Pull power management updates from Rafael Wysocki:
"There are no real big ticket items here this time.
The most noticeable change is probably the relocation of the OPP
(Operating Performance Points) framework to its own directory under
drivers/ as it has grown big enough for that. Also Viresh is now going
to maintain it and send pull requests for it to me, so you will see
this change in the git history going forward (but still not right
now).
Another noticeable set of changes is the modifications of the PM core,
the PCI subsystem and the ACPI PM domain to allow of more integration
between system-wide suspend/resume and runtime PM. For now it's just a
way to avoid resuming devices from runtime suspend unnecessarily
during system suspend (if the driver sets a flag to indicate its
readiness for that) and in the works is an analogous mechanism to
allow devices to stay suspended after system resume.
In addition to that, we have some changes related to supporting
frequency-invariant CPU utilization metrics in the scheduler and in
the schedutil cpufreq governor on ARM and changes to add support for
device performance states to the generic power domains (genpd)
framework.
The rest is mostly fixes and cleanups of various sorts.
Specifics:
- Relocate the OPP (Operating Performance Points) framework to its
own directory under drivers/ and add support for power domain
performance states to it (Viresh Kumar).
- Modify the PM core, the PCI bus type and the ACPI PM domain to
support power management driver flags allowing device drivers to
specify their capabilities and preferences regarding the handling
of devices with enabled runtime PM during system suspend/resume and
clean up that code somewhat (Rafael Wysocki, Ulf Hansson).
- Add frequency-invariant accounting support to the task scheduler on
ARM and ARM64 (Dietmar Eggemann).
- Fix PM QoS device resume latency framework to prevent "no
restriction" requests from overriding requests with specific
requirements and drop the confusing PM_QOS_FLAG_REMOTE_WAKEUP
device PM QoS flag (Rafael Wysocki).
- Drop legacy class suspend/resume operations from the PM core and
drop legacy bus type suspend and resume callbacks from ARM/locomo
(Rafael Wysocki).
- Add min/max frequency support to devfreq and clean it up somewhat
(Chanwoo Choi).
- Rework wakeup support in the generic power domains (genpd)
framework and update some of its users accordingly (Geert
Uytterhoeven).
- Convert timers in the PM core to use timer_setup() (Kees Cook).
- Add support for exposing the SLP_S0 (Low Power S0 Idle) residency
counter based on the LPIT ACPI table on Intel platforms (Srinivas
Pandruvada).
- Add per-CPU PM QoS resume latency support to the ladder cpuidle
governor (Ramesh Thomas).
- Fix a deadlock between the wakeup notify handler and the notifier
removal in the ACPI core (Ville Syrjälä).
- Fix a cpufreq schedutil governor issue causing it to use stale
cached frequency values sometimes (Viresh Kumar).
- Fix an issue in the system suspend core support code causing wakeup
events detection to fail in some cases (Rajat Jain).
- Fix the generic power domains (genpd) framework to prevent the PM
core from using the direct-complete optimization with it as that is
guaranteed to fail (Ulf Hansson).
- Fix a minor issue in the cpuidle core and clean it up a bit (Gaurav
Jindal, Nicholas Piggin).
- Fix and clean up the intel_idle and ARM cpuidle drivers (Jason
Baron, Len Brown, Leo Yan).
- Fix a couple of minor issues in the OPP framework and clean it up
(Arvind Yadav, Fabio Estevam, Sudeep Holla, Tobias Jordan).
- Fix and clean up some cpufreq drivers and fix a minor issue in the
cpufreq statistics code (Arvind Yadav, Bhumika Goyal, Fabio
Estevam, Gautham Shenoy, Gustavo Silva, Marek Szyprowski, Masahiro
Yamada, Robert Jarzmik, Zumeng Chen).
- Fix minor issues in the system suspend and hibernation core, in
power management documentation and in the AVS (Adaptive Voltage
Scaling) framework (Helge Deller, Himanshu Jha, Joe Perches, Rafael
Wysocki).
- Fix some issues in the cpupower utility and document that Shuah

Pull x86 APIC updates from Thomas Gleixner:
"This update provides a major overhaul of the APIC initialization and
vector allocation code:
- Unification of the APIC and interrupt mode setup which was
scattered all over the place and was hard to follow. This also
distangles the timer setup from the APIC initialization which
brings a clear separation of functionality.
Great detective work from Dou Lyiang!
- Refactoring of the x86 vector allocation mechanism. The existing
code was based on nested loops and rather convoluted APIC callbacks
which had a horrible worst case behaviour and tried to serve all
different use cases in one go. This led to quite odd hacks when
supporting the new managed interupt facility for multiqueue devices
and made it more or less impossible to deal with the vector space
exhaustion which was a major roadblock for server hibernation.
Aside of that the code dealing with cpu hotplug and the system
vectors was disconnected from the actual vector management and
allocation code, which made it hard to follow and maintain.
Utilizing the new bitmap matrix allocator core mechanism, the new
allocator and management code consolidates the handling of system
vectors, legacy vectors, cpu hotplug mechanisms and the actual
allocation which needs to be aware of system and legacy vectors and
hotplug constraints into a single consistent entity.
This has one visible change: The support for multi CPU targets of
interrupts, which is only available on a certain subset of
CPUs/APIC variants has been removed in favour of single interrupt
targets. A proper analysis of the multi CPU target feature revealed
that there is no real advantage as the vast majority of interrupts
end up on the CPU with the lowest APIC id in the set of target CPUs
anyway. That change was agreed on by the relevant folks and allowed
to simplify the implementation significantly and to replace rather
fragile constructs like the vector cleanup IPI with straight
forward and solid code.
Furthermore this allowed to cleanly separate the allocation details
for legacy, normal and managed interrupts:
* Legacy interrupts are not longer wasting 16 vectors
unconditionally
* Managed interrupts have now a guaranteed vector reservation, but
the actual vector assignment happens when the interrupt is
requested. It's guaranteed not to fail.
* Normal interrupts no longer allocate vectors unconditionally
when the interrupt is set up (IO/APIC init or MSI(X) enable).
The mechanism has been switched to a best effort reservation
mode. The actual allocation happens when the interrupt is
requested. Contrary to managed interrupts the request can fail
due to vector space exhaustion, but drivers must handle a fail
of request_irq() anyway. When the interrupt is freed, the vector
is handed back as well.
This solves a long standing problem with large unconditional
vector allocations for a certain class of enterprise devices
which prevented server hibernation due to vector space
exhaustion when the unused allocated vectors had to be migrated
to CPU0 while unplugging all non boot CPUs.
The code has been equipped with trace points and detailed debugfs
information to aid analysis of the vector space"

Pull timer updates from Thomas Gleixner:
"Yet another big pile of changes:
- More year 2038 work from Arnd slowly reaching the point where we
need to think about the syscalls themself.
- A new timer function which allows to conditionally (re)arm a timer
only when it's either not running or the new expiry time is sooner
than the armed expiry time. This allows to use a single timer for
multiple timeout requirements w/o caring about the first expiry
time at the call site.
- A new NMI safe accessor to clock real time for the printk timestamp
work. Can be used by tracing, perf as well if required.
- A large number of timer setup conversions from Kees which got
collected here because either maintainers requested so or they
simply got ignored. As Kees pointed out already there are a few
trivial merge conflicts and some redundant commits which was
unavoidable due to the size of this conversion effort.
- Avoid a redundant iteration in the timer wheel softirq processing.
- Provide a mechanism to treat RTC implementations depending on their
hardware properties, i.e. don't inflict the write at the 0.5
seconds boundary which originates from the PC CMOS RTC to all RTCs.
No functional change as drivers need to be updated separately.
- The usual small updates to core code clocksource drivers. Nothing
really exciting"

Pull x86 platform updates from Ingo Molnar:
"The main changes in this cycle were:
- a refactoring of the early virt init code by merging 'struct
x86_hyper' into 'struct x86_platform' and 'struct x86_init', which
allows simplifications and also the addition of a new
->guest_late_init() callback. (Juergen Gross)
- timer_setup() conversion of the UV code (Kees Cook)"
* 'x86-platform-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
