5991bfa3f8 block: fix folio leak in bio_iov_iter_bounce_read()
If iov_iter_extract_bvecs() returns an error or zero bytes extracted,
then the folio allocated is leaked on return. Ensure it's put before
returning.

5b88af7113 block: allow IOC_PR_READ_* ioctls with BLK_OPEN_READ
The recently added IOC_PR_READ_* ioctls require the same BLK_OPEN_WRITE
permission as the older persistent reservation ioctls. This has the
drawback that udev triggers when the file descriptor is closed,
resulting in unnecessary activity like scanning partitions even though
these read-only ioctls do not modify the device.

Change IOC_PR_READ_KEYS and IOC_PR_READ_RESERVATION to require
BLK_OPEN_READ. This prevents unnecessary activity every time `blkpr
--read-keys` or `blkpr --read-reservation` is invoked by shell scripts,
for example.

It is safe to reduce the permission requirement from BLK_OPEN_WRITE to
BLK_OPEN_READ since these two ioctls do not modify the persistent
reservation state. Userspace cannot use the information fetched by these
ioctls to make changes to the device unless it later opens the device
with BLK_OPEN_WRITE.

Fixes: 3e2cb9ee76 ("block: add IOC_PR_READ_RESERVATION ioctl")
Fixes: 22a1ffea5f ("block: add IOC_PR_READ_KEYS ioctl")

2ebc8d600f drbd: always set BLK_FEAT_STABLE_WRITES
DRBD requires stable pages because it may read the same bio data
multiple times for local disk I/O and network transmission, and in
some cases for calculating checksums.

The BLK_FEAT_STABLE_WRITES flag is set when the device is first
created, but blk_set_stacking_limits() clears it whenever a
backing device is attached. In some cases the flag may be
inherited from the backing device, but we want it to be enabled
at all times.

Unconditionally re-enable BLK_FEAT_STABLE_WRITES in
drbd_reconsider_queue_parameters() after the queue parameter
negotiations.

Also, document why we want this flag enabled in the first place.

Fixes: 1a02f3a73f ("block: move the stable_writes flag to queue_limits")

6589b3d76d Merge tag 'soc-dt-7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull SoC devicetree updates from Arnd Bergmann:
 "There are a handful of new SoCs this time, all of these are more or
  less related to chips in a wider family:

   - SpacemiT Key Stone K3 is an 8-core risc-v chip, and the first
     widely available RVA23 implementation. Note that this is entirely
     unrelated with the similarly named Texas Instruments K3 chip family
     that follwed the TI Keystone2 SoC.

   - The Realtek Kent family of SoCs contains three chip models
     rtd1501s, rtd1861b and rtd1920s, and is related to their earlier
     Set-top-box and NAS products such as rtd1619, but is built on newer
     Arm Cortex-A78 cores.

   - The Qualcomm Milos family includes the Snapdragon 7s Gen 3 (SM7635)
     mobile phone SoC built around Armv9 Kryo cores of the Arm
     Cortex-A720 generation. This one is used in the Fairphone Gen 6

   - Qualcomm Kaanapali is a new SoC based around eight high performance
     Oryon CPU cores

   - NXP i.MX8QP and i.MX952 are both feature reduced versions of chips
     we already support, i.e. the i.MX8QM and i.MX952, with fewer CPU
     cores and I/O interfaces.

  As part of a cleanup, a number of SoC specific devicetree files got
  removed because they did not have a single board using the .dtsi files
  and they were never compile tested as a result: Samsung s3c6400, ST
  spear320s, ST stm32mp21xc/stm32mp23xc/stm32mp25xc, Renesas
  r8a779m0/r8a779m2/r8a779m4/r8a779m6/r8a779m7/r8a779m8/r8a779mb/
  r9a07g044c1/r9a07g044l1/r9a07g054l1/r9a09g047e37, and TI
  am3703/am3715. All of these could be restored easily if a new board
  gets merged.

  Broadcom/Cavium/Marvell ThunderX2 gets removed along with its only
  machine, as all remaining users are assumed to be using ACPI based
  firmware.

  A relatively small number of 43 boards get added this time, and almost
  all of them for arm64. Aside from the reference boards for the newly
  added SoCs, this includes:

   - Three server boards use 32-bit ASpeed BMCs

   - One more reference board for 32-bit Microchip LAN9668

   - 64-bit Arm single-board computers based on Amlogic s905y4, CIX
     sky1, NXP ls1028a/imx8mn/imx8mp/imx91/imx93/imx95, Qualcomm
     qcs6490/qrb2210 and Rockchip rk3568/rk3588s

   - Carrier board for SOMs using Intel agilex5, Marvell Armada 7020,
     NXP iMX8QP, Mediatek mt8370/mt8390 and rockchip rk3588

   - Two mobile phones using Snapdragon 845

   - A gaming device and a NAS box, both based on Rockchips rk356x

  On top of the newly added boards and SoCs, there is a lot of
  background activity going into cleanups, in particular towards getting
  a warning-free dtc build, and the usual work on adding support for
  more hardware on the previously added machines"

1ca28333e4 x86: keep legacy generated vdso files around in .gitignore file
Commit 93d73005bf ("x86/entry/vdso: Rename vdso_image_* to
vdso*_image") updated the vdso .gitignore file with the new filenames,
which is certainly not incorrect.

However, while adding new generated names is obviously the right thing
to do, you should *not* immediately remove the old filenames from the
.gitignore file when things move around or get renamed, because people
still have those old generated files in their build trees - and they
haven't suddenly become valid files to commit to the repository just
because they were moved or renamed.

While it's mostly just a slight visual nuisance for 'git status' that
can be fixed up with a clean build tree, it can become more serious than
that: see for example commit 04a3389b35 ("Remove stale generated
'genheaders' file").

That commit removed up a stale generated file that had been carelessly
committed by a kernel developer because it wasn't properly ignored any
more and thus showed up as a new file in their tree.

Pull VDSO updates from Thomas Gleixner:

 - Provide the missing 64-bit variant of clock_getres()

   This allows the extension of CONFIG_COMPAT_32BIT_TIME to the vDSO and
   finally the removal of 32-bit time types from the kernel and UAPI.

 - Remove the useless and broken getcpu_cache from the VDSO

   The intention was to provide a trivial way to retrieve the CPU number
   from the VDSO, but as the VDSO data is per process there is no way to
   make it work.

 - Switch get/put_unaligned() from packed struct to memcpy()

   The packed struct violates strict aliasing rules which requires to
   pass -fno-strict-aliasing to the compiler. As this are scalar values
   __builtin_memcpy() turns them into simple loads and stores

 - Use __typeof_unqual__() for __unqual_scalar_typeof()

   The get/put_unaligned() changes triggered a new sparse warning when
   __beNN types are used with get/put_unaligned() as sparse builds add a
   special 'bitwise' attribute to them which prevents sparse to evaluate
   the Generic in __unqual_scalar_typeof().

   Newer sparse versions support __typeof_unqual__() which avoids the
   problem, but requires a recent sparse install. So this adds a sanity
   check to sparse builds, which validates that sparse is available and
   capable of handling it.

 - Force inline __cvdso_clock_getres_common()

   Compilers sometimes un-inline agressively, which results in function
   call overhead and problems with automatic stack variable
   initialization.

   Interestingly enough the force inlining results in smaller code than
   the un-inlined variant produced by GCC when optimizing for size.

Pull MSI updates from Thomas Gleixner:
 "Updates for the [PCI] MSI subsystem:

   - Add interrupt redirection infrastructure

     Some PCI controllers use a single demultiplexing interrupt for the
     MSI interrupts of subordinate devices.

     This prevents setting the interrupt affinity of device interrupts,
     which causes device interrupts to be delivered to a single CPU.
     That obviously is counterproductive for multi-queue devices and
     interrupt balancing.

     To work around this limitation the new infrastructure installs a
     dummy irq_set_affinity() callback which captures the affinity mask
     and picks a redirection target CPU out of the mask.

     When the PCI controller demultiplexes the interrupts it invokes a
     new handling function in the core, which either runs the interrupt
     handler in the context of the target CPU or delegates it to
     irq_work on the target CPU.

   - Utilize the interrupt redirection mechanism in the PCI DWC host
     controller driver.

     This allows affinity control for the subordinate device MSI
     interrupts instead of being randomly executed on the CPU which runs
     the demultiplex handler.

   - Replace the binary 64-bit MSI flag with a DMA mask

     Some PCI devices have PCI_MSI_FLAGS_64BIT in the MSI capability,
     but implement less than 64 address bits. This breaks on platforms
     where such a device is assigned an MSI address higher than what's
     supported.

     With the binary 64-bit flag there is no other choice than disabling
     64-bit MSI support which leaves the device disfunctional.

     By using a DMA mask the address limit of a device can be described
     correctly which provides support for the above scenario.

   - Make use of the DMA mask based address limit in the hda/intel and
     radeon drivers to enable them on affected platforms

   - The usual small cleanups and improvements"

 "Scheduler Kconfig space updates:

   - Further consolidate configurable preemption modes (Peter Zijlstra)

     Reduce the number of architectures that are allowed to offer
     PREEMPT_NONE and PREEMPT_VOLUNTARY, reducing the number of
     preemption models from four to just two: 'full' and 'lazy' on
     up-to-date architectures (arm64, loongarch, powerpc, riscv, s390,
     x86).

     None and voluntary are only available as legacy features on
     platforms that don't implement lazy preemption yet, or which don't
     even support preemption.

     The goal is to eventually remove cond_resched() and voluntary
     preemption altogether.

  RSEQ based 'scheduler time slice extension' support (Thomas Gleixner
  and Peter Zijlstra):

  This allows a thread to request a time slice extension when it enters
  a critical section to avoid contention on a resource when the thread
  is scheduled out inside of the critical section.

   - Add fields and constants for time slice extension
   - Provide static branch for time slice extensions
   - Add statistics for time slice extensions
   - Add prctl() to enable time slice extensions
   - Implement sys_rseq_slice_yield()
   - Implement syscall entry work for time slice extensions
   - Implement time slice extension enforcement timer
   - Reset slice extension when scheduled
   - Implement rseq_grant_slice_extension()
   - entry: Hook up rseq time slice extension
   - selftests: Implement time slice extension test
   - Allow registering RSEQ with slice extension
   - Move slice_ext_nsec to debugfs
   - Lower default slice extension
   - selftests/rseq: Add rseq slice histogram script

  Scheduler performance/scalability improvements:

   - Update rq->avg_idle when a task is moved to an idle CPU, which
     improves the scalability of various workloads (Shubhang Kaushik)

   - Reorder fields in 'struct rq' for better caching (Blake Jones)

   - Fair scheduler SMP NOHZ balancing code speedups (Shrikanth Hegde):
      - Move checking for nohz cpus after time check
      - Change likelyhood of nohz.nr_cpus
      - Remove nohz.nr_cpus and use weight of cpumask instead

   - Avoid false sharing for sched_clock_irqtime (Wangyang Guo)

   - Cleanups (Yury Norov):
      - Drop useless cpumask_empty() in find_energy_efficient_cpu()
      - Simplify task_numa_find_cpu()
      - Use cpumask_weight_and() in sched_balance_find_dst_group()

  DL scheduler updates:

   - Add a deadline server for sched_ext tasks (by Andrea Righi and Joel
     Fernandes, with fixes by Peter Zijlstra)

  RT scheduler updates:

   - Skip currently executing CPU in rto_next_cpu() (Chen Jinghuang)

  Entry code updates and performance improvements (Jinjie Ruan)

  This is part of the scheduler tree in this cycle due to inter-
  dependencies with the RSEQ based time slice extension work:

    - Remove unused syscall argument from syscall_trace_enter()
    - Rework syscall_exit_to_user_mode_work() for architecture reuse
    - Add arch_ptrace_report_syscall_entry/exit()
    - Inline syscall_exit_work() and syscall_trace_enter()

  Scheduler core updates (Peter Zijlstra):

   - Rework sched_class::wakeup_preempt() and rq_modified_*()
   - Avoid rq->lock bouncing in sched_balance_newidle()
   - Rename rcu_dereference_check_sched_domain() =>
            rcu_dereference_sched_domain()
   - <linux/compiler_types.h>: Add the __signed_scalar_typeof() helper

  Fair scheduler updates/refactoring (Peter Zijlstra and Ingo Molnar):

   - Fold the sched_avg update
   - Change rcu_dereference_check_sched_domain() to rcu-sched
   - Switch to rcu_dereference_all()
   - Remove superfluous rcu_read_lock()
   - Limit hrtick work
   - Join two #ifdef CONFIG_FAIR_GROUP_SCHED blocks
   - Clean up comments in 'struct cfs_rq'
   - Separate se->vlag from se->vprot
   - Rename cfs_rq::avg_load to cfs_rq::sum_weight
   - Rename cfs_rq::avg_vruntime to ::sum_w_vruntime & helper functions
   - Introduce and use the vruntime_cmp() and vruntime_op() wrappers for
     wrapped-signed aritmetics
   - Sort out 'blocked_load*' namespace noise

  Scheduler debugging code updates:

   - Export hidden tracepoints to modules (Gabriele Monaco)

   - Convert copy_from_user() + kstrtouint() to kstrtouint_from_user()
     (Fushuai Wang)

   - Add assertions to QUEUE_CLASS (Peter Zijlstra)

   - hrtimer: Fix tracing oddity (Thomas Gleixner)

Pull locking updates from Ingo Molnar:
 "Lock debugging:

   - Implement compiler-driven static analysis locking context checking,
     using the upcoming Clang 22 compiler's context analysis features
     (Marco Elver)

     We removed Sparse context analysis support, because prior to
     removal even a defconfig kernel produced 1,700+ context tracking
     Sparse warnings, the overwhelming majority of which are false
     positives. On an allmodconfig kernel the number of false positive
     context tracking Sparse warnings grows to over 5,200... On the plus
     side of the balance actual locking bugs found by Sparse context
     analysis is also rather ... sparse: I found only 3 such commits in
     the last 3 years. So the rate of false positives and the
     maintenance overhead is rather high and there appears to be no
     active policy in place to achieve a zero-warnings baseline to move
     the annotations & fixers to developers who introduce new code.

     Clang context analysis is more complete and more aggressive in
     trying to find bugs, at least in principle. Plus it has a different
     model to enabling it: it's enabled subsystem by subsystem, which
     results in zero warnings on all relevant kernel builds (as far as
     our testing managed to cover it). Which allowed us to enable it by
     default, similar to other compiler warnings, with the expectation
     that there are no warnings going forward. This enforces a
     zero-warnings baseline on clang-22+ builds (Which are still limited
     in distribution, admittedly)

     Hopefully the Clang approach can lead to a more maintainable
     zero-warnings status quo and policy, with more and more subsystems
     and drivers enabling the feature. Context tracking can be enabled
     for all kernel code via WARN_CONTEXT_ANALYSIS_ALL=y (default
     disabled), but this will generate a lot of false positives.

     ( Having said that, Sparse support could still be added back,
       if anyone is interested - the removal patch is still
       relatively straightforward to revert at this stage. )

  Rust integration updates: (Alice Ryhl, Fujita Tomonori, Boqun Feng)

    - Add support for Atomic<i8/i16/bool> and replace most Rust native
      AtomicBool usages with Atomic<bool>

    - Clean up LockClassKey and improve its documentation

    - Add missing Send and Sync trait implementation for SetOnce

    - Make ARef Unpin as it is supposed to be

      helper LTO

    - Inline various lock related functions to avoid additional function
      calls

 "x86 PMU driver updates:

   - Add support for the core PMU for Intel Diamond Rapids (DMR) CPUs
     (Dapeng Mi)

     Compared to previous iterations of the Intel PMU code, there's been
     a lot of changes, which center around three main areas:

      - Introduce the OFF-MODULE RESPONSE (OMR) facility to replace the
        Off-Core Response (OCR) facility

      - New PEBS data source encoding layout

      - Support the new "RDPMC user disable" feature

   - Likewise, a large series adds uncore PMU support for Intel Diamond
     Rapids (DMR) CPUs (Zide Chen)

     This centers around these four main areas:

      - DMR may have two Integrated I/O and Memory Hub (IMH) dies,
        separate from the compute tile (CBB) dies. Each CBB and each IMH
        die has its own discovery domain.

      - Unlike prior CPUs that retrieve the global discovery table
        portal exclusively via PCI or MSR, DMR uses PCI for IMH PMON
        discovery and MSR for CBB PMON discovery.

      - DMR introduces several new PMON types: SCA, HAMVF, D2D_ULA, UBR,
        PCIE4, CRS, CPC, ITC, OTC, CMS, and PCIE6.

      - IIO free-running counters in DMR are MMIO-based, unlike SPR.

   - Also add support for Add missing PMON units for Intel Panther Lake,
     and support Nova Lake (NVL), which largely maps to Panther Lake.
     (Zide Chen)

   - KVM integration: Add support for mediated vPMUs (by Kan Liang and
     Sean Christopherson, with fixes and cleanups by Peter Zijlstra,
     Sandipan Das and Mingwei Zhang)

   - Add Intel cstate driver to support for Wildcat Lake (WCL) CPUs,
     which are a low-power variant of Panther Lake (Zide Chen)

   - Add core, cstate and MSR PMU support for the Airmont NP Intel CPU
     (aka MaxLinear Lightning Mountain), which maps to the existing
     Airmont code (Martin Schiller)

  Performance enhancements:

   - Speed up kexec shutdown by avoiding unnecessary cross CPU calls
     (Jan H. Schönherr)

   - Fix slow perf_event_task_exit() with LBR callstacks (Namhyung Kim)

  User-space stack unwinding support:

   - Various cleanups and refactorings in preparation to generalize the
     unwinding code for other architectures (Jens Remus)

  Uprobes updates:

   - Transition from kmap_atomic to kmap_local_page (Keke Ming)

   - Fix incorrect lockdep condition in filter_chain() (Breno Leitao)

   - Fix XOL allocation failure for 32-bit tasks (Oleg Nesterov)

  Misc fixes and cleanups:

   - s390: Remove kvm_types.h from Kbuild (Randy Dunlap)

 "Toolchain and infrastructure:

   - Add '__rust_helper' annotation to the C helpers

     This is needed to inline these helpers into Rust code

   - Remove imports available via the prelude, treewide

     This was possible thanks to a new lint in Klint that Gary has
     implemented -- more Klint-related changes, including initial
     upstream support, are coming

   - Deduplicate pin-init flags

  'kernel' crate:

   - Add support for calling a function exactly once with the new
     'do_once_lite!' macro (and 'OnceLite' type)

     Based on this, add 'pr_*_once!' macros to print only once

   - Add 'impl_flags!' macro for defining common bitflags operations:

         impl_flags!(
             /// Represents multiple permissions.
             #[derive(Debug, Clone, Default, Copy, PartialEq, Eq)]
             pub struct Permissions(u32);

             /// Represents a single permission.
             #[derive(Debug, Clone, Copy, PartialEq, Eq)]
             pub enum Permission {
                 /// Read permission.
                 Read = 1 << 0,

                 /// Write permission.
                 Write = 1 << 1,

                 /// Execute permission.
                 Execute = 1 << 2,
             }
         );

         let mut f: Permissions = Permission::Read | Permission::Write;
         assert!(f.contains(Permission::Read));
         assert!(!f.contains(Permission::Execute));

         f |= Permission::Execute;
         assert!(f.contains(Permission::Execute));

         let f2: Permissions = Permission::Write | Permission::Execute;
         assert!((f ^ f2).contains(Permission::Read));
         assert!(!(f ^ f2).contains(Permission::Write));

   - 'bug' module: support 'CONFIG_DEBUG_BUGVERBOSE_DETAILED' in the
     'warn_on!' macro in order to show the evaluated condition alongside
     the file path:

          ------------[ cut here ]------------
          WARNING: [val == 1] linux/samples/rust/rust_minimal.rs:27 at ...
          Modules linked in: rust_minimal(+)

   - Add safety module with 'unsafe_precondition_assert!' macro,
     currently a wrapper for 'debug_assert!', intended to mark the
     validation of safety preconditions where possible:

         /// # Safety
         ///
         /// The caller must ensure that `index` is less than `N`.
         unsafe fn set_unchecked(&mut self, index: usize, value: T) {
             unsafe_precondition_assert!(
                 index < N,
                 "set_unchecked() requires index ({index}) < N ({N})"
             );

             ...
         }

   - Add instructions to 'build_assert!' documentation requesting to
     always inline functions when used with function arguments

   - 'ptr' module: replace 'build_assert!' with a 'const' one

   - 'rbtree' module: reduce unsafe blocks on pointer derefs

   - 'transmute' module: implement 'FromBytes' and 'AsBytes' for
     inhabited ZSTs, and use it in Nova

   - More treewide replacements of 'c_str!' with C string literals

  'macros' crate:

   - Rewrite most procedural macros ('module!', 'concat_idents!',
     '#[export]', '#[vtable]', '#[kunit_tests]') to use the 'syn'
     parsing library which we introduced last cycle, with better
     diagnostics

     This also allows to support '#[cfg]' properly in the '#[vtable]'
     macro, to support arbitrary types in 'module!' macro (not just an
     identifier) and to remove several custom parsing helpers we had

   - Use 'quote!' from the recently vendored 'quote' library and remove
     our custom one

     The vendored one also allows us to avoid quoting '"' and '{}'
     inside the template anymore and editors can now highlight it. In
     addition, it improves robustness as it eliminates the need for
     string quoting and escaping

   - Use 'pin_init::zeroed()' to simplify KUnit code

  'pin-init' crate:

   - Rewrite all procedural macros ('[pin_]init!', '#[pin_data]',
     '#[pinned_drop]', 'derive([Maybe]Zeroable)') to use the 'syn'
     parsing library which we introduced last cycle, with better
     diagnostics

   - Implement 'InPlaceWrite' for '&'static mut MaybeUninit<T>'. This
     enables users to use external allocation mechanisms such as
     'static_cell'

   - Support tuple structs in 'derive([Maybe]Zeroable)'

   - Support attributes on fields in '[pin_]init!' (such as
     '#[cfg(...)]')

   - Add a '#[default_error(<type>)]' attribute to '[pin_]init!' to
     override the default error (when no '? Error' is specified)

   - Support packed structs in '[pin_]init!' with
     '#[disable_initialized_field_access]'

   - Remove 'try_[pin_]init!' in favor of merging their feature with
     '[pin_]init!'. Update the kernel's own 'try_[pin_]init!' macros to
     use the 'default_error' attribute

   - Correct 'T: Sized' bounds to 'T: ?Sized' in the generated
     'PinnedDrop' check by '#[pin_data]'

  Documentation:

   - Conclude the Rust experiment

  MAINTAINERS:

   - Add "RUST [RUST-ANALYZER]" entry for the rust-analyzer support.
     Tamir and Jesung will take care of it. They have both been active
     around it for a while. The new tree will flow through the Rust one

   - Add Gary as maintainer for "RUST [PIN-INIT]"

   - Update Boqun and Tamir emails to their kernel.org accounts

Pull module updates from Sami Tolvanen:
 "Module signing:

   - Remove SHA-1 support for signing modules.

     SHA-1 is no longer considered secure for signatures due to
     vulnerabilities that can lead to hash collisions. None of the major
     distributions use SHA-1 anymore, and the kernel has defaulted to
     SHA-512 since v6.11.

     Note that loading SHA-1 signed modules is still supported.

   - Update scripts/sign-file to use only the OpenSSL CMS API for
     signing.

     As SHA-1 support is gone, we can drop the legacy PKCS#7 API which
     was limited to SHA-1. This also cleans up support for legacy
     OpenSSL versions.

  Cleanups and fixes:

   - Use system_dfl_wq instead of the per-cpu system_wq following the
     ongoing workqueue API refactoring.

   - Avoid open-coded kvrealloc() in module decompression logic by using
     the standard helper.

   - Improve section annotations by replacing the custom __modinit with
     __init_or_module and removing several unused __INIT*_OR_MODULE
     macros.

   - Fix kernel-doc warnings in include/linux/moduleparam.h.

   - Ensure set_module_sig_enforced is only declared when module signing
     is enabled.

   - Fix gendwarfksyms build failures on 32-bit hosts.

958f7fb68c Merge tag 'kmalloc_obj-v7.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
Pull kmalloc_obj updates from Kees Cook:
 "Introduce the kmalloc_obj* family of APIs for switching to type-based
  kmalloc allocations, away from purely size-based allocations.
  Discussed on lkml, with you, and at Linux Plumbers. It's been in -next
  for the entire dev cycle.

  Before the merge window closes, I'd like to send the treewide
  change (generated from the Coccinelle script included here), which
  mechanically converts almost 20k callsites from kmalloc* to
  kmalloc_obj*:

   8007 files changed, 19980 insertions(+), 20838 deletions(-)

  This change needed fixes for mismatched types (since now the return
  type from allocations is a pointer to the requested type, not "void
  *"), and I've been fixing these over the last 4 releases.

  These fixes have mostly been trivial mismatches with const qualifiers
  or accidentally identical sizes (e.g. same object size: "struct kvec"
  vs "struct iovec", or differing pointers to pointers), but I did catch
  one case of too-small allocation.

  Summary:

   - Introduce kmalloc_obj*() family of type-based allocator APIs

   - checkpatch: Suggest kmalloc_obj family for sizeof allocations

   - coccinelle: Add kmalloc_objs conversion script"

Pull crypto library updates from Eric Biggers:

 - Add support for verifying ML-DSA signatures.

   ML-DSA (Module-Lattice-Based Digital Signature Algorithm) is a
   recently-standardized post-quantum (quantum-resistant) signature
   algorithm. It was known as Dilithium pre-standardization.

   The first use case in the kernel will be module signing. But there
   are also other users of RSA and ECDSA signatures in the kernel that
   might want to upgrade to ML-DSA eventually.

 - Improve the AES library:

     - Make the AES key expansion and single block encryption and
       decryption functions use the architecture-optimized AES code.
       Enable these optimizations by default.

     - Support preparing an AES key for encryption-only, using about
       half as much memory as a bidirectional key.

     - Replace the existing two generic implementations of AES with a
       single one.

 - Simplify how Adiantum message hashing is implemented. Remove the
   "nhpoly1305" crypto_shash in favor of direct lib/crypto/ support for
   NH hashing, and enable optimizations by default.
