The current logic to split the 64-bit argument into its 32-bit halves is
byte-order specific and a bit clunky. Use a union instead which is
easier to read and works in all cases.
GCC still generates the same machine code.
While at it, rename the arguments of the __memset64() prototype to
actually reflect their semantics.

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"

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.

forced interrupt threading is enabled.
- Remove stub primary (hard interrupt) handlers

"Scheduler Kconfig space updates:
- Further consolidate configurable preemption modes (Peter Zijlstra)
Reduce the number of architectures that are allowed to offer

None and voluntary are only available as legacy features on

"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)

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.

Pull vfs initrd removal from Christian Brauner:
"Remove the deprecated linuxrc-based initrd code path and related dead
code. The linuxrc initrd path was deprecated in 2020 and this series
completes its removal. If we see real-life regressions we'll revert.
The core change removes handle_initrd() and init_linuxrc() — the
entire flow that ran /linuxrc from an initrd, pivoted roots, and
handed off to the real root filesystem. With that gone, initrd_load()
becomes void (no longer short-circuits prepare_namespace()),
rd_load_image() is simplified to always load /initrd.image instead of
taking a path, and rd_load_disk() is deleted.
The /proc/sys/kernel/real-root-dev sysctl and its backing variable are
removed since they only existed for linuxrc to communicate the real
root device back to the kernel.
The no-op load_ramdisk= and prompt_ramdisk= parameters are dropped,
and noinitrd and ramdisk_start= gain deprecation warnings.
Initramfs is entirely unaffected. The non-linuxrc initrd path
(root=/dev/ram0) is preserved but now carries a deprecation warning

Since multi_v7_defconfig is meant to be the generic defconfig, many
users are not going to be experts and it is counterintuitive to have
CONFIG_EXPERT enabled.
This change has a couple of side-effects:
- CONFIG_NAMESPACES is enabled by default. This adds about 0.2% of
.text, but is already enabled in many board specific configs, and
apparently a requirement for systemd, so this seems like a useful
change.
- CONFIG_DEBUG_MEMORY_INIT is enabled now, adding a tiny bit
of code in the inittext section
- CONFIG_RFKILL, CONFIG_MEDIA_SUPPORT_FILTER and various CONFIG_HID
driver defaults change, so these have to be listed explicitly to
maintain the previous behavior
- CONFIG_SERIAL_SH_SCI_NR_UARTS=20 changes to the default value
of 18, which I understand to be sufficient for any buard, even
if all UARTS are enabled at the same time

Minor improvements in ARM64 DTS for v6.20
Several minor cleanups for Nuvoton, LG, Spreadtrum, Toshiba, Cavium, ARM
and APM SoCs:
1. Switch to recommended node names by fixing style
(s/lowercase/hyphen/), using generic naming and adhering to DT
bindings.
2. Use consistent whitespaces around.
3. Add missing properties like UART clocks (Cavium Thunder 88xx) or
"reg" (APM).
4. Drop incorrect or long time deprecated propeties.
5. Correct clock cells to 0 for fixed-factor-clock clocks.
