2f91ff27b0 sound fixes for 6.12-rc2 
Slightly high amount of changes in this round, partly because of my
 vacation in the last weeks.  But all changes are small and nothing
 looks worrisome.
 
 The biggest LOCs is MAINTAINERS updates, and there is a core change
 for card-ID string creation for non-ASCII inputs.  Others are rather
 device-specific, such as new quirks and device IDs for ASoC, usual
 HD-audio and USB-audio quirks and fixes, as well as regression fixes
 in HD-audio HDMI audio and Conexant codec.

64a1d71661 KVM: arm64: Another reviewer reshuffle 
It has been a while since James had any significant bandwidth to
review KVM/arm64 patches. But in the meantime, Joey has stepped up
and did a really good job reviewing some terrifying patch series.

Having talked with the interested parties, it appears that James
is unlikely to have time for KVM in the near future, and that Joey
is willing to take more responsibilities.

So let's appoint Joey as an official reviewer, and give James some
breathing space, as well as my personal thanks. I'm sure he will
be back one way or another!

6f81a446f8 Modules changes for v6.12-rc1 
There are a few fixes / cleanups from Vincent, Chunhui, and Petr, but the
 most important part of this pull request is the Rust community stepping
 up to help maintain both C / Rust code for future Rust module support. We
 grow the set of modules maintainers by 3 now, and with this hope to scale to
 help address what's needed to properly support future Rust module support.
 
 A lot of exciting stuff coming in future kernel releases.
 
 This has been on linux-next for ~ 3 weeks now with no issues.

5e5466433d Char/Misc and other driver changes for 6.12-rc1 
Here is the "big" set of char/misc and other driver subsystem changes
 for 6.12-rc1.  Sorry for the delay, conference travel for the past two
 weeks has this and my other pull requests showing up real late
 in the cycle.
 
 Lots of changes in here, primarily dominated by the usual IIO driver
 updates and additions, but there are also small driver subsystem updates
 all over the place.  Included in here are:
   - lots and lots of new IIO drivers and updates to existing ones
   - interconnect subsystem updates and new drivers
   - nvmem subsystem updates and new drivers
   - mhi driver updates
   - power supply subsystem updates
   - kobj_type const work for many different small subsystems
   - comedi driver fix
   - coresight subsystem and driver updates
   - fpga subsystem improvements
   - slimbus fixups
   - binder new feature addition for "frozen" notifications
   - lots and lots of other small driver updates and cleanups
 
 All of these have been in linux-next for a long time with no reported
 problems.

5701725692 Rust changes for v6.12 
Toolchain and infrastructure:
 
  - Support 'MITIGATION_{RETHUNK,RETPOLINE,SLS}' (which cleans up objtool
    warnings), teach objtool about 'noreturn' Rust symbols and mimic
    '___ADDRESSABLE()' for 'module_{init,exit}'. With that, we should be
    objtool-warning-free, so enable it to run for all Rust object files.
 
  - KASAN (no 'SW_TAGS'), KCFI and shadow call sanitizer support.
 
  - Support 'RUSTC_VERSION', including re-config and re-build on change.
 
  - Split helpers file into several files in a folder, to avoid conflicts
    in it. Eventually those files will be moved to the right places with
    the new build system. In addition, remove the need to manually export
    the symbols defined there, reusing existing machinery for that.
 
  - Relax restriction on configurations with Rust + GCC plugins to just
    the RANDSTRUCT plugin.
 
 'kernel' crate:
 
  - New 'list' module: doubly-linked linked list for use with reference
    counted values, which is heavily used by the upcoming Rust Binder.
    This includes 'ListArc' (a wrapper around 'Arc' that is guaranteed
    unique for the given ID), 'AtomicTracker' (tracks whether a 'ListArc'
    exists using an atomic), 'ListLinks' (the prev/next pointers for an
    item in a linked list), 'List' (the linked list itself), 'Iter' (an
    iterator over a 'List'), 'Cursor' (a cursor into a 'List' that allows
    to remove elements), 'ListArcField' (a field exclusively owned by a
    'ListArc'), as well as support for heterogeneous lists.
 
  - New 'rbtree' module: red-black tree abstractions used by the upcoming
    Rust Binder. This includes 'RBTree' (the red-black tree itself),
    'RBTreeNode' (a node), 'RBTreeNodeReservation' (a memory reservation
    for a node), 'Iter' and 'IterMut' (immutable and mutable iterators),
    'Cursor' (bidirectional cursor that allows to remove elements), as
    well as an entry API similar to the Rust standard library one.
 
  - 'init' module: add 'write_[pin_]init' methods and the 'InPlaceWrite'
    trait. Add the 'assert_pinned!' macro.
 
  - 'sync' module: implement the 'InPlaceInit' trait for 'Arc' by
    introducing an associated type in the trait.
 
  - 'alloc' module: add 'drop_contents' method to 'BoxExt'.
 
  - 'types' module: implement the 'ForeignOwnable' trait for
    'Pin<Box<T>>' and improve the trait's documentation. In addition,
    add the 'into_raw' method to the 'ARef' type.
 
  - 'error' module: in preparation for the upcoming Rust support for
    32-bit architectures, like arm, locally allow Clippy lint for those.
 
 Documentation:
 
  - https://rust.docs.kernel.org has been announced, so link to it.
 
  - Enable rustdoc's "jump to definition" feature, making its output a
    bit closer to the experience in a cross-referencer.
 
  - Debian Testing now also provides recent Rust releases (outside of
    the freeze period), so add it to the list.
 
 MAINTAINERS:
 
  - Trevor is joining as reviewer of the "RUST" entry.
 
 And a few other small bits.

managed pricipally with the net tree, and VIRTIO AND VHOST

usually go with Michael's tree, so let's also put the driver in
the VIRTIO CORE section to have its maintainers in CC for changes
to the virtio-vsock driver.

Merge tag 'pci-v6.12-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci

Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Wait for device readiness after reset by polling Vendor ID and
     looking for Configuration RRS instead of polling the Command
     register and looking for non-error completions, to avoid hardware
     retries done for RRS on non-Vendor ID reads (Bjorn Helgaas)

   - Rename CRS Completion Status to RRS ('Request Retry Status') to
     match PCIe r6.0 spec usage (Bjorn Helgaas)

   - Clear LBMS bit after a manual link retrain so we don't try to
     retrain a link when there's no downstream device anymore (Maciej W.
     Rozycki)

   - Revert to the original link speed after retraining fails instead of
     leaving it restricted to 2.5GT/s, so a future device has a chance
     to use higher speeds (Maciej W. Rozycki)

   - Wait for each level of downstream bus, not just the first, to
     become accessible before restoring devices on that bus (Ilpo
     Järvinen)

   - Add ARCH_PCI_DEV_GROUPS so s390 can add its own attribute_groups
     without having to stomp on the core's pdev->dev.groups (Lukas
     Wunner)

  Driver binding:

   - Export pcim_request_region(), a managed counterpart of
     pci_request_region(), for use by drivers (Philipp Stanner)

   - Export pcim_iomap_region() and deprecate pcim_iomap_regions()
     (Philipp Stanner)

   - Request the PCI BAR used by xboxvideo (Philipp Stanner)

   - Request and map drm/ast BARs with pcim_iomap_region() (Philipp
     Stanner)

  MSI:

   - Add MSI_FLAG_NO_AFFINITY flag for devices that mux MSIs onto a
     single IRQ line and cannot set the affinity of each MSI to a
     specific CPU core (Marek Vasut)

   - Use MSI_FLAG_NO_AFFINITY and remove unnecessary .irq_set_affinity()
     implementations in aardvark, altera, brcmstb, dwc, mediatek-gen3,
     mediatek, mobiveil, plda, rcar, tegra, vmd, xilinx-nwl,
     xilinx-xdma, and xilinx drivers to avoid 'IRQ: set affinity failed'
     warnings (Marek Vasut)

  Power management:

   - Add pwrctl support for ATH11K inside the WCN6855 package (Konrad
     Dybcio)

  PCI device hotplug:

   - Remove unnecessary hpc_ops struct from shpchp (ngn)

   - Check for PCI_POSSIBLE_ERROR(), not 0xffffffff, in cpqphp
     (weiyufeng)

  Virtualization:

   - Mark Creative Labs EMU20k2 INTx masking as broken (Alex Williamson)

   - Add an ACS quirk for Qualcomm SA8775P, which doesn't advertise ACS
     but does provide ACS-like features (Subramanian Ananthanarayanan)

  IOMMU:

   - Add function 0 DMA alias quirk for Glenfly Arise audio function,
     which uses the function 0 Requester ID (WangYuli)

  NPEM:

   - Add Native PCIe Enclosure Management (NPEM) support for sysfs
     control of NVMe RAID storage indicators (ok/fail/locate/
     rebuild/etc) (Mariusz Tkaczyk)

   - Add support for the ACPI _DSM PCIe SSD status LED management, which
     is functionally similar to NPEM but mediated by platform firmware
     (Mariusz Tkaczyk)

  Device trees:

   - Drop minItems and maxItems from ranges in PCI generic host binding
     since host bridges may have several MMIO and I/O port apertures
     (Frank Li)

   - Add kirin, rcar-gen2, uniphier DT binding top-level constraints for
     clocks (Krzysztof Kozlowski)

  Altera PCIe controller driver:

   - Convert altera DT bindings from text to YAML (Matthew Gerlach)

   - Replace TLP_REQ_ID() with macro PCI_DEVID(), which does the same
     thing and is what other drivers use (Jinjie Ruan)

  Broadcom STB PCIe controller driver:

   - Add DT binding maxItems for reset controllers (Jim Quinlan)

   - Use the 'bridge' reset method if described in the DT (Jim Quinlan)

   - Use the 'swinit' reset method if described in the DT (Jim Quinlan)

   - Add 'has_phy' so the existence of a 'rescal' reset controller
     doesn't imply software control of it (Jim Quinlan)

   - Add support for many inbound DMA windows (Jim Quinlan)

   - Rename SoC 'type' to 'soc_base' express the fact that SoCs come in
     families of multiple similar devices (Jim Quinlan)

   - Add Broadcom 7712 DT description and driver support (Jim Quinlan)

   - Sort enums, pcie_offsets[], pcie_cfg_data, .compatible strings for
     maintainability (Bjorn Helgaas)

  Freescale i.MX6 PCIe controller driver:

   - Add imx6q-pcie 'dbi2' and 'atu' reg-names for i.MX8M Endpoints
     (Richard Zhu)

   - Fix a code restructuring error that caused i.MX8MM and i.MX8MP
     Endpoints to fail to establish link (Richard Zhu)

   - Fix i.MX8MP Endpoint occasional failure to trigger MSI by enforcing
     outbound alignment requirement (Richard Zhu)

   - Call phy_power_off() in the .probe() error path (Frank Li)

   - Rename internal names from imx6_* to imx_* since i.MX7/8/9 are also
     supported (Frank Li)

   - Manage Refclk by using SoC-specific callbacks instead of switch
     statements (Frank Li)

   - Manage core reset by using SoC-specific callbacks instead of switch
     statements (Frank Li)

   - Expand comments for erratum ERR010728 workaround (Frank Li)

   - Use generic PHY APIs to configure mode, speed, and submode, which
     is harmless for devices that implement their own internal PHY
     management and don't set the generic imx_pcie->phy (Frank Li)

   - Add i.MX8Q (i.MX8QM, i.MX8QXP, and i.MX8DXL) DT binding and driver
     Root Complex support (Richard Zhu)

  Freescale Layerscape PCIe controller driver:

   - Replace layerscape-pcie DT binding compatible fsl,lx2160a-pcie with
     fsl,lx2160ar2-pcie (Frank Li)

   - Add layerscape-pcie DT binding deprecated 'num-viewport' property
     to address a DT checker warning (Frank Li)

   - Change layerscape-pcie DT binding 'fsl,pcie-scfg' to phandle-array
     (Frank Li)

  Loongson PCIe controller driver:

   - Increase max PCI hosts to 8 for Loongson-3C6000 and newer chipsets
     (Huacai Chen)

  Marvell Aardvark PCIe controller driver:

   - Fix issue with emulating Configuration RRS for two-byte reads of
     Vendor ID; previously it only worked for four-byte reads (Bjorn
     Helgaas)

  MediaTek PCIe Gen3 controller driver:

   - Add per-SoC struct mtk_gen3_pcie_pdata to support multiple SoC
     types (Lorenzo Bianconi)

   - Use reset_bulk APIs to manage PHY reset lines (Lorenzo Bianconi)

   - Add DT and driver support for Airoha EN7581 PCIe controller
     (Lorenzo Bianconi)

  Qualcomm PCIe controller driver:

   - Update qcom,pcie-sc7280 DT binding with eight interrupts (Rayyan
     Ansari)

   - Add back DT 'vddpe-3v3-supply', which was incorrectly removed
     earlier (Johan Hovold)

   - Drop endpoint redundant masking of global IRQ events (Manivannan
     Sadhasivam)

   - Clarify unknown global IRQ message and only log it once to avoid a
     flood (Manivannan Sadhasivam)

   - Add 'linux,pci-domain' property to endpoint DT binding (Manivannan
     Sadhasivam)

   - Assign PCI domain number for endpoint controllers (Manivannan
     Sadhasivam)

7ebf44c910 MAINTAINERS: adjust file entry of the oa_tc6 header 
Commit aa58bec064 ("net: ethernet: oa_tc6: implement register write
operation") adds two new file entries to OPEN ALLIANCE 10BASE-T1S MACPHY
SERIAL INTERFACE FRAMEWORK. One of the two entries mistakenly refers
to drivers/include/linux/oa_tc6.h, whereas the intent is clearly to refer
to include/linux/oa_tc6.h.

Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a
broken reference. Adjust the file entry to the intended location.

88264981f2 sched_ext: Initial pull request for v6.12 
This is the initial pull request of sched_ext. The v7 patchset
 (https://lkml.kernel.org/r/20240618212056.2833381-1-tj@kernel.org) is
 applied on top of tip/sched/core + bpf/master as of Jun 18th.
 
   tip/sched/core 793a62823d1c ("sched/core: Drop spinlocks on contention iff kernel is preempti
 ble")
   bpf/master f6afdaf72a ("Merge branch 'bpf-support-resilient-split-btf'")
 
 Since then, the following pulls were made:
 
 - v6.11-rc1 is pulled to keep up with the mainline.
 
 - tip/sched/core was pulled several times:
 
   - 7b9f6c864a, 0df340ceae, 5ac998574f, 0b1777f0fa: To resolve
     conflicts. See each commit for details on conflicts and their
     resolutions.
 
   - d7b01aef9d: To receive fd03c5b858 ("sched: Rework pick_next_task()")
     and related commits. @prev in added to sched_class->put_prev_task() and
     put_prev_task() is reordered after ->pick_task(), which makes
     sched_class->switch_class() unnecessary. The follow-up commits update
     sched_ext accordingly and drop sched_class->switch_class().
 
 - bpf/master was pulled to receive baebe9aaba ("bpf: allow passing struct
   bpf_iter_<type> as kfunc arguments") and related changes in preparation
   for the DSQ iterator patchset
 
 To obtain the net sched_ext changes, diff against:
 
   git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext.git for-6.12-base
 
 which is the merge of:
 
   tip/sched/core bc9057da1a ("sched/cpufreq: Use NSEC_PER_MSEC for deadline task")
   bpf/master 2ad6d23f46 ("selftests/bpf: Do not update vmlinux.h unnecessarily")
 
 Since the v7 patchset, the following changes were made:
 
 - cpuperf support which was a part of the v6 patchset was posted separately
   and then applied after reviews.
 
 - cgroup support which was a part of the v6 patchset was posted seprately,
   iterated and then applied.
 
 - Improve integration with sched core.
 
 - Double locking usage in migration paths dropped. Depend on
   TASK_ON_RQ_MIGRATING synchronization instead.
 
 - The BPF scheduler couldn't directly dispatch to the local DSQ of another
   CPU using a SCX_DSQ_LOCAL_ON verdict. This caused difficulties around
   handling non-wakeup enqueues. Updated so that SCX_DSQ_LOCAL_ON can be used
   in the enqueue path too.
 
 - DSQ iterator which was a part of the v6 patchset was posted separately.
   The iterator itself was applied after a couple revisions. The associated
   selective consumption kfunc can use further improvements and is still
   being worked on.
 
 - scx_bpf_dispatch[_vtime]_from_dsq() added to increase flexibility. A task
   can now be transferred between two DSQs from almost any context. This
   involved significant refactoring of migration code.
 
 - Various fixes and improvements.
 
 As the branch is based on top of tip/sched/core + bpf/master, please merge
 after both are applied.

Merge tag 'sched_ext-for-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext

Pull sched_ext support from Tejun Heo:
 "This implements a new scheduler class called ‘ext_sched_class’, or
  sched_ext, which allows scheduling policies to be implemented as BPF
  programs.

  The goals of this are:

   - Ease of experimentation and exploration: Enabling rapid iteration
     of new scheduling policies.

   - Customization: Building application-specific schedulers which
     implement policies that are not applicable to general-purpose
     schedulers.

   - Rapid scheduler deployments: Non-disruptive swap outs of scheduling
     policies in production environments"

for the latest series:

Merge tag 'bpf-next-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next

Pull bpf updates from Alexei Starovoitov:

 - Introduce '__attribute__((bpf_fastcall))' for helpers and kfuncs with
   corresponding support in LLVM.

   It is similar to existing 'no_caller_saved_registers' attribute in
   GCC/LLVM with a provision for backward compatibility. It allows
   compilers generate more efficient BPF code assuming the verifier or
   JITs will inline or partially inline a helper/kfunc with such
   attribute. bpf_cast_to_kern_ctx, bpf_rdonly_cast,
   bpf_get_smp_processor_id are the first set of such helpers.

 - Harden and extend ELF build ID parsing logic.

   When called from sleepable context the relevants parts of ELF file
   will be read to find and fetch .note.gnu.build-id information. Also
   harden the logic to avoid TOCTOU, overflow, out-of-bounds problems.

 - Improvements and fixes for sched-ext:
    - Allow passing BPF iterators as kfunc arguments
    - Make the pointer returned from iter_next method trusted
    - Fix x86 JIT convergence issue due to growing/shrinking conditional
      jumps in variable length encoding

 - BPF_LSM related:
    - Introduce few VFS kfuncs and consolidate them in
      fs/bpf_fs_kfuncs.c
    - Enforce correct range of return values from certain LSM hooks
    - Disallow attaching to other LSM hooks

 - Prerequisite work for upcoming Qdisc in BPF:
    - Allow kptrs in program provided structs
    - Support for gen_epilogue in verifier_ops

 - Important fixes:
    - Fix uprobe multi pid filter check
    - Fix bpf_strtol and bpf_strtoul helpers
    - Track equal scalars history on per-instruction level
    - Fix tailcall hierarchy on x86 and arm64
    - Fix signed division overflow to prevent INT_MIN/-1 trap on x86
    - Fix get kernel stack in BPF progs attached to tracepoint:syscall

 - Selftests:
    - Add uprobe bench/stress tool
    - Generate file dependencies to drastically improve re-build time
    - Match JIT-ed and BPF asm with __xlated/__jited keywords
    - Convert older tests to test_progs framework
    - Add support for RISC-V
    - Few fixes when BPF programs are compiled with GCC-BPF backend
      (support for GCC-BPF in BPF CI is ongoing in parallel)
    - Add traffic monitor
    - Enable cross compile and musl libc

617a814f14 ALong with the usual shower of singleton patches, notable patch series in 
this pull request are:
 
 "Align kvrealloc() with krealloc()" from Danilo Krummrich.  Adds
 consistency to the APIs and behaviour of these two core allocation
 functions.  This also simplifies/enables Rustification.
 
 "Some cleanups for shmem" from Baolin Wang.  No functional changes - mode
 code reuse, better function naming, logic simplifications.
 
 "mm: some small page fault cleanups" from Josef Bacik.  No functional
 changes - code cleanups only.
 
 "Various memory tiering fixes" from Zi Yan.  A small fix and a little
 cleanup.
 
 "mm/swap: remove boilerplate" from Yu Zhao.  Code cleanups and
 simplifications and .text shrinkage.
 
 "Kernel stack usage histogram" from Pasha Tatashin and Shakeel Butt.  This
 is a feature, it adds new feilds to /proc/vmstat such as
 
     $ grep kstack /proc/vmstat
     kstack_1k 3
     kstack_2k 188
     kstack_4k 11391
     kstack_8k 243
     kstack_16k 0
 
 which tells us that 11391 processes used 4k of stack while none at all
 used 16k.  Useful for some system tuning things, but partivularly useful
 for "the dynamic kernel stack project".
 
 "kmemleak: support for percpu memory leak detect" from Pavel Tikhomirov.
 Teaches kmemleak to detect leaksage of percpu memory.
 
 "mm: memcg: page counters optimizations" from Roman Gushchin.  "3
 independent small optimizations of page counters".
 
 "mm: split PTE/PMD PT table Kconfig cleanups+clarifications" from David
 Hildenbrand.  Improves PTE/PMD splitlock detection, makes powerpc/8xx work
 correctly by design rather than by accident.
 
 "mm: remove arch_make_page_accessible()" from David Hildenbrand.  Some
 folio conversions which make arch_make_page_accessible() unneeded.
 
 "mm, memcg: cg2 memory{.swap,}.peak write handlers" fro David Finkel.
 Cleans up and fixes our handling of the resetting of the cgroup/process
 peak-memory-use detector.
 
 "Make core VMA operations internal and testable" from Lorenzo Stoakes.
 Rationalizaion and encapsulation of the VMA manipulation APIs.  With a
 view to better enable testing of the VMA functions, even from a
 userspace-only harness.
 
 "mm: zswap: fixes for global shrinker" from Takero Funaki.  Fix issues in
 the zswap global shrinker, resulting in improved performance.
 
 "mm: print the promo watermark in zoneinfo" from Kaiyang Zhao.  Fill in
 some missing info in /proc/zoneinfo.
 
 "mm: replace follow_page() by folio_walk" from David Hildenbrand.  Code
 cleanups and rationalizations (conversion to folio_walk()) resulting in
 the removal of follow_page().
 
 "improving dynamic zswap shrinker protection scheme" from Nhat Pham.  Some
 tuning to improve zswap's dynamic shrinker.  Significant reductions in
 swapin and improvements in performance are shown.
 
 "mm: Fix several issues with unaccepted memory" from Kirill Shutemov.
 Improvements to the new unaccepted memory feature,
 
 "mm/mprotect: Fix dax puds" from Peter Xu.  Implements mprotect on DAX
 PUDs.  This was missing, although nobody seems to have notied yet.
 
 "Introduce a store type enum for the Maple tree" from Sidhartha Kumar.
 Cleanups and modest performance improvements for the maple tree library
 code.
 
 "memcg: further decouple v1 code from v2" from Shakeel Butt.  Move more
 cgroup v1 remnants away from the v2 memcg code.

Merge tag 'mm-stable-2024-09-20-02-31' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Pull MM updates from Andrew Morton:
 "Along with the usual shower of singleton patches, notable patch series
  in this pull request are:

   - "Align kvrealloc() with krealloc()" from Danilo Krummrich. Adds
     consistency to the APIs and behaviour of these two core allocation
     functions. This also simplifies/enables Rustification.

   - "Some cleanups for shmem" from Baolin Wang. No functional changes -
     mode code reuse, better function naming, logic simplifications.

   - "mm: some small page fault cleanups" from Josef Bacik. No
     functional changes - code cleanups only.

   - "Various memory tiering fixes" from Zi Yan. A small fix and a
     little cleanup.

   - "mm/swap: remove boilerplate" from Yu Zhao. Code cleanups and
     simplifications and .text shrinkage.

   - "Kernel stack usage histogram" from Pasha Tatashin and Shakeel
     Butt. This is a feature, it adds new feilds to /proc/vmstat such as

       $ grep kstack /proc/vmstat
       kstack_1k 3
       kstack_2k 188
       kstack_4k 11391
       kstack_8k 243
       kstack_16k 0

     which tells us that 11391 processes used 4k of stack while none at
     all used 16k. Useful for some system tuning things, but
     partivularly useful for "the dynamic kernel stack project".

   - "kmemleak: support for percpu memory leak detect" from Pavel
     Tikhomirov. Teaches kmemleak to detect leaksage of percpu memory.

   - "mm: memcg: page counters optimizations" from Roman Gushchin. "3
     independent small optimizations of page counters".

   - "mm: split PTE/PMD PT table Kconfig cleanups+clarifications" from
     David Hildenbrand. Improves PTE/PMD splitlock detection, makes
     powerpc/8xx work correctly by design rather than by accident.

   - "mm: remove arch_make_page_accessible()" from David Hildenbrand.
     Some folio conversions which make arch_make_page_accessible()
     unneeded.

   - "mm, memcg: cg2 memory{.swap,}.peak write handlers" fro David
     Finkel. Cleans up and fixes our handling of the resetting of the
     cgroup/process peak-memory-use detector.

   - "Make core VMA operations internal and testable" from Lorenzo
     Stoakes. Rationalizaion and encapsulation of the VMA manipulation
     APIs. With a view to better enable testing of the VMA functions,
     even from a userspace-only harness.

   - "mm: zswap: fixes for global shrinker" from Takero Funaki. Fix
     issues in the zswap global shrinker, resulting in improved
     performance.

   - "mm: print the promo watermark in zoneinfo" from Kaiyang Zhao. Fill
     in some missing info in /proc/zoneinfo.

   - "mm: replace follow_page() by folio_walk" from David Hildenbrand.
     Code cleanups and rationalizations (conversion to folio_walk())
     resulting in the removal of follow_page().

   - "improving dynamic zswap shrinker protection scheme" from Nhat
     Pham. Some tuning to improve zswap's dynamic shrinker. Significant
     reductions in swapin and improvements in performance are shown.

   - "mm: Fix several issues with unaccepted memory" from Kirill
     Shutemov. Improvements to the new unaccepted memory feature,

   - "mm/mprotect: Fix dax puds" from Peter Xu. Implements mprotect on
     DAX PUDs. This was missing, although nobody seems to have notied
     yet.

   - "Introduce a store type enum for the Maple tree" from Sidhartha
     Kumar. Cleanups and modest performance improvements for the maple
     tree library code.

   - "memcg: further decouple v1 code from v2" from Shakeel Butt. Move
     more cgroup v1 remnants away from the v2 memcg code.

   - "memcg: initiate deprecation of v1 features" from Shakeel Butt.
     Adds various warnings telling users that memcg v1 features are
     deprecated.

d5e65d1fb7 Hi, 
Just updates and fixes, no major changes.
 
 I might send a PR during the release cycle addressing a performance issue in the
 bus encryption:
 
 1. https://bugzilla.kernel.org/show_bug.cgi?id=219229
 2. https://lore.kernel.org/linux-integrity/20240917154444.702370-1-jarkko@kernel.org/
 
 The first version of the patch set cut out already five seconds and I
 expect similar figures from the current version but I really need some
 more feedback. However, this week is not exactly optimal for getting
 it, given the Vienna conference.
 
 BR, Jarkko

6ff2c29014 MAINTAINERS: make vDSO getrandom matches more generic 
Rather than specifying matches for every architecture, what we actually
want is an extglob-like thing, such as:

F:      **/vdso/*getrandom*

Unfortunately, this isn't possible, but get_maintainers.pl does support
a "N:" directive that uses regexes, so just encode that extglob
statement as an ordinary regex.
