      Pull AVR32 removal from Hans-Christian Noren Egtvedt:
       "This will remove support for AVR32 architecture from the kernel and
        clean away the most obvious architecture related parts. Removing dead
        code in drivers is the next step"
      
      Notes from previous discussion about this:
       "The AVR32 architecture is not keeping up with the development of the
        kernel, and since it shares so much of the drivers with Atmel ARM SoC,
        it is starting to hinder these drivers to develop swiftly.
      
        Also, all AVR32 AP7 SoC processors are end of lifed from Atmel (now
        Microchip).
      
        Finally, the GCC toolchain is stuck at version 4.2.x, and has not
        received any patches since the last release from Atmel;
        4.2.4-atmel.1.1.3.avr32linux.1.
      
        When building kernel v4.10, this toolchain is no longer able to
        properly link the network stack.
      
        Haavard and I have came to the conclusion that we feel keeping AVR32
        on life support offers more obstacles for Atmel ARMs, than it gives
        joy to AVR32 users. I also suspect there are very few AVR32 users left
        today, if anybody at all"
      
      That discussion was acked by Andy Shevchenko, Boris Brezillon, Nicolas
      Ferre, and Haavard Skinnemoen.

      ia64: fix module loading for gcc-5.4 · a25fb850
      Sergei Trofimovich authored
      Starting from gcc-5.4+ gcc generates MLX instructions in more cases to
      refer local symbols:
      
          https://gcc.gnu.org/PR60465
      
      That caused ia64 module loader to choke on such instructions:
      
          fuse: invalid slot number 1 for IMM64
      
      The Linux kernel used to handle only case where relocation pointed to
      slot=2 instruction in the bundle.  That limitation was fixed in linux by
      commit 9c184a07 ("[IA64] Fix 2.6 kernel for the new ia64 assembler")
      See
      
          http://sources.redhat.com/bugzilla/show_bug.cgi?id=1433
      
      This change lifts the slot=2 restriction from the kernel module loader.
      
      Tested on 'fuse' and 'btrfs' kernel modules.

      Pull uaccess unification updates from Al Viro:
       "This is the uaccess unification pile. It's _not_ the end of uaccess
        work, but the next batch of that will go into the next cycle. This one
        mostly takes copy_from_user() and friends out of arch/* and gets the
        zero-padding behaviour in sync for all architectures.
      
        Dealing with the nocache/writethrough mess is for the next cycle;
        fortunately, that's x86-only. Same for cleanups in iov_iter.c (I am

      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)"

      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)"

      cgroup: mark cgroup_get() with __maybe_unused · 310b4816
      Tejun Heo authored
      a590b90d ("cgroup: fix spurious warnings on cgroup_is_dead() from
      cgroup_sk_alloc()") converted most cgroup_get() usages to
      cgroup_get_live() leaving cgroup_sk_alloc() the sole user of
      cgroup_get().  When !CONFIG_SOCK_CGROUP_DATA, this ends up triggering
      unused warning for cgroup_get().
      
      Silence the warning by adding __maybe_unused to cgroup_get().

      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. The former was
         never used by platforms, and the latter has outlived it's usefulness.

      avr32: remove support for AVR32 architecture · 26202873
      Hans-Christian Noren Egtvedt authored
      This patch drops support for AVR32 architecture from the Linux kernel.
      
      The AVR32 architecture is not keeping up with the development of the
      kernel, and since it shares so much of the drivers with Atmel ARM SoC,
      it is starting to hinder these drivers to develop swiftly.
      
      Also, all AVR32 AP7 SoC processors are end of lifed from Atmel (now
      Microchip).
      
      Finally, the GCC toolchain is stuck at version 4.2.x, and has not
      received any patches since the last release from Atmel;
      4.2.4-atmel.1.1.3.avr32linux.1. When building kernel v4.10, this
      toolchain is no longer able to properly link the network stack.
      
      Haavard and I have came to the conclusion that we feel keeping AVR32 on
      life support offers more obstacles for Atmel ARMs, than it gives joy to
      AVR32 users. I also suspect there are very few AVR32 users left today,
      if anybody at all.
