Linus Torvalds 500920fa76 gpio updates for v6.19-rc1 
GPIO core:
 - add proper support for shared GPIOs that's aiming to replace the
   current sharing mechanism (which provides no synchronization ot enable
   counting) and enable it for Qualcomm platforms
 - improve the software node GPIO lookup by using the fwnode
   representation instead of the software node's name which was prone to
   bugs (GPIO controllers don't have to use the software node's name as
   their kernel label)
 - remove the last user of legacy-of-mm-gpiochip.h and drop the header
 - move closer to removing the legacy gpio_request_one() routine
 - rename some symbols for consistency
 - shrink GPIO printk() helpers by reusing existing code
 - remove some redundant kernel messages
 - use min() instead of min_t() in GPIO ACPI code
 - use system_percpu_wq instead of system_wq in GPIO character device code
 
 New drivers:
 - add a driver for the QIXIS FPGA GPIO controller
 
 Driver improvements:
 - use modernized variants of power management macros across a wide array
   of drivers in order to avoid having to use the __maybe_unused attribute
 - convert gpio-elkhartlake and reset-gpio to using the auxiliary bus
   instead of the platform bus as they are not really described in
   firmware
 - use lock guards and update symbol prefixes in gpio-mmio
 - support the bryx radio interface kit in gpio-mpsse + refactor the
   driver
 - use software nodes for configuring the reset-gpio driver, including
   setting up the reference to the shared "reset" pin
 - check and propagate the return value of gpiod_set_value() to user-space
   in gpio-virtuser (this was previously not possible as this function
   returned void)
 - extend the gpio-regmap helper with more features (bypass cache for
   aliased inputs, force writes for aliased data registers, add a new
   configuration parameter)
 - remove unneeded includes from gpio-aspeed and gpio-latch
 - add support for Tegra410 to gpio-tegra186
 - replace PCI-specific PM with generic device-level PM in gpio-bt8xx
 - use dynamic GPIO range allocation in gpio-loongson-64bit
 - improve handling of level-triggered interrupts in gpio-pca953x
 - add suspend/resume support to gpio-fxl6408
 - add support for more models to gpio-menz127
 - optimize gpio-mvebu interrupt handling by avoiding unnecessary calls
   to mvebu_gpio_irq_handler()
 - make locking more consistent in gpio-grgpio
 
 Device-tree bindings:
 - document new NXP and Microchip models
 
 Documentation:
 - add a comprehensive compatibility and feature list for gpio-pca953x,
   which is a great addition as it's probably the most commonly used GPIO
   expander driver
 - kernel-doc tweaks
 
 Late fixes:
 - use BYTE_CTRL_MODE for 2K2000/3000 models in gpio-loongson

Pull gpio updates from Bartosz Golaszewski:
 "There's one new driver, lots of various updates to existing ones, some
  refactoring support for new models and misc tweaks and fixes.

  The biggest new feature in GPIO core is adding support for managed,
  enable-counted sharing of GPIO pins, something that - until now - was
  only hacked around with the GPIOD_FLAGS_BIT_NONEXCLUSIVE request flag
  which basically allowed drivers to "fight it out" for the descriptor
  and provided no synchronization. It was enabled on Qualcomm platforms
  (and thus is enabled on arm64 defconfig) and I plan on removing
  GPIOD_FLAGS_BIT_NONEXCLUSIVE once all drivers using it are switched to
  the new mechanism.

  GPIO core:
   - add proper support for shared GPIOs that's aiming to replace the
     current sharing mechanism (which provides no synchronization ot
     enable counting) and enable it for Qualcomm platforms
   - improve the software node GPIO lookup by using the fwnode

Linus Torvalds 205f1a0d18 firewire updates for v6.19 
This release includes two changes for core functions, which affects all
 use cases of this subsystem.
 
  - Handle per-device interoperability quirks
    It is well known that some devices have quirks affecting
    interoperability. To identify such quirks at an early stages of
    device detection, the step for reading the configuration ROM contents
    has been changed. As a side effect, the entire detection process is
    now performed at the basic transaction speed (S100), without no trial
    to probe higher supported speeds.
    With this change, the following devices should now work with fewer
    issues:
    - TASCAM FW-1884, FW-1804, and FW-1082
    - MOTU Audio Express
 
  - Safer removals of host card
    There was a race condition between host card removal and handling of
    bus reset events in the workqueue. This appears to be a long standing
    issue (for a dozen years or so[1]), and recent changes to use more
    workqueues escalate it. To solve it, a new callback has been added to
    the 1394 OHCI PCI driver to unregister the interrupt sources and wait
    for workqueue completions when removing a card instance.

Linus Torvalds fa5ef10561 spi: Updates for v6.19 
This release is almost entirely new drivers, with a couple of small
 changes in generic code.  The biggest individual update is a rename of
 the existing Microchip driver and the addition of a new driver for the
 silicon SPI controller in their PolarFire SoCs.  The overlap between the
 soft IP supported by the current driver and this new one is regrettably
 all in the IP and not in the register interface offered to software.
 
  - Add a time offset parameter for offloads, allowing them to be defined
    in relation to each other.  This is useful for IIO type applcations
    where you trigger an operation then read the result after a delay.
  - Add a tracepoint for flash exec_ops, bringing the flash support more
    in line with the debuggability of vanilla SPI.
  - Support for Airoha EN7523, Arduino MCUs, Aspeed AST2700, Microchip
    PolarFire SPI controllers, NXP i.MX51 ECSPI target mode, Qualcomm
    IPQ5414 and IPQ5332, Renesas RZ/T2H, RZ/V2N and RZ/2NH and SpacemiT K1
    QuadSPI.
 
 There's also a small set of ASoC cleanups that I mistakenly applied to
 the SPI tree and then put more stuff on top of before it was brought to
 my attention, sorry about that.

Linus Torvalds 0a9431fa74 regulator: Updates for v6.19 
This is a relatively busy release for the regulator API, as well as a
 good collection of new drivers we've got a little bit of core work and a
 bunch of cleanup throughout the subsystem:
 
  - Support for propagating undervoltage events to child regulators.
  - Undo enables done on supplies when setting enabling regulators via
    constraints fails.
  - Pull in some gpiolib changes adding support for shared GPIOs to
    the gpiolib core, using them to replace the open coded variant of this
    that we've had in the regulator API for a long time.
  - Support for Fitipower FP9931 and JD9330, Mediatek MT6316, MT6363 and
    MT6373, NXP PF1550 and Qualcomm PMH01XX and PMCX0102
 
 The PF1550 support was originally going to go via the MFD tree but
 Krzysztof's cleanup work overlapped with it so I pulled in Lee's signed
 tag with support for the device.

  - Support for sparseness information in the flat cache, allowing users
    that really need the performance properties it provides to benefit
    from the interface and startup time improvements that sparsness provides
    without needing to go all the way to a more fancy data structure.

Linus Torvalds edd2b9832d Core MTD changes: 
- We must ignore error -ENOENT from parsers on subpartitions which is a
   legitimate return value.
 
 - PM support is added to the intel-dg driver.
 
 Raw NAND changes:
 
 - The major change in this MR will be the support for the Allwinner H616
   NAND controller, which lead to numerous changes and cleanups in the
   driver.
 
 - Another notable change on this driver is the use of
   field_get()/field_prep(), but since the global support for this
   helpers is going to be merged in the same release as we start using
   these helpers, it implies undefining them in the first place to avoid
   warnings. Depending on the merging order (Yuri's bitmap branch or
   mtd/next), a temporary warning may arise.
 
 - Marvell drivers layout handling changes have also landed, they fix
   previous definitions and abuses that have been made previously, which
   implied to relax the ECC parameters validation in the core a bit.
 
 - The Cadence NAND controller driver gets NV-DDR interface support.
 
 SPI NAND changes:
 
 - Support for FudanMicro FM25S01BI3 and ESMT F50L1G41LC is added.
 
 SPI NOR changes:
 
 - Fix SMPT parsing for S25FS-S flash family. They report variable dummy
   cycles for reads. This results in the default of 0 being used. This
   works for other Infineon chips, but not for the S25FS-S family. They
   need 8 dummy cycles. Add fixup hooks to specify that. Also add fixup
   hooks to fix incorrect map ID data in SFDP.
 
 - Add support for a bunch of Winbond flashes. Their block protection
   information is not discoverable, so they need to have an entry in the
   flash tables to describe that.
 
 - Some cleanups for Micron flash support.
 
 - Add support for Micron mt35xu01gbba.
 
 - Some SPI controllers like the Intel one on the PCI bus do not support
   the read CR opcode (0x35). Do not use the opcode if the controller
   does not support it.
 
 Aside from these main changes, there is the usual load of API updates,
 kdoc fixes, potential memory leaks fixes, etc.

Linus Torvalds 77956cf364 pwm: Changes for v6.19-rc1 
Additional to the usual mix of core cleanups, driver changes, minor
 fixes and device tree updates the highlight this cycle is Rust support
 for the core and a first Rust driver both provided by Michal Wilczynski.
 Michal wrote about these changes on
 https://mwilczynski.dev/posts/bringing-rust-to-the-pwm-subsystem/ which
 is a nice read.

Linus Torvalds 2aa680df68 sound updates for 6.19-rc1 
The majority of changes at this time were about ASoC with a lot of
 code refactoring works.  From the functionality POV, there aren't much
 to see, but we have a wide range of device-specific fixes and updates.
 Here are some highlights:
 
 - Continued ASoC API clean works, spanned over many files
 - Added a SoundWire SCDA generic class driver with regmap support
 - Enhancements and fixes for Cirrus, Intel, Maxim and Qualcomm.
 - Support for ASoC Allwinner A523, Mediatek MT8189, Qualcomm QCM2290,
   QRB2210 and SM6115, SpacemiT K1, and TI TAS2568, TAS5802, TAS5806,
   TAS5815, TAS5828 and TAS5830
 - Usual HD-audio and USB-audio quirks and fixups
 - Support for Onkyo SE-300PCIE, TASCAM IF-FW/DM MkII
 
 Some gpiolib changes for shared GPIOs are included along with this PR
 for covering ASoC drivers changes.

Merge tag 'drm-next-2025-12-03' of https://gitlab.freedesktop.org/drm/kernel

Pull drm updates from Dave Airlie:
 "There was a rather late merge of a new color pipeline feature, that
  some userspace projects are blocked on, and has seen a lot of work in
  amdgpu. This should have seen some time in -next. There is additional
  support for this for Intel, that if it arrives in the next day or two
  I'll pass it on in another pull request and you can decide if you want
  to take it.

  Highlights:
   - Arm Ethos NPU accelerator driver

Pull hfs/hfsplus updates from Viacheslav Dubeyko:
 "Several fixes for syzbot reported issues, HFS/HFS+ fixes of xfstests
  failures, Kunit-based unit-tests introduction, and code cleanup:

   - Dan Carpenter fixed a potential use-after-free issue in
     hfs_correct_next_unused_CNID() method. Tetsuo Handa has made nice
     fix of syzbot reported issue related to incorrect inode->i_mode
     management if volume has been corrupted somehow. Yang Chenzhi has
     made really good fix of potential race condition in
     __hfs_bnode_create() method for HFS+ file system.

   - Several fixes to xfstests failures. Particularly, generic/070,
     generic/073, and generic/101 test-cases finish successfully for the
     case of HFS+ file system right now.

   - HFS and HFS+ drivers share multiple structures of on-disk layout
     declarations. Some structures are used without any change. However,
     we had two independent declarations of the same structures in HFS
     and HFS+ drivers.

     The on-disk layout declarations have been moved into
     include/linux/hfs_common.h with the goal to exclude the
     declarations duplication and to keep the HFS/HFS+ on-disk layout
     declarations in one place.

     Also, this patch prepares the basis for creating a hfslib that can
     aggregate common functionality without necessity to duplicate the
     same code in HFS and HFS+ drivers.

   - HFS/HFS+ really need unit-tests because of multiple xfstests
     failures. The first two patches introduce Kunit-based unit-tests
     for the case string operations in HFS/HFS+ file system drivers"

Merge tag 'for-6.19-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux

Pull btrfs updates from David Sterba:
 "Features:

   - shutdown ioctl support (needs CONFIG_BTRFS_EXPERIMENTAL for now):
      - set filesystem state as being shut down (also named going down
        in other filesystems), where all active operations return EIO
        and this cannot be changed until unmount
      - pending operations are attempted to be finished but error
        messages may still show up depending on where exactly the
        shutdown happened

   - scrub (and device replace) vs suspend/hibernate:
      - a running scrub will prevent suspend, which can be annoying as
        suspend is an immediate request and scrub is not critical
      - filesystem freezing before suspend was not sufficient as the
        problem was in process freezing
      - behaviour change: on suspend scrub and device replace are
        cancelled, where scrub can record the last state and continue
        from there; the device replace has to be restarted from the
        beginning

   - zone stats exported in sysfs, from the perspective of the
     filesystem this includes active, reclaimable, relocation etc zones

  Performance:

   - improvements when processing space reservation tickets by
     optimizing locking and shrinking critical sections, cumulative
     improvements in lockstat numbers show +15%

  Notable fixes:

   - use vmalloc fallback when allocating bios as high order allocations
     can happen with wide checksums (like sha256)

   - scrub will always track the last position of progress so it's not
     starting from zero after an error

  Core:

   - under experimental config, checksum calculations are offloaded to
     process context, simplifies locking and allows to remove
     compression write worker kthread(s):
      - speed improvement in direct IO throughput with buffered IO
        fallback is +15% when not offloaded but this is more related to
        internal crypto subsystem improvements
      - this will be probably default in the future removing the sysfs
        tunable

   - (experimental) block size > page size updates:
      - support more operations when not using large folios (encoded
        read/write and send)
      - raid56

   - more preparations for fscrypt support

  Other:

   - more conversions to auto-cleaned variables

   - parameter cleanups and removals

   - extended warning fixes

   - improved printing of structured values like keys

   - lots of other cleanups and refactoring"

Merge tag 'for-6.19/io_uring-20251201' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux

Pull io_uring updates from Jens Axboe:

 - Unify how task_work cancelations are detected, placing it in the
   task_work running state rather than needing to check the task state

 - Series cleaning up and moving the cancelation code to where it
   belongs, in cancel.c

 - Cleanup of waitid and futex argument handling

 - Add support for mixed sized SQEs. 6.18 added support for mixed sized
   CQEs, improving flexibility and efficiency of workloads that need big
   CQEs. This adds similar support for SQEs, where the occasional need
   for a 128b SQE doesn't necessitate having all SQEs be 128b in size

 - Introduce zcrx and SQ/CQ layout queries. The former returns what zcrx
   features are available. And both return the ring size information to
   help with allocation size calculation for user provided rings like
   IORING_SETUP_NO_MMAP and IORING_MEM_REGION_TYPE_USER

 - Zcrx updates for 6.19. It includes a bunch of small patches,
   IORING_REGISTER_ZCRX_CTRL and RQ flushing and David's work on sharing
   zcrx b/w multiple io_uring instances

 - Series cleaning up ring initializations, notable deduplicating ring
   size and offset calculations. It also moves most of the checking
   before doing any allocations, making the code simpler

 - Add support for getsockname and getpeername, which is mostly a
   trivial hookup after a bit of refactoring on the networking side

 - Various fixes and cleanups

Linus Torvalds 8f7aa3d3c7 Networking changes for 6.19. 
Core & protocols
 ----------------
 
  - Replace busylock at the Tx queuing layer with a lockless list. Resulting
    in a 300% (4x) improvement on heavy TX workloads, sending twice the
    number of packets per second, for half the cpu cycles.
 
  - Allow constantly busy flows to migrate to a more suitable CPU/NIC
    queue. Normally we perform queue re-selection when flow comes out
    of idle, but under extreme circumstances the flows may be constantly
    busy. Add sysctl to allow periodic rehashing even if it'd risk packet
    reordering.
 
  - Optimize the NAPI skb cache, make it larger, use it in more paths.
 
  - Attempt returning Tx skbs to the originating CPU (like we already did
    for Rx skbs).
 
  - Various data structure layout and prefetch optimizations from Eric.
 
  - Remove ktime_get() from the recvmsg() fast path, ktime_get() is sadly
    quite expensive on recent AMD machines.
 
  - Extend threaded NAPI polling to allow the kthread busy poll for packets.
 
  - Make MPTCP use Rx backlog processing. This lowers the lock pressure,
    improving the Rx performance.
 
  - Support memcg accounting of MPTCP socket memory.
 
  - Allow admin to opt sockets out of global protocol memory accounting
    (using a sysctl or BPF-based policy). The global limits are a poor fit
    for modern container workloads, where limits are imposed using cgroups.
 
  - Improve heuristics for when to kick off AF_UNIX garbage collection.
 
  - Allow users to control TCP SACK compression, and default to 33% of RTT.
 
  - Add tcp_rcvbuf_low_rtt sysctl to let datacenter users avoid unnecessarily
    aggressive rcvbuf growth and overshot when the connection RTT is low.
 
  - Preserve skb metadata space across skb_push / skb_pull operations.
 
  - Support for IPIP encapsulation in the nftables flowtable offload.
 
  - Support appending IP interface information to ICMP messages (RFC 5837).
 
  - Support setting max record size in TLS (RFC 8449).
 
  - Remove taking rtnl_lock from RTM_GETNEIGHTBL and RTM_SETNEIGHTBL.
 
  - Use a dedicated lock (and RCU) in MPLS, instead of rtnl_lock.
 
  - Let users configure the number of write buffers in SMC.
 
  - Add new struct sockaddr_unsized for sockaddr of unknown length,
    from Kees.
 
  - Some conversions away from the crypto_ahash API, from Eric Biggers.
 
  - Some preparations for slimming down struct page.
 
  - YAML Netlink protocol spec for WireGuard.
 
  - Add a tool on top of YAML Netlink specs/lib for reporting commonly
    computed derived statistics and summarized system state.

  - Add DPLL phase-adjust-gran pin attribute (and implement it in zl3073x).
 
  - Refactor xfrm_input lock to reduce contention when NIC offloads IPsec
    and performs RSS.
 
  - Add info to devlink params whether the current setting is the default
    or a user override. Allow resetting back to default.
 
  - Add standard device stats for PSP crypto offload.
 
  - Leverage DSA frame broadcast to implement simple HSR frame duplication
    for a lot of switches without dedicated HSR offload.
 
  - Add uAPI defines for 1.6Tbps link modes.

Linus Torvalds 784faa8eca Rust changes for v6.19 
Toolchain and infrastructure:
 
  - Add support for 'syn'.
 
      Syn is a parsing library for parsing a stream of Rust tokens into a
      syntax tree of Rust source code.
 
      Currently this library is geared toward use in Rust procedural
      macros, but contains some APIs that may be useful more generally.
 
    'syn' allows us to greatly simplify writing complex macros such as
    'pin-init' (Benno has already prepared the 'syn'-based version). We
    will use it in the 'macros' crate too.
 
    'syn' is the most downloaded Rust crate (according to crates.io), and
    it is also used by the Rust compiler itself. While the amount of code
    is substantial, there should not be many updates needed for these
    crates, and even if there are, they should not be too big, e.g. +7k
    -3k lines across the 3 crates in the last year.
 
    'syn' requires two smaller dependencies: 'quote' and 'proc-macro2'.
    I only modified their code to remove a third dependency
    ('unicode-ident') and to add the SPDX identifiers. The code can be
    easily verified to exactly match upstream with the provided scripts.
 
    They are all licensed under "Apache-2.0 OR MIT", like the other
    vendored 'alloc' crate we had for a while.
 
    Please see the merge commit with the cover letter for more context.
 
  - Allow 'unreachable_pub' and 'clippy::disallowed_names' for doctests.
 
    Examples (i.e. doctests) may want to do things like show public items
    and use names such as 'foo'.
 
    Nevertheless, we still try to keep examples as close to real code as
    possible (this is part of why running Clippy on doctests is important
    for us, e.g. for safety comments, which userspace Rust does not
    support yet but we are stricter).
 
 'kernel' crate:
 
  - Replace our custom 'CStr' type with 'core::ffi::CStr'.
 
    Using the standard library type reduces our custom code footprint,
    and we retain needed custom functionality through an extension trait
    and a new 'fmt!' macro which replaces the previous 'core' import.
 
    This started in 6.17 and continued in 6.18, and we finally land the
    replacement now. This required quite some stamina from Tamir, who
    split the changes in steps to prepare for the flag day change here.
 
  - Replace 'kernel::c_str!' with C string literals.
 
    C string literals were added in Rust 1.77, which produce '&CStr's
    (the 'core' one), so now we can write:
 
        c"hi"
 
    instead of:
 
        c_str!("hi")
 
  - Add 'num' module for numerical features.
 
    It includes the 'Integer' trait, implemented for all primitive
    integer types.
 
    It also includes the 'Bounded' integer wrapping type: an integer
    value that requires only the 'N' less significant bits of the wrapped
    type to be encoded:
 
        // An unsigned 8-bit integer, of which only the 4 LSBs are used.
        let v = Bounded::<u8, 4>:🆕:<15>();
        assert_eq!(v.get(), 15);
 
    'Bounded' is useful to e.g. enforce guarantees when working with
    bitfields that have an arbitrary number of bits.
 
    Values can be constructed from simple non-constant expressions or,
    for more complex ones, validated at runtime.
 
    'Bounded' also comes with comparison and arithmetic operations (with
    both their backing type and other 'Bounded's with a compatible
    backing type), casts to change the backing type, extending/shrinking
    and infallible/fallible conversions from/to primitives as applicable.
 
  - 'rbtree' module: add immutable cursor ('Cursor').
 
    It enables to use just an immutable tree reference where appropriate.
    The existing fully-featured mutable cursor is renamed to 'CursorMut'.
 
 kallsyms:
 
  - Fix wrong "big" kernel symbol type read from procfs.
 
 'pin-init' crate:
 
  - A couple minor fixes (Benno asked me to pick these patches up for
    him this cycle).
 
 Documentation:
 
  - Quick Start guide: add Debian 13 (Trixie).
 
    Debian Stable is now able to build Linux, since Debian 13 (released
    2025-08-09) packages Rust 1.85.0, which is recent enough.
 
    We are planning to propose that the minimum supported Rust version in
    Linux follows Debian Stable releases, with Debian 13 being the first
    one we upgrade to, i.e. Rust 1.85.
 
 MAINTAINERS:
 
  - Add entry for the new 'num' module.
 
  - Remove Alex as Rust maintainer: he hasn't had the time to contribute
    for a few years now, so it is a no-op change in practice.
 
 And a few other cleanups and improvements.

     ('unicode-ident') and to add the SPDX identifiers. The code can be
     easily verified to exactly match upstream with the provided
     scripts.

     They are all licensed under "Apache-2.0 OR MIT", like the other
     vendored 'alloc' crate we had for a while.

     Please see the merge commit with the cover letter for more context.

   - Allow 'unreachable_pub' and 'clippy::disallowed_names' for
     doctests.

     Examples (i.e. doctests) may want to do things like show public
     items and use names such as 'foo'.

     Nevertheless, we still try to keep examples as close to real code
     as possible (this is part of why running Clippy on doctests is
     important for us, e.g. for safety comments, which userspace Rust
     does not support yet but we are stricter).

  'kernel' crate:

   - Replace our custom 'CStr' type with 'core::ffi::CStr'.

     Using the standard library type reduces our custom code footprint,
     and we retain needed custom functionality through an extension
     trait and a new 'fmt!' macro which replaces the previous 'core'
     import.

     This started in 6.17 and continued in 6.18, and we finally land the
     replacement now. This required quite some stamina from Tamir, who
     split the changes in steps to prepare for the flag day change here.

   - Replace 'kernel::c_str!' with C string literals.

     C string literals were added in Rust 1.77, which produce '&CStr's
     (the 'core' one), so now we can write:

         c"hi"

     instead of:

         c_str!("hi")

   - Add 'num' module for numerical features.

     It includes the 'Integer' trait, implemented for all primitive
     integer types.

     It also includes the 'Bounded' integer wrapping type: an integer
     value that requires only the 'N' least significant bits of the
     wrapped type to be encoded:

         // An unsigned 8-bit integer, of which only the 4 LSBs are used.
         let v = Bounded::<u8, 4>:🆕:<15>();
         assert_eq!(v.get(), 15);

     'Bounded' is useful to e.g. enforce guarantees when working with
     bitfields that have an arbitrary number of bits.

     Values can also be constructed from simple non-constant expressions
     or, for more complex ones, validated at runtime.

     'Bounded' also comes with comparison and arithmetic operations
     (with both their backing type and other 'Bounded's with a
     compatible backing type), casts to change the backing type,
     extending/shrinking and infallible/fallible conversions from/to
     primitives as applicable.

   - 'rbtree' module: add immutable cursor ('Cursor').

     It enables to use just an immutable tree reference where
     appropriate. The existing fully-featured mutable cursor is renamed
     to 'CursorMut'.

  kallsyms:

   - Fix wrong "big" kernel symbol type read from procfs.

  'pin-init' crate:

   - A couple minor fixes (Benno asked me to pick these patches up for
     him this cycle).

  Documentation:

   - Quick Start guide: add Debian 13 (Trixie).

     Debian Stable is now able to build Linux, since Debian 13 (released
     2025-08-09) packages Rust 1.85.0, which is recent enough.

     We are planning to propose that the minimum supported Rust version
     in Linux follows Debian Stable releases, with Debian 13 being the
     first one we upgrade to, i.e. Rust 1.85.

  MAINTAINERS:

   - Add entry for the new 'num' module.

   - Remove Alex as Rust maintainer: he hasn't had the time to
     contribute for a few years now, so it is a no-op change in
     practice.

  And a few other cleanups and improvements"

Linus Torvalds 02baaa67d9 sched_ext: Changes for v6.19 
- Improve recovery from misbehaving BPF schedulers. When a scheduler puts many
   tasks with varying affinity restrictions on a shared DSQ, CPUs scanning
   through tasks they cannot run can overwhelm the system, causing lockups.
   Bypass mode now uses per-CPU DSQs with a load balancer to avoid this, and
   hooks into the hardlockup detector to attempt recovery. Add scx_cpu0 example

 - Allow scx_bpf_reenqueue_local() to be called from anywhere in preparation for

Merge tag 'printk-for-6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux

Pull printk updates from Petr Mladek:

 - Allow creaing nbcon console drivers with an unsafe write_atomic()
   callback that can only be called by the final nbcon_atomic_flush_unsafe().
   Otherwise, the driver would rely on the kthread.

   It is going to be used as the-best-effort approach for an
   experimental nbcon netconsole driver, see

     https://lore.kernel.org/r/20251121-nbcon-v1-2-503d17b2b4af@debian.org

   Note that a safe .write_atomic() callback is supposed to work in NMI
   context. But some networking drivers are not safe even in IRQ
   context:

     https://lore.kernel.org/r/oc46gdpmmlly5o44obvmoatfqo5bhpgv7pabpvb6sjuqioymcg@gjsma3ghoz35

   In an ideal world, all networking drivers would be fixed first and
   the atomic flush would be blocked only in NMI context. But it brings
   the question how reliable networking drivers are when the system is
   in a bad state. They might block flushing more reliable serial
   consoles which are more suitable for serious debugging anyway.

 - Allow to use the last 4 bytes of the printk ring buffer.

 - Prevent queuing IRQ work and block printk kthreads when consoles are
   suspended. Otherwise, they create non-necessary churn or even block
   the suspend.

 - Release console_lock() between each record in the kthread used for
   legacy consoles on RT. It might significantly speed up the boot.

 - Release nbcon context between each record in the atomic flush. It
   prevents stalls of the related printk kthread after it has lost the
   ownership in the middle of a record

 - Add support for NBCON consoles into KDB

 - Add %ptsP modifier for printing struct timespec64 and use it where
   possible

 - Misc code clean up

SRCU
 ----
 
 _ Properly handle SRCU readers within IRQ disabled sections in tiny SRCU
 
 - Preparation to reimplement RCU Tasks Trace on top of SRCU fast:
 
     - Introduce API to expedite a grace period and test it through
       rcutorture.
 
     - Split srcu-fast in two flavours: SRCU-fast and SRCU-fast-updown.
       Both are still targeted toward faster readers (without full
       barriers on LOCK and UNLOCK) at the expense of heavier write side
       (using full RCU grace period ordering instead of simply full
       ordering) as compared to "traditional" non-fast SRCU. But those
       srcu-fast flavours are going to be optimized in two different
       ways:
 
          - SRCU-fast will become the reimplementation basis for
            RCU-TASK-TRACE for consolidation. Since RCU-TASK-TRACE must
            be NMI safe, SRCU-fast must be as well.
 
          - SRCU-fast-updown will be needed for uretprobes code in order
            to get rid of the read-side memory barriers while still
            allowing entering the reader at task level while exiting it
            in a timer handler. It is considered semaphore-like in that
            it can have different owners between LOCK and UNLOCK.
            However it is not NMI-safe.
 
       The actual optimizations are work in progress for the next cycle.
       Only the new interfaces are added for now, along with related
       torture and scalability test code.
 
 - Create/document/debug/torture new proper initializers for RCU fast:
   DEFINE_SRCU_FAST() and init_srcu_struct_fast()
 
   This allows for using right away the proper ordering on the write
   side (either full ordering or full RCU grace period ordering) without
   waiting for the read side to tell which to use. Also this optimizes
   the read side altogether with moving flavour debug checks under debug
   config and with removing a costly RmW operation on their first call.
 
 - Make some diagnostic functions tracing safe.
 
 REFSCALE
 -------
 
 Add performance testing for common context synchronizations
 (Preemption, IRQ, Softirq) and per-cpu increments. Those are
 relevant comparisons against SRCU-fast read side APIs, especially
 as they are planned to synchronize further tracing fast-path code.
 
 MISCELLANOUS
 ------
 
 - In order to prepare the layout for nohz_full work deferral to
   user exit, the context tracking state must shrink the counter
   of transitions to/from RCU not watching. The only possible hazard
   is to trigger wrap-around more easily, delaying a bit grace periods
   when that happens. This should be a rare event though. Yet add
   debugging and torture code to test that assumption.
 
 - Fix memory leak on locktorture module
 
 - Annotate accesses in rculist_nulls.h to prevent from KCSAN warnings.
   On recent discussions, we also concluded that all those WRITE_ONCE()
   and READ_ONCE() on list APIs deserve appropriate comments. Something
   to be expected for the next cycle.
 
 - Provide a script to apply several configs to several commits with torture.
 
 - Allow torture to reuse a build directory in order to save needless
   rebuild time.
 
 - Various cleanups.

Pull RCU updates from Frederic Weisbecker:
 "SRCU:

   - Properly handle SRCU readers within IRQ disabled sections in tiny
     SRCU

   - Preparation to reimplement RCU Tasks Trace on top of SRCU fast:

      - Introduce API to expedite a grace period and test it through
        rcutorture

      - Split srcu-fast in two flavours: SRCU-fast and SRCU-fast-updown.

        Both are still targeted toward faster readers (without full
        barriers on LOCK and UNLOCK) at the expense of heavier write
        side (using full RCU grace period ordering instead of simply
        full ordering) as compared to "traditional" non-fast SRCU. But
        those srcu-fast flavours are going to be optimized in two
        different ways:

          - SRCU-fast will become the reimplementation basis for
            RCU-TASK-TRACE for consolidation. Since RCU-TASK-TRACE must
            be NMI safe, SRCU-fast must be as well.

Linus Torvalds f96163865a This has been another busy cycle for documentation, with a lot of 
build-system thrashing.  That work should slow down from here on out.
 
 - The various scripts and tools for documentation were spread out in
   several directories; now they are (almost) all coalesced under
   tools/docs/.  The holdout is the kernel-doc script, which cannot be
   easily moved without some further thought.
 
 - As the amount of Python code increases, we are accumulating modules that
   are imported by multiple programs.  These modules have been pulled
   together under tools/lib/python/ -- at least, for documentation-related
   programs.  There is other Python code in the tree that might eventually
   want to move toward this organization.
 
 - The Perl kernel-doc.pl script has been removed.  It is no longer used by
   default, and nobody has missed it, least of all anybody who actually had
   to look at it.
 
 - The docs build was controlled by a complex mess of makefilese that few
   dared to touch.  Mauro has moved that logic into a new program
   (tools/docs/sphinx-build-wrapper) that, with any luck at all, will be far
   easier to understand and maintain.
 
 - The get_feat.pl program, used to access information under
   Documentation/features/, has been rewritten in Python, bringing an end to
   the use of Perl in the docs subsystem.
 
 - The top-level README file has been reorganized into a more
   reader-friendly presentation.

Pull audit updates from Paul Moore:

 - Consolidate the loops in __audit_inode_child() to improve performance

   When logging a child inode in __audit_inode_child(), we first run
   through the list of recorded inodes looking for the parent and then
   we repeat the search looking for a matching child entry. This pull
   request consolidates both searches into one pass through the recorded
   inodes, resuling in approximately a 50% reduction in audit overhead.

   See the commit description for the testing details.

 - Combine kmalloc()/memset() into kzalloc() in audit_krule_to_data()

Merge tag 'selinux-pr-20251201' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux

Pull selinux updates from Paul Moore:

 - Improve the granularity of SELinux labeling for memfd files

   Currently when creating a memfd file, SELinux treats it the same as
   any other tmpfs, or hugetlbfs, file. While simple, the drawback is
   that it is not possible to differentiate between memfd and tmpfs
   files.

   This adds a call to the security_inode_init_security_anon() LSM hook
   and wires up SELinux to provide a set of memfd specific access
   controls, including the ability to control the execution of memfds.

   As usual, the commit message has more information.

 - Improve the SELinux AVC lookup performance

   Adopt MurmurHash3 for the SELinux AVC hash function instead of the
   custom hash function currently used. MurmurHash3 is already used for
   the SELinux access vector table so the impact to the code is minimal,
   and performance tests have shown improvements in both hash
   distribution and latency.

   See the commit message for the performance measurments.

 - Introduce a Kconfig option for the SELinux AVC bucket/slot size

   While we have the ability to grow the number of AVC hash buckets
   today, the size of the buckets (slot size) is fixed at 512. This pull
   request makes that slot size configurable at build time through a new
   Kconfig knob, CONFIG_SECURITY_SELINUX_AVC_HASH_BITS.

Merge tag 'lsm-pr-20251201' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm

Pull LSM updates from Paul Moore:

 - Rework the LSM initialization code

   What started as a "quick" patch to enable a notification event once
   all of the individual LSMs were initialized, snowballed a bit into a
   30+ patch patchset when everything was done. Most of the patches, and
   diffstat, is due to splitting out the initialization code into
   security/lsm_init.c and cleaning up some of the mess that was there.
   While not strictly necessary, it does cleanup the code signficantly,
   and hopefully makes the upkeep a bit easier in the future.

   Aside from the new LSM_STARTED_ALL notification, these changes also
   ensure that individual LSM initcalls are only called when the LSM is
   enabled at boot time. There should be a minor reduction in boot times
   for those who build multiple LSMs into their kernels, but only enable
   a subset at boot.

   It is worth mentioning that nothing at present makes use of the
   LSM_STARTED_ALL notification, but there is work in progress which is
   dependent upon LSM_STARTED_ALL.
