      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)"

      ACPI / power: Delay turning off unused power resources after suspend · 8ece1d83
      Hans de Goede authored
      Commit 660b1113 (ACPI / PM: Fix consistency check for power resources
      during resume) introduced a check for ACPI power resources which have
      been turned on by the BIOS during suspend and turns these back off again.
      
      This is causing problems on a Dell Venue Pro 11 7130 (i5-4300Y) it causes
      the following messages to show up in dmesg:
      
      [  131.014605] ACPI: Waking up from system sleep state S3
      [  131.150271] acpi LNXPOWER:07: Turning OFF
      [  131.150323] acpi LNXPOWER:06: Turning OFF
      [  131.150911] acpi LNXPOWER:00: Turning OFF
      [  131.169014] ACPI : EC: interrupt unblocked
      [  131.181811] xhci_hcd 0000:00:14.0: System wakeup disabled by ACPI
      [  133.535728] pci_raw_set_power_state: 76 callbacks suppressed
      [  133.535735] iwlwifi 0000:01:00.0: Refused to change power state,
                     currently in D3
      [  133.597672] PM: noirq resume of devices complete after 2428.891 msecs
      
      Followed by a bunch of iwlwifi errors later on and the pcie device
      dropping from the bus (acpiphp thinks it has been unplugged).
      
      Disabling the turning off of unused power resources fixes this. Instead
      of adding a quirk for this system, this commit fixes this by moving the
      disabling of unused power resources to later in the resume sequence
      when the iwlwifi card has been moved out of D3 so the ref_count for
      its power resource no longer is 0.
      
      This new behavior seems to match the intend of the original commit which
      commit-msg says: "(... which means that no devices are going to need them
      any time soon) and we should turn them off".
      
      This also avoids power resources which we need when bringing devices out
      of D3 from getting bounced off and then back on again.

      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.
      
       - Various little bug fixes and cleanups from a wide variety of folks.

      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.

      ACPI / PMIC: xpower: Fix power_table addresses · 2bde7c32
      Hans de Goede authored
      The power table addresses should be contiguous, but there was a hole
      where 0x34 was missing. On most devices this is not a problem as
      addresses above 0x34 are used for the BUC# convertors which are not
      used in the DSDTs I've access to but after the BUC# convertors
      there is a field named GPI1 in the DSTDs, which does get used in some
      cases and ended up turning BUC6 on and off due to the wrong addresses,
      resulting in turning the entire device off (or causing it to reboot).
      
      Removing the hole in the addresses fixes this, fixing one of my
      Bay Trail tablets turning off while booting the mainline kernel.
      
      While at it add comments with the field names used in the DSDTs to
      make it easier to compare the register and bits used at each address
      with the datasheet.

      Pull networking fixes from David Miller:
       "Just a couple more stragglers, I really hope this is it.
      
        1) Don't let frags slip down into the GRO segmentation handlers, from
           Steffen Klassert.
      
        2) Truesize under-estimation triggers warnings in TCP over loopback
           with socket filters, 2 part fix from Eric Dumazet.
      
        3) Fix undesirable reset of bonding MTU to ETH_HLEN on slave removal,
           from Paolo Abeni.
      
        4) If we flush the XFRM policy after garbage collection, it doesn't
           work because stray entries can be created afterwards. Fix from Xin
           Long.
      
        5) Hung socket connection fixes in TIPC from Parthasarathy Bhuvaragan.
      
        6) Fix GRO regression with IPSEC when netfilter is disabled, from
           Sabrina Dubroca.
      
        7) Fix cpsw driver Kconfig dependency regression, from Arnd Bergmann"
