbol cpufreq: imx6q: Fix imx6sx low frequency support cpufreq: speedstep-lib: make several arrays static, makes code smaller PM: docs: Delete the obsolete states.txt document PM: docs: Describe high-level PM strategies and sleep states PM / devfreq: Fix memory leak when fail to register device PM / devfreq: Add dependency on PM_OPP PM / devfreq: Move private devfreq_update_stats() into devfreq PM / devfreq: Convert to using %pOF instead of full_name PM / AVS: rockchip-io: add io selectors and supplies for RV1108 cpufreq: ti: Fix 'of_node_put' being called twice in error handling path cpufreq: dt-platdev: Drop few entries from whitelist cpufreq: dt-platdev: Automatically create cpufreq device with OPP v2 ARM: ux500: don't select CPUFREQ_DT cpuidle: Convert to using %pOF instead of full_name cpufreq: Convert to using %pOF instead of full_name PM / Domains: Convert to using %pOF instead of full_name cpufreq: Cap the default transition delay value to 10 ms ...

+creates an html representation of the initcall timeline. It graphs
+every module init call found, through both kernel and user modes. The
+timeline is split into two phases: kernel mode & user mode. kernel mode
+represents a single process run on a single cpu with serial init calls.
+Once user mode begins, the init process is called, and the init calls
+start working in parallel.
