Pull sched.h split-up from Ingo Molnar: "The point of these changes is to significantly reduce the <linux/sched.h> header footprint, to speed up the kernel build and to have a cleaner header structure. After these changes the new <linux/sched.h>'s typical preprocessed size goes down from a previous ~0.68 MB (~22K lines) to ~0.45 MB (~15K lines), which is around 40% faster to build on typical configs. Not much changed from the last version (-v2) posted three weeks ago: I eliminated quirks, backmerged fixes plus I rebased it to an upstream SHA1 from yesterday that includes most changes queued up in -next plus all sched.h changes that were pending from Andrew. I've re-tested the series both on x86 and on cross-arch defconfigs, and did a bisectability test at a number of random points. I tried to test as many build configurations as possible, but some build breakage is probably still left - but it should be mostly limited to architectures that have no cross-compiler binaries available on kernel.org, and non-default configurations" * 'WIP.sched-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (146 commits) sched/headers: Clean up <linux/sched.h> sched/headers: Remove #ifdefs from <linux/sched.h> sched/headers: Remove the <linux/topology.h> include from <linux/sched.h> sched/headers, hrtimer: Remove the <linux/wait.h> include from <linux/hrtimer.h> sched/headers, x86/apic: Remove the <linux/pm.h> header inclusion from <asm/apic.h> sched/headers, timers: Remove the <linux/sysctl.h> include from <linux/timer.h> sched/headers: Remove <linux/magic.h> from <linux/sched/task_stack.h> sched/headers: Remove <linux/sched.h> from <linux/sched/init.h> sched/core: Remove unused prefetch_stack() sched/headers: Remove <linux/rculist.h> from <linux/sched.h> sched/headers: Remove the 'init_pid_ns' prototype from <linux/sched.h> sched/headers: Remove <linux/signal.h> from <linux/sched.h> sched/headers: Remove <linux/rwsem.h> from <linux/sched.h> sched/headers: Remove the runqueue_is_locked() prototype sched/headers: Remove <linux/sched.h> from <linux/sched/hotplug.h> sched/headers: Remove <linux/sched.h> from <linux/sched/debug.h> sched/headers: Remove <linux/sched.h> from <linux/sched/nohz.h> sched/headers: Remove <linux/sched.h> from <linux/sched/stat.h> sched/headers: Remove the <linux/gfp.h> include from <linux/sched.h> sched/headers: Remove <linux/rtmutex.h> from <linux/sched.h> ...

Pull turbostat utility updates from Rafael Wysocki: "Power management turbostat utility updates. These update turbostat significantly and in particular: - default output is now verbose, --debug is no longer required to get all counters. As a result, some options have been added to specify exactly what output is wanted. - added --quiet to skip system configuration output - added --list, --show and --hide parameters - added --cpu parameter - enhanced Baytrail SoC support - added Gemini Lake SoC support - added sysfs C-state columns Also the symbol definitions in arch/x86/include/asm/intel-family.h and arch/x86/include/asm/msr-index.h are updated and the intel_idle and intel_pstate drivers are modified to use the updated symbols.

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() -

Now that <linux/sched.h> dependencies have been sorted out, do various trivial cleanups: - remove unnecessary structure predeclarations - fix various typos - update comments where necessary - remove pointless comments - use consistent types - tabulate consistently - use a consistent comment style - clean up the header section a bit - use a consistent style of a single field per line - remove line-breaks where they make the code look worse - etc ... No change in functionality. Acked-by:

It's used only by a single (rarely used) inline function (task_node(p)), which we can move to <linux/sched/topology.h>. ( Add <linux/nodemask.h>, because we rely on that. ) Acked-by:

In our quest to simplify <linux/sched.h>'s header dependencies, remove the <linux/wait.h> inclusion from <linux/hrtimer.h> - which does not appear to be necessary, as hrtimer.h does not use waitqueues. Acked-by:

We want to simplify <linux/sched.h>'s header dependencies, but one roadblock to that is <asm/apic.h>'s inclusion of pm.h, which brings in other, problematic headers. Remove it, as it appears to be entirely spurious, apic.h does not actually make use of any PM facilities. Acked-by:

So we want to simplify <linux/sched.h>'s header dependencies, but one roadblock of that is <linux/timer.h>'s inclusion of sysctl.h, which brings in other, problematic headers. Note that timer.h's inclusion of sysctl.h can be avoided if we pre-declare ctl_table - so do that. Acked-by:

Instead of including the full <linux/signal.h>, only include the types-only <linux/signal_types.h> header in <linux/sched.h>, to further decouple the scheduler header from the signal headers. Acked-by:

<linux/kasan.h> is a low level header that is included early in affected kernel headers. But it includes <linux/sched.h> which complicates the cleanup of sched.h dependencies. Remove it. Acked-by:
