      Pull SCSI updates from James Bottomley:
       "This update includes the usual round of driver updates (fcoe, lpfc,
        ufs, qla2xxx, hisi_sas).  The most important other change is removing
        the flag to allow non-blk_mq on a per host basis (it's unused); there
        is still a global module parameter for all of SCSI just in case.
      
        The rest are an assortment of minor fixes and typo updates"

      Linus Torvalds authored
      Pull spi updates from Mark Brown:
       "Quite a lot of cleanup and maintainence work going on this release in
        various drivers, and also a fix for a nasty locking issue in the core:
      
         - A fix for locking issues when external drivers explicitly locked
           the bus with spi_bus_lock() - we were using the same lock to both
           control access to the physical bus in multi-threaded I/O operations
           and exclude multiple callers.
      
           Confusion between these two caused us to have scenarios where we
           were dropping locks.  These are fixed by splitting into two
           separate locks like should have been done originally, making
           everything much clearer and correct.
      
         - Support for DMA in spi_flash_read().
      
         - Support for instantiating spidev on ACPI systems, including some
           test devices used in Windows validation.
      
         - Use of the core DMA mapping functionality in the McSPI driver.
      
         - Start of support for ThunderX SPI controllers, involving a very big
           set of changes to the Cavium driver.
      
         - Support for Braswell, Exynos 5433, Kaby Lake, Merrifield, RK3036,
           RK3228, RK3368 controllers"

      Disable "maybe-uninitialized" warning globally · 6e8d666e
      Linus Torvalds authored
      Several build configurations had already disabled this warning because
      it generates a lot of false positives.  But some had not, and it was
      still enabled for "allmodconfig" builds, for example.
      
      Looking at the warnings produced, every single one I looked at was a
      false positive, and the warnings are frequent enough (and big enough)
      that they can easily hide real problems that you don't notice in the
      noise generated by -Wmaybe-uninitialized.
      
      The warning is good in theory, but this is a classic case of a warning
      that causes more problems than the warning can solve.
      
      If gcc gets better at avoiding false positives, we may be able to
      re-enable this warning.  But as is, we're better off without it, and I
      want to be able to see the *real* warnings.

      ipmi: remove trydefaults parameter and default init · b07b58a3
      Tony Camuso authored
      Parameter trydefaults=1 causes the ipmi_init to initialize ipmi through
      the legacy port io space that was designated for ipmi. Architectures
      that do not map legacy port io can panic when trydefaults=1.
      
      Rather than implement build-time conditional exceptions for each
      architecture that does not map legacy port io, we have removed legacy
      port io from the driver.
      
      Parameter 'trydefaults' has been removed. Attempts to use it hereafter
      will evoke the "Unknown symbol in module, or unknown parameter" message.
      
      The patch was built against a number of architectures and tested for
      regressions and functionality on x86_64 and ARM64.

      be2net: perform temperature query in adapter regardless of its interface state · d3480615
      Guilherme G. Piccoli authored
      The be2net driver performs fw temperature queries on be_worker() routine,
      which is executed each second for each be_adapter. There is a frequency
      threshold to avoid fw query to happens at each call to be_worker();
      instead, currently a fw query occurs once in 64 runs of the procedure.
      
      Nevertheless, this fw temperature query is invoked only for adapters which
      interface is up, so we can see I/O errors on read of hwmon counters from
      userspace (from tools like lm-sensors) in case we have adapters' functions
      which interface is down.
      
      This patch moves the fw query code to be invoked even if interface is down.
      No functional changes were introduced.

      Pull GPIO updates from Linus Walleij:
       "This is the bulk of GPIO changes for the v4.8 kernel cycle.  The big
        news is the completion of the chardev ABI which I'm very happy about
        and apart from that it's an ordinary, quite busy cycle.  The details
        are below.
      
        The patches are tested in linux-next for some time, patches to other
        subsystem mostly have ACKs.
      
        I got overly ambitious with configureing lines as input for IRQ lines
        but it turns out that some controllers have their interrupt-enable and
        input-enabling in orthogonal settings so the assumption that all IRQ
        lines are input lines does not hold.  Oh well, revert and back to the
        drawing board with that.
      
        Core changes:
      
         - The big item is of course the completion of the character device
           ABI.  It has now replaced and surpassed the former unmaintainable
           sysfs ABI: we can now hammer (bitbang) individual lines or sets of
           lines and read individual lines or sets of lines from userspace,
           and we can also register to listen to GPIO events from userspace.
      
           As a tie-in we have two new tools in tools/gpio: gpio-hammer and
           gpio-event-mon that illustrate the proper use of the new ABI.  As
           someone said: the wild west days of GPIO are now over.
      
         - Continued to remove the pointless ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB
           Kconfig symbols.  I'm patching hexagon, openrisc, powerpc, sh,
           unicore, ia64 and microblaze.  These are either ACKed by their
           maintainers or patched anyways after a grace period and no response
           from maintainers.
      
           Some archs (ARM) come in from their trees, and others (x86) are
           still not fixed, so I might send a second pull request to root it
           out later in this merge window, or just defer to v4.9.
      
         - The GPIO tools are moved to the tools build system.
      
        New drivers:
      
         - New driver for the MAX77620/MAX20024.
      
         - New driver for the Intel Merrifield.
      
         - Enabled PCA953x for the TI PCA9536.
      
         - Enabled PCA953x for the Intel Edison.
      
         - Enabled R8A7792 in the RCAR driver.
      
        Driver improvements:
      
         - The STMPE and F7188x now supports the .get_direction() callback.
      
         - The Xilinx driver supports setting multiple lines at once.
      
         - ACPI support for the Vulcan GPIO controller.
      
         - The MMIO GPIO driver supports device tree probing.
      
         - The Acer One 10 is supported through the _DEP ACPI attribute.
      
        Cleanups:
      
         - A major cleanup of the OF/DT support code.  It is way easier to
           read and understand now, probably this improves performance too.
      
         - Drop a few redundant .owner assignments.
      
         - Remove CLPS711x boardfile support: we are 100% DT"

      Pull ACPI updates from Rafael Wysocki:
       "The new feaures here are the support for ACPI overlays (allowing ACPI
        tables to be loaded at any time from EFI variables or via configfs)
        and the LPI (Low-Power Idle) support.  Also notable is the ACPI-based
        NUMA support for ARM64.
      
        Apart from that we have two new drivers, for the DPTF (Dynamic Power
        and Thermal Framework) power participant device and for the Intel
        Broxton WhiskeyCove PMIC, some more PMIC-related changes, support for
        the Boot Error Record Table (BERT) in APEI and support for
        platform-initiated graceful shutdown.
      
        Plus two new pieces of documentation and usual assorted fixes and
        cleanups in quite a few places.
      
        Specifics:
      
         - Support for ACPI SSDT overlays allowing Secondary System
           Description Tables (SSDTs) to be loaded at any time from EFI
           variables or via configfs (Octavian Purdila, Mika Westerberg).
      
         - Support for the ACPI LPI (Low-Power Idle) feature introduced in
           ACPI 6.0 and allowing processor idle states to be represented in
           ACPI tables in a hierarchical way (with the help of Processor
           Container objects) and support for ACPI idle states management on
           ARM64, based on LPI (Sudeep Holla).
      
         - General improvements of ACPI support for NUMA and ARM64 support for
           ACPI-based NUMA (Hanjun Guo, David Daney, Robert Richter).
      
         - General improvements of the ACPI table upgrade mechanism and ARM64
           support for that feature (Aleksey Makarov, Jon Masters).
      
         - Support for the Boot Error Record Table (BERT) in APEI and
           improvements of kernel messages printed by the error injection code
           (Huang Ying, Borislav Petkov).
      
         - New driver for the Intel Broxton WhiskeyCove PMIC operation region
           and support for the REGS operation region on Broxton, PMIC code
           cleanups (Bin Gao, Felipe Balbi, Paul Gortmaker).
      
         - New driver for the power participant device which is part of the
           Dynamic Power and Thermal Framework (DPTF) and DPTF-related code
           reorganization (Srinivas Pandruvada).
      
         - Support for the platform-initiated graceful shutdown feature
           introduced in ACPI 6.1 (Prashanth Prakash).
      
         - ACPI button driver update related to lid input events generated
           automatically on initialization and system resume that have been
           problematic for some time (Lv Zheng).
      
         - ACPI EC driver cleanups (Lv Zheng).

           in-kernel ACPI AML debugger (Lv Zheng).

           (Alex Hung, Arvind Yadav, Ralf Gerbig).
      
         - Cleanups of the ACPI pci_slot driver (Joe Perches, Paul Gortmaker).
      
         - ACPI CPPC code changes to make it more robust against possible
           defects in ACPI tables and new symbol definitions for PCC (Hoan
           Tran).
      
         - System reboot code modification to execute the ACPI _PTS (Prepare
           To Sleep) method in addition to _TTS (Ocean He).
      
         - ACPICA-related change to carry out lock ordering checks in ACPICA
           if ACPICA debug is enabled in the kernel (Lv Zheng).

      Pull power management updates from Rafael  Wysocki:
       "Again, the majority of changes go into the cpufreq subsystem, but
        there are no big features this time.  The cpufreq changes that stand
        out somewhat are the governor interface rework and improvements
        related to the handling of frequency tables.  Apart from those, there
        are fixes and new device/CPU IDs in drivers, cleanups and an
        improvement of the new schedutil governor.
      
        Next, there are some changes in the hibernation core, including a fix
        for a nasty problem related to the MONITOR/MWAIT usage by CPU offline
        during resume from hibernation, a few core improvements related to
        memory management during resume, a couple of additional debug features
        and cleanups.
      
        Finally, we have some fixes and cleanups in the devfreq subsystem,
        generic power domains framework improvements related to system
        suspend/resume, support for some new chips in intel_idle and in the
        power capping RAPL driver, a new version of the AnalyzeSuspend utility
        and some assorted fixes and cleanups.
      
        Specifics:
      
         - Rework the cpufreq governor interface to make it more
           straightforward and modify the conservative governor to avoid using
           transition notifications (Rafael Wysocki).
      
         - Rework the handling of frequency tables by the cpufreq core to make
           it more efficient (Viresh Kumar).
      
         - Modify the schedutil governor to reduce the number of wakeups it
           causes to occur in cases when the CPU frequency doesn't need to be
           changed (Steve Muckle, Viresh Kumar).
      
         - Fix some minor issues and clean up code in the cpufreq core and
           governors (Rafael Wysocki, Viresh Kumar).
      
         - Add Intel Broxton support to the intel_pstate driver (Srinivas
           Pandruvada).
      
         - Fix problems related to the config TDP feature and to the validity
           of the MSR_HWP_INTERRUPT register in intel_pstate (Jan Kiszka,
           Srinivas Pandruvada).
      
         - Make intel_pstate update the cpu_frequency tracepoint even if the
           frequency doesn't change to avoid confusing powertop (Rafael
           Wysocki).
      
         - Clean up the usage of __init/__initdata in intel_pstate, mark some
           of its internal variables as __read_mostly and drop an unused
           structure element from it (Jisheng Zhang, Carsten Emde).
      
         - Clean up the usage of some duplicate MSR symbols in intel_pstate
           and turbostat (Srinivas Pandruvada).
      
         - Update/fix the powernv, s3c24xx and mvebu cpufreq drivers (Akshay
           Adiga, Viresh Kumar, Ben Dooks).
      
         - Fix a regression (introduced during the 4.5 cycle) in the
           pcc-cpufreq driver by reverting the problematic commit (Andreas
           Herrmann).
      
         - Add support for Intel Denverton to intel_idle, clean up Broxton
           support in it and make it explicitly non-modular (Jacob Pan, Jan
           Beulich, Paul Gortmaker).
      
         - Add support for Denverton and Ivy Bridge server to the Intel RAPL
           power capping driver and make it more careful about the handing of
           MSRs that may not be present (Jacob Pan, Xiaolong Wang).
      
         - Fix resume from hibernation on x86-64 by making the CPU offline
           during resume avoid using MONITOR/MWAIT in the "play dead" loop
           which may lead to an inadvertent "revival" of a "dead" CPU and a
           page fault leading to a kernel crash from it (Rafael Wysocki).
      
         - Make memory management during resume from hibernation more
           straightforward (Rafael Wysocki).
      
         - Add debug features that should help to detect problems related to
           hibernation and resume from it (Rafael Wysocki, Chen Yu).
      
         - Clean up hibernation core somewhat (Rafael Wysocki).
      
         - Prevent KASAN from instrumenting the hibernation core which leads
           to large numbers of false-positives from it (James Morse).
      
         - Prevent PM (hibernate and suspend) notifiers from being called
           during the cleanup phase if they have not been called during the
           corresponding preparation phase which is possible if one of the
           other notifiers returns an error at that time (Lianwei Wang).
      
         - Improve suspend-related debug printout in the tasks freezer and
           clean up suspend-related console handling (Roger Lu, Borislav
           Petkov).
      
         - Update the AnalyzeSuspend script in the kernel sources to version
           4.2 (Todd Brandt).
      
         - Modify the generic power domains framework to make it handle system
           suspend/resume better (Ulf Hansson).
      
         - Make the runtime PM framework avoid resuming devices synchronously
           when user space changes the runtime PM settings for them and
           improve its error reporting (Rafael Wysocki, Linus Walleij).
      
         - Fix error paths in devfreq drivers (exynos, exynos-ppmu,
           exynos-bus) and in the core, make some devfreq code explicitly
           non-modular and change some of it into tristate (Bartlomiej
           Zolnierkiewicz, Peter Chen, Paul Gortmaker).
      
         - Add DT support to the generic PM clocks management code and make it
           export some more symbols (Jon Hunter, Paul Gortmaker).
      
         - Make the PCI PM core code slightly more robust against possible
           driver errors (Andy Shevchenko).
      
         - Make it possible to change DESTDIR and PREFIX in turbostat (Andy
           Shevchenko)"

      Pull device mapper updates from Mike Snitzer:
      
       - initially based on Jens' 'for-4.8/core' (given all the flag churn)
         and later merged with 'for-4.8/core' to pickup the QUEUE_FLAG_DAX
         commits that DM depends on to provide its DAX support
      
       - clean up the bio-based vs request-based DM core code by moving the
         request-based DM core code out to dm-rq.[hc]
      
       - reinstate bio-based support in the DM multipath target (done with the
         idea that fast storage like NVMe over Fabrics could benefit) -- while
         preserving support for request_fn and blk-mq request-based DM mpath
      
       - SCSI and DM multipath persistent reservation fixes that were
         coordinated with Martin Petersen.
      
       - the DM raid target saw the most extensive change this cycle; it now
         provides reshape and takeover support (by layering ontop of the
         corresponding MD capabilities)
      
       - DAX support for DM core and the linear, stripe and error targets
      
       - a DM thin-provisioning block discard vs allocation race fix that
         addresses potential for corruption
      
       - a stable fix for DM verity-fec's block calculation during decode
      
       - a few cleanups and fixes to DM core and various targets
