The ACPI SCI (System Control Interrupt) is set up as a wakeup IRQ during suspend-to-idle transitions and, consequently, any events signaled through it wake up the system from that state. However, on some systems some of the events signaled via the ACPI SCI while suspended to idle should not cause the system to wake up. In fact, quite often they should just be discarded. Arguably, systems should not resume entirely on such events, but in order to decide which events really should cause the system to resume and which are spurious, it is necessary to resume up to the point when ACPI SCIs are actually handled and processed, which is after executing dpm_resume_noirq() in the system resume path. For this reasons, add a loop around freeze_enter() in which the platforms can process events signaled via multiplexed IRQ lines like the ACPI SCI and add suspend-to-idle hooks that can be used for this purpose to struct platform_freeze_ops. In the ACPI case, the ->wake hook is used for checking if the SCI has triggered while suspended and deferring the interrupt-induced system wakeup until the events signaled through it are actually processed sufficiently to decide whether or not the system should resume. In turn, the ->sync hook allows all of the relevant event queues to be flushed so as to prevent events from being missed due to race conditions. In addition to that, some ACPI code processing wakeup events needs to be modified to use the "hard" version of wakeup triggers, so that it will cause a system resume to happen on device-induced wakeup events even if the "soft" mechanism to prevent the system from suspending is not enabled (that also helps to catch device-induced wakeup events occurring during suspend transitions in progress).

The system wakeup framework is not very consistent with respect to the way it handles suspend-to-idle and generally wakeup events occurring during transitions to system low-power states. First off, system transitions in progress are aborted by the event reporting helpers like pm_wakeup_event() only if the wakeup_count sysfs attribute is in use (as documented), but there are cases in which system-wide transitions should be aborted even if that is not the case. For example, a wakeup signal from a designated wakeup device during system-wide PM transition, it should cause the transition to be aborted right away. Moreover, there is a freeze_wake() call in wakeup_source_activate(), but that really is only effective after suspend_freeze_state has been set to FREEZE_STATE_ENTER by freeze_enter(). However, it is very unlikely that wakeup_source_activate() will ever be called at that time, as it could only be triggered by a IRQF_NO_SUSPEND interrupt handler, so wakeups from suspend-to-idle don't really occur in wakeup_source_activate(). At the same time there is a way to abort a system suspend in progress (or wake up the system from suspend-to-idle), which is by calling pm_system_wakeup(), but in turn that doesn't cause any wakeup source objects to be activated, so it will not be covered by wakeup source statistics and will not prevent the system from suspending again immediately (in case autosleep is used, for example). Consequently, if anyone wants to abort system transitions in progress and allow the wakeup_count mechanism to work, they need to use both pm_system_wakeup() and pm_wakeup_event(), say, at the same time which is awkward. For the above reasons, make it possible to trigger pm_system_wakeup() from within wakeup_source_activate() and provide a new pm_wakeup_hard_event() helper to do so within the wakeup framework.

Pull ACPI updates from Rafael Wysocki: "These are some device enumeration code changes, updates of the AC and battery drivers to help them avoid attaching to devices that cannot be handled by them, new operation region driver for the Intel CHT Whiskey Cove PMIC, new sysfs entries for CPPC performance capabilities, a new _REV quirk blacklist entry and a couple of assorted minor fixes and cleanups. Specifics: - Update the core device enumeration code to make it more internally consistent and robust and drop the force_remove sysfs attribute that could be used to tell it to ignore errors on device hot-removal which was dangerous in general and no real and still relevant use cases for it could be found (Rafael Wysocki, Michal Hocko). - Make the core device enumeration code use _PXM to associate platform devices created by it with specific NUMA nodes (Shanker Donthineni). - Extend the CPPC library by adding more sysfs entries for performance capabilities to it and making it use the lowest nonlinear performance parameter (Prashanth Prakash). - Make the CPU online more consistent with CPU initialization in the ACPI processor driver (Prashanth Prakash). - Update the AC and battery drivers to help them avoid attaching to devices that cannot be handled by them and update the axp288_charger power supply driver to work correctly on ACPI systems without the INT3496 device (Hans de Goede). - Add an ACPI operation region driver for the Intel CHT Whiskey Cove PMIC and update the xpower operation region driver to work without IIO which isn't really necessary for it to work (Hans de Goede). - Add a new entry for Dell Inspiron 7537 to the _REV quirk blacklist (Kai Heng Feng). - Make the code in the ACPI video driver easier to follow by adding symbols and comments to it (Dmitry Frank). - Update ACPI documentation and drop a function that has no users from the tables-handling code (Cao jin, Baoquan He)" * tag 'acpi-4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / PMIC: Stop xpower OPRegion handler relying on IIO ACPI / PMIC: Add opregion driver for Intel CHT Whiskey Cove PMIC ACPI / scan: Avoid enumerating devices more than once ACPI / scan: Apply default enumeration to devices with ACPI drivers power: supply: axp288_charger: Only wait for INT3496 device if present ACPI / AC: Add a blacklist with PMIC ACPI HIDs with a native charger driver ACPI / battery: Add a blacklist with PMIC ACPI HIDs with a native battery driver ACPI / battery: Fix acpi_battery_exit on acpi_battery_init_async errors ACPI / utils: Add new acpi_dev_present helper ACPI / video: add comments about subtle cases ACPI / video: get rid of magic numbers and use enum instead ACPI / doc: linuxized-acpica.txt: fix typos ACPI / blacklist: add _REV quirk for Dell Inspiron 7537 ACPI / tables: Drop acpi_parse_entries() which is not used ACPI / CPPC: add sysfs entries for CPPC perf capabilities ACPI / CPPC: Read lowest nonlinear perf in cppc_get_perf_caps() ACPI / platform: Update platform device NUMA node based on _PXM method ACPI / Processor: Drop setup_max_cpus check from acpi_processor_add() ACPI / scan: Drop support for force_remove

Pull power management updates from Rafael Wysocki: "This time the majority of changes go to the cpufreq subsystem (and to the intel_pstate driver in particular) and there are some updates in the generic power domains framework, cpuidle, tools and a couple of other places. One thing worth mentioning is that the intel_pstate's sysfs interface has been reworked to be more consistent with the general expectations of the cpufreq core and less confusing, hopefully for the better. Also, we have a new cpufreq driver for Tegra186 and new hardware support in intel_pstata and the Mediatek cpufreq driver. Apart from that, the AnalyzeSuspend utility for system suspend profiling gets a companion called AnalyzeBoot for the analogous profiling of system boot and they both go into one place under tools/power/pm-graph/. The rest is mostly fixes, cleanups and code reorganization. Specifics: - Rework the intel_pstate driver's sysfs interface to make it more straightforward and more intuitive (Rafael Wysocki). - Make intel_pstate support all processors which advertise HWP (hardware-managed P-states) to the kernel in all operation modes and make it use the load-based P-state selection algorithm on a wider range of systems in the active mode (Rafael Wysocki). - Add cpufreq driver for Tegra186 (Mikko Perttunen). - Add support for Gemini Lake SoCs to intel_pstate (David Box). - Add support for MT8176 and MT817x to the Mediatek cpufreq driver and clean up that driver a bit (Daniel Kurtz). - Clean up intel_pstate and optimize it slightly (Rafael Wysocki). - Update the schedutil cpufreq governor, mostly to fix a couple of issues with it related to specific workloads, and rework its sysfs tunable and initialization a bit (Rafael Wysocki, Viresh Kumar). - Fix minor issues in the imx6q, dbx500 and qoriq cpufreq drivers (Christophe Jaillet, Irina Tirdea, Leonard Crestez, Viresh Kumar, YuanTian Tang). - Add file patterns for cpufreq DT bindings to MAINTAINERS (Geert Uytterhoeven). - Add support for "always on" power domains to the genpd (generic power domains) framework and clean up that code somewhat (Ulf Hansson, Lina Iyer, Viresh Kumar). - Fix minor issues in the powernv cpuidle driver and clean it up (Anton Blanchard, Gautham Shenoy). - Move the AnalyzeSuspend utility under tools/power/pm-graph/ and add an analogous boot-profiling utility called AnalyzeBoot to it (Todd Brandt). - Add rk3328 support to the rockchip-io AVS (Adaptive Voltage Scaling) driver (David Wu). - Fix minor issues in the cpuidle core, the intel_pstate_tracer utility, the devfreq framework and the PM core documentation (Chanwoo Choi, Doug Smythies, Johan Hovold, Marcin Nowakowski)" * tag 'pm-4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (56 commits) PM / runtime: Document autosuspend-helper side effects PM / runtime: Fix autosuspend documentation tools: power: pm-graph: Package makefile and man pages tools: power: pm-graph: AnalyzeBoot v2.0 tools: power: pm-graph: AnalyzeSuspend v4.6 cpufreq: Add Tegra186 cpufreq driver cpufreq: imx6q: Fix error handling code cpufreq: imx6q: Set max suspend_freq to avoid changes during suspend cpufreq: imx6q: Fix handling EPROBE_DEFER from regulator cpuidle: powernv: Avoid a branch in the core snooze_loop() loop cpuidle: powernv: Don't continually set thread priority in snooze_loop() cpuidle: powernv: Don't bounce between low and very low thread priority cpuidle: cpuidle-cps: remove unused variable tools/power/x86/intel_pstate_tracer: Adjust directory ownership cpufreq: schedutil: Use policy-dependent transition delays cpufreq: schedutil: Reduce frequencies slower PM / devfreq: Move struct devfreq_governor to devfreq directory PM / Domains: Ignore domain-idle-states that are not compatible cpufreq: intel_pstate: Add support for Gemini Lake powernv-cpuidle: Validate DT property array size ...

Pull block layer updates from Jens Axboe: - Add BFQ IO scheduler under the new blk-mq scheduling framework. BFQ was initially a fork of CFQ, but subsequently changed to implement fairness based on B-WF2Q+, a modified variant of WF2Q. BFQ is meant to be used on desktop type single drives, providing good fairness. From Paolo. - Add Kyber IO scheduler. This is a full multiqueue aware scheduler, using a scalable token based algorithm that throttles IO based on live completion IO stats, similary to blk-wbt. From Omar. - A series from Jan, moving users to separately allocated backing devices. This continues the work of separating backing device life times, solving various problems with hot removal. - A series of updates for lightnvm, mostly from Javier. Includes a 'pblk' target that exposes an open channel SSD as a physical block device. - A series of fixes and improvements for nbd from Josef. - A series from Omar, removing queue sharing between devices on mostly legacy drivers. This helps us clean up other bits, if we know that a queue only has a single device backing. This has been overdue for more than a decade. - Fixes for the blk-stats, and improvements to unify the stats and user windows. This both improves blk-wbt, and enables other users to register a need to receive IO stats for a device. From Omar. - blk-throttle improvements from Shaohua. This provides a scalable framework for implementing scalable priotization - particularly for blk-mq, but applicable to any type of block device. The interface is marked experimental for now. - Bucketized IO stats for IO polling from Stephen Bates. This improves efficiency of polled workloads in the presence of mixed block size IO. - A few fixes for opal, from Scott. - A few pulls for NVMe, including a lot of fixes for NVMe-over-fabrics. From a variety of folks, mostly Sagi and James Smart. - A series from Bart, improving our exposed info and capabilities from the blk-mq debugfs support. - A series from Christoph, cleaning up how handle WRITE_ZEROES. - A series from Christoph, cleaning up the block layer handling of how we track errors in a request. On top of being a nice cleanup, it also shrinks the size of struct request a bit. - Removal of mg_disk and hd (sorry Linus) by Christoph.

Pull x86 fixes from Thomas Gleixner: "The final fixes for 4.11: - prevent a triple fault with function graph tracing triggered via suspend to ram - prevent optimizing for size when function graph tracing is enabled and the compiler does not support -mfentry - prevent mwaitx() being called with a zero timeout as mwaitx() might never return. Observed on the new Ryzen CPUs" * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: Prevent timer value 0 for MWAITX x86/build: convert function graph '-Os' error to warning ftrace/x86: Fix triple fault with graph tracing and suspend-to-ram

Newer hardware has uncovered a bug in the software implementation of using MWAITX for the delay function. A value of 0 for the timer is meant to indicate that a timeout will not be used to exit MWAITX. On newer hardware this can result in MWAITX never returning, resulting in NMI soft lockup messages being printed. On older hardware, some of the other conditions under which MWAITX can exit masked this issue. The AMD APM does not currently document this and will be updated. Please refer to http://marc.info/?l=kvm&m=148950623231140 for information regarding NMI soft lockup messages on an AMD Ryzen 1800X. This has been root-caused as a 0 passed to MWAITX causing it to wait indefinitely. This change has the added benefit of avoiding the unnecessary setup of MONITORX/MWAITX when the delay value is zero.

This was already disabled a while ago because it caused I/O errors, and it's severly getting into the way of the discard / write zeroes rework. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Martin K. Petersen <martin.petersen@oracle.com> Signed-off-by: Tejun Heo <tj@kernel.org>

The WRITE SAME to TRIM translation rewrites the DATA OUT buffer. While the SCSI code accomodates for this by passing a read-writable buffer userspace applications don't cater for this behavior. In fact it can be used to rewrite e.g. a readonly file through mmap and should be considered as a security fix.
