Pull staging and IIO updates from Greg KH: "Here is the "big" staging and IIO driver update for 4.15-rc1. Lots and lots of little changes, almost all minor code cleanups as the Outreachy application process happened during this development cycle. Also happened was a lot of IIO driver activity, and the typec USB code moving out of staging to drivers/usb (same commits are in the USB tree on a persistent branch to not cause merge issues.) Overall, it's a wash, I think we added a few hundred more lines than removed, but really only a few thousand were modified at all. All of these have been in linux-next for a while. There might be a merge issue with Al's vfs tree in the pi433 driver (take his changes, they are always better), and the media tree with some of the odd atomisp cleanups (take the media tree's version)" * tag 'staging-4.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (507 commits) staging: lustre: add SPDX identifiers to all lustre files staging: greybus: Remove redundant license text staging: greybus: add SPDX identifiers to all greybus driver files staging: ccree: simplify ioread/iowrite staging: ccree: simplify registers access staging: ccree: simplify error handling logic staging: ccree: remove dead code staging: ccree: handle limiting of DMA masks staging: ccree: copy IV to DMAable memory staging: fbtft: remove redundant initialization of buf staging: sm750fb: Fix parameter mistake in poke32 staging: wilc1000: Fix bssid buffer offset in Txq staging: fbtft: fb_ssd1331: fix mirrored display staging: android: Fix checkpatch.pl error staging: greybus: loopback: convert loopback to use generic async operations staging: greybus: operation: add private data with get/set accessors staging: greybus: loopback: Fix iteration count on async path staging: greybus: loopback: Hold per-connection mutex across operations staging: greybus/loopback: use ktime_get() for time intervals staging: fsl-dpaa2/eth: Extra headroom in RX buffers ...

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 Khan is going to maintain it going forward (Prarit Bhargava, Shuah Khan)" * tag 'pm-4.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (88 commits) tools/power/cpupower: add libcpupower.so.0.0.1 to .gitignore tools/power/cpupower: Add 64 bit library detection intel_idle: Graceful probe failure when MWAIT is disabled cpufreq: schedutil: Reset cached_raw_freq when not in sync with next_freq freezer: Fix typo in freezable_schedule_timeout() comment PM / s2idle: Clear the events_check_enabled flag cpufreq: stats: Handle the case when trans_table goes beyond PAGE_SIZE cpufreq: arm_big_little: make cpufreq_arm_bL_ops structures const cpufreq: arm_big_little: make function arguments and structure pointer const cpuidle: Avoid assignment in if () argument cpuidle: Clean up cpuidle_enable_device() error handling a bit ACPI / PM: Fix acpi_pm_notifier_lock vs flush_workqueue() deadlock PM / Domains: Fix genpd to deal with drivers returning 1 from ->prepare() cpuidle: ladder: Add per CPU PM QoS resume latency support PM / QoS: Fix device resume latency framework PM / domains: Rework governor code to be more consistent PM / Domains: Remove gpd_dev_ops.active_wakeup() callback soc: rockchip: power-domain: Use GENPD_FLAG_ACTIVE_WAKEUP soc: mediatek: Use GENPD_FLAG_ACTIVE_WAKEUP ARM: shmobile: pm-rmobile: Use GENPD_FLAG_ACTIVE_WAKEUP ...

Even though aperfmperf_snapshot_khz() caches the samples.khz value to return if called again in a sufficiently short time, its caller, arch_freq_get_on_cpu(), still uses smp_call_function_single() to run it which may allow user space to trigger an IPI storm by reading from the scaling_cur_freq cpufreq sysfs file in a tight loop. To avoid that, move the decision on whether or not to return the cached samples.khz value to arch_freq_get_on_cpu(). This change was part of commit 941f5f0f ("x86: CPU: Fix up "cpu MHz" in /proc/cpuinfo"), but it was not the reason for the revert and it remains applicable.

Pull x86 timer updates from Thomas Gleixner: "These updates are related to TSC handling: - Support platforms which have synchronized TSCs but the boot CPU has a non zero TSC_ADJUST value, which is considered a firmware bug on normal systems. This applies to HPE/SGI UV platforms where the platform firmware uses TSC_ADJUST to ensure TSC synchronization across a huge number of sockets, but due to power on timings the boot CPU cannot be guaranteed to have a zero TSC_ADJUST register value. - Fix the ordering of udelay calibration and kvmclock_init() - Cleanup the udelay and calibration code" * 'x86-timers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/tsc: Mark cyc2ns_init() and detect_art() __init x86/platform/UV: Mark tsc_check_sync as an init function x86/tsc: Make CONFIG_X86_TSC=n build work again x86/platform/UV: Add check of TSC state set by UV BIOS x86/tsc: Provide a means to disable TSC ART x86/tsc: Drastically reduce the number of firmware bug warnings x86/tsc: Skip TSC test and error messages if already unstable x86/tsc: Add option that TSC on Socket 0 being non-zero is valid x86/timers: Move simple_udelay_calibration() past kvmclock_init() x86/timers: Make recalibrate_cpu_khz() void x86/timers: Move the simple udelay calibration to tsc.h

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" * 'x86-apic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (60 commits) x86/vector/msi: Select CONFIG_GENERIC_IRQ_RESERVATION_MODE PCI/MSI: Set MSI_FLAG_MUST_REACTIVATE in core code genirq: Add config option for reservation mode x86/vector: Use correct per cpu variable in free_moved_vector() x86/apic/vector: Ignore set_affinity call for inactive interrupts x86/apic: Fix spelling mistake: "symmectic" -> "symmetric" x86/apic: Use dead_cpu instead of current CPU when cleaning up ACPI/init: Invoke early ACPI initialization earlier x86/vector: Respect affinity mask in irq descriptor x86/irq: Simplify hotplug vector accounting x86/vector: Switch IOAPIC to global reservation mode x86/vector/msi: Switch to global reservation mode x86/vector: Handle managed interrupts proper x86/io_apic: Reevaluate vector configuration on activate() iommu/amd: Reevaluate vector configuration on activate() iommu/vt-d: Reevaluate vector configuration on activate() x86/apic/msi: Force reactivation of interrupts at startup time x86/vector: Untangle internal state from irq_cfg x86/vector: Compile SMP only code conditionally x86/apic: Remove unused callbacks ...

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.

As reported by kernelci and other build bots, we now get a link failure without CONFIG_KALLSYMS: module.c:(.text+0xf2c): undefined reference to `kallsyms_show_value' This adds a dummy helper with the same name that can be used for compilation. It's not entirely clear to me what this should return for !CONFIG_KALLSYMS, I picked an unconditional 'false', which leads to the module address being unavailable to user space.

Pull documentation updates from Jonathan Corbet: "A relatively calm cycle for the docs tree again. - The old driver statement has been added to the kernel docs. - We have a couple of new helper scripts. find-unused-docs.sh from Sayli Karnic will point out kerneldoc comments that are not actually used in the documentation. Jani Nikula's documentation-file-ref-check finds references to non-existing files. - A new ftrace document from Steve Rostedt. - Vinod Koul converted the dmaengine docs to RST Beyond that, it's mostly simple fixes. This set reaches outside of Documentation/ a bit more than most. In all cases, the changes are to comment docs, mostly from Randy, in places where there didn't seem to be anybody better to take them" * tag 'docs-4.15' of git://git.lwn.net/linux: (52 commits) documentation: fb: update list of available compiled-in fonts MAINTAINERS: update DMAengine documentation location dmaengine: doc: ReSTize pxa_dma doc dmaengine: doc: ReSTize dmatest doc dmaengine: doc: ReSTize client API doc dmaengine: doc: ReSTize provider doc dmaengine: doc: Add ReST style dmaengine document ftrace/docs: Add documentation on how to use ftrace from within the kernel bug-hunting.rst: Fix an example and a typo in a Sphinx tag scripts: Add a script to find unused documentation samples: Convert timers to use timer_setup() documentation: kernel-api: add more info on bitmap functions Documentation: fix selftests related file refs Documentation: fix ref to power basic-pm-debugging Documentation: fix ref to trace stm content Documentation: fix ref to coccinelle content Documentation: fix ref to workqueue content Documentation: fix ref to sphinx/kerneldoc.py Documentation: fix locking rt-mutex doc refs docs: dev-tools: correct Coccinelle version number ...

The jprobes APIs are deprecated - but are still in occasional use for code that few people seem to care about, so stop generating deprecation warnings.
