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

ceb8bf2cea module: Convert default symbol namespace to string literal 
Commit cdd30ebb1b ("module: Convert symbol namespace to string
literal") only converted MODULE_IMPORT_NS() and EXPORT_SYMBOL_NS(),
leaving DEFAULT_SYMBOL_NAMESPACE as a macro expansion.

This commit converts DEFAULT_SYMBOL_NAMESPACE in the same way to avoid
annoyance for the default namespace as well.

f00582aa4a dt-bindings: power: mediatek: Add another nested power-domain layer 
The MT8188 SoC has a more in-depth power-domain tree, and the
CHECK_DTBS=y check could fail because the current MediaTek power
dt-binding is insufficient to cover its CAM_SUBA and CAM_SUBB
sub-domains.

Add one more nested power-domain layer to pass the check.

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

Pull char/misc/IIO/whatever driver subsystem updates from Greg KH:
 "Here is the 'big and hairy' char/misc/iio and other small driver
  subsystem updates for 6.13-rc1.

  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

55cb93fd24 Driver core changes for 6.13-rc1 
Here is a small set of driver core changes for 6.13-rc1.
 
 Nothing major for this merge cycle, except for the 2 simple merge
 conflicts are here just to make life interesting.
 
 Included in here are:
   - sysfs core changes and preparations for more sysfs api cleanups that
     can come through all driver trees after -rc1 is out
   - fw_devlink fixes based on many reports and debugging sessions
   - list_for_each_reverse() removal, no one was using it!
   - last-minute seq_printf() format string bug found and fixed in many
     drivers all at once.
   - minor bugfixes and changes full details in the shortlog
 
 As mentioned above, there is 2 merge conflicts with your tree, one is
 where the file is removed (easy enough to resolve), the second is a
 build time error, that has been found in linux-next and the fix can be
 seen here:
 	https://lore.kernel.org/r/20241107212645.41252436@canb.auug.org.au
 
 Other than that, the changes here have been in linux-next with no other
 reported issues.

7af08b57bc Tracing updates for 6.13: 
- Add trace flag for NEED_RESCHED_LAZY
 
   Now that NEED_RESCHED_LAZY is upstream, add it to the status bits of the
   common_flags. This will now show when the NEED_RESCHED_LAZY flag is set that
   is used for debugging latency issues in the kernel via a trace.
 
 - Remove leftover "__idx" variable when SRCU was removed from the tracepoint
   code
 
 - Add rcu_tasks_trace guard
 
   To add a guard() around the tracepoint code, a rcu_tasks_trace guard needs
   to be created first.
 
 - Remove __DO_TRACE() macro and just call __DO_TRACE_CALL() directly
 
   The DO_TRACE() macro has conditional locking depending on what was passed
   into the macro parameters. As the guts of the macro has been moved to
   __DO_TRACE_CALL() to handle static call logic, there's no reason to keep
   the __DO_TRACE() macro around. It is better to just do the locking in
   place without the conditionals and call __DO_TRACE_CALL() from those
   locations. The "cond" passed in can also be moved out of that macro.
   This simplifies the code.
 
 - Remove the "cond" from the system call tracepoint macros
 
   The "cond" variable was added to allow some tracepoints to check a
   condition within the static_branch (jump/nop) logic. The system calls do
   not need this. Removing it simplifies the code.
 
 - Replace scoped_guard() with just guard() in the tracepoint logic
 
   guard() works just as well as scoped_guard() in the tracepoint logic and
   the scoped_guard() causes some issues.

8cd07cc6c8 kbuild: allow to start building external modules in any directory 
Unless an explicit O= option is provided, external module builds must
start from the kernel directory.

This can be achieved by using the -C option:

  $ make -C /path/to/kernel M=/path/to/external/module

This commit allows starting external module builds from any directory,
so you can also do the following:

  $ make -f /path/to/kernel/Makefile M=/path/to/external/module

The key difference is that the -C option changes the working directory
and parses the Makefile located there, while the -f option only
specifies the Makefile to use.

As shown in the examples in Documentation/kbuild/modules.rst, external
modules usually have a wrapper Makefile that allows you to build them
without specifying any make arguments. The Makefile typically contains
a rule as follows:

    KDIR ?= /path/to/kernel
    default:
            $(MAKE) -C $(KDIR) M=$(CURDIR) $(MAKECMDGOALS)

The log will appear as follows:

    $ make
    make -C /path/to/kernel M=/path/to/external/module
    make[1]: Entering directory '/path/to/kernel'
    make[2]: Entering directory '/path/to/external/module'
      CC [M]  helloworld.o
      MODPOST Module.symvers
      CC [M]  helloworld.mod.o
      CC [M]  .module-common.o
      LD [M]  helloworld.ko
    make[2]: Leaving directory '/path/to/external/module'
    make[1]: Leaving directory '/path/to/kernel'

This changes the working directory twice because the -C option first
switches to the kernel directory, and then Kbuild internally recurses
back to the external module directory.

With this commit, the wrapper Makefile can directly include the kernel
Makefile:

    KDIR ?= /path/to/kernel
    export KBUILD_EXTMOD := $(realpath $(dir $(lastword $(MAKEFILE_LIST))))
    include $(KDIR)/Makefile

This avoids unnecessary sub-make invocations:

    $ make
      CC [M]  helloworld.o
      MODPOST Module.symvers
      CC [M]  helloworld.mod.o
      CC [M]  .module-common.o
      LD [M]  helloworld.ko

11b3d5175e kbuild: support building external modules in a separate build directory 
There has been a long-standing request to support building external
modules in a separate build directory.

This commit introduces a new environment variable, KBUILD_EXTMOD_OUTPUT,
and its shorthand Make variable, MO.

A simple usage:

 $ make -C <kernel-dir> M=<module-src-dir> MO=<module-build-dir>

13b25489b6 kbuild: change working directory to external module directory with M= 
Currently, Kbuild always operates in the output directory of the kernel,
even when building external modules. This increases the risk of external
module Makefiles attempting to write to the kernel directory.

This commit switches the working directory to the external module
directory, allowing the removal of the $(KBUILD_EXTMOD)/ prefix from
some build artifacts.

The command for building external modules maintains backward
compatibility, but Makefiles that rely on working in the kernel
directory may break. In such cases, $(objtree) and $(srctree) should
be used to refer to the output and source directories of the kernel.

The appearance of the build log will change as follows:

[Before]

  $ make -C /path/to/my/linux M=/path/to/my/externel/module
  make: Entering directory '/path/to/my/linux'
    CC [M]  /path/to/my/externel/module/helloworld.o
    MODPOST /path/to/my/externel/module/Module.symvers
    CC [M]  /path/to/my/externel/module/helloworld.mod.o
    CC [M]  /path/to/my/externel/module/.module-common.o
    LD [M]  /path/to/my/externel/module/helloworld.ko
  make: Leaving directory '/path/to/my/linux'

[After]

  $ make -C /path/to/my/linux M=/path/to/my/externel/module
  make: Entering directory '/path/to/my/linux'
  make[1]: Entering directory '/path/to/my/externel/module'
    CC [M]  helloworld.o
    MODPOST Module.symvers
    CC [M]  helloworld.mod.o
    CC [M]  .module-common.o
    LD [M]  helloworld.ko
  make[1]: Leaving directory '/path/to/my/externel/module'
  make: Leaving directory '/path/to/my/linux'

Printing "Entering directory" twice is cumbersome. This will be
addressed later.

After the deprecation of CONFIG_DEFAULT_SECURITY, it is no longer used
to enable and configure AppArmor. Since kernel 5.0,
`CONFIG_SECURITY_APPARMOR_BOOTPARAM_VALUE` is not used either.
Instead, the CONFIG_LSM parameter manages the order and selection of LSMs.

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)

   - 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

     controller configuration (Damien Le Moal)

   - Attempt link training at 5 GT/s when both partners support it

   - 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

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>

Linus Torvalds
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.
