      Pull block layer updates from Jens Axboe:
      
       - blk-mq scheduling framework from me and Omar, with a port of the
         deadline scheduler for this framework. A port of BFQ from Paolo is in
         the works, and should be ready for 4.12.
      
       - Various fixups and improvements to the above scheduling framework
         from Omar, Paolo, Bart, me, others.
      
       - Cleanup of the exported sysfs blk-mq data into debugfs, from Omar.
         This allows us to export more information that helps debug hangs or
         performance issues, without cluttering or abusing the sysfs API.
      
       - Fixes for the sbitmap code, the scalable bitmap code that was
         migrated from blk-mq, from Omar.
      
       - Removal of the BLOCK_PC support in struct request, and refactoring of
         carrying SCSI payloads in the block layer. This cleans up the code
         nicely, and enables us to kill the SCSI specific parts of struct
         request, shrinking it down nicely. From Christoph mainly, with help
         from Hannes.
      
       - Support for ranged discard requests and discard merging, also from
         Christoph.
      
       - Support for OPAL in the block layer, and for NVMe as well. Mainly
         from Scott Bauer, with fixes/updates from various others folks.
      
       - Error code fixup for gdrom from Christophe.
      
       - cciss pci irq allocation cleanup from Christoph.
      
       - Making the cdrom device operations read only, from Kees Cook.
      
       - Fixes for duplicate bdi registrations and bdi/queue life time
         problems from Jan and Dan.
      
       - Set of fixes and updates for lightnvm, from Matias and Javier.
      
       - A few fixes for nbd from Josef, using idr to name devices and a
         workqueue deadlock fix on receive. Also marks Josef as the current
         maintainer of nbd.
      
       - Fix from Josef, overwriting queue settings when the number of
         hardware queues is updated for a blk-mq device.
      
       - NVMe fix from Keith, ensuring that we don't repeatedly mark and IO
         aborted, if we didn't end up aborting it.
      
       - SG gap merging fix from Ming Lei for block.
      
       - Loop fix also from Ming, fixing a race and crash between setting loop
         status and IO.
      
       - Two block race fixes from Tahsin, fixing request list iteration and
         fixing a race between device registration and udev device add
         notifiations.
      
       - Double free fix from cgroup writeback, from Tejun.
      
       - Another double free fix in blkcg, from Hou Tao.
      
       - Partition overflow fix for EFI from Alden Tondettar.

      sched/core: Fix build paravirt build on arm and arm64 · fd4a61e0
      Mark Brown authored
      Commit 004172bd ("sched/core: Remove unnecessary #include headers")
      removed the inclusion of asm/paravirt.h which is used to get
      declarations of paravirt_steal_rq_enabled and paravirt_steal_clock.
      
      It is implicitly included on x86 but not on arm and arm64 breaking the
      build if paravirtualization is used.  Since things from that header are
      used directly fix the build by putting the direct inclusion back.

      Linus Torvalds authored
      Pull GFS2 updates from Robert Peterson:
       "We've got eight GFS2 patches for this merge window:
      
         - Andy Price submitted a patch to make gfs2_write_full_page a static
           function.
      
         - Dan Carpenter submitted a patch to fix a ERR_PTR thinko.
      
        Three patches fix bugs related to deleting very large files, which
        cause GFS2 to run out of journal space:
      
         - The first one prevents GFS2 delete operation from requesting too
           much journal space.
      
         - The second one fixes a problem whereby GFS2 can hang because it
           wasn't taking journal space demand into its calculations.
      
         - The third one wakes up IO waiters when a flush is done to restart
           processes stuck waiting for journal space to become available.
      
        The final three patches are a performance improvement related to
        spin_lock contention between multiple writers:
      
         - The "tr_touched" variable was switched to a flag to be more atomic
           and eliminate the possibility of some races.
      
         - Function meta_lo_add was moved inline with its only caller to make
           the code more readable and efficient.
      
         - Contention on the gfs2_log_lock spinlock was greatly reduced by
           avoiding the lock altogether in cases where we don't really need
           it: buffers that already appear in the appropriate metadata list
           for the journal. Many thanks to Steve Whitehouse for the ideas and
           principles behind these patches"

      Pull ext4 updates from Ted Ts'o:
       "For this cycle we add support for the shutdown ioctl, which is
        primarily used for testing, but which can be useful on production
        systems when a scratch volume is being destroyed and the data on it
        doesn't need to be saved.
      
        This found (and we fixed) a number of bugs with ext4's recovery to
        corrupted file system --- the bugs increased the amount of data that
        could be potentially lost, and in the case of the inline data feature,
        could cause the kernel to BUG.

        framework and cpufreq this time, followed by devfreq and some
        scattered updates all over.
      
        The OPP changes are mostly related to switching over from RCU-based
        synchronization, that turned out to be overly complicated and
        problematic, to reference counting using krefs.
      
        In the cpufreq land there are core cleanups, documentation updates, a
        new driver for Broadcom BMIPS SoCs, a new cpufreq-dt sub-driver for TI
        SoCs that require special handling, ARM64 SoCs support for the qoriq
        driver, intel_pstate updates, powernv driver update and assorted
        fixes.
      
        The devfreq changes are mostly fixes related to the sysfs interface
        and some Exynos drivers updates.
      
        Apart from that, the cpuidle menu governor will support per-CPU PM QoS
        constraints for the wakeup latency now, some bugs in the wakeup IRQs
        framework are fixed, the generic power domains framework should handle
        asynchronous invocations of *noirq suspend/resume callbacks from now
        on, the analyze_suspend.py script is updated and there is a new tool
        for intel_pstate diagnostics.
      
        Specifics:
      
         - Operating Performance Points (OPP) framework fixes, cleanups and
           switch over from RCU-based synchronization to reference counting
           using krefs (Viresh Kumar, Wei Yongjun, Dave Gerlach)

           new DT bindings for it (Dave Gerlach, Paul Gortmaker)
      
         - ARM64 SoCs support for the qoriq cpufreq driver (Tang Yuantian)
      
         - intel_pstate driver updates including a new sysfs knob to control
           the driver's operation mode and fixes related to the no_turbo sysfs
           knob and the hardware-managed P-states feature support (Rafael
           Wysocki, Srinivas Pandruvada)
      
         - New interface to export ultra-turbo frequencies for the powernv
           cpufreq driver (Shilpasri Bhat)
      
         - Assorted fixes for cpufreq drivers (Arnd Bergmann, Dan Carpenter,
           Wei Yongjun)
      
         - devfreq core fixes, mostly related to the sysfs interface exported
           by it (Chanwoo Choi, Chris Diamand)
      
         - Updates of the exynos-bus and exynos-ppmu devfreq drivers (Chanwoo
           Choi)

           QoS framework and x86 ACPI idle support code (Corentin Labbe, Geert
           Uytterhoeven, Geliang Tang, John Keeping, Nick Desaulniers)
      
         - Update of the analyze_suspend.py script is updated to version 4.5
           offering multiple improvements (Todd Brandt)
      
         - New tool for intel_pstate diagnostics using the pstate_sample
           tracepoint (Doug Smythies)"

       "New features and improvements:
      
         - add new optional brightness_hw_changed attribute for the LEDs that
           may have their brightness level changed autonomously (outside of
           kernel control) by hardware / firmware. The attribute supports
           userspace notifications through POLLPRI events
      
         - add led_brightness_hw_mon tool that demonstrates how to use the
           aforementioned feature
      
         - add LED_ON enum for LEDs that can be only turned on/off, and don't
           allow setting other brightness levels
      
         - allow for adjusting heartbeat trigger blink brightness level

       "On the kernel side the main changes in this cycle were:
      
         - Add Intel Kaby Lake CPU support (Srinivas Pandruvada)
      
         - AMD uncore driver updates for fam17 (Janakarajan Natarajan)
      
         - Intel/PT updates and core events optimizations and cleanups

         - kprobes improvements (Masami Hiramatsu)
      
         - ... plus misc fixes and updates.
      
        On the tooling side the main changes were:
      
         - Support clang build in tools/{perf,lib/{bpf,traceevent,api}} with
           CC=clang, to, for instance, take advantage of better warnings
           (Arnaldo Carvalho de Melo):
      
         - Introduce the 'delta-abs' 'perf diff' compute method, that orders
           the histogram entries by the absolute value of the percentage delta
           for a function in two perf.data files, i.e. the functions that
           changed the most (increase or decrease in samples) comes first
           (Namhyung Kim)
      
         - Add support for parsing Intel uncore vendor event files and add
           uncore vendor events for the Intel server processors (Haswell,
           Broadwell, IvyBridge), Xeon Phi (Knights Landing) and Broadwell DE
           (Andi Kleen)
      
         - Introduce 'perf ftrace' a perf front end to the kernel's ftrace
           function and function_graph tracer, defaulting to the
           "function_graph" tracer, more work will be done in reviving this
           effort, forward porting it from its initial patch submission
           (Namhyung Kim)
      
         - Add 'e' and 'c' hotkeys to expand/collapse call chains for a single
           hist entry in the 'perf report' and 'perf top' TUI (Jiri Olsa)
      
         - Account thread wait time (off CPU time) separately: sleep, iowait
           and preempt, based on the prev_state of the last event, show the
           breakdown when using "perf sched timehist --state" (Namhyumg Kim)
      
         - Add more triggers to switch the output file (perf.data.TIMESTAMP).
      
           Now, in addition to switching to a different output file when
           receiving a SIGUSR2, one can also specify file size and time based
           triggers:
      
                 perf record -a --switch-output=signal
      
           is equivalent to what we had before:
      
                 perf record -a --switch-output
      
           While we can also ask for the file to be "sliced" by size, taking
           into account that that will happen only when we get woken up by the
           kernel, i.e. one has to take into account the --mmap-pages (the
           size of the perf mmap ring buffer):
      
                 perf record -a --switch-output=2G
      
           will break the perf.data output into multiple files limited to 2GB
           of samples, right when generating the output.
      
           For time based samples, alert() will be used, so to have 1 minute
           limited perf.data output files:
      
                perf record -a --switch-output=1m
      
           (Jiri Olsa)
      
         - Improve 'perf trace' (Arnaldo Carvalho de Melo)
      
         - 'perf kallsyms' toy tool to look for extended symbol information on
           the running kernel and demonstrate the machine/thread/symbol APIs
           for use in other tools, such as 'perf probe' (Arnaldo Carvalho de
           Melo)
