f3ddc438a2 arm64 fixes for 6.13-rc2: 
- MTE/hugetlbfs:
 
   - Set VM_MTE_ALLOWED in the arch code and remove it from the core code
     for hugetlbfs mappings
 
   - Fix copy_highpage() warning when the source is a huge page but not
     MTE tagged, taking the wrong small page path
 
 - drivers/virt/coco:
 
   - Add the pKVM and Arm CCA drivers under the arm64 maintainership
 
   - Fix the pkvm driver to fall back to ioremap() (and warn) if the
     MMIO_GUARD hypercall fails
 
   - Keep the Arm CCA driver default 'n' rather than 'm'
 
 - A series of fixes for the arm64 ptrace() implementation, potentially
   leading to the kernel consuming uninitialised stack variables when
   PTRACE_SETREGSET is invoked with a length of 0
 
 - Fix zone_dma_limit calculation when RAM starts below 4GB and ZONE_DMA
   is capped to this limit
 
 - Fix early boot warning with CONFIG_DEBUG_VIRTUAL=y triggered by a call
   to page_to_phys() (from patch_map()) which checks pfn_valid() before
   vmemmap has been set up
 
 - Do not clobber bits 15:8 of the ASID used for TTBR1_EL1 and TLBI ops
   when the kernel assumes 8-bit ASIDs but running under a hypervisor on
   a system that implements 16-bit ASIDs (found running Linux under
   Parallels on Apple M4)
 
 - ACPI/IORT: Add PMCG platform information for HiSilicon HIP09A as it is
   using the same SMMU PMCG as HIP09 and suffers from the same errata
 
 - Add GCS to cpucap_is_possible(), missed in the recent merge

9223059625 MAINTAINERS: Add CCA and pKVM CoCO guest support to the ARM64 entry 
Commits 7999edc484 ("virt: arm-cca-guest: TSM_REPORT support for
realm") and a06c3fad49 ("drivers/virt: pkvm: Add initial support for
running as a protected guest") added arm64 guest-side support for
running in CCA and pKVM confidential computing environments
respectively.

Unfortunately, these changes were not accompanied by a MAINTAINERS
entry and so aren't automatically picked up by the get_maintainer.pl
script. Since the initial support was merged via the arm64 tree, extend
the ARM64 entry to cover the two new directories.

Thanks to the real entry using drivers/ptp/* the original entry will
still be considered more specific / higher prio.

a14bf463e7 i2c-for-6.13-rc1-part3 
core: add of based component probing
 
 Some devices are designed and manufactured with some components having
 multiple drop-in replacement options. These components are often
 connected to the mainboard via ribbon cables, having the same signals
 and pin assignments across all options. These may include the display
 panel and touchscreen on laptops and tablets, and the trackpad on
 laptops. Sometimes which component option is used in a particular device
 can be detected by some firmware provided identifier, other times that
 information is not available, and the kernel has to try to probe each
 device.
 
 Instead of a delicate dance between drivers and device tree quirks, this
 change introduces a simple I2C component probe function. For a given
 class of devices on the same I2C bus, it will go through all of them,
 doing a simple I2C read transfer and see which one of them responds. It
 will then enable the device that responds.

2eff01ee28 Char/Misc/IIO/Whatever driver subsystem updates for 6.13-rc1 
Here is the "big and hairy" char/misc/iio and other small driver
 subsystem updates for 6.13-rc1.  Sorry for doing this at the end of the
 merge window, conference and holiday travel got in the way on my side
 (hence the 5am pull request emails...)
 
 Loads of things in here, and even a fun merge conflict!
   - rust misc driver bindings and other rust changes to make misc
     drivers actually possible.  I think this is the tipping point,
     expect to see way more rust drivers going forward now that these
     bindings are present.  Next merge window hopefully we will have pci
     and platform drivers working, which will fully enable almost all
     driver subsystems to start accepting (or at least getting) rust
     drivers.  This is the end result of a lot of work from a lot of
     people, congrats to all of them for getting this far, you've proved
     many of us wrong in the best way possible, working code :)
   - IIO driver updates, too many to list individually, that subsystem
     keeps growing and growing...
   - Interconnect driver updates
   - nvmem driver updates
   - pwm driver updates
   - platform_driver::remove() fixups, loads of them
   - counter driver updates
   - misc driver updates (keba?)
   - binder driver updates and fixes
   - loads of other small char/misc/etc driver updates and additions,
     full details in the shortlog.
 
 Note, there is a semi-hairy rust merge conflict when pulling this.  The
 resolution has been in linux-next for a while and can be seen here:
 	https://lore.kernel.org/all/20241111173459.2646d4af@canb.auug.org.au/
 
 All of these have been in linux-next for a while, with no other reported
 issues other than that merge conflict.

a0c1ca3934 Staging driver changes for 6.13-rc1 
Here is the big set of staging driver changes for 6.13-rc1.
 
 Lots of changes this merge cycle, drivers removed and drivers added.
 Highlights include:
   - removals of the following staging drivers due to no forward progress
     and no one having either the hardware or the time/energy to deal
     with them anymore:
       - fieldbus
       - gdm724x
       - olpc_dcon
       - rtl8712
       - rts5208
       - vt6655
       - vt6656
     If anyone has this hardware and wants to work on the drivers, it can
     be an easy revert to get them back.
  - addition of the gpib driver subsystem.  Lots of drivers for
    really old and semi-old interfaces to lab equipments.  We expect lots
    of churn in these drivers as they get cleaned up to "working" order.
    These were added at the request of a user and the maintainer/author
    of them is helping out with the effort
  - loads and loads of tiny coding style cleanups for almost all staging
    drivers.  Too many to list, see the shortlog for details.
 
 Note, this pull request contains a portion of the wireless tree, as the
 removal of some of the staging wifi drivers came in through there to
 coordinate things.  These should already be in your tree already, so the
 diffstat will (and should) look different when you do your merge.
 
 All of these have been in linux-next for a very long time with no
 reported issues.

157ce8f381 i2c: Introduce OF component probe function 
Some devices are designed and manufactured with some components having
multiple drop-in replacement options. These components are often
connected to the mainboard via ribbon cables, having the same signals
and pin assignments across all options. These may include the display
panel and touchscreen on laptops and tablets, and the trackpad on
laptops. Sometimes which component option is used in a particular device
can be detected by some firmware provided identifier, other times that
information is not available, and the kernel has to try to probe each
device.

This change attempts to make the "probe each device" case cleaner. The
current approach is to have all options added and enabled in the device
tree. The kernel would then bind each device and run each driver's probe
function. This works, but has been broken before due to the introduction
of asynchronous probing, causing multiple instances requesting "shared"
resources, such as pinmuxes, GPIO pins, interrupt lines, at the same
time, with only one instance succeeding. Work arounds for these include
moving the pinmux to the parent I2C controller, using GPIO hogs or
pinmux settings to keep the GPIO pins in some fixed configuration, and
requesting the interrupt line very late. Such configurations can be seen
on the MT8183 Krane Chromebook tablets, and the Qualcomm sc8280xp-based
Lenovo Thinkpad 13S.

Instead of this delicate dance between drivers and device tree quirks,
this change introduces a simple I2C component probe function. For a
given class of devices on the same I2C bus, it will go through all of
them, doing a simple I2C read transfer and see which one of them responds.
It will then enable the device that responds.

This requires some minor modifications in the existing device tree. The
status for all the device nodes for the component options must be set
to "fail-needs-probe". This makes it clear that some mechanism is
needed to enable one of them, and also prevents the prober and device
drivers running at the same time.

Pull PCI updates from Bjorn Helgaas:
 "Enumeration:

   - Make pci_stop_dev() and pci_destroy_dev() safe so concurrent
     callers can't stop a device multiple times, even as we migrate from
     the global pci_rescan_remove_lock to finer-grained locking (Keith
     Busch)

   - Improve pci_walk_bus() implementation by making it recursive and
     moving locking up to avoid need for a 'locked' parameter (Keith
     Busch)

   - Unexport pci_walk_bus_locked(), which is only used internally by
     the PCI core (Keith Busch)

   - Detect some Thunderbolt chips that are built-in and hence
     'trustworthy' by a heuristic since the 'ExternalFacingPort' and
     'usb4-host-interface' ACPI properties are not quite enough (Esther
     Shimanovich)

  Resource management:

   - Use PCI bus addresses (not CPU addresses) in 'ranges' properties
     when building dynamic DT nodes so systems where PCI and CPU
     addresses differ work correctly (Andrea della Porta)

   - Tidy resource sizing and assignment with helpers to reduce
     redundancy (Ilpo Järvinen)

   - Improve pdev_sort_resources() 'bogus alignment' warning to be more
     specific (Ilpo Järvinen)

  Driver binding:

   - Convert driver .remove_new() callbacks to .remove() again to finish
     the conversion from returning 'int' to being 'void' (Sergio
     Paracuellos)

   - Export pcim_request_all_regions(), a managed interface to request
     all BARs (Philipp Stanner)

   - Replace pcim_iomap_regions_request_all() with
     pcim_request_all_regions(), and pcim_iomap_table()[n] with
     pcim_iomap(n), in the following drivers: ahci, crypto qat, crypto
     octeontx2, intel_th, iwlwifi, ntb idt, serial rp2, ALSA korg1212
     (Philipp Stanner)

   - Remove the now unused pcim_iomap_regions_request_all() (Philipp
     Stanner)

   - Export pcim_iounmap_region(), a managed interface to unmap and
     release a PCI BAR (Philipp Stanner)

   - Replace pcim_iomap_regions(mask) with pcim_iomap_region(n), and
     pcim_iounmap_regions(mask) with pcim_iounmap_region(n), in the
     following drivers: fpga dfl-pci, block mtip32xx, gpio-merrifield,
     cavium (Philipp Stanner)

  Error handling:

   - Add sysfs 'reset_subordinate' to reset the entire hierarchy below a
     bridge; previously Secondary Bus Reset could only be used when
     there was a single device below a bridge (Keith Busch)

   - Warn if we reset a running device where the driver didn't register
     pci_error_handlers notification callbacks (Keith Busch)

  ASPM:

   - Disable ASPM L1 before touching L1 PM Substates to follow the spec
     closer and avoid a CPU load timeout on some platforms (Ajay
     Agarwal)

   - Set devices below Intel VMD to D0 before enabling ASPM L1 Substates
     as required per spec for all L1 Substates changes (Jian-Hong Pan)

  Power management:

   - Enable starfive controller runtime PM before probing host bridge
     (Mayank Rana)

   - Enable runtime power management for host bridges (Krishna chaitanya
     chundru)

  Power control:

   - Use of_platform_device_create() instead of of_platform_populate()
     to create pwrctl platform devices so we can control it based on the
     child nodes (Manivannan Sadhasivam)

   - Create pwrctrl platform devices only if there's a relevant power
     supply property (Manivannan Sadhasivam)

   - Add device link from the pwrctl supplier to the PCI dev to ensure
     pwrctl drivers are probed before the PCI dev driver; this avoids a
     race where pwrctl could change device power state while the PCI
     driver was active (Manivannan Sadhasivam)

   - Find pwrctl device for removal with of_find_device_by_node()
     instead of searching all children of the parent (Manivannan
     Sadhasivam)

   - Rename 'pwrctl' to 'pwrctrl' to match new bandwidth controller
     ('bwctrl') and hotplug files (Bjorn Helgaas)

  Bandwidth control:

   - Add read/modify/write locking for Link Control 2, which is used to
     manage Link speed (Ilpo Järvinen)

   - Extract Link Bandwidth Management Status check into
     pcie_lbms_seen(), where it can be shared between the bandwidth
     controller and quirks that use it to help retrain failed links
     (Ilpo Järvinen)

   - Re-add Link Bandwidth notification support with updates to address
     the reasons it was previously reverted (Alexandru Gagniuc, Ilpo
     Järvinen)

   - Add pcie_set_target_speed() and related functionality so drivers
     can manage PCIe Link speed based on thermal or other constraints
     (Ilpo Järvinen)

   - Add a thermal cooling driver to throttle PCIe Links via the
     existing thermal management framework (Ilpo Järvinen)

   - Add a userspace selftest for the PCIe bandwidth controller (Ilpo
     Järvinen)

  PCI device hotplug:

   - Add hotplug controller driver for Marvell OCTEON multi-function
     device where function 0 has a management console interface to
     enable/disable and provision various personalities for the other
     functions (Shijith Thotton)

   - Retain a reference to the pci_bus for the lifetime of a pci_slot to
     avoid a use-after-free when the thunderbolt driver resets USB4 host
     routers on boot, causing hotplug remove/add of downstream docks or
     other devices (Lukas Wunner)

   - Remove unused cpcihp struct cpci_hp_controller_ops.hardware_test
     (Guilherme Giacomo Simoes)

   - Remove unused cpqphp struct ctrl_dbg.ctrl (Christophe JAILLET)

   - Use pci_bus_read_dev_vendor_id() instead of hand-coded presence
     detection in cpqphp (Ilpo Järvinen)

   - Simplify cpqphp enumeration, which is already simple-minded and
     doesn't handle devices below hot-added bridges (Ilpo Järvinen)

  Virtualization:

   - Add ACS quirk for Wangxun FF5xxx NICs, which don't advertise an ACS
     capability but do isolate functions as though PCI_ACS_RR and
     PCI_ACS_CR were set, so the functions can be in independent IOMMU
     groups (Mengyuan Lou)

  TLP Processing Hints (TPH):

   - Add and document TLP Processing Hints (TPH) support so drivers can
     enable and disable TPH and the kernel can save/restore TPH
     configuration (Wei Huang)

   - Add TPH Steering Tag support so drivers can retrieve Steering Tag
     values associated with specific CPUs via an ACPI _DSM to improve
     performance by directing DMA writes closer to their consumers (Wei
     Huang)

  Data Object Exchange (DOE):

   - Wait up to 1 second for DOE Busy bit to clear before writing a
     request to the mailbox to avoid failures if the mailbox is still
     busy from a previous transfer (Gregory Price)

  Endpoint framework:

   - Skip attempts to allocate from endpoint controller memory window if
     the requested size is larger than the window (Damien Le Moal)

   - Add and document pci_epc_mem_map() and pci_epc_mem_unmap() to
     handle controller-specific size and alignment constraints, and add
     test cases to the endpoint test driver (Damien Le Moal)

   - Implement dwc pci_epc_ops.align_addr() so pci_epc_mem_map() can
     observe DWC-specific alignment requirements (Damien Le Moal)

   - Synchronously cancel command handler work in endpoint test before
     cleaning up DMA and BARs (Damien Le Moal)

   - Respect endpoint page size in dw_pcie_ep_align_addr() (Niklas
     Cassel)

   - Use dw_pcie_ep_align_addr() in dw_pcie_ep_raise_msi_irq() and
     dw_pcie_ep_raise_msix_irq() instead of open coding the equivalent
     (Niklas Cassel)

   - Avoid NULL dereference if Modem Host Interface Endpoint lacks
     'mmio' DT property (Zhongqiu Han)

   - Release PCI domain ID of Endpoint controller parent (not controller
     itself) and before unregistering the controller, to avoid
     use-after-free (Zijun Hu)

   - Clear secondary (not primary) EPC in pci_epc_remove_epf() when
     removing the secondary controller associated with an NTB (Zijun Hu)

  Cadence PCIe controller driver:

   - Lower severity of 'phy-names' message (Bartosz Wawrzyniak)

  Freescale i.MX6 PCIe controller driver:

   - Fix suspend/resume support on i.MX6QDL, which has a hardware
     erratum that prevents use of L2 (Stefan Eichenberger)

  Intel VMD host bridge driver:

   - Add 0xb60b and 0xb06f Device IDs for client SKUs (Nirmal Patel)

  MediaTek PCIe Gen3 controller driver:

   - Update mediatek-gen3 DT binding to require the exact number of
     clocks for each SoC (Fei Shao)

   - Add support for DT 'max-link-speed' and 'num-lanes' properties to
     restrict the link speed and width (AngeloGioacchino Del Regno)

  Microchip PolarFlare PCIe controller driver:

   - Add DT and driver support for using either of the two PolarFire
     Root Ports (Conor Dooley)

  NVIDIA Tegra194 PCIe controller driver:

   - Move endpoint controller cleanups that depend on refclk from the
     host to the notifier that tells us the host has deasserted PERST#,
     when refclk should be valid (Manivannan Sadhasivam)

  Qualcomm PCIe controller driver:

   - Add qcom SAR2130P DT binding with an additional clock (Dmitry
     Baryshkov)

   - Enable MSI interrupts if 'global' IRQ is supported, since a
     previous commit unintentionally masked them (Manivannan Sadhasivam)

   - Move endpoint controller cleanups that depend on refclk from the
     host to the notifier that tells us the host has deasserted PERST#,
     when refclk should be valid (Manivannan Sadhasivam)

   - Add DT binding and driver support for IPQ9574, with Synopsys IP
     v5.80a and Qcom IP 1.27.0 (devi priya)

   - Move the OPP "operating-points-v2" table from the
     qcom,pcie-sm8450.yaml DT binding to qcom,pcie-common.yaml, where it
     can be used by other Qcom platforms (Qiang Yu)

   - Add 'global' SPI interrupt for events like link-up, link-down to
     qcom,pcie-x1e80100 DT binding so we can start enumeration when the
     link comes up (Qiang Yu)

   - Disable ASPM L0s for qcom,pcie-x1e80100 since the PHY is not tuned
     to support this (Qiang Yu)

   - Add ops_1_21_0 for SC8280X family SoC, which doesn't use the
     'iommu-map' DT property and doesn't need BDF-to-SID translation
     (Qiang Yu)

  Rockchip PCIe controller driver:

   - Define ROCKCHIP_PCIE_AT_SIZE_ALIGN to replace magic 256 endpoint
     .align value (Damien Le Moal)

   - When unmapping an endpoint window, compute the region index instead
     of searching for it, and verify that the address was mapped (Damien
     Le Moal)

   - When mapping an endpoint window, verify that the address hasn't
     been mapped already (Damien Le Moal)

   - Implement pci_epc_ops.align_addr() for rockchip-ep (Damien Le Moal)

   - Fix MSI IRQ data mapping to observe the alignment constraint, which
     fixes intermittent page faults in memcpy_toio() and memcpy_fromio()
     (Damien Le Moal)

   - Rename rockchip_pcie_parse_ep_dt() to
     rockchip_pcie_ep_get_resources() for consistency with similar DT
     interfaces (Damien Le Moal)

   - Skip the unnecessary link train in rockchip_pcie_ep_probe() and do
     it only in the endpoint start operation (Damien Le Moal)

   - Implement pci_epc_ops.stop_link() to disable link training and
     controller configuration (Damien Le Moal)

   - Attempt link training at 5 GT/s when both partners support it
     (Damien Le Moal)

   - Add a handler for PERST# signal so we can detect host-initiated
     resets and start link training after PERST# is deasserted (Damien
     Le Moal)

  Synopsys DesignWare PCIe controller driver:

   - Clear outbound address on unmap so dw_pcie_find_index() won't match
     an ATU index that was already unmapped (Damien Le Moal)

   - Use of_property_present() instead of of_property_read_bool() when
     testing for presence of non-boolean DT properties (Rob Herring)

   - Advertise 1MB size if endpoint supports Resizable BARs, which was
     inadvertently lost in v6.11 (Niklas Cassel)

  TI J721E PCIe driver:

   - Add PCIe support for J722S SoC (Siddharth Vadapalli)

   - Delay PCIE_T_PVPERL_MS (100 ms), not just PCIE_T_PERST_CLK_US (100
     us), before deasserting PERST# to ensure power and refclk are
     stable (Siddharth Vadapalli)

  TI Keystone PCIe controller driver:

   - Set the 'ti,keystone-pcie' mode so v3.65a devices work in Root
     Complex mode (Kishon Vijay Abraham I)

   - Try to avoid unrecoverable SError for attempts to issue config
     transactions when the link is down; this is racy but the best we
     can do (Kishon Vijay Abraham I)

  Miscellaneous:

   - Reorganize kerneldoc parameter names to match order in function
     signature (Julia Lawall)

   - Fix sysfs reset_method_store() memory leak (Todd Kjos)

   - Simplify pci_create_slot() (Ilpo Järvinen)

d5dc958361 kbuild: Add Propeller configuration for kernel build 
Add the build support for using Clang's Propeller optimizer. Like
AutoFDO, Propeller uses hardware sampling to gather information
about the frequency of execution of different code paths within a
binary. This information is then used to guide the compiler's
optimization decisions, resulting in a more efficient binary.

The support requires a Clang compiler LLVM 19 or later, and the
create_llvm_prof tool
(https://github.com/google/autofdo/releases/tag/v0.30.1). This
commit is limited to x86 platforms that support PMU features
like LBR on Intel machines and AMD Zen3 BRS.

Here is an example workflow for building an AutoFDO+Propeller
optimized kernel:

1) Build the kernel on the host machine, with AutoFDO and Propeller
   build config
      CONFIG_AUTOFDO_CLANG=y
      CONFIG_PROPELLER_CLANG=y
   then
      $ make LLVM=1 CLANG_AUTOFDO_PROFILE=<autofdo_profile>

“<autofdo_profile>” is the profile collected when doing a non-Propeller
AutoFDO build. This step builds a kernel that has the same optimization
level as AutoFDO, plus a metadata section that records basic block
information. This kernel image runs as fast as an AutoFDO optimized
kernel.

2) Install the kernel on test/production machines.

3) Run the load tests. The '-c' option in perf specifies the sample
   event period. We suggest using a suitable prime number,
   like 500009, for this purpose.
   For Intel platforms:
      $ perf record -e BR_INST_RETIRED.NEAR_TAKEN:k -a -N -b -c <count> \
        -o <perf_file> -- <loadtest>
   For AMD platforms:
      The supported system are: Zen3 with BRS, or Zen4 with amd_lbr_v2
      # To see if Zen3 support LBR:
      $ cat proc/cpuinfo | grep " brs"
      # To see if Zen4 support LBR:
      $ cat proc/cpuinfo | grep amd_lbr_v2
      # If the result is yes, then collect the profile using:
      $ perf record --pfm-events RETIRED_TAKEN_BRANCH_INSTRUCTIONS:k -a \
        -N -b -c <count> -o <perf_file> -- <loadtest>

4) (Optional) Download the raw perf file to the host machine.

5) Generate Propeller profile:
   $ create_llvm_prof --binary=<vmlinux> --profile=<perf_file> \
     --format=propeller --propeller_output_module_name \
     --out=<propeller_profile_prefix>_cc_profile.txt \
     --propeller_symorder=<propeller_profile_prefix>_ld_profile.txt

   “create_llvm_prof” is the profile conversion tool, and a prebuilt
   binary for linux can be found on
   https://github.com/google/autofdo/releases/tag/v0.30.1 (can also build
   from source).

   "<propeller_profile_prefix>" can be something like
   "/home/user/dir/any_string".

   This command generates a pair of Propeller profiles:
   "<propeller_profile_prefix>_cc_profile.txt" and
   "<propeller_profile_prefix>_ld_profile.txt".

6) Rebuild the kernel using the AutoFDO and Propeller profile files.
      CONFIG_AUTOFDO_CLANG=y
      CONFIG_PROPELLER_CLANG=y
   and
      $ make LLVM=1 CLANG_AUTOFDO_PROFILE=<autofdo_profile> \
        CLANG_PROPELLER_PROFILE_PREFIX=<propeller_profile_prefix>

798bb342e0 Rust changes for v6.13 
Toolchain and infrastructure:
 
  - Enable a series of lints, including safety-related ones, e.g. the
    compiler will now warn about missing safety comments, as well as
    unnecessary ones. How safety documentation is organized is a frequent
    source of review comments, thus having the compiler guide new
    developers on where they are expected (and where not) is very nice.
 
  - Start using '#[expect]': an interesting feature in Rust (stabilized
    in 1.81.0) that makes the compiler warn if an expected warning was
    _not_ emitted. This is useful to avoid forgetting cleaning up locally
    ignored diagnostics ('#[allow]'s).
 
  - Introduce '.clippy.toml' configuration file for Clippy, the Rust
    linter, which will allow us to tweak its behaviour. For instance, our
    first use cases are declaring a disallowed macro and, more
    importantly, enabling the checking of private items.
 
  - Lints-related fixes and cleanups related to the items above.
 
  - Migrate from 'receiver_trait' to 'arbitrary_self_types': to get the
    kernel into stable Rust, one of the major pieces of the puzzle is the
    support to write custom types that can be used as 'self', i.e. as
    receivers, since the kernel needs to write types such as 'Arc' that
    common userspace Rust would not. 'arbitrary_self_types' has been
    accepted to become stable, and this is one of the steps required to
    get there.
 
  - Remove usage of the 'new_uninit' unstable feature.
 
  - Use custom C FFI types. Includes a new 'ffi' crate to contain our
    custom mapping, instead of using the standard library 'core::ffi'
    one. The actual remapping will be introduced in a later cycle.
 
  - Map '__kernel_{size_t,ssize_t,ptrdiff_t}' to 'usize'/'isize' instead
    of 32/64-bit integers.
 
  - Fix 'size_t' in bindgen generated prototypes of C builtins.
 
  - Warn on bindgen < 0.69.5 and libclang >= 19.1 due to a double issue
    in the projects, which we managed to trigger with the upcoming
    tracepoint support. It includes a build test since some distributions
    backported the fix (e.g. Debian -- thanks!). All major distributions
    we list should be now OK except Ubuntu non-LTS.
 
 'macros' crate:
 
  - Adapt the build system to be able run the doctests there too; and
    clean up and enable the corresponding doctests.
 
 'kernel' crate:
 
  - Add 'alloc' module with generic kernel allocator support and remove
    the dependency on the Rust standard library 'alloc' and the extension
    traits we used to provide fallible methods with flags.
 
    Add the 'Allocator' trait and its implementations '{K,V,KV}malloc'.
    Add the 'Box' type (a heap allocation for a single value of type 'T'
    that is also generic over an allocator and considers the kernel's GFP
    flags) and its shorthand aliases '{K,V,KV}Box'. Add 'ArrayLayout'
    type. Add 'Vec' (a contiguous growable array type) and its shorthand
    aliases '{K,V,KV}Vec', including iterator support.
 
    For instance, now we may write code such as:
 
        let mut v = KVec::new();
        v.push(1, GFP_KERNEL)?;
        assert_eq!(&v, &[1]);
 
    Treewide, move as well old users to these new types.
 
  - 'sync' module: add global lock support, including the
    'GlobalLockBackend' trait; the 'Global{Lock,Guard,LockedBy}' types
     and the 'global_lock!' macro. Add the 'Lock::try_lock' method.
 
  - 'error' module: optimize 'Error' type to use 'NonZeroI32' and make
    conversion functions public.
 
  - 'page' module: add 'page_align' function.
 
  - Add 'transmute' module with the existing 'FromBytes' and 'AsBytes'
    traits.
 
  - 'block::mq::request' module: improve rendered documentation.
 
  - 'types' module: extend 'Opaque' type documentation and add simple
    examples for the 'Either' types.
 
 drm/panic:
 
  - Clean up a series of Clippy warnings.
 
 Documentation:
 
  - Add coding guidelines for lints and the '#[expect]' feature.
 
  - Add Ubuntu to the list of distributions in the Quick Start guide.
 
 MAINTAINERS:
  - Add Danilo Krummrich as maintainer of the new 'alloc' module.
 
 And a few other small cleanups and fixes.

445d9f05fa NFSD 6.13 Release Notes 
Jeff Layton contributed a scalability improvement to NFSD's NFSv4
 backchannel session implementation. This improvement is intended to
 increase the rate at which NFSD can safely recall NFSv4 delegations
 from clients, to avoid the need to revoke them. Revoking requires
 a slow state recovery process.
 
 A wide variety of bug fixes and other incremental improvements make
 up the bulk of commits in this series. As always I am grateful to
 the NFSD contributors, reviewers, testers, and bug reporters who
 participated during this cycle.

70dbb12e95 i2c-for-6.13-part2 
Andi was super busy the last weeks, so this pull requests contains one
 series (nomadik) and a number of smaller additions which were ready to
 go but nearly overlooked. Despite the late collection, they have been
 properly reviewed and have been in -next for 6 days now in Andi's tree.
 
 New feature support:
  - Added support for frequencies up to 3.4 MHz on Nomadik I2C.
  - DesignWare now accounts for bus capacitance and clock
    optimisation (declared as new parameters in the binding) to
    improve the calculation of signal rise and fall times
    (t_high and t_low).
 
 New Hardware support:
  - DWAPB I2C controller on FUJITSU-MONAKA (new ACPI HID).
  - Allwinner A523 (new compatible ID).
  - Mobileye EyeQ6H (new compatible ID).

5d4d263e1c mailbox: Introduce support for T-head TH1520 Mailbox driver 
This driver was tested using the drm/imagination GPU driver. It was able
to successfully power on the GPU, by passing a command through mailbox
from E910 core to E902 that's responsible for powering up the GPU. The
GPU driver was able to read the BVNC version from control registers,
which confirms it was successfully powered on.

[   33.957467] powervr ffef400000.gpu: [drm] loaded firmware
powervr/rogue_36.52.104.182_v1.fw
[   33.966008] powervr ffef400000.gpu: [drm] FW version v1.0 (build
6621747 OS)
[   38.978542] powervr ffef400000.gpu: [drm] *ERROR* Firmware failed to
boot

Though the driver still fails to boot the firmware, the mailbox driver
works when used with the not-yet-upstreamed firmware AON driver. There
is ongoing work to get the BXM-4-64 supported with the drm/imagination
driver [1], though it's not completed yet.

This work is based on the driver from the vendor kernel [2].

980f8f8fd4 Summary 
* sysctl ctl_table constification
 
   Constifying ctl_table structs prevents the modification of proc_handler
   function pointers. All ctl_table struct arguments are const qualified in the
   sysctl API in such a way that the ctl_table arrays being defined elsewhere
   and passed through sysctl can be constified one-by-one. We kick the
   constification off by qualifying user_table in kernel/ucount.c and expect all
   the ctl_tables to be constified in the coming releases.
 
 * Misc fixes
 
   Adjust comments in two places to better reflect the code. Remove superfluous
   dput calls. Remove Luis from sysctl maintainership. Replace comments about
   holding a lock with calls to lockdep_assert_held.
 
 * Testing
 
   All these went through 0-day and they have all been in linux-next for at
   least 1 month (since Oct-24). I also rand these through the sysctl selftest
   for x86_64.

d0c9a21c8e MTD device changes: Aside from the platform_driver::remove() switch, two 
misc issues got fixed.
 
 SPI-NAND changes:
 A load of fixes to Winbond manufacturer driver have been done, plus a
 structure constification.
 
 Raw NAND changes:
 The GPMI driver has been improved on the power management side.
 The Davinci driver has been cleaned up.
 A leak in the Atmel driver plus some typos in the core have been fixed.
 
 SPI NOR changes:
 Introduce byte swap support for 8D-8D-8D mode and a user for it:
 macronix. SPI NOR flashes may swap the bytes on a 16-bit boundary when
 configured in Octal DTR mode. For such cases the byte order is
 propagated through SPI MEM to the SPI controllers so that the
 controllers swap the bytes back at runtime. This avoids breaking the
 boot sequence because of the endianness problems that appear when the
 bootloaders use 1-1-1 and the kernel uses 8D-8D-8D with byte swap
 support. Along with the SPI MEM byte swap support we queue a patch for
 the SPI MXIC controller that swaps the bytes back at runtime.

9f3a2ba62c The core framework gained a clk provider helper, a clk consumer helper, and 
some unit tests for the assigned clk rates feature in DeviceTree. On the vendor
 driver side, we gained a whole pile of SoC driver support detailed below. The
 majority in the diffstat is Qualcomm, but there's also quite a few Samsung and
 Mediatek clk driver additions in here as well. The top vendors is quite common,
 but the sheer amount of new drivers is uncommon, so I'm anticipating a larger
 number of fixes for clk drivers this cycle.
 
 Core:
  - devm_clk_bulk_get_all_enabled() to return number of clks acquired
  - devm_clk_hw_register_gate_parent_hw() helper to modernize drivers
  - KUnit tests for clk-assigned-rates{,-u64}
 
 New Drivers:
  - Marvell PXA1908 SoC clks
  - Mobileye EyeQ5, EyeQ6L and EyeQ6H clk driver
  - TWL6030 clk driver
  - Nuvoton Arbel BMC NPCM8XX SoC clks
  - MediaTek MT6735 SoC clks
  - MediaTek MT7620, MT7628 and MT7688 MMC clks
  - Add a driver for gated fixed rate clocks
  - Global clock controllers for Qualcomm QCS8300 and IPQ5424 SoCs
  - Camera, display and video clock controllers for Qualcomm SA8775P SoCs
  - Global, display, GPU, TCSR, and RPMh clock controllers for Qualcomm SAR2130P
  - Global, camera, display, GPU, and video clock controllers for Qualcomm
    SM8475 SoCs
  - RTC power domain and Battery Backup Function (VBATTB) clock support for the
    Renesas RZ/G3S SoC
  - Qualcomm IPQ9574 alpha PLLs
  - Support for i.MX91 CCM in the i.MX93 driver
  - Microchip LAN969X SoC clks
  - Cortex-A55 core clocks and Interrupt Control Unit (ICU) clock and reset on
    Renesas RZ/V2H(P)
  - Samsung ExynosAutov920 clk drivers for PERIC1, MISC, HSI0 and HSI1
  - Samsung Exynos8895 clk drivers for FSYS0/1, PERIC0/1, PERIS and TOP
 
 Updates:
  - Convert more clk bindings to YAML
  - Various clk driver cleanups: NULL checks, add const, etc.
  - Remove END/NUM #defines that count number of clks in various binding headers
  - Continue moving reset drivers to drivers/reset via auxiliary bus

   for consistent register map configuration across syscons of all sizes.
 
 - New device support has been added for QCS8300, qcs615, SA8255p, and
   samsung,s2dos05, expanding the range of compatible hardware.
 
 - The cros_ec driver now supports loading cros_ec_ucsi on supported ECs
   and avoids loading the charger with UCSI, streamlining functionality.
 
 - The bd96801 driver now utilizes the more modern maple tree register
   cache, improving performance.
 
 - The da9052-spi driver has undergone a fix to change the read-mask to
   write-mask, preventing potential issues.
 
 - Unused declarations in max77693 have been removed, and support for
   samsung,s2dos05 has been added, enhancing code clarity and device compatibility.
 
 - Error handling in cs42l43 has been fixed to avoid unbalanced regulator
   put and ensure proper synchronization during driver removal.
 
 - The wcd934x driver now uses MODULE_DEVICE_TABLE() instead of
   MODULE_ALIAS(), improving code consistency.
 
 - Documentation for qcom,tcsr, syscon, and atmel-smc has been updated
   and reorganized for better clarity and maintainability.
 
 - The intel_soc_pmic_bxtwc driver has undergone significant improvements,
   including the use of IRQ domains for various devices, fixing IRQ domain names
   duplication, and code refactoring for better consistency and maintainability.

fcc79e1714 Networking changes for 6.13. 
The most significant set of changes is the per netns RTNL. The new
 behavior is disabled by default, regression risk should be contained.
 
 Notably the new config knob PTP_1588_CLOCK_VMCLOCK will inherit its
 default value from PTP_1588_CLOCK_KVM, as the first is intended to be
 a more reliable replacement for the latter.
 
 Core
 ----
 
  - Started a very large, in-progress, effort to make the RTNL lock
    scope per network-namespace, thus reducing the lock contention
    significantly in the containerized use-case, comprising:
    - RCU-ified some relevant slices of the FIB control path
    - introduce basic per netns locking helpers
    - namespacified the IPv4 address hash table
    - remove rtnl_register{,_module}() in favour of rtnl_register_many()
    - refactor rtnl_{new,del,set}link() moving as much validation as
      possible out of RTNL lock
    - convert all phonet doit() and dumpit() handlers to RCU
    - convert IPv4 addresses manipulation to per-netns RTNL
    - convert virtual interface creation to per-netns RTNL
    the per-netns lock infra is guarded by the CONFIG_DEBUG_NET_SMALL_RTNL
    knob, disabled by default ad interim.
 
  - Introduce NAPI suspension, to efficiently switching between busy
    polling (NAPI processing suspended) and normal processing.
 
  - Migrate the IPv4 routing input, output and control path from direct
    ToS usage to DSCP macros. This is a work in progress to make ECN
    handling consistent and reliable.
 
  - Add drop reasons support to the IPv4 rotue input path, allowing
    better introspection in case of packets drop.
 
  - Make FIB seqnum lockless, dropping RTNL protection for read
    access.
 
  - Make inet{,v6} addresses hashing less predicable.
 
  - Allow providing timestamp OPT_ID via cmsg, to correlate TX packets
    and timestamps
 
 Things we sprinkled into general kernel code
 --------------------------------------------
 
  - Add small file operations for debugfs, to reduce the struct ops size.
 
  - Refactoring and optimization for the implementation of page_frag API,
    This is a preparatory work to consolidate the page_frag
    implementation.
 
 Netfilter
 ---------
 
  - Optimize set element transactions to reduce memory consumption
 
  - Extended netlink error reporting for attribute parser failure.
 
  - Make legacy xtables configs user selectable, giving users
    the option to configure iptables without enabling any other config.
 
  - Address a lot of false-positive RCU issues, pointed by recent
    CI improvements.
 
 BPF
 ---
 
  - Put xsk sockets on a struct diet and add various cleanups. Overall,
    this helps to bump performance by 12% for some workloads.
 
  - Extend BPF selftests to increase coverage of XDP features in
    combination with BPF cpumap.
 
  - Optimize and homogenize bpf_csum_diff helper for all archs and also
    add a batch of new BPF selftests for it.
 
  - Extend netkit with an option to delegate skb->{mark,priority}
    scrubbing to its BPF program.
 
  - Make the bpf_get_netns_cookie() helper available also to tc(x) BPF
    programs.
 
 Protocols
 ---------
 
  - Introduces 4-tuple hash for connected udp sockets, speeding-up
    significantly connected sockets lookup.
 
  - Add a fastpath for some TCP timers that usually expires after close,
    the socket lock contention.
 
  - Add inbound and outbound xfrm state caches to speed up state lookups.
 
  - Avoid sending MPTCP advertisements on stale subflows, reducing
    risks on loosing them.
 
  - Make neighbours table flushing more scalable, maintaining per device
    neigh lists.
 
 Driver API
 ----------
 
  - Introduce a unified interface to configure transmission H/W shaping,
    and expose it to user-space via generic-netlink.
 
  - Add support for per-NAPI config via netlink. This makes napi
    configuration persistent across queues removal and re-creation.
    Requires driver updates, currently supported drivers are:
    nVidia/Mellanox mlx4 and mlx5, Broadcom brcm and Intel ice.
 
  - Add ethtool support for writing SFP / PHY firmware blocks.
 
  - Track RSS context allocation from ethtool core.
 
  - Implement support for mirroring to DSA CPU port, via TC mirror
    offload.
 
  - Consolidate FDB updates notification, to avoid duplicates on
    device-specific entries.
 
  - Expose DPLL clock quality level to the user-space.
 
  - Support master-slave PHY config via device tree.
 
 Tests and tooling
 -----------------
 
  - forwarding: introduce deferred commands, to simplify
    the cleanup phase
 
 Drivers
 -------
 
  - Updated several drivers - Amazon vNic, Google vNic, Microsoft vNic,
    Intel e1000e and Broadcom Tigon3 - to use netdev-genl to link the
    IRQs and queues to NAPI IDs, allowing busy polling and better

PCI/pwrctrl: Rename pwrctl files to pwrctrl 
To slightly reduce confusion between "pwrctl" (the power controller and
power sequencing framework) and "bwctrl" (the bandwidth controller),
rename "pwrctl" to "pwrctrl" so they use the same "ctrl" suffix.

Rename drivers/pci/pwrctl/ to drivers/pci/pwrctrl/, including the related
MAINTAINERS, include file (include/linux/pci-pwrctl.h), Makefile, and
Kconfig changes.

This is the minimal rename of files only.  A subsequent commit will rename
functions and data structures.
