        The fix: way back in the stone age (2003) mode was set to the magic
        number "755" in what is now fs/orangefs/namei.c(orangefs_symlink).
        Łukasz Wrochna reported it and Artur Świgoń sent in a patch to change
        it to octal. Maybe it shouldn't be a magic number at all but rather
        something like "S_IRWXU | S_IRGRP | S_IXGRP | S_IROTH | S_IXOTH"...
      
        cleanup: Colin Ian King found a redundant assignment and sent in a
        patch to remove it"
      
      [ And no, octal numbers for permissions are a lot more legible than a
        binary 'or' of some line noise macros. So 0755 is preferred over
        trying to spell it out using "helpful" macros     - Linus ]

        I'm going to drop those and send the rest (trivial ones + stuff ACKed
        by maintainers) in a separate series - by that point they are
        independent from each other.

      Pull y2038 vfs updates from Arnd Bergmann:
       "Add inode timestamp clamping.
      
        This series from Deepa Dinamani adds a per-superblock minimum/maximum
        timestamp limit for a file system, and clamps timestamps as they are
        written, to avoid random behavior from integer overflow as well as
        having different time stamps on disk vs in memory.
      
        At mount time, a warning is now printed for any file system that can
        represent current timestamps but not future timestamps more than 30
        years into the future, similar to the arbitrary 30 year limit that was
        added to settimeofday().
      
        This was picked as a compromise to warn users to migrate to other file
        systems (e.g. ext4 instead of ext3) when they need the file system to
        survive beyond 2038 (or similar limits in other file systems), but not
        get in the way of normal usage"

      of: restore old handling of cells_name=NULL in of_*_phandle_with_args() · 59e9fcf8
      Uwe Kleine-König authored
      Before commit e42ee610 ("of: Let of_for_each_phandle fallback to
      non-negative cell_count") the iterator functions calling
      of_for_each_phandle assumed a cell count of 0 if cells_name was NULL.
      This corner case was missed when implementing the fallback logic in
      e42ee610 and resulted in an endless loop.
      
      Restore the old behaviour of of_count_phandle_with_args() and
      of_parse_phandle_with_args() and add a check to
      of_phandle_iterator_init() to prevent a similar failure as a safety
      precaution. of_parse_phandle_with_args_map() doesn't need a similar fix
      as cells_name isn't NULL there.

        speedups in the directory entry creation code, some performance
        improvement in the file ACL lookup code, a fix for a logging stall
        during mount, and fixes for concurrency problems.
      
        It has survived a couple of weeks of xfstests runs and merges cleanly.
      
        Summary:
      
         - Remove KM_SLEEP/KM_NOSLEEP.
      
         - Ensure that memory buffers for IO are properly sector-aligned to
           avoid problems that the block layer doesn't check.
      
         - Make the bmap scrubber more efficient in its record checking.
      
         - Don't crash xfs_db when superblock inode geometry is corrupt.
      
         - Fix btree key helper functions.
      
         - Remove unneeded error returns for things that can't fail.
      
         - Fix buffer logging bugs in repair.
      
         - Clean up iterator return values.
      
         - Speed up directory entry creation.
      
         - Enable allocation of xattr value memory buffer during lookup.
      
         - Fix readahead racing with truncate/punch hole.
      
         - Other minor cleanups.
      
         - Fix one AGI/AGF deadlock with RENAME_WHITEOUT.
      
         - More BUG -> WARN whackamole.
      
         - Fix various problems with the log failing to advance under certain
           circumstances, which results in stalls during mount"

       "This continues with work on code refactoring, sanity checks and space
        handling. There are some less user visible changes, nothing that would
        particularly stand out.
      
        User visible changes:
         - tree checker, more sanity checks of:
             - ROOT_ITEM (key, size, generation, level, alignment, flags)
             - EXTENT_ITEM and METADATA_ITEM checks (key, size, offset,
               alignment, refs)
             - tree block reference items
             - EXTENT_DATA_REF (key, hash, offset)
      
         - deprecate flag BTRFS_SUBVOL_CREATE_ASYNC for subvolume creation
           ioctl, scheduled removal in 5.7
      
         - delete stale and unused UAPI definitions
           BTRFS_DEV_REPLACE_ITEM_STATE_*
      
         - improved export of debugging information available via existing
           sysfs directory structure
      
         - try harder to delete relations between qgroups and allow to delete
           orphan entries
      
         - remove unreliable space checks before relocation starts
      
        Core:
         - space handling:
             - improved ticket reservations and other high level logic in
               order to remove special cases
             - factor flushing infrastructure and use it for different
               contexts, allows to remove some special case handling
             - reduce metadata reservation when only updating inodes
             - reduce global block reserve minimum size (affects small
               filesystems)
             - improved overcommit logic wrt global block reserve
      
         - tests:
             - fix memory leaks in extent IO tree
             - catch all TRIM range
      
        Fixes:
         - fix ENOSPC errors, leading to transaction aborts, when cloning
           extents
      
         - several fixes for inode number cache (mount option inode_cache)

         - fix unaligned access to space cache pages with SLUB debug on
           (PowerPC)
      
        Other:

      Pull fs-verity support from Eric Biggers:
       "fs-verity is a filesystem feature that provides Merkle tree based
        hashing (similar to dm-verity) for individual readonly files, mainly
        for the purpose of efficient authenticity verification.
      
        This pull request includes:
      
         (a) The fs/verity/ support layer and documentation.
      
         (b) fs-verity support for ext4 and f2fs.
      
        Compared to the original fs-verity patchset from last year, the UAPI
        to enable fs-verity on a file has been greatly simplified. Lots of
        other things were cleaned up too.
      
        fs-verity is planned to be used by two different projects on Android;
        most of the userspace code is in place already. Another userspace tool
        ("fsverity-utils"), and xfstests, are also available. e2fsprogs and
        f2fs-tools already have fs-verity support. Other people have shown
        interest in using fs-verity too.
      
        I've tested this on ext4 and f2fs with xfstests, both the existing
        tests and the new fs-verity tests. This has also been in linux-next
        since July 30 with no reported issues except a couple minor ones I
        found myself and folded in fixes for.
      
        Ted and I will be co-maintaining fs-verity"

      Pull fscrypt updates from Eric Biggers:
       "This is a large update to fs/crypto/ which includes:
      
         - Add ioctls that add/remove encryption keys to/from a
           filesystem-level keyring.
      
           These fix user-reported issues where e.g. an encrypted home
           directory can break NetworkManager, sshd, Docker, etc. because they
           don't get access to the needed keyring. These ioctls also provide a
           way to lock encrypted directories that doesn't use the
           vm.drop_caches sysctl, so is faster, more reliable, and doesn't
           always need root.
      
         - Add a new encryption policy version ("v2") which switches to a more
           standard, secure, and flexible key derivation function, and starts
           verifying that the correct key was supplied before using it.
      
           The key derivation improvement is needed for its own sake as well
           as for ongoing feature work for which the current way is too
           inflexible.
      
        Work is in progress to update both Android and the 'fscrypt' userspace
        tool to use both these features. (Working patches are available and
        just need to be reviewed+merged.) Chrome OS will likely use them too.
      
        This has also been tested on ext4, f2fs, and ubifs with xfstests --
        both the existing encryption tests, and the new tests for this. This
        has also been in linux-next since Aug 16 with no reported issues. I'm
        also using an fscrypt v2-encrypted home directory on my personal

        Other than that, lots of little things. The usual gadget and xhci and

      Pull driver core updates from Greg Kroah-Hartman:
       "Here is the big driver core update for 5.4-rc1.
      
        There was a bit of a churn in here, with a number of core and OF
        platform patches being added to the tree, and then after much
        discussion and review and a day-long in-person meeting, they were
        decided to be reverted and a new set of patches is currently being
        reviewed on the mailing list.
      
        Other than that churn, there are two "persistent" branches in here
        that other trees will be pulling in as well during the merge window.
        One branch to add support for drivers to have the driver core
        automatically add sysfs attribute files when a driver is bound to a
        device so that the driver doesn't have to manually do it (and then
        clean it up, as it always gets it wrong).
      
        There's another branch in here for generic lookup helpers for the
        driver core that lots of busses are starting to use. That's the
        majority of the non-driver-core changes in this patch series.
      
        There's also some on-going debugfs file creation cleanup that has been
        slowly happening over the past few releases, with the goal to
        hopefully get that done sometime next year.
      
        All of these have been in linux-next for a while now with no reported
        issues"
      
      [ Note that the above-mentioned generic lookup helpers branch was
        already brought in by the LED merge (commit 4feaab05) that had
        shared it.
      
        Also note that that common branch introduced an i2c bug due to a bad
        conversion, which got fixed here. - Linus ]

      The first/last indexes are typically shared with a user app.
      The app can change the 'last' index that the kernel uses
      to store the next result.  This change sanity checks the index
      before using it for writing to a potentially arbitrary address.
      
      This fixes CVE-2019-14821.

      Pull power management updates from Rafael Wysocki:
       "These include a rework of the main suspend-to-idle code flow (related
        to the handling of spurious wakeups), a switch over of several users
        of cpufreq notifiers to QoS-based limits, a new devfreq driver for
        Tegra20, a new cpuidle driver and governor for virtualized guests, an
        extension of the wakeup sources framework to expose wakeup sources as
        device objects in sysfs, and more.
      
        Specifics:
      
         - Rework the main suspend-to-idle control flow to avoid repeating
           "noirq" device resume and suspend operations in case of spurious
           wakeups from the ACPI EC and decouple the ACPI EC wakeups support
           from the LPS0 _DSM support (Rafael Wysocki).
      
         - Extend the wakeup sources framework to expose wakeup sources as
           device objects in sysfs (Tri Vo, Stephen Boyd).
      
         - Expose system suspend statistics in sysfs (Kalesh Singh).
      
         - Introduce a new haltpoll cpuidle driver and a new matching governor
           for virtualized guests wanting to do guest-side polling in the idle
           loop (Marcelo Tosatti, Joao Martins, Wanpeng Li, Stephen Rothwell).
      
         - Fix the menu and teo cpuidle governors to allow the scheduler tick
           to be stopped if PM QoS is used to limit the CPU idle state exit
           latency in some cases (Rafael Wysocki).
      
         - Increase the resolution of the play_idle() argument to microseconds
           for more fine-grained injection of CPU idle cycles (Daniel
           Lezcano).
      
         - Switch over some users of cpuidle notifiers to the new QoS-based
           frequency limits and drop the CPUFREQ_ADJUST and CPUFREQ_NOTIFY
           policy notifier events (Viresh Kumar).
      
         - Add new cpufreq driver based on nvmem for sun50i (Yangtao Li).
      
         - Add support for MT8183 and MT8516 to the mediatek cpufreq driver
           (Andrew-sh.Cheng, Fabien Parent).
      
         - Add i.MX8MN support to the imx-cpufreq-dt cpufreq driver (Anson
           Huang).
      
         - Add qcs404 to cpufreq-dt-platdev blacklist (Jorge Ramirez-Ortiz).
      
         - Update the qcom cpufreq driver (among other things, to make it
           easier to extend and to use kryo cpufreq for other nvmem-based
           SoCs) and add qcs404 support to it (Niklas Cassel, Douglas
           RAILLARD, Sibi Sankar, Sricharan R).
      
         - Fix assorted issues and make assorted minor improvements in the
           cpufreq code (Colin Ian King, Douglas RAILLARD, Florian Fainelli,
           Gustavo Silva, Hariprasad Kelam).
      
         - Add new devfreq driver for NVidia Tegra20 (Dmitry Osipenko, Arnd
           Bergmann).
      
         - Add new Exynos PPMU events to devfreq events and extend that
           mechanism (Lukasz Luba).
      
         - Fix and clean up the exynos-bus devfreq driver (Kamil Konieczny).
      
         - Improve devfreq documentation and governor code, fix spelling typos
           in devfreq (Ezequiel Garcia, Krzysztof Kozlowski, Leonard Crestez,
           MyungJoo Ham, Gaël PORTAY).
      
         - Add regulators enable and disable to the OPP (operating performance
           points) framework (Kamil Konieczny).
      
         - Update the OPP framework to support multiple opp-suspend properties
           (Anson Huang).
      
         - Fix assorted issues and make assorted minor improvements in the OPP
           code (Niklas Cassel, Viresh Kumar, Yue Hu).
      
         - Clean up the generic power domains (genpd) framework (Ulf Hansson).
      
         - Clean up assorted pieces of power management code and documentation
           (Akinobu Mita, Amit Kucheria, Chuhong Yuan).
      
         - Update the pm-graph tool to version 5.5 including multiple fixes
           and improvements (Todd Brandt).
      
         - Update the cpupower utility (Benjamin Weis, Geert Uytterhoeven,

      Pull LED updates from Jacek Anaszewski:
       "In this cycle we've finally managed to contribute the patch set
        sorting out LED naming issues. Besides that there are many changes
        scattered among various LED class drivers and triggers.
      
        LED naming related improvements:
      
         - add new 'function' and 'color' fwnode properties and deprecate
           'label' property which has been frequently abused for conveying
           vendor specific names that have been available in sysfs anyway
      
         - introduce a set of standard LED_FUNCTION* definitions
      
         - introduce a set of standard LED_COLOR_ID* definitions
      
         - add a new {devm_}led_classdev_register_ext() API with the
           capability of automatic LED name composition basing on the
           properties available in the passed fwnode; the function is
           backwards compatible in a sense that it uses 'label' data, if
           present in the fwnode, for creating LED name
      
         - add tools/leds/get_led_device_info.sh script for retrieving LED
           vendor, product and bus names, if applicable; it also performs
           basic validation of an LED name
      
         - update following drivers and their DT bindings to use the new LED
           registration API:
      
              - leds-an30259a, leds-gpio, leds-as3645a, leds-aat1290, leds-cr0014114,
                leds-lm3601x, leds-lm3692x, leds-lp8860, leds-lt3593, leds-sc27xx-blt
      
        Other LED class improvements:
      
         - replace {devm_}led_classdev_register() macros with inlines
      
         - allow to call led_classdev_unregister() unconditionally
      
         - switch to use fwnode instead of be stuck with OF one
      
        LED triggers improvements:
      
         - led-triggers:
              - fix dereferencing of null pointer
              - fix a memory leak bug
      
         - ledtrig-gpio:
              - GPIO 0 is valid
      
        Drop superseeded apu2/3 support from leds-apu since for apu2+ a newer,
        more complete driver exists, based on a generic driver for the AMD
        SOCs gpio-controller, supporting LEDs as well other devices:
      
         - drop profile field from priv data
      
         - drop iosize field from priv data
      
         - drop enum_apu_led_platform_types
      
         - drop superseeded apu2/3 led support
      
         - add pr_fmt prefix for better log output
      
         - fix error message on probing failure
      
        Other misc fixes and improvements to existing LED class drivers:
      
         - leds-ns2, leds-max77650:
              - add of_node_put() before return
      
         - leds-pwm, leds-is31fl32xx:
              - use struct_size() helper
      
         - leds-lm3697, leds-lm36274, leds-lm3532:
              - switch to use fwnode_property_count_uXX()
      
         - leds-lm3532:
              - fix brightness control for i2c mode
              - change the define for the fs current register
              - fixes for the driver for stability
              - add full scale current configuration
              - dt: Add property for full scale current.
              - avoid potentially unpaired regulator calls
              - move static keyword to the front of declarations
              - fix optional led-max-microamp prop error handling
      
         - leds-max77650:
              - add of_node_put() before return
              - add MODULE_ALIAS()
              - Switch to fwnode property API
      
         - leds-as3645a:
              - fix misuse of strlcpy
      
         - leds-netxbig:
              - add of_node_put() in netxbig_leds_get_of_pdata()
              - remove legacy board-file support
      
         - leds-is31fl319x:
              - simplify getting the adapter of a client
      
         - leds-ti-lmu-common:
              - fix coccinelle issue
              - move static keyword to the front of declaration

              - fix a typo in the name of a constant
      
         - leds-lp5562:

      Pull sound updates from Takashi Iwai:
       "As shown in diffstat and logs, it was again a busy development cycle
        at this time, too. The most significant changes are still on-going
        refactoring / modernization works for ASoC core and drivers, but there
        are lots of other changes as well. Here we go, some highlights below:
      
        ASoC:
      
         - Quite a lot of cleanup / refactoring of ASoC core and APIs; most of
           them are systematic, but also including cleanups and modernization
      
         - A bulk of updates for some ASoC platforms, Freescale, sunxi and
           Intel SST/SOF
      
         - Initial support for Sound Open Firmware on i.MX8
      
         - Removal of deprecated w90x900 and nuc900 drivers
      
         - New support for Cirrus Logic CS47L15 and CS47L92, Freescale i.MX
           7ULP and 8MQ, Meson G12A and NXP UDA1334
      
        USB-audio:
      
         - More validations of descriptor units for hardening against bugs
