       "The asm-generic tree contains three separate changes for linux-5.19:
      
         - The h8300 architecture is retired after it has been effectively

           we supported that has no MMU implementation, but there are still a
           few architectures (arm, m68k, riscv, sh and xtensa) that support
           CPUs with and without an MMU.
      
         - A series to add a generic ticket spinlock that can be shared by
           most architectures with a working cmpxchg or ll/sc type atomic,
           including the conversion of riscv, csky and openrisc. This series
           is also a prerequisite for the loongarch64 architecture port that
           will come as a separate pull request.

           included from user space without relying on other kernel headers"

      Pull ARMv4T/v5 multiplatform support from Arnd Bergmann:
       "This series has been 12 years in the making, it mostly finishes the
        work that was started with the founding of Linaro to clean up platform
        support in the kernel.
      
        The largest change here is a cleanup of the omap1 platform, which is
        the final ARM machine type to get converted to the common-clk
        subsystem. All the omap1 specific drivers are now made independent of
        the mach/*.h headers to allow the platform to be part of a generic
        ARMv4/v5 multiplatform kernel.
      
        The last bit that enables this support is still missing here while we
        wait for some last dependencies to make it into the mainline kernel
        through other subsystems.
      
        The s3c24xx, ixp4xx, iop32x, ep93xx and dove platforms were all almost
        at the point of allowing multiplatform kernels, this work gets
        completed here along with a few additional cleanup. At the same time,
        the s3c24xx and s3c64xx are now deprecated and expected to get removed
        in the future.
      
        The PXA and OMAP1 bits are in a separate branch because of
        dependencies. Once both branches are merged, only the three Intel
        StrongARM platforms (RiscPC, Footbridge/NetWinder and StrongARM1100)
        need separate kernels, and there are no plans to include these"

       "There are minor updates to SoC specific drivers for chips by Rockchip,
        Samsung, NVIDIA, TI, NXP, i.MX, Qualcomm, and Broadcom.
      
        Noteworthy driver changes include:
      
         - Several conversions of DT bindings to yaml format.
      
         - Renesas adds driver support for R-Car V4H, RZ/V2M and RZ/G2UL SoCs.
      
         - Qualcomm adds a bus driver for the SSC (Snapdragon Sensor Core),
           and support for more chips in the RPMh power domains and the
           soc-id.
      
         - NXP has a new driver for the HDMI blk-ctrl on i.MX8MP.
      
         - Apple M1 gains support for the on-chip NVMe controller, making it
           possible to finally use the internal disks. This also includes SoC
           drivers for their RTKit IPC and for the SART DMA address filter.
      
        For other subsystems that merge their drivers through the SoC tree, we
        have
      
         - Firmware drivers for the ARM firmware stack including TEE, OP-TEE,
           SCMI and FF-A get a number of smaller updates and cleanups. OP-TEE
           now has a cache for firmware argument structures as an
           optimization, and SCMI now supports the 3.1 version of the
           specification.
      
         - Reset controller updates to Amlogic, ASpeed, Renesas and ACPI
           drivers
      
         - Memory controller updates for Tegra, and a few updates for other
           platforms"

       "There are 40 branches this time, adding a lot of new hardware support,
        and cleanups. Krzysztof Kozlowski continues his treewide cleanups.
      
        There are a number of new SoCs, all of them as part of existing
        families, and typically added along with a reference board:
      
         - Renesas RZ/G2UL (R9A07G043) is the single-core version of the
           RZ/G2L general-purpose MPU.
      
         - Renesas RZ/V2M (R9A09G011) is a smart camera SoC

           cores and deep learning accerlation.
      
         - Broadcom BCM47622 is a new broadband SoC based on a quad Cortex-A7
           and dual Wifi-6.
      
         - Corstone1000 is a generic platform from Arm that is used for
           designing custom SoCs, the support for now is for the Fixed Virtual
           Platform emulation for it.
      
         - Mediatek MT8195 (Kompanio 1200) is a high-end consumer chip used in
           upcoming Chromebooks.
      
         - NXP i.MXRT1050 is a Cortex-M7 based microcontroller, the first
           MMU-less SoC to be added in a while
      
        New machines based on already supported SoCs this time are mainly for
        32-bit platforms and include:
      
         - Two wireless routers based on Broadcom bcm4708
      
         - 30 new boards based on NXP i.MX6, i.MX7 and i.MX8 families, mostly

      locking/lockref: Use try_cmpxchg64 in CMPXCHG_LOOP macro · 3378323b
      Uros Bizjak authored
      Use try_cmpxchg64 instead of cmpxchg64 in CMPXCHG_LOOP macro.
      x86 CMPXCHG instruction returns success in ZF flag, so this
      change saves a compare after cmpxchg (and related move instruction
      in front of cmpxchg). The main loop of lockref_get improves from:

      Pull xfs updates from Dave Chinner:
       "This is a big update with lots of new code. The summary below them
        all, so I'll just touch on teh higlights. The two main new features
        are Large Extent Counts and Logged Attribute Replay - these are two
        new foundational features that we are building more complex future
        features on top of.
      
        For upcoming functionality, we need to be able to store hundreds of
        millions of xattrs per inode. The Large Extent Count feature removes
        the limits that prevent this scale of xattr storage, and while we were
        modifying the on disk extent count format we also increased the number
        of data extents we support per inode from 2^32 to 2^47.
      
        We also need to be able to modify xattrs as part of larger atomic
        transactions rather than as standalone transactions. The Logged
        Attribute Replay feature introduces the infrastructure that allows us
        to use intents to record the attribute modifications in the journal
        before we start them, hence allowing other atomic transactions to log
        attribute modification intents and then defer the actual modification
        to later. If we then crash, log recovery then guarantees that the
        attribute is replayed in the context of the atomic transaction that
        logged the intent.
      
        A significant chunk of the commits in this merge are for the base
        attribute replay functionality along with fixes, improvements and
        cleanups related to this new functioanlity. Allison deserves a big
        round of thanks for her ongoing work to get this functionality into
        XFS.
      
        There are also many other smaller changes and improvements, so overall
        this is one of the bigger XFS merge requests in some time.
      
        I will be following up next week with another smaller pull request -
        we already have another round of fixes and improvements to the logged
        attribute replay functionality just about ready to go. They'll soak
        and test over the next week, and I'll send a pull request for them
        near the end of the merge window.
      
        Summary:
      
         - support for printk message indexing.
      
         - large extent counts to provide support for up to 2^47 data extents
           and 2^32 attribute extents, allowing us to scale beyond 4 billion
           data extents to billions of xattrs per inode.
      
         - conversion of various flags fields to be consistently declared as
           unsigned bit fields.
      
         - improvements to realtime extent accounting and converts them to
           per-cpu counters to match all the other block and inode accounting.
      
         - reworks core log formatting code to reduce iterations, have a
           shorter, cleaner fast path and generally be easier to understand
           and maintain.
      
         - improvements to rmap btree searches that reduce overhead by up to
           30% resulting in xfs_scrub runtime reductions of 15%.
      
         - improvements to reflink that remove the size limitations in
           remapping operations and greatly reduce the size of transaction
           reservations.
      
         - reworks the minimum log size calculations to allow us to change
           transaction reservations without changing the minimum supported log
           size.
      
         - removal of quota warning support as it has never been used on
           Linux.
      
         - intent whiteouts to allow us to cancel intents that are completed
           entirely in memory rather than having use CPU and disk bandwidth
           formatting and writing them into the journal when it is not
           necessary. This makes rmap, reflink and extent freeing slightly
           more efficient, but provides massive improvements for....
      
         - Logged Attribute Replay feature support. This is a fundamental
           change to the way we modify attributes, laying the foundation for
           future integration of attribute modifications as part of other
           atomic transactional operations the filesystem performs.
      
         - Lots of cleanups and fixes for the logged attribute replay
           functionality"

      Pull networking updates from Jakub Kicinski:
       "Core
        ----
      
         - Support TCPv6 segmentation offload with super-segments larger than
           64k bytes using the IPv6 Jumbogram extension header (AKA BIG TCP).
      
         - Generalize skb freeing deferral to per-cpu lists, instead of
           per-socket lists.
      
         - Add a netdev statistic for packets dropped due to L2 address
           mismatch (rx_otherhost_dropped).
      
         - Continue work annotating skb drop reasons.
      
         - Accept alternative netdev names (ALT_IFNAME) in more netlink
           requests.
      
         - Add VLAN support for AF_PACKET SOCK_RAW GSO.
      
         - Allow receiving skb mark from the socket as a cmsg.
      
         - Enable memcg accounting for veth queues, sysctl tables and IPv6.
      
        BPF
        ---
      
         - Add libbpf support for User Statically-Defined Tracing (USDTs).
      
         - Speed up symbol resolution for kprobes multi-link attachments.
      
         - Support storing typed pointers to referenced and unreferenced
           objects in BPF maps.
      
         - Add support for BPF link iterator.
      
         - Introduce access to remote CPU map elements in BPF per-cpu map.
      
         - Allow middle-of-the-road settings for the
           kernel.unprivileged_bpf_disabled sysctl.
      
         - Implement basic types of dynamic pointers e.g. to allow for
           dynamically sized ringbuf reservations without extra memory copies.
      
        Protocols
        ---------
      
         - Retire port only listening_hash table, add a second bind table
           hashed by port and address. Avoid linear list walk when binding to
           very popular ports (e.g. 443).
      
         - Add bridge FDB bulk flush filtering support allowing user space to
           remove all FDB entries matching a condition.
      
         - Introduce accept_unsolicited_na sysctl for IPv6 to implement
           router-side changes for RFC9131.
      
         - Support for MPTCP path manager in user space.
      
         - Add MPTCP support for fallback to regular TCP for connections that
           have never connected additional subflows or transmitted
           out-of-sequence data (partial support for RFC8684 fallback).
      
         - Avoid races in MPTCP-level window tracking, stabilize and improve
           throughput.
      
         - Support lockless operation of GRE tunnels with seq numbers enabled.
      
         - WiFi support for host based BSS color collision detection.
      
         - Add support for SO_TXTIME/SCM_TXTIME on CAN sockets.
      
         - Support transmission w/o flow control in CAN ISOTP (ISO 15765-2).
      
         - Support zero-copy Tx with TLS 1.2 crypto offload (sendfile).
      
         - Allow matching on the number of VLAN tags via tc-flower.
      
         - Add tracepoint for tcp_set_ca_state().
      
        Driver API
        ----------
      
         - Improve error reporting from classifier and action offload.
      
         - Add support for listing line cards in switches (devlink).
      
         - Add helpers for reporting page pool statistics with ethtool -S.
      
         - Add support for reading clock cycles when using PTP virtual clocks,
           instead of having the driver convert to time before reporting. This
           makes it possible to report time from different vclocks.
      
         - Support configuring low-latency Tx descriptor push via ethtool.
      
         - Separate Clause 22 and Clause 45 MDIO accesses more explicitly.

      selftests: vm: add the "settings" file with timeout variable · 05987399
      Patrick Wang authored
      The default "timeout" for one kselftest is 45 seconds, while some cases in
      run_vmtests.sh require more time.  This will cause testing timeout like:
      
        not ok 4 selftests: vm: run_vmtests.sh # TIMEOUT 45 seconds
      
      Therefore, add the "settings" file with timeout variable so users can set
      the "timeout" value.

      selftests: vm: check numa_available() before operating "merge_across_nodes" in ksm_tests · 9aa1af95
      Patrick Wang authored
      Patch series "selftests: vm: a few fixup patches".
      
      This series contains three fixup patches for vm selftests.  They are
      independent.  Please see the patches.
      
      
      This patch (of 3):
      
      Currently, ksm_tests operates "merge_across_nodes" with NUMA either
      enabled or disabled.  In a system with NUMA disabled, these operations
      will fail and output a misleading report given "merge_across_nodes" does
      not exist in sysfs:
      
        ----------------------------
        running ./ksm_tests -M -p 10
        ----------------------------
        f /sys/kernel/mm/ksm/merge_across_nodes
        fopen: No such file or directory
        Cannot save default tunables
        [FAIL]
        ----------------------
      
      So check numa_available() before those operations to skip them if NUMA is
      disabled.

      selftests: vm: add process_mrelease tests · 33776141
      Suren Baghdasaryan authored
      Introduce process_mrelease syscall sanity tests which include tests
      which expect to fail:
      
      - process_mrelease with invalid pidfd and flags inputs
      - process_mrelease on a live process with no pending signals
      
      and valid process_mrelease usage which is expected to succeed.  Because
      process_mrelease has to be used against a process with a pending SIGKILL,
      it's possible that the process exits before process_mrelease gets called. 
      In such cases we retry the test with a victim that allocates twice more
      memory up to 1GB.  This would require the victim process to spend more
      time during exit and process_mrelease has a better chance of catching the
      process before it exits and succeeding.
      
      On success the test reports the amount of memory the child had to allocate
      for reaping to succeed.  Sample output:
      
      $ mrelease_test
      Success reaping a child with 1MB of memory allocations
      
      On failure the test reports the failure. Sample outputs:
      
      $ mrelease_test
      All process_mrelease attempts failed!
      
      $ mrelease_test
      process_mrelease: Invalid argument

      Revert "mm/vmscan: never demote for memcg reclaim" · 3f1509c5
      Johannes Weiner authored
      This reverts commit 3a235693.
      
      Its premise was that cgroup reclaim cares about freeing memory inside the
      cgroup, and demotion just moves them around within the cgroup limit. 
      Hence, pages from toptier nodes should be reclaimed directly.
      
      However, with NUMA balancing now doing tier promotions, demotion is part
      of the page aging process.  Global reclaim demotes the coldest toptier
      pages to secondary memory, where their life continues and from which they
      have a chance to get promoted back.  Essentially, tiered memory systems
      have an LRU order that spans multiple nodes.
      
      When cgroup reclaims pages coming off the toptier directly, there can be
      colder pages on lower tier nodes that were demoted by global reclaim. 
      This is an aging inversion, not unlike if cgroups were to reclaim directly
      from the active lists while there are inactive pages.
      
      Proactive reclaim is another factor.  The goal of that it is to offload
      colder pages from expensive RAM to cheaper storage.  When lower tier
      memory is available as an intermediate layer, we want offloading to take
      advantage of it instead of bypassing to storage.
      
      Revert the patch so that cgroups respect the LRU order spanning the memory
      hierarchy.
      
      Of note is a specific undercommit scenario, where all cgroup limits in the
      system add up to <= available toptier memory.  In that case, shuffling
      pages out to lower tiers first to reclaim them from there is inefficient. 
      This is something could be optimized/short-circuited later on (although
      care must be taken not to accidentally recreate the aging inversion). 
      Let's ensure correctness first.
