The firmware drivers for ARM SCMI, FF-A and the Tee subsystem, as well
as the reset controller and cache controller subsystem all see small
bugfixes for reference ounting errors, ABI correctness, and NULL pointer
dereferences.
Similarly, there are multiple reference counting fixes in drivers/soc/
for vendor specific drivers (rockchips, microchip), while the freescale
drivers get a fix for a race condition and error handling.
The devicetree fixes for Rockchips and NXP got held up, so for the moment
there is only Renesas fixing problesm with SD card initialization, a
boot hang on one board and incorrect descriptions for interrupts and
clock registers on some SoCs. The Microchip polarfire gets a dts fix
for a boot time warning.
A defconfig fix avoids a warning about a conflicting assignment.

Commit 3e86e4d74c ("kbuild: keep .modinfo section in
vmlinux.unstripped") added .modinfo to ELF_DETAILS while removing it
from COMMON_DISCARDS, as it was needed in vmlinux.unstripped and
ELF_DETAILS was present in all architecture specific vmlinux linker
scripts. While this shuffle is fine for vmlinux, ELF_DETAILS and
COMMON_DISCARDS may be used by other linker scripts, such as the s390
and x86 compressed boot images, which may not expect to have a .modinfo
section. In certain circumstances, this could result in a bootloader
failing to load the compressed kernel [1].
Commit ddc6cbef3e ("s390/boot/vmlinux.lds.S: Ensure bzImage ends with
SecureBoot trailer") recently addressed this for the s390 bzImage but
the same bug remains for arm, parisc, and x86. The presence of .modinfo
in the x86 bzImage was the root cause of the issue worked around with
commit d50f210913 ("kbuild: align modinfo section for Secureboot
Authenticode EDK2 compat"). misc.c in arch/x86/boot/compressed includes
lib/decompress_unzstd.c, which in turn includes lib/xxhash.c and its
MODULE_LICENSE / MODULE_DESCRIPTION macros due to the STATIC definition.
Split .modinfo out from ELF_DETAILS into its own macro and handle it in
all vmlinux linker scripts. Discard .modinfo in the places where it was
previously being discarded from being in COMMON_DISCARDS, as it has
never been necessary in those uses.

This converts some of the visually simpler cases that have been split
over multiple lines. I only did the ones that are easy to verify the
resulting diff by having just that final GFP_KERNEL argument on the next
line.
Somebody should probably do a proper coccinelle script for this, but for
me the trivial script actually resulted in an assertion failure in the
middle of the script. I probably had made it a bit _too_ trivial.
So after fighting that far a while I decided to just do some of the
syntactically simpler cases with variations of the previous 'sed'
scripts.
The more syntactically complex multi-line cases would mostly really want
whitespace cleanup anyway.

This is the exact same thing as the 'alloc_obj()' version, only much
smaller because there are a lot fewer users of the *alloc_flex()
interface.
As with alloc_obj() version, this was done entirely with mindless brute
force, using the same script, except using 'flex' in the pattern rather
than 'objs*'.
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)
The resulting allocations no longer return "void *", instead returning
"TYPE *".

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.

performs maintenance work on the DAMON documentation (SeongJae Park)
- "mm: add and use vma_assert_stabilised() helper" refactors and cleans
up the core VMA code. The main aim here is to be able to use the mmap
write lock's lockdep state to perform various assertions regarding
the locking which the VMA code requires (Lorenzo Stoakes)
- "mm, swap: swap table phase II: unify swapin use" removes some old
swap code (swap cache bypassing and swap synchronization) which

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 x86 paravirt updates from Borislav Petkov:
- A nice cleanup to the paravirt code containing a unification of the
paravirt clock interface, taming the include hell by splitting the
pv_ops structure and removing of a bunch of obsolete code (Juergen
Gross)
* tag 'x86_paravirt_for_v7.0_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (23 commits)
x86/paravirt: Use XOR r32,r32 to clear register in pv_vcpu_is_preempted()
x86/paravirt: Remove trailing semicolons from alternative asm templates
x86/pvlocks: Move paravirt spinlock functions into own header
x86/paravirt: Specify pv_ops array in paravirt macros
x86/paravirt: Allow pv-calls outside paravirt.h
objtool: Allow multiple pv_ops arrays

...
- 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.

where addressed with the introduction of this flag
- Cleanup IRQF_ONESHOT and IRQF_NO_THREAD usage
Quite some drivers have inconsistent interrupt request flags related to
interrupt threading namely IRQF_ONESHOT and IRQF_NO_THREAD. This leads to
warnings and/or malfunction when forced interrupt threading is enabled.
- Remove stub primary (hard interrupt) handlers
A bunch of drivers implement a stub primary (hard interrupt) handler which

core code when the primary handler argument of request_thread_irq() is set
to NULL.

x86 PMU driver updates:
- Add support for the core PMU for Intel Diamond Rapids (DMR) CPUs.
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
(Dapeng Mi)
- Likewise, a large series adds uncore PMU support for
Intel Diamond Rapids (DMR) CPUs, which center 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.
(Zide Chen)
- Also add support for Add missing PMON units for Intel Panther Lake,
and support Nova Lake (NVL), which largely maps to Panther Lake.

"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.

- 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
targeting January 2027 removal"

Passing IRQF_ONESHOT ensures that the interrupt source is masked until
the secondary (threaded) handler is done. If only a primary handler is
used then the flag makes no sense because the interrupt can not fire
(again) while its handler is running.
Revert adding IRQF_ONESHOT to irqflags.

Restricted pointers ("%pK") were never meant to be used
through printk(). They can acquire sleeping locks in atomic contexts.
Switch to %px over the more secure %p as this usage is a debugging aid,
gated behind CONFIG_DEBUG_VIRTUAL and used by WARN().

The symbol PSR_ENDSTATE is pointless for userspace. Drop it from the
UAPI headers and instead inline it into the only two callers.
As as side-effect, remove a leak of an internal kconfig symbol through
the UAPI headers.

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
