      Pull MM updates from Andrew Morton:
      
       - Nick Piggin's "shoot lazy tlbs" series, to improve the peformance of
         switching from a user process to a kernel thread.
      
       - More folio conversions from Kefeng Wang, Zhang Peng and Pankaj
         Raghav.
      
       - zsmalloc performance improvements from Sergey Senozhatsky.
      
       - Yue Zhao has found and fixed some data race issues around the
         alteration of memcg userspace tunables.
      
       - VFS rationalizations from Christoph Hellwig:
           - removal of most of the callers of write_one_page()
           - make __filemap_get_folio()'s return value more useful
      
       - Luis Chamberlain has changed tmpfs so it no longer requires swap
         backing. Use `mount -o noswap'.
      
       - Qi Zheng has made the slab shrinkers operate locklessly, providing
         some scalability benefits.
      
       - Keith Busch has improved dmapool's performance, making part of its
         operations O(1) rather than O(n).
      
       - Peter Xu adds the UFFD_FEATURE_WP_UNPOPULATED feature to userfaultd,
         permitting userspace to wr-protect anon memory unpopulated ptes.
      
       - Kirill Shutemov has changed MAX_ORDER's meaning to be inclusive
         rather than exclusive, and has fixed a bunch of errors which were
         caused by its unintuitive meaning.
      
       - Axel Rasmussen give userfaultfd the UFFDIO_CONTINUE_MODE_WP feature,
         which causes minor faults to install a write-protected pte.
      
       - Vlastimil Babka has done some maintenance work on vma_merge():
         cleanups to the kernel code and improvements to our userspace test
         harness.
      
       - Cleanups to do_fault_around() by Lorenzo Stoakes.
      
       - Mike Rapoport has moved a lot of initialization code out of various
         mm/ files and into mm/mm_init.c.
      
       - Lorenzo Stoakes removd vmf_insert_mixed_prot(), which was added for
         DRM, but DRM doesn't use it any more.
      
       - Lorenzo has also coverted read_kcore() and vread() to use iterators
         and has thereby removed the use of bounce buffers in some cases.
      
       - Lorenzo has also contributed further cleanups of vma_merge().
      
       - Chaitanya Prakash provides some fixes to the mmap selftesting code.
      
       - Matthew Wilcox changes xfs and afs so they no longer take sleeping
         locks in ->map_page(), a step towards RCUification of pagefaults.
      
       - Suren Baghdasaryan has improved mmap_lock scalability by switching to
         per-VMA locking.
      
       - Frederic Weisbecker has reworked the percpu cache draining so that it
         no longer causes latency glitches on cpu isolated workloads.

         logic.
      
       - Liu Shixin has changed zswap's initialization so we no longer waste a
         chunk of memory if zswap is not being used.
      
       - Yosry Ahmed has improved the performance of memcg statistics
         flushing.

       - Pankaj Raghav has made page_endio() unneeded and has removed it.
      
       - Peter Xu contributed some rationalizations of the userfaultfd
         selftests.

         accounting.
      
       - Chaitanya Prakash has fixed some arm-related issues in the
         selftests/mm code.
      
       - Longlong Xia has improved the way in which KSM handles hwpoisoned
         pages.

        discovered while I was reviewing a patch to switch the code to the
        bitmap API by Christophe Jaillet.
      
        So this contains both a fix for the original bug in the Storage Queue
        code that can be backported later as well as the Christophe's patch to
        swich the code to the bitmap API.
      
        Summary:
      
         - Use generic GCC library routines

        soaking on linux-next since v6.3-rc3.
      
        I've slowed down the kernel/sysctl.c moves due to Matthew Wilcox's
        feedback that we should see if we could *save* memory with these moves
        instead of incurring more memory. We currently incur more memory since
        when we move a syctl from kernel/sysclt.c out to its own file we end
        up having to add a new empty sysctl used to register it. To achieve
        saving memory we want to allow syctls to be passed without requiring
        the end element being empty, and just have our registration process
        rely on ARRAY_SIZE(). Without this, supporting both styles of sysctls
        would make the sysctl registration pretty brittle, hard to read and
        maintain as can be seen from Meng Tang's efforts to do just this [0].
        Fortunately, in order to use ARRAY_SIZE() for all sysctl registrations
        also implies doing the work to deprecate two API calls which use
        recursion in order to support sysctl declarations with subdirectories.
      
        And so during this development cycle quite a bit of effort went into
        this deprecation effort. I've annotated the following two APIs are
        deprecated and in few kernel releases we should be good to remove
        them:
      
         - register_sysctl_table()
         - register_sysctl_paths()
      
        During this merge window we should be able to deprecate and unexport
        register_sysctl_paths(), we can probably do that towards the end of
        this merge window.
      
        Deprecating register_sysctl_table() will take a bit more time but this
        pull request goes with a few example of how to do this.
      
        As it turns out each of the conversions to move away from either of
        these two API calls *also* saves memory. And so long term, all these
        changes *will* prove to have saved a bit of memory on boot.
      
        The way I see it then is if remove a user of one deprecated call, it
        gives us enough savings to move one kernel/sysctl.c out from the
        generic arrays as we end up with about the same amount of bytes.
      
        Since deprecating register_sysctl_table() and register_sysctl_paths()
        does not require maintainer coordination except the final unexport
        you'll see quite a bit of these changes from other pull requests, I've
        just kept the stragglers after rc3"

      Linus Torvalds authored
      Pull module updates from Luis Chamberlain:
       "The summary of the changes for this pull requests is:
      
         - Song Liu's new struct module_memory replacement
      
         - Nick Alcock's MODULE_LICENSE() removal for non-modules
      
         - My cleanups and enhancements to reduce the areas where we vmalloc
           module memory for duplicates, and the respective debug code which
           proves the remaining vmalloc pressure comes from userspace.
      
        Most of the changes have been in linux-next for quite some time except
        the minor fixes I made to check if a module was already loaded prior
        to allocating the final module memory with vmalloc and the respective
        debug code it introduces to help clarify the issue. Although the
        functional change is small it is rather safe as it can only *help*
        reduce vmalloc space for duplicates and is confirmed to fix a bootup
        issue with over 400 CPUs with KASAN enabled. I don't expect stable
        kernels to pick up that fix as the cleanups would have also had to
        have been picked up. Folks on larger CPU systems with modules will
        want to just upgrade if vmalloc space has been an issue on bootup.
      
        Given the size of this request, here's some more elaborate details:
      
        The functional change change in this pull request is the very first
        patch from Song Liu which replaces the 'struct module_layout' with a
        new 'struct module_memory'. The old data structure tried to put
        together all types of supported module memory types in one data
        structure, the new one abstracts the differences in memory types in a
        module to allow each one to provide their own set of details. This
        paves the way in the future so we can deal with them in a cleaner way.
        If you look at changes they also provide a nice cleanup of how we
        handle these different memory areas in a module. This change has been
        in linux-next since before the merge window opened for v6.3 so to
        provide more than a full kernel cycle of testing. It's a good thing as
        quite a bit of fixes have been found for it.
      
        Jason Baron then made dynamic debug a first class citizen module user
        by using module notifier callbacks to allocate / remove module
        specific dynamic debug information.
      
        Nick Alcock has done quite a bit of work cross-tree to remove module
        license tags from things which cannot possibly be module at my request
        so to:
      
         a) help him with his longer term tooling goals which require a
            deterministic evaluation if a piece a symbol code could ever be
            part of a module or not. But quite recently it is has been made
            clear that tooling is not the only one that would benefit.
            Disambiguating symbols also helps efforts such as live patching,
            kprobes and BPF, but for other reasons and R&D on this area is
            active with no clear solution in sight.
      
         b) help us inch closer to the now generally accepted long term goal
            of automating all the MODULE_LICENSE() tags from SPDX license tags
      
        In so far as a) is concerned, although module license tags are a no-op
        for non-modules, tools which would want create a mapping of possible
        modules can only rely on the module license tag after the commit
        8b41fc44 ("kbuild: create modules.builtin without
        Makefile.modbuiltin or tristate.conf").
      
        Nick has been working on this *for years* and AFAICT I was the only
        one to suggest two alternatives to this approach for tooling. The
        complexity in one of my suggested approaches lies in that we'd need a
        possible-obj-m and a could-be-module which would check if the object
        being built is part of any kconfig build which could ever lead to it
        being part of a module, and if so define a new define
        -DPOSSIBLE_MODULE [0].
      
        A more obvious yet theoretical approach I've suggested would be to
        have a tristate in kconfig imply the same new -DPOSSIBLE_MODULE as
        well but that means getting kconfig symbol names mapping to modules
        always, and I don't think that's the case today. I am not aware of
        Nick or anyone exploring either of these options. Quite recently Josh
        Poimboeuf has pointed out that live patching, kprobes and BPF would
        benefit from resolving some part of the disambiguation as well but for
        other reasons. The function granularity KASLR (fgkaslr) patches were
        mentioned but Joe Lawrence has clarified this effort has been dropped
        with no clear solution in sight [1].
      
        In the meantime removing module license tags from code which could
        never be modules is welcomed for both objectives mentioned above. Some
        developers have also welcomed these changes as it has helped clarify
        when a module was never possible and they forgot to clean this up, and
        so you'll see quite a bit of Nick's patches in other pull requests for
        this merge window. I just picked up the stragglers after rc3. LWN has
        good coverage on the motivation behind this work [2] and the typical
        cross-tree issues he ran into along the way. The only concrete blocker
        issue he ran into was that we should not remove the MODULE_LICENSE()
        tags from files which have no SPDX tags yet, even if they can never be
        modules. Nick ended up giving up on his efforts due to having to do
        this vetting and backlash he ran into from folks who really did *not
        understand* the core of the issue nor were providing any alternative /
        guidance. I've gone through his changes and dropped the patches which
        dropped the module license tags where an SPDX license tag was missing,
        it only consisted of 11 drivers. To see if a pull request deals with a
        file which lacks SPDX tags you can just use:
      
          ./scripts/spdxcheck.py -f \
      	$(git diff --name-only commid-id | xargs echo)
      
        You'll see a core module file in this pull request for the above, but
        that's not related to his changes. WE just need to add the SPDX
        license tag for the kernel/module/kmod.c file in the future but it
        demonstrates the effectiveness of the script.
      
        Most of Nick's changes were spread out through different trees, and I
        just picked up the slack after rc3 for the last kernel was out. Those
        changes have been in linux-next for over two weeks.
      
        The cleanups, debug code I added and final fix I added for modules
        were motivated by David Hildenbrand's report of boot failing on a
        systems with over 400 CPUs when KASAN was enabled due to running out
        of virtual memory space. Although the functional change only consists
        of 3 lines in the patch "module: avoid allocation if module is already
        present and ready", proving that this was the best we can do on the
        modules side took quite a bit of effort and new debug code.
      
        The initial cleanups I did on the modules side of things has been in
        linux-next since around rc3 of the last kernel, the actual final fix
        for and debug code however have only been in linux-next for about a
        week or so but I think it is worth getting that code in for this merge
        window as it does help fix / prove / evaluate the issues reported with
        larger number of CPUs. Userspace is not yet fixed as it is taking a
        bit of time for folks to understand the crux of the issue and find a
        proper resolution. Worst come to worst, I have a kludge-of-concept [3]
        of how to make kernel_read*() calls for modules unique / converge
        them, but I'm currently inclined to just see if userspace can fix this
        instead"

      cdx: fix build failure due to sysfs 'bus_type' argument needing to be const · d06f5a3f
      Linus Torvalds authored
      Commit 75cff725 ("driver core: bus: mark the struct bus_type for
      sysfs callbacks as constant") missed at least one case - the CDX bus
      driver.  Probably because Greg didn't notice the build failure, because
      it only ends up being enabled on arm64.
      
      And I missed it during the merge, because while I do arm64 builds these
      days, I don't do them in between each pull.  So it took a while for me
      to notice the breakage, rather than me just fixing it in the driver core
      merge that brought this failure case in.
      
      Maybe we should remove the CDX_BUS dependency on arm64 when COMPILE_TEST
      is on?

      mm,unmap: avoid flushing TLB in batch if PTE is inaccessible · 4d4b6d66
      Huang Ying authored
      0Day/LKP reported a performance regression for commit 7e12beb8
      ("migrate_pages: batch flushing TLB").  In the commit, the TLB flushing
      during page migration is batched.  So, in try_to_migrate_one(),
      ptep_clear_flush() is replaced with set_tlb_ubc_flush_pending().  In
      further investigation, it is found that the TLB flushing can be avoided in
      ptep_clear_flush() if the PTE is inaccessible.  In fact, we can optimize
      in similar way for the batched TLB flushing too to improve the
      performance.
      
      So in this patch, we check pte_accessible() before
      set_tlb_ubc_flush_pending() in try_to_unmap/migrate_one().  Tests show
      that the benchmark score of the anon-cow-rand-mt test case of
      vm-scalability test suite can improve up to 2.1% with the patch on a Intel
      server machine.  The TLB flushing IPI can reduce up to 44.3%.

      Bisection led to ac492b9c; and diff against earlier working linux-next
      suggested that it's probably down to an errant xas_store(), which does not
      belong with the later changes (and nor does the positioning of warnings). 
      The later changes look as if they fix the syzbot issue independently.
      
      Remove most of what's left of 2ce0bdfe: just leave one WARN_ON_ONCE
      (xas_error) after the final xas_store() of the multi-index entry.

      Pull driver core updates from Greg KH:
       "Here is the large set of driver core changes for 6.4-rc1.
      
        Once again, a busy development cycle, with lots of changes happening
        in the driver core in the quest to be able to move "struct bus" and
        "struct class" into read-only memory, a task now complete with these
        changes.
      
        This will make the future rust interactions with the driver core more
        "provably correct" as well as providing more obvious lifetime rules
        for all busses and classes in the kernel.
      
        The changes required for this did touch many individual classes and
        busses as many callbacks were changed to take const * parameters
        instead. All of these changes have been submitted to the various
        subsystem maintainers, giving them plenty of time to review, and most
        of them actually did so.
      
        Other than those changes, included in here are a small set of other
        things:
      
         - kobject logging improvements
      
         - cacheinfo improvements and updates

       "A fairly standard release for SPI with the exception of a change to
        the API for specifying chip selects done in preparation for supporting
        devices with more than one chip select, this required some mechanical
        changes throughout the tree which have been cooking in -next happily
        for a while.
      
        There's also a new API to allow us to support TPM chips on half duplex
        controllers.
      
        Summary:
      
         - Refactoring in preparation for supporting multiple chip selects for
           a single device, needed by some flash devices, which required a
           change in the SPI device API visible throughout the tree
      
         - Support for hardware assisted interaction with SPI TPMs on half
           duplex controllers, implemented on nVidia Tedra210 QuadSPI
      
         - Optimisation for large transfers on fsl-cpm devices
      
         - Cleanups around device property use which fix some sisues with
           fwnode
      
         - Use of both void remove() and devm_platform_.*ioremap_resource()

       "At this time, it's an interesting mixture of changes for both old and
        new stuff. Majority of changes are about ASoC (lots of systematic

        we got the fixes and the enhancements of very old PCI cards, too.
      
        Here are some highlights:
      
        ALSA/ASoC Core:
         - Continued effort of more ASoC core cleanups
         - Minor improvements for XRUN handling in indirect PCM helpers
         - Code refactoring of PCM core code
      
        ASoC:
         - Continued feature and simplification work on SOF, including
           addition of a no-DSP mode for bringup, HDA MLink and extensions to
           the IPC4 protocol
         - Hibernation support for CS35L45
         - More DT binding conversions
         - Support for Cirrus Logic CS35L56, Freescale QMC, Maxim MAX98363,
           nVidia systems with MAX9809x and RT5631, Realtek RT712, Renesas

       - First part of DT header detangling dropping cpu.h from of_device.h
         and replacing some includes with forward declarations. A handful of
         drivers needed some adjustment to their includes as a result.
      
       - Refactor of_device.h to be used by bus drivers rather than various
         device drivers. This moves non-bus related functions out of
         of_device.h. The end goal is for of_platform.h and of_device.h to
         stop including each other.
      
       - Refactor open coded parsing of "ranges" in some bus drivers to use DT
         address parsing functions
      
       - Add some new address parsing functions of_property_read_reg(),
         of_range_count(), and of_range_to_resource() in preparation to
         convert more open coded parsing of DT addresses to use them.
      
       - Treewide clean-ups to use of_property_read_bool() and
         of_property_present() as appropriate. The ones here are the ones that
         didn't get picked up elsewhere.

      Pull iommufd updates from Jason Gunthorpe:
       "Two series:
      
         - Reorganize how the hardware page table objects are managed,
           particularly their destruction flow. Increase the selftest test
           coverage in this area by creating a more complete mock iommu
           driver.
      
           This is preparation to add a replace operation for HWPT binding,
           which is done but waiting for the VFIO parts to complete so there
           is a user.
      
         - Split the iommufd support for "access" to make it two step -
           allocate an access then link it to an IOAS. Update VFIO and have
           VFIO always create an access even for the VFIO mdevs that never do
           DMA.
      
           This is also preperation for the replace VFIO series that will
           allow replace to work on access types as well.
      
        Three minor fixes:
      
         - Sykzaller found the selftest code didn't check for overflow when
           processing user VAs
      
         - smatch noted a .data item should have been static

      mm/mremap: fix vm_pgoff in vma_merge() case 3 · 7e775787
      Vlastimil Babka authored
      After upgrading build guests to v6.3, rpm started segfaulting for
      specific packages, which was bisected to commit 0503ea8f ("mm/mmap:
      remove __vma_adjust()"). rpm is doing many mremap() operations with file
      mappings of its db. The problem is that in vma_merge() case 3 (we merge
      with the next vma, expanding it downwards) vm_pgoff is not adjusted as
      it should when vm_start changes. As a result the rpm process most likely
      sees data from the wrong offset of the file. Fix the vm_pgoff
      calculation.
      
      For case 8 this is a non-functional change as the resulting vm_pgoff is
      the same.

      Linus Torvalds authored
      Pull networking updates from Paolo Abeni:
       "Core:
      
         - Introduce a config option to tweak MAX_SKB_FRAGS. Increasing the
           default value allows for better BIG TCP performances
      
         - Reduce compound page head access for zero-copy data transfers
      
         - RPS/RFS improvements, avoiding unneeded NET_RX_SOFTIRQ when
           possible
      
         - Threaded NAPI improvements, adding defer skb free support and
           unneeded softirq avoidance
      
         - Address dst_entry reference count scalability issues, via false
           sharing avoidance and optimize refcount tracking
      
         - Add lockless accesses annotation to sk_err[_soft]
      
         - Optimize again the skb struct layout
      
         - Extends the skb drop reasons to make it usable by multiple
           subsystems
      
         - Better const qualifier awareness for socket casts
      
        BPF:
      
         - Add skb and XDP typed dynptrs which allow BPF programs for more
           ergonomic and less brittle iteration through data and
           variable-sized accesses
      
         - Add a new BPF netfilter program type and minimal support to hook
           BPF programs to netfilter hooks such as prerouting or forward
      
         - Add more precise memory usage reporting for all BPF map types
      
         - Adds support for using {FOU,GUE} encap with an ipip device
           operating in collect_md mode and add a set of BPF kfuncs for
           controlling encap params
      
         - Allow BPF programs to detect at load time whether a particular
           kfunc exists or not, and also add support for this in light
           skeleton
      
         - Bigger batch of BPF verifier improvements to prepare for upcoming
           BPF open-coded iterators allowing for less restrictive looping
           capabilities
      
         - Rework RCU enforcement in the verifier, add kptr_rcu and enforce
           BPF programs to NULL-check before passing such pointers into kfunc
      
         - Add support for kptrs in percpu hashmaps, percpu LRU hashmaps and
           in local storage maps
      
         - Enable RCU semantics for task BPF kptrs and allow referenced kptr
           tasks to be stored in BPF maps
      
         - Add support for refcounted local kptrs to the verifier for allowing
           shared ownership, useful for adding a node to both the BPF list and
           rbtree
      
         - Add BPF verifier support for ST instructions in
           convert_ctx_access() which will help new -mcpu=v4 clang flag to
           start emitting them
      
         - Add ARM32 USDT support to libbpf
      
         - Improve bpftool's visual program dump which produces the control
           flow graph in a DOT format by adding C source inline annotations
      
        Protocols:
      
         - IPv4: Allow adding to IPv4 address a 'protocol' tag. Such value
           indicates the provenance of the IP address
      
         - IPv6: optimize route lookup, dropping unneeded R/W lock acquisition
      
         - Add the handshake upcall mechanism, allowing the user-space to
           implement generic TLS handshake on kernel's behalf
      
         - Bridge: support per-{Port, VLAN} neighbor suppression, increasing
           resilience to nodes failures
      
         - SCTP: add support for Fair Capacity and Weighted Fair Queueing
           schedulers
      
         - MPTCP: delay first subflow allocation up to its first usage. This
           will allow for later better LSM interaction
      
         - xfrm: Remove inner/outer modes from input/output path. These are
           not needed anymore
      
         - WiFi:
            - reduced neighbor report (RNR) handling for AP mode
            - HW timestamping support
            - support for randomized auth/deauth TA for PASN privacy
            - per-link debugfs for multi-link
            - TC offload support for mac80211 drivers
            - mac80211 mesh fast-xmit and fast-rx support
            - enable Wi-Fi 7 (EHT) mesh support
      
        Netfilter:
      
         - Add nf_tables 'brouting' support, to force a packet to be routed
           instead of being bridged
      
         - Update bridge netfilter and ovs conntrack helpers to handle IPv6
           Jumbo packets properly, i.e. fetch the packet length from
           hop-by-hop extension header. This is needed for BIT TCP support
      
         - The iptables 32bit compat interface isn't compiled in by default
           anymore
      
         - Move ip(6)tables builtin icmp matches to the udptcp one. This has
           the advantage that icmp/icmpv6 match doesn't load the
           iptables/ip6tables modules anymore when iptables-nft is used
      
         - Extended netlink error report for netdevice in flowtables and
           netdev/chains. Allow for incrementally add/delete devices to netdev
           basechain. Allow to create netdev chain without device
      
        Driver API:
      
         - Remove redundant Device Control Error Reporting Enable, as PCI core
           has already error reporting enabled at enumeration time
      
         - Move Multicast DB netlink handlers to core, allowing devices other
           then bridge to use them
      
         - Allow the page_pool to directly recycle the pages from safely
           localized NAPI
      
         - Implement lockless TX queue stop/wake combo macros, allowing for
           further code de-duplication and sanitization
      
         - Add YNL support for user headers and struct attrs
      
         - Add partial YNL specification for devlink
      
         - Add partial YNL specification for ethtool
      
         - Add tc-mqprio and tc-taprio support for preemptible traffic classes
      
         - Add tx push buf len param to ethtool, specifies the maximum number
           of bytes of a transmitted packet a driver can push directly to the
           underlying device
      
         - Add basic LED support for switch/phy
      
         - Add NAPI documentation, stop relaying on external links
      
         - Convert dsa_master_ioctl() to netdev notifier. This is a
           preparatory work to make the hardware timestamping layer selectable
           by user space
      
         - Add transceiver support and improve the error messages for CAN-FD
           controllers
