      Pull ACPI updates from Rafael Wysocki:
       "These rework the handling of ACPI device objects to use the driver
        core facilities for managing child ones instead of some questionable
        home-grown ways without the requisite locking and reference counting,
        clean up the EC driver, improve suspend-to-idle handling on x86, add
        some systems to the ACPI backlight quirk list, fix some assorted
        issues, clean up code and improve documentation.
      
        Specifics:
      
         - Use facilities provided by the driver core and some additional
           helpers to handle the children of a given ACPI device object in
           multiple places instead of using the children and node list heads
           in struct acpi_device which is error prone (Rafael Wysocki).
      
         - Fix ACPI-related device reference counting issue in the hisi_lpc
           bus driver (Yang Yingliang).
      
         - Drop the children and node list heads that are not needed any more

           _CPC return package formats gracefully (Rafael Wysocki).
      
         - Clean up the ACPI EC driver after previous changes in it (Hans de
           Goede).
      
         - Drop leftover acpi_processor_get_limit_info() declaration (Riwen
           Lu).

         - Annotate more functions in the ACPI CPU idle driver to live in the
           cpuidle section (Guilherme G. Piccoli).
      
         - Fix _EINJ vs "special purpose" EFI memory regions (Dan Williams).

           suspend-to-idle driver for x86 platforms (Shyam Sundar S K).
      
         - Clean up checks related to the ACPI_FADT_LOW_POWER_S0 platform flag
           in the LPIT table driver and the suspend-to-idle driver for x86
           platforms (Rafael Wysocki).
      
         - Print information messages regarding declared LPS0 idle support in
           the platform firmware (Rafael Wysocki).

        transfers for single threaded clients.
      
        Benchmarking has been coming out at about a halving of overhead which
        is clearly visible in system level usage that stresses SPI like some
        CAN and IIO applications, especially with small transfers. Thanks to
        David for taking the time to drill down into this and push the work

      Linus Torvalds 提交于
      Pull ARM boardfile deprecation from Arnd Bergmann:
       "Over the past ten years, new machine support was based on device tree,
        and an initial set of about 400 boards using ATAGS with boardfile for
        booting were grandfathered in, with about half of them either removed
        or converted to DT over time.
      
        Based on the recent mailing list discussion I started, I have now
        turned the findings into a set of patches that marks most board files
        as 'depends on UNUSED_BOARD_FILES', leaving only 38 of the 196 boards.
      
        For the boards that are marked as unused, there are two final chances
        for potential users: The removal is scheduled to take place after the
        longterm stable kernel at the end of 2022, so users can stay on that
        version for another few years, and if anyone still has one of these
        machines and is planning to keep updating kernels beyond that version,
        they can speak up now to have their boards taken off the list again.
      
        Waiting for the LTS release also makes sure that there will be at
        least one longterm kernel that contains the recent multiplatform
        conversion along while still supporting all legacy boards.
      
        The short summary of the current status is:
      
         - The s3c24xx, cns3xxx, iop32x and mv78xx0 platforms have no known
           users and will be removed entirely.
      
         - The mmp and davinci platforms have DT support for the important
           machines and will become DT-only after this.
      
         - s3c64xx, dove, orion5x, and pxa keep some board files to allow
           those to be migrated over to DT more easily, but most board files
           are getting removed now. DT support on these platforms is partially
           working but requires changes to additional drivers for the other
           boards.
      
         - omap1, ep93xx, sa1100, footbridge and rpc have no DT support at the
           moment but have some boards with known users. Removing the board
           files that nobody uses should make it easier to try a DT conversion
           if anyone cares.
      
        There is no explicit timeline what happens with the boards that remain
        after this removal, but I expect to revisit this in the future, and
        with most boards gone, there will be a good time to do a treewide
        review of platform drivers that never gained DT support and have no
        remaining in-tree board files"

       "This adds initial support for two SoC families that have been under
        review for a while. In both cases, the origonal idea was to have a
        minimally functional version, but we ended up leaving out the clk
        drivers that are still under review and will be merged through the
        corresponding subsystem tree.

      Pull ARM DT updates from Arnd Bergmann:
       "As usual, the bulk of the changes for the SoC tree are devicetree file
        updates, and most of these changes are for 64-bit embedded machines.
        As before, there are a ton of style cleanups, and additional hardware
        support for existing machines.
      
        Looking only at the new SoC, the notable additions are:
      
         - A whole family of Broadcom broadband SoCs, both 32-bit and 64-bit:
           BCM63178, BCM63158, BCM4912, BCM6858, BCM6878, BCM6846, BCM63146,
           BCM6856, BCM6855, BCM6756, BCM63148, and BCM6813. Each SoC comes
           with a corresponding reference board.
      
         - The new NXP i.MX93 SoC, the follow-up to the popular i.MX6 and
           i.MX8 embedded SoCs, now using Cortex-A55 cores and the Ethos-U65
           NPU.
      
         - Qualcomm Snapdragon 8cx Gen3 (SC8280XP), the current high end of
           Arm based Laptop SoCs, and its automotive cousin, the SA8540P. The
           SC8280XP is used in the Lenovo Thinkpad X13s laptop that also gets
           added here in addition to the reference boards.
      
         - Allwinner H616, a newer version of the H6 SoC, targeted at
           Set-top-box applications. It comes with dts files for the Orange Pi
           zero2 single-board computer and the X96 Mate set-top-box
      
         - Marvell Prestera 98DX2530 (AlleyCat5), a network switch chip in the
           Armada SoC family based on the Cortex-A55 core.
      
        New machines based on previously supported SoCs include:
      
         - Several new machines on NXP i.MX platforms: multiple Toradex
           Colibri boards using the "Iris" and "Ixora" carriers, DH
           electronics i.MX8M Plus DHCOM and PDK2, TQ-Systems TQMa8MPQL, and
           phytech phyBOARD-Polis-i.MX8MM.
      
         - Google Chameleon v3 FPGA board based on Intel Arria10 and Stratix
           10 Software Virtual platform, both in the SoCFPGA platform.
      
         - Two new wireless devices based on Broadcom SoCs: The Asus GT-AX6000
           Router and the Cisco Meraki MR26 access point
      
         - Improved Chromebook support for both the Mediatek and Qualcomm SoC
           families brought added machines: Acer Chromebook 514 (MT8192), Acer
           Chromebook Spin 513 (MT8195) and a couple of SC7180 based machines
           including the Lenovo IdeaPad Chromebook Duet 3.
      
         - Xiaomi Mi Mix2s, LG G7 and LG V35 are mobile phones based on
           Qualcomm SDM845, while Mi 5s Plus is based on MSM8996.
      
         - Finally, there are a few development board on other chips: PCB8309
           (Microchip lan966x), Radxa Rock Pi S (Rockchips RK3308) DH DRC
           Compact (ST STM32MP1) and Inforce IFC6560 (Qualcomm SDM660)"

       "This was a fairly quiet cycle for the locking subsystem:
      
         - lockdep: Fix a handful of the more complex lockdep_init_map_*()
           primitives that can lose the lock_type & cause false reports. No
           such mishap was observed in the wild.

           NOP patching by making it arch-specific code (used on MIPS only),
           and remove the s390 initial NOP patching that was superfluous"

      Pull scheduler updates from Ingo Molnar:
      "Load-balancing improvements:
      
         - Improve NUMA balancing on AMD Zen systems for affine workloads.
      
         - Improve the handling of reduced-capacity CPUs in load-balancing.
      
         - Energy Model improvements: fix & refine all the energy fairness
           metrics (PELT), and remove the conservative threshold requiring 6%
           energy savings to migrate a task. Doing this improves power
           efficiency for most workloads, and also increases the reliability
           of energy-efficiency scheduling.
      
         - Optimize/tweak select_idle_cpu() to spend (much) less time
           searching for an idle CPU on overloaded systems. There's reports of
           several milliseconds spent there on large systems with large
           workloads ...
      
           [ Since the search logic changed, there might be behavioral side
             effects. ]
      
         - Improve NUMA imbalance behavior. On certain systems with spare
           capacity, initial placement of tasks is non-deterministic, and such
           an artificial placement imbalance can persist for a long time,
           hurting (and sometimes helping) performance.
      
           The fix is to make fork-time task placement consistent with runtime
           NUMA balancing placement.
      
           Note that some performance regressions were reported against this,
           caused by workloads that are not memory bandwith limited, which
           benefit from the artificial locality of the placement bug(s). Mel
           Gorman's conclusion, with which we concur, was that consistency is
           better than random workload benefits from non-deterministic bugs:
      
              "Given there is no crystal ball and it's a tradeoff, I think
               it's better to be consistent and use similar logic at both fork
               time and runtime even if it doesn't have universal benefit."
      
         - Improve core scheduling by fixing a bug in
           sched_core_update_cookie() that caused unnecessary forced idling.
      
         - Improve wakeup-balancing by allowing same-LLC wakeup of idle CPUs
           for newly woken tasks.
      
         - Fix a newidle balancing bug that introduced unnecessary wakeup
           latencies.
      
        ABI improvements/fixes:
      
         - Do not check capabilities and do not issue capability check denial
           messages when a scheduler syscall doesn't require privileges. (Such
           as increasing niceness.)
      
         - Add forced-idle accounting to cgroups too.
      
         - Fix/improve the RSEQ ABI to not just silently accept unknown flags.
           (No existing tooling is known to have learned to rely on the
           previous behavior.)
      
         - Depreciate the (unused) RSEQ_CS_FLAG_NO_RESTART_ON_* flags.
      
        Optimizations:
      
         - Optimize & simplify leaf_cfs_rq_list()
      
         - Micro-optimize set_nr_{and_not,if}_polling() via try_cmpxchg().
      
        Misc fixes & cleanups:
      
         - Fix the RSEQ self-tests on RISC-V and Glibc 2.35 systems.
      
         - Fix a full-NOHZ bug that can in some cases result in the tick not
           being re-enabled when the last SCHED_RT task is gone from a
           runqueue but there's still SCHED_OTHER tasks around.

       "Highlights include a major rework of our kPTI page-table rewriting
        code (which makes it both more maintainable and considerably faster in
        the cases where it is required) as well as significant changes to our
        early boot code to reduce the need for data cache maintenance and
        greatly simplify the KASLR relocation dance.
      
        Summary:
      
         - Remove unused generic cpuidle support (replaced by PSCI version)
      
         - Fix documentation describing the kernel virtual address space
      
         - Handling of some new CPU errata in Arm implementations
      
         - Rework of our exception table code in preparation for handling
           machine checks (i.e. RAS errors) more gracefully
      
         - Switch over to the generic implementation of ioremap()
      
         - Fix lockdep tracking in NMI context
      
         - Instrument our memory barrier macros for KCSAN
      
         - Rework of the kPTI G->nG page-table repainting so that the MMU
           remains enabled and the boot time is no longer slowed to a crawl
           for systems which require the late remapping
      
         - Enable support for direct swapping of 2MiB transparent huge-pages
           on systems without MTE
      
         - Fix handling of MTE tags with allocating new pages with HW KASAN
      
         - Expose the SMIDR register to userspace via sysfs
      
         - Continued rework of the stack unwinder, particularly improving the

         - More repainting of our system register definitions to match the
           architectural terminology
      
         - Improvements to the layout of the vDSO objects
      
         - Support for allocating additional bits of HWCAP2 and exposing
           FEAT_EBF16 to userspace on CPUs that support it
      
         - Considerable rework and optimisation of our early boot code to
           reduce the need for cache maintenance and avoid jumping in and out
           of the kernel when handling relocation under KASLR

      Pull acl updates from Christian Brauner:
       "Last cycle we introduced support for mounting overlayfs on top of
        idmapped mounts. While looking into additional testing we realized
        that posix acls don't really work correctly with stacking filesystems
        on top of idmapped layers.
      
        We already knew what the fix were but it would require work that is
        more suitable for the merge window so we turned off posix acls for
        v5.19 for overlayfs on top of idmapped layers with Miklos routing my
        patch upstream in 72a8e05d ("Merge tag 'ovl-fixes-5.19-rc7' [..]").
      
        This contains the work to support posix acls for overlayfs on top of
        idmapped layers. Since the posix acl fixes should use the new
        vfs{g,u}id_t work the associated branch has been merged in. (We sent a
        pull request for this earlier.)
      
        We've also pulled in Miklos pull request containing my patch to turn
        of posix acls on top of idmapped layers. This allowed us to avoid
        rebasing the branch which we didn't like because we were already at
        rc7 by then. Merging it in allows this branch to first fix posix acls
        and then to cleanly revert the temporary fix it brought in by commit
        4a47c638 ("ovl: turn of SB_POSIXACL with idmapped layers
        temporarily").
      
        The last patch in this series adds Seth Forshee as a co-maintainer for
        idmapped mounts. Seth has been integral to all of this work and is
        also the main architect behind the filesystem idmapping work which
        ultimately made filesystems such as FUSE and overlayfs available in
        containers. He continues to be active in both development and review.
        I'm very happy he decided to help and he has my full trust. This
        increases the bus factor which is always great for work like this. I'm
        honestly very excited about this because I think in general we don't
        do great in the bringing on new maintainers department"

      Linus Torvalds 提交于
      Pull fs idmapping updates from Christian Brauner:
       "This introduces the new vfs{g,u}id_t types we agreed on. Similar to
        k{g,u}id_t the new types are just simple wrapper structs around
        regular {g,u}id_t types.
      
        They allow to establish a type safety boundary in the VFS for idmapped
        mounts preventing confusion betwen {g,u}ids mapped into an idmapped
        mount and {g,u}ids mapped into the caller's or the filesystem's
        idmapping.
      
        An initial set of helpers is introduced that allows to operate on
        vfs{g,u}id_t types. We will remove all references to non-type safe
        idmapped mounts helpers in the very near future. The patches do
        already exist.
      
        This converts the core attribute changing codepaths which become
        significantly easier to reason about because of this change.
      
        Just a few highlights here as the patches give detailed overviews of
        what is happening in the commit messages:
      
         - The kernel internal struct iattr contains type safe vfs{g,u}id_t
           values clearly communicating that these values have to take a given
           mount's idmapping into account.
      
         - The ownership values placed in struct iattr to change ownership are
           identical for idmapped and non-idmapped mounts going forward. This
           also allows to simplify stacking filesystems such as overlayfs that
           change attributes In other words, they always represent the values.
      
         - Instead of open coding checks for whether ownership changes have
           been requested and an actual update of the inode is required we now
           have small static inline wrappers that abstract this logic away
           removing a lot of code duplication from individual filesystems that
           all open-coded the same checks"

       - Delay the cleanup of interrupted posix lock requests until the user

       - Tracepoint improvements, e.g. adding the lock resource name.
      
       - Delay the completion of lockspace creation until one full recovery
         cycle has completed. This allows more error cases to be returned to
         the caller.
      
       - Remove warnings from the locking layer about delayed network replies.
         The recently added midcomms warnings are much more useful.
      
       - Begin the process of deprecating two unused lock-timeout-related
         features. These features now require enabling via a Kconfig option,
         and enabling them triggers deprecation warnings. We expect to remove

      Alexander Aring 提交于
      The unhold_lkb() function decrements the lock's kref, and
      asserts that the ref count was not the final one.  Use the
      kref_put release function (which should not be called) to
      call the assert, rather than doing the assert based on the
      kref_put return value.  Using kill_lkb() as the release
      function doesn't make sense if we only want to assert.

      fs: dlm: add deprecation Kconfig and warnings for timeouts · 81eeb82f
      Alexander Aring 提交于
      This patch adds a CONFIG_DLM_DEPRECATED_API Kconfig option
      that must be enabled to use two timeout-related features
      that we intend to remove in kernel v6.2.  Warnings are
      printed if either is enabled and used.  Neither has ever
      been used as far as we know.
      
      . The DLM_LSFL_TIMEWARN lockspace creation flag will be
        removed, along with the associated configfs entry for
        setting the timeout.  Setting the flag and configfs file
        would cause dlm to track how long locks were waiting
        for reply messages.  After a timeout, a kernel message
        would be logged, and a netlink message would be sent
        to userspace.  Recently, midcomms messages have been
        added that produce much better logging about actual
        problems with messages.  No use has ever been found
        for the netlink messages.
      
      . The userspace libdlm API has allowed the DLM_LKF_TIMEOUT
        flag with a timeout value to be set in lock requests.
        The lock request would be cancelled after the timeout.
