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()
2017-03-03sched/headers: Remove <linux/magic.h> from <linux/sched/task_stack.h>Ingo Molnar1-0/+1
It's not used by any of the scheduler methods, but <linux/sched/task_stack.h> needs it to pick up STACK_END_MAGIC.

2017-03-03sched/headers: Remove <linux/rwsem.h> from <linux/sched.h>Ingo Molnar1-0/+1
This is a stray header that is not needed by anything in sched.h, so remove it. Update files that relied on the stray inclusion. This reduces the size of the header dependency graph.

2017-03-03sched/headers: Move cputime functionality from <linux/sched.h> and ↵Ingo Molnar1-111/+0
<linux/cputime.h> into <linux/sched/cputime.h> Move cputime related functionality out of <linux/sched.h>, as most code that includes <linux/sched.h> does not use that functionality. Move data types that are not included in task_struct directly to the signal definitions, into <linux/sched/signal.h>. Also merge the (small) existing <linux/cputime.h> header into <linux/sched/cputime.h>.

2017-03-03sched/headers, RCU: Move rcu_copy_process() from <linux/sched/task.h> to ↵Ingo Molnar1-0/+15
kernel/fork.c Move rcu_copy_process() into kernel/fork.c, which is the only user of this inline function. This simplifies <linux/sched/task.h> to the level that <linux/sched.h> does not have to be included in it anymore - which change is done in a subsequent patch.

2017-03-03sched/headers: Move task_struct::signal and task_struct::sighand types and ↵Ingo Molnar1-0/+1
accessors into <linux/sched/signal.h> task_struct::signal and task_struct::sighand are pointers, which would normally make it straightforward to not define those types in sched.h. That is not so, because the types are accompanied by a myriad of APIs (macros and inline functions) that dereference them. Split the types and the APIs out of sched.h and move them into a new header, <linux/sched/signal.h>. With this change sched.h does not know about 'struct signal' and 'struct sighand' anymore, trying to put accessors into sched.h as a test fails the following way: ./include/linux/sched.h: In function ‘test_signal_types’: ./include/linux/sched.h:2461:18: error: dereferencing pointer to incomplete type ‘struct signal_struct’ ^ This reduces the size and complexity of sched.h significantly. Update all headers and .c code that relied on getting the signal handling functionality from <linux/sched.h> to include <linux/sched/signal.h>. The list of affected files in the preparatory patch was partly generated by grepping for the APIs, and partly by doing coverage build testing, both all[yes|mod|def|no]config builds on 64-bit and 32-bit x86, and an array of cross-architecture builds. Nevertheless some (trivial) build breakage is still expected related to rare Kconfig combinations and in-flight patches to various kernel code, but most of it should be handled by this patch.

2017-03-02sched/fair: Make select_idle_cpu() more aggressivePeter Zijlstra2-1/+6
Kitsunyan reported desktop latency issues on his Celeron 887 because of commit: 1b568f0aabf2 ("sched/core: Optimize SCHED_SMT") ... even though his CPU doesn't do SMT. The effect of running the SMT code on a !SMT part is basically a more aggressive select_idle_cpu(). Removing the avg condition fixed things for him. I also know FB likes this test gone, even though other workloads like having it. For now, take it out by default, until we get a better idea.

<linux/sched/user.h> We are going to split <linux/sched/user.h> out of <linux/sched.h>, which will have to be picked up from other headers and a couple of .c files. Create a trivial placeholder <linux/sched/user.h> file that just maps to <linux/sched.h> to make this patch obviously correct and bisectable. Include the new header in the files that are going to need it.

2017-03-02mm/vmacache, sched/headers: Introduce 'struct vmacache' and move it from ↵Ingo Molnar1-2/+2
<linux/sched.h> to <linux/mm_types> The <linux/sched.h> header includes various vmacache related defines, which are arguably misplaced. Move them to mm_types.h and minimize the sched.h impact by putting all task vmacache state into a new 'struct vmacache' structure. No change in functionality.
