      Linus Torvalds authored
      Pull perf updates from Ingo Molnar:
       "Kernel side changes:
      
         - Clean up the x86 instruction decoder (Masami Hiramatsu)
      
         - Add new uprobes optimization for PUSH instructions on x86 (Yonghong
           Song)
      
         - Add MSR_IA32_THERM_STATUS to the MSR events (Stephane Eranian)
      
         - Fix misc bugs, update documentation, plus various cleanups (Jiri
           Olsa)
      
        There's a large number of tooling side improvements:
      
         - Intel-PT/BTS improvements (Adrian Hunter)
      
         - Numerous 'perf trace' improvements (Arnaldo Carvalho de Melo)
      
         - Introduce an errno code to string facility (Hendrik Brueckner)
      
         - Various build system improvements (Jiri Olsa)
      
         - Add support for CoreSight trace decoding by making the perf tools
           use the external openCSD (Mathieu Poirier, Tor Jeremiassen)
      
         - Add ARM Statistical Profiling Extensions (SPE) support (Kim
           Phillips)
      
         - libtraceevent updates (Steven Rostedt)
      
         - Intel vendor event JSON updates (Andi Kleen)
      
         - Introduce 'perf report --mmaps' and 'perf report --tasks' to show
           info present in 'perf.data' (Jiri Olsa, Arnaldo Carvalho de Melo)
      
         - Add infrastructure to record first and last sample time to the
           perf.data file header, so that when processing all samples in a
           'perf record' session, such as when doing build-id processing, or
           when specifically requesting that that info be recorded, use that
           in 'perf report --time', that also got support for percent slices
           in addition to absolute ones.
      
           I.e. now it is possible to ask for the samples in the 10%-20% time
           slice of a perf.data file (Jin Yao)
      
         - Allow system wide 'perf stat --per-thread', sorting the result (Jin
           Yao)
      
           E.g.:
      
            [root@jouet ~]# perf stat --per-thread --metrics IPC
            ^C

       "The timer departement presents:
      
         - A rather large rework of the hrtimer infrastructure which
           introduces softirq based hrtimers to replace the spread of
           hrtimer/tasklet combos which force the actual callback execution
           into softirq context. The approach is completely different from the
           initial implementation which you cursed at 10 years ago rightfully.
      
           The softirq based timers have their own queues and there is no
           nasty indirection and list reshuffling in the hard interrupt
           anymore. This comes with conversion of some of the hrtimer/tasklet
           users, the rest and the final removal of that horrible interface
           will come towards the end of the merge window or go through the
           relevant maintainer trees.
      
           Note: The top commit merged the last minute bugfix for the 10 years
           old CPU hotplug bug as I wanted to make sure that I fatfinger the

      Pull inode->i_version rework from Jeff Layton:
       "This pile of patches is a rework of the inode->i_version field. We
        have traditionally incremented that field on every inode data or
        metadata change. Typically this increment needs to be logged on disk
        even when nothing else has changed, which is rather expensive.
      
        It turns out though that none of the consumers of that field actually
        require this behavior. The only real requirement for all of them is
        that it be different iff the inode has changed since the last time the
        field was checked.
      
        Given that, we can optimize away most of the i_version increments and
        avoid dirtying inode metadata when the only change is to the i_version
        and no one is querying it. Queries of the i_version field are rather
        rare, so we can help write performance under many common workloads.
      
        This patch series converts existing accesses of the i_version field to
        a new API, and then converts all of the in-kernel filesystems to use
        it. The last patch in the series then converts the backend
        implementation to a scheme that optimizes away a large portion of the
        metadata updates when no one is looking at it.
      
        In my own testing this series significantly helps performance with
        small I/O sizes. I also got this email for Christmas this year from
        the kernel test robot (a 244% r/w bandwidth improvement with XFS over
        DAX, with 4k writes):

       "This is the main pull request for block IO related changes for the
        4.16 kernel. Nothing major in this pull request, but a good amount of
        improvements and fixes all over the map. This contains:
      
         - BFQ improvements, fixes, and cleanups from Angelo, Chiara, and
           Paolo.
      
         - Support for SMR zones for deadline and mq-deadline from Damien and
           Christoph.
      
         - Set of fixes for bcache by way of Michael Lyle, including fixes
           from himself, Kent, Rui, Tang, and Coly.
      
         - Series from Matias for lightnvm with fixes from Hans Holmberg,
           Javier, and Matias. Mostly centered around pblk, and the removing
           rrpc 1.2 in preparation for supporting 2.0.
      
         - A couple of NVMe pull requests from Christoph. Nothing major in
           here, just fixes and cleanups, and support for command tracing from
           Johannes.
      
         - Support for blk-throttle for tracking reads and writes separately.
           From Joseph Qi. A few cleanups/fixes also for blk-throttle from
           Weiping.
      
         - Series from Mike Snitzer that enables dm to register its queue more
           logically, something that's alwways been problematic on dm since
           it's a stacked device.
      
         - Series from Ming cleaning up some of the bio accessor use, in
           preparation for supporting multipage bvecs.
      
         - Various fixes from Ming closing up holes around queue mapping and
           quiescing.
      
         - BSD partition fix from Richard Narron, fixing a problem where we
           can't mount newer (10/11) FreeBSD partitions.
      
         - Series from Tejun reworking blk-mq timeout handling. The previous
           scheme relied on atomic bits, but it had races where we would think
           a request had timed out if it to reused at the wrong time.
      
         - null_blk now supports faking timeouts, to enable us to better
           exercise and test that functionality separately. From me.
      
         - Kill the separate atomic poll bit in the request struct. After
           this, we don't use the atomic bits on blk-mq anymore at all. From
           me.
      
         - sgl_alloc/free helpers from Bart.
      
         - Heavily contended tag case scalability improvement from me.
      
         - Various little fixes and cleanups from Arnd, Bart, Corentin,
           Douglas, Eryu, Goldwyn, and myself"

      Linus Torvalds authored
      Pull MMC updates from Ulf Hansson:
       "There are two major achievements for MMC in this release, which
        deserves to be specially highlighted.
      
        First, we have converted the MMC block device from using the legacy
        blk interface into using the modern blkmq interface. Not only do we
        get all the nice effects from using blkmq, but it also means that new
        fresh nice code replaces old rusty code. Great news to everybody that
        cares about MMC/SD!
      
        It should also be noted that converting to blkmq has not been trivial,
        mostly because of that we have been carrying too much of MMC specific
        optimizations for the I/O request path, rather than striving to move
        these to the generic blk layer. Hopefully we won't be doing that
        mistake, ever again.
      
        Special thanks to Adrian Hunter (Intel) and to Linus Walleij (Linaro),
        who both have been working on this for quite some time!
      
        Second, on top of the blkmq deployment, we have enabled full support
        the eMMC command queuing feature, introduced in the eMMC v.5.1 spec.
        This also includes an implementation of a host driver library,
        supporting the corresponding CQHCI HW. Ideally, those controllers that
        supports CQHCI should only need some minor adaptations to make this
        play.
      
        So far the sdhci-pci driver for the Intel GLKs and the sdhci-of-arasan
        driver used on Rockchip RK3399, have enabled support for eMMC command
        queueing.
      
        Worth to highlight is also that, implementing the eMMC command queuing
        support has been a collaborative effort, as several people from
        Codeaurora, Rockchip, Intel and Linaro have been involved. However,
        the work has been driven by Adrian Hunter (Intel).
      
        In some shadow of the above, here are the rest of the highlights:
      
        MMC core:
         - Don't remove non-removable cards during system suspend
         - Add a slot-gpio helper to check capability of GPIO WP detection
      
        MMC host:
         - sdhci: Cleanups and improvements of some wakeup related code
         - sdhci-pci-arasan: New variant to support Arasan PCI HW with integrated phy
         - sdhci-acpi: Avoid broken UHS transfer modes on Intel CHT
         - sdhci-acpi: Add support for ACPI HID of AMD Controller with HS400
         - sdhci_f_sdh30: Add ACPI support
         - sdhci-esdhc-imx: Enable/disable clock at runtime suspend/resume
         - sdhci-of-esdhc: A few minor fixes
         - mmci: Add support for new STM32 variant
         - renesas_sdhi: enable R-Car D3 (r8a77995) support

      Pull power management updates from Rafael Wysocki:
       "This includes some infrastructure changes in the PM core, mostly
        related to integration between runtime PM and system-wide suspend and
        hibernation, plus some driver changes depending on them and fixes for
        issues in that area which have become quite apparent recently.
      
        Also included are changes making more x86-based systems use the Low
        Power Sleep S0 _DSM interface by default, which turned out to be
        necessary to handle power button wakeups from suspend-to-idle on
        Surface Pro3.
      
        On the cpufreq front we have fixes and cleanups in the core, some new
        hardware support, driver updates and the removal of some unused code
        from the CPU cooling thermal driver.
      
        Apart from this, the Operating Performance Points (OPP) framework is
        prepared to be used with power domains in the future and there is a
        usual bunch of assorted fixes and cleanups.
      
        Specifics:
      
         - Define a PM driver flag allowing drivers to request that their
           devices be left in suspend after system-wide transitions to the
           working state if possible and add support for it to the PCI bus
           type and the ACPI PM domain (Rafael Wysocki).
      
         - Make the PM core carry out optimizations for devices with driver PM
           flags set in some cases and make a few drivers set those flags
           (Rafael Wysocki).
      
         - Fix and clean up wrapper routines allowing runtime PM device
           callbacks to be re-used for system-wide PM, change the generic
           power domains (genpd) framework to stop using those routines
           incorrectly and fix up a driver depending on that behavior of genpd
           (Rafael Wysocki, Ulf Hansson, Geert Uytterhoeven).
      
         - Fix and clean up the PM core's device wakeup framework and
           re-factor system-wide PM core code related to device wakeup
           (Rafael Wysocki, Ulf Hansson, Brian Norris).
      
         - Make more x86-based systems use the Low Power Sleep S0 _DSM
           interface by default (to fix power button wakeup from
           suspend-to-idle on Surface Pro3) and add a kernel command line
           switch to tell it to ignore the system sleep blacklist in the ACPI
           core (Rafael Wysocki).
      
         - Fix a race condition related to cpufreq governor module removal and
           clean up the governor management code in the cpufreq core (Rafael
           Wysocki).
      
         - Drop the unused generic code related to the handling of the static
           power energy usage model in the CPU cooling thermal driver along
           with the corresponding documentation (Viresh Kumar).
      
         - Add mt2712 support to the Mediatek cpufreq driver (Andrew-sh
           Cheng).
      
         - Add a new operating point to the imx6ul and imx6q cpufreq drivers
           and switch the latter to using clk_bulk_get() (Anson Huang, Dong
           Aisheng).
      
         - Add support for multiple regulators to the TI cpufreq driver along
           with a new DT binding related to that and clean up that driver
           somewhat (Dave Gerlach).
      
         - Fix a powernv cpufreq driver regression leading to incorrect CPU
           frequency reporting, fix that driver to deal with non-continguous
           P-states correctly and clean it up (Gautham Shenoy, Shilpasri
           Bhat).
      
         - Add support for frequency scaling on Armada 37xx SoCs through the
           generic DT cpufreq driver (Gregory CLEMENT).
      
         - Fix error code paths in the mvebu cpufreq driver (Gregory CLEMENT).
      
         - Fix a transition delay setting regression in the longhaul cpufreq
           driver (Viresh Kumar).
      
         - Add Skylake X (server) support to the intel_pstate cpufreq driver
           and clean up that driver somewhat (Srinivas Pandruvada).
      
         - Clean up the cpufreq statistics collection code (Viresh Kumar).
      
         - Drop cluster terminology and dependency on physical_package_id from
           the PSCI driver and drop dependency on arm_big_little from the SCPI
           cpufreq driver (Sudeep Holla).
      
         - Add support for system-wide suspend and resume to the RAPL power
           capping driver and drop a redundant semicolon from it (Zhen Han,
           Luis de Bethencourt).
      
         - Make SPI domain validation (in the SCSI SPI transport driver) and
           system-wide suspend mutually exclusive as they rely on the same
           underlying mechanism and cannot be carried out at the same time
           (Bart Van Assche).
      
         - Fix the computation of the amount of memory to preallocate in the
           hibernation core and clean up one function in there (Rainer Fiebig,
           Kyungsik Lee).
      
         - Prepare the Operating Performance Points (OPP) framework for being
           used with power domains and clean up one function in it (Viresh
           Kumar, Wei Yongjun).
      
         - Clean up the generic sysfs interface for device PM (Andy
           Shevchenko).
      
         - Fix several minor issues in power management frameworks and clean
           them up a bit (Arvind Yadav, Bjorn Andersson, Geert Uytterhoeven,
           Gustavo Silva, Julia Lawall, Luis de Bethencourt, Paul Gortmaker,
           Sergey Senozhatsky, gaurav jindal).
      
         - Make it easier to disable PM via Kconfig (Mark Brown).
      
         - Clean up the cpupower and intel_pstate_tracer utilities (Doug
           Smythies, Laura Abbott)"

      Pull init_task initializer cleanups from David Howells:
       "It doesn't seem useful to have the init_task in a header file rather
        than in a normal source file. We could consolidate init_task handling
        instead and expand out various macros.
      
        Here's a series of patches that consolidate init_task handling:
      
         (1) Make THREAD_SIZE available to vmlinux.lds for cris, hexagon and
             openrisc.
      
         (2) Alter the INIT_TASK_DATA linker script macro to set
             init_thread_union and init_stack rather than defining these in C.
      
             Insert init_task and init_thread_into into the init_stack area in
             the linker script as appropriate to the configuration, with
             different section markers so that they end up correctly ordered.
      
             We can then get merge ia64's init_task.c into the main one.
      
             We then have a bunch of single-use INIT_*() macros that seem only
             to be macros because they used to be used per-arch. We can then
             expand these in place of the user and get rid of a few lines and
             a lot of backslashes.
      
         (3) Expand INIT_TASK() in place.
      
         (4) Expand in place various small INIT_*() macros that are defined
             conditionally. Expand them and surround them by #if[n]def/#endif
             in the .c file as it takes fewer lines.
      
         (5) Expand INIT_SIGNALS() and INIT_SIGHAND() in place.
      
         (6) Expand INIT_STRUCT_PID in place.
      
        These macros can then be discarded"
      
      * tag 'init_task-20180117' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs:
