      Merge branch 'hpe/gxp-soc' into arm/late · 3e111946
      Arnd Bergmann authored
      Patch series from Nick Hawkins:
      
      "The GXP is the HPE BMC SoC that is used in the majority of HPE current
       generation servers. Traditionally the asic will last multiple
       generations of server before being replaced.
      
       Info about SoC:
      
        HPE GXP is the name of the HPE Soc. This SoC is used to implement many
        BMC features at HPE. It supports ARMv7 architecture based on the Cortex
        A9 core. It is capable of using an AXI bus to which a memory controller
        is attached. It has multiple SPI interfaces to connect boot flash and
        BIOS flash. It uses a 10/100/1000 MAC for network connectivity. It has
        multiple i2c engines to drive connectivity with a host infrastructure.
        The initial patches enable the watchdog and timer enabling the host to
        be able to boot."

       "The asm-generic tree contains three separate changes for linux-5.19:
      
         - The h8300 architecture is retired after it has been effectively
           unmaintained for a number of years. This is the last architecture
           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.
      
         - A cleanup of some exported uapi header files to ensure they can be
           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"

         - 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.

      Pull ARM DT updates from Arnd Bergmann:
       "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
      
         - Renesas R-Car V4H (R8A779G0) is an automotive chip with Cortex-A76
           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
           for the industrial embedded market, and on NXP LS1021A based IOT
           board.
      
         - Two ethernet switches based on Microchip LAN966
      
         - Eight Qualcomm Snapdragon based machines, including a smartwatch, a
           Chromebook board and some phones
      
         - Another phone based on the old ST-Ericsson Ux500 platform

      locking/lockref: Use try_cmpxchg64 in CMPXCHG_LOOP macro · 3378323b
      Uros Bizjak authored
      Use try_cmpxchg64 instead of cmpxchg64 in CMPXCHG_LOOP macro.

      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.

      Pull printk updates from Petr Mladek:
      
       - Offload writing printk() messages on consoles to per-console
         kthreads.
      
         It prevents soft-lockups when an extensive amount of messages is
         printed. It was observed, for example, during boot of large systems
         with a lot of peripherals like disks or network interfaces.
      
         It prevents live-lockups that were observed, for example, when
         messages about allocation failures were reported and a CPU handled
         consoles instead of reclaiming the memory. It was hard to solve even
         with rate limiting because it would need to take into account the
         amount of messages and the speed of all consoles.
      
         It is a must to have for real time. Otherwise, any printk() might
         break latency guarantees.
      
         The per-console kthreads allow to handle each console on its own
         speed. Slow consoles do not longer slow down faster ones. And
         printk() does not longer unpredictably slows down various code paths.
      
         There are situations when the kthreads are either not available or
         not reliable, for example, early boot, suspend, or panic. In these
         situations, printk() uses the legacy mode and tries to handle
         consoles immediately.
      
       - Add documentation for the printk index.

      Pull slab updates from Vlastimil Babka:
      
       - Conversion of slub_debug stack traces to stackdepot, allowing more
         useful debugfs-based inspection for e.g. memory leak debugging.
         Allocation and free debugfs info now includes full traces and is
         sorted by the unique trace frequency.
      
         The stackdepot conversion was already attempted last year but
         reverted by ae14c63a. The memory overhead (while not actually
         enabled on boot) has been meanwhile solved by making the large
         stackdepot allocation dynamic. The xfstest issues haven't been
         reproduced on current kernel locally nor in -next, so the slab cache
         layout changes that originally made that bug manifest were probably
         not the root cause.

      linux/types.h: reinstate "__bitwise__" macro for user space use · caa28984
      Linus Torvalds authored
      Commit c724c866 ("linux/types.h: remove unnecessary __bitwise__")
      was right that there are no users of __bitwise__ in the kernel, but it
      turns out there are user space users of it that do expect it.
      
      It is, after all, in the uapi directory, so user space usage is to be
      expected.
      
      Instead of reverting the commit completely, let's just clarify the
      situation so that it doesn't happen again, and have some in-code
      explanations for why that "__bitwise__" still exists.

       "There's a couple of corrections sent in by Andreas for some accounting
        errors.
      
        The biggest change this time around is that writeback errors longer
        clear pageuptodate nor does XFS invalidate the page cache anymore.
        This brings XFS (and gfs2/zonefs) behavior in line with every other
        Linux filesystem driver, and fixes some UAF bugs that only cropped up
        after willy turned on multipage folios for XFS in 5.18-rc1.
      
        Regrettably, it took all the way to the end of the 5.18 cycle to find
        the source of these bugs and reach a consensus that XFS' writeback
        failure behavior from 20 years ago is no longer necessary.
      
        Summary:
      
         - Fix a couple of accounting errors in the buffered io code.
      
         - Discontinue the practice of marking folios !uptodate and
           invalidating them when writeback fails.
      
           This fixes some UAF bugs when multipage folios are enabled, and
           brings the behavior of XFS/gfs/zonefs into alignment with the
           behavior of all the other Linux filesystems"

      Pull erofs (and fscache) updates from Gao Xiang:
       "After working on it on the mailing list for more than half a year, we
        finally form 'erofs over fscache' feature into shape. Hopefully it
        could bring more possibility to the communities.
      
        The story mainly started from a new project what we called "RAFS v6" [1]
        for Nydus image service almost a year ago, which enhances EROFS to be
        a new form of one bootstrap (which includes metadata representing the
        whole fs tree) + several data-deduplicated content addressable blobs
        (actually treated as multiple devices). Each blob can represent one
        container image layer but not quite exactly since all new data can be
        fully existed in the previous blobs so no need to introduce another
        new blob.
      
        It is actually not a new idea (at least on my side it's much like a
        simpilied casync [2] for now) and has many benefits over per-file
        blobs or some other exist ways since typically each RAFS v6 image only
        has dozens of device blobs instead of thousands of per-file blobs.
        It's easy to be signed with user keys as a golden image, transfered
        untouchedly with minimal overhead over the network, kept in some type
        of storage conveniently, and run with (optional) runtime verification
        but without involving too many irrelevant features crossing the system
        beyond EROFS itself. At least it's our final goal and we're keeping
        working on it. There was also a good summary of this approach from the
        casync author [3].
      
        Regardless further optimizations, this work is almost done in the
        previous Linux release cycles. In this round, we'd like to introduce
        on-demand load for EROFS with the fscache/cachefiles infrastructure,
        considering the following advantages:
      
         - Introduce new file-based backend to EROFS. Although each image only
           contains dozens of blobs but in densely-deployed runC host for
           example, there could still be massive blobs on a machine, which is
           messy if each blob is treated as a device. In contrast, fscache and
           cachefiles are really great interfaces for us to make them work.
      
         - Introduce on-demand load to fscache and EROFS. Previously, fscache
           is mainly used to caching network-likewise filesystems, now it can
           support on-demand downloading for local fses too with the exact
           localfs on-disk format. It has many advantages which we're been
           described in the latest patchset cover letter [4]. In addition to
           that, most importantly, the cached data is still stored in the
           original local fs on-disk format so that it's still the one signed
           with private keys but only could be partially available. Users can
           fully trust it during running. Later, users can also back up
           cachefiles easily to another machine.
      
         - More reliable on-demand approach in principle. After data is all
           available locally, user daemon can be no longer online in some use
           cases, which helps daemon crash recovery (filesystems can still in
           service) and hot-upgrade (user daemon can be upgraded more
           frequently due to new features or protocols introduced.)
      
         - Other format can also be converted to EROFS filesystem format over
           the internet on the fly with the new on-demand load feature and
           mounted. That is entirely possible with on-demand load feature as
           long as such archive format metadata can be fetched in advance like
           stargz.
      
        In addition, although currently our target user is Nydus image service [5],
        but laterly, it can be used for other use cases like on-demand system
        booting, etc. As for the fscache on-demand load feature itself,
        strictly it can be used for other local fses too. Laterly we could
        promote most code to the iomap infrastructure and also enhance it in
        the read-write way if other local fses are interested.
      
        Thanks David Howells for taking so much time and patience on this
        these months, many thanks with great respect here again! Thanks Jeffle
        for working on this feature and Xin Yin from Bytedance for
        asynchronous I/O implementation as well as Zichen Tian, Jia Zhu, and
        Yan Song for testing, much appeciated. We're also exploring more
        possibly over fscache cache management over FSDAX for secure
        containers and working on more improvements and useful features for
        fscache, cachefiles, and on-demand load.
      
        In addition to "erofs over fscache", NFS export and idmapped mount are
        also completed in this cycle for container use cases as well.
      
        Summary:
      
         - Add erofs on-demand load support over fscache
      
         - Support NFS export for erofs
      
         - Support idmapped mounts for erofs
