Pull s390 updates from Vasily Gorbik:
- Remove restrictions on PAI NNPA and crypto counters, enabling
concurrent per-task and system-wide sampling and counting events
- Switch to GENERIC_CPU_DEVICES by setting up the CPU present mask in
the architecture code and letting the generic code handle CPU
bring-up
- Add support for the diag204 busy indication facility to prevent
undesirable blocking during hypervisor logical CPU utilization
queries. Implement results caching
- Improve the handling of Store Data SCLP events by suppressing
unnecessary warning, preventing buffer release in I/O during
failures, and adding timeout handling for Store Data requests to
address potential firmware issues
- Provide optimized __arch_hweight*() implementations
- Remove the unnecessary CPU KOBJ_CHANGE uevents generated during
topology updates, as they are unused and also not present on other
architectures
- Cleanup atomic_ops, optimize __atomic_set() for small values and
__atomic_cmpxchg_bool() for compilers supporting flag output
constraint
- Couple of cleanups for KVM:
- Move and improve KVM struct definitions for DAT tables from
gaccess.c to a new header
- Pass the asce as parameter to sie64a()
- Make the crdte() and cspg() page table handling wrappers return a
boolean to indicate success, like the other existing "compare and
swap" wrappers
- Add documentation for HWCAP flags
- Switch to obtaining total RAM pages from memblock instead of
totalram_pages() during mm init, to ensure correct calculation of
zero page size, when defer_init is enabled
- Refactor lowcore access and switch to using the get_lowcore()
function instead of the S390_lowcore macro
- Cleanups for PG_arch_1 and folio handling in UV and hugetlb code
- Add missing MODULE_DESCRIPTION() macros
- Fix VM_FAULT_HWPOISON handling in do_exception()

Pull ftrace updates from Steven Rostedt:
"Rewrite of function graph tracer to allow multiple users
Up until now, the function graph tracer could only have a single user
attached to it. If another user tried to attach to the function graph
tracer while one was already attached, it would fail. Allowing
function graph tracer to have more than one user has been asked for
since 2009, but it required a rewrite to the logic to pull it off so
it never happened. Until now!
There's three systems that trace the return of a function. That is
kretprobes, function graph tracer, and BPF. kretprobes and function
graph tracing both do it similarly. The difference is that kretprobes
uses a shadow stack per callback and function graph tracer creates a
shadow stack for all tasks. The function graph tracer method makes it
possible to trace the return of all functions. As kretprobes now needs
that feature too, allowing it to use function graph tracer was needed.
BPF also wants to trace the return of many probes and its method
doesn't scale either. Having it use function graph tracer would
improve that.
By allowing function graph tracer to have multiple users allows both
kretprobes and BPF to use function graph tracer in these cases. This
will allow kretprobes code to be removed in the future as it's version
will no longer be needed.
Note, function graph tracer is only limited to 16 simultaneous users,
due to shadow stack size and allocated slots"

Pull probes updates from Masami Hiramatsu:
"Uprobes:
- x86/shstk: Make return uprobe work with shadow stack
- Add uretprobe syscall which speeds up the uretprobe 10-30% faster.
This syscall is automatically used from user-space trampolines
which are generated by the uretprobe. If this syscall is used by
normal user program, it will cause SIGILL. Note that this is
currently only implemented on x86_64.
(This also has two fixes for adjusting the syscall number to avoid
conflict with new *attrat syscalls.)
- uprobes/perf: fix user stack traces in the presence of pending
uretprobe. This corrects the uretprobe's trampoline address in the
stacktrace with correct return address
- selftests/x86: Add a return uprobe with shadow stack test
- selftests/bpf: Add uretprobe syscall related tests.
- test case for register integrity check
- test case with register changing case
- test case for uretprobe syscall without uprobes (expected to fail)
- test case for uretprobe with shadow stack
- selftests/bpf: add test validating uprobe/uretprobe stack traces
- MAINTAINERS: Add uprobes entry. This does not specify the tree but
to clarify who maintains and reviews the uprobes
Kprobes:
- tracing/kprobes: Test case cleanups.
Replace redundant WARN_ON_ONCE() + pr_warn() with WARN_ONCE() and
remove unnecessary code from selftest
- tracing/kprobes: Add symbol counting check when module loads.
This checks the uniqueness of the probed symbol on modules. The
same check has already done for kernel symbols
(This also has a fix for build error with CONFIG_MODULES=n)
Cleanup:
- Add MODULE_DESCRIPTION() macros for fprobe and kprobe examples"

There is no support for HWPOISON, MEMORY_FAILURE, or ARCH_HAS_COPY_MC on
s390. Therefore we do not expect to see VM_FAULT_HWPOISON in
do_exception().
However, since commit af19487f00f3 ("mm: make PTE_MARKER_SWAPIN_ERROR more
general"), it is possible to see VM_FAULT_HWPOISON in combination with
PTE_MARKER_POISONED, even on architectures that do not support HWPOISON
otherwise. In this case, we will end up on the BUG() in do_exception().
Fix this by treating VM_FAULT_HWPOISON the same as VM_FAULT_SIGBUS, similar
to x86 when MEMORY_FAILURE is not configured. Also print unexpected fault
flags, for easier debugging.
Note that VM_FAULT_HWPOISON_LARGE is not expected, because s390 cannot
support swap entries on other levels than PTE level.

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Jakub Kicinski:
"Not much excitement - a handful of large patchsets (devmem among them)
did not make it in time.
Core & protocols:
- Use local_lock in addition to local_bh_disable() to protect per-CPU
resources in networking, a step closer for local_bh_disable() not
to act as a big lock on PREEMPT_RT
- Use flex array for netdevice priv area, ensure its cache alignment
- Add a sysctl knob to allow user to specify a default rto_min at
socket init time. Bit of a big hammer but multiple companies were
independently carrying such patch downstream so clearly it's useful
- Support scheduling transmission of packets based on CLOCK_TAI
- Un-pin TCP TIMEWAIT timer to avoid it firing on CPUs later cordoned
off using cpusets
- Support multiple L2TPv3 UDP tunnels using the same 5-tuple address
- Allow configuration of multipath hash seed, to both allow
synchronizing hashing of two routers, and preventing partial
accidental sync
- Improve TCP compliance with RFC 9293 for simultaneous connect()
- Support sending NAT keepalives in IPsec ESP in UDP states.
Userspace IKE daemon had to do this before, but the kernel can
better keep track of it
- Support sending supervision HSR frames with MAC addresses stored in
ProxyNodeTable when RedBox (i.e. HSR-SAN) is enabled
- Introduce IPPROTO_SMC for selecting SMC when socket is created
- Allow UDP GSO transmit from devices with no checksum offload
- openvswitch: add packet sampling via psample, separating the
sampled traffic from "upcall" packets sent to user space for
forwarding
- nf_tables: shrink memory consumption for transaction objects
Things we sprinkled into general kernel code:
- Power Sequencing subsystem (used by Qualcomm Bluetooth driver for
QCA6390) [ Already merged separately - Linus ]
- Add IRQ information in sysfs for auxiliary bus
- Introduce guard definition for local_lock
- Add aligned flavor of __cacheline_group_{begin, end}() markings for
grouping fields in structures
BPF:
- Notify user space (via epoll) when a struct_ops object is getting
detached/unregistered
- Add new kfuncs for a generic, open-coded bits iterator
- Enable BPF programs to declare arrays of kptr, bpf_rb_root, and
bpf_list_head
- Support resilient split BTF which cuts down on duplication and
makes BTF as compact as possible WRT BTF from modules
- Add support for dumping kfunc prototypes from BTF which enables
both detecting as well as dumping compilable prototypes for kfuncs
- riscv64 BPF JIT improvements in particular to add 12-argument
support for BPF trampolines and to utilize bpf_prog_pack for the
latter
- Add the capability to offload the netfilter flowtable in XDP layer
through kfuncs
Driver API:
- Allow users to configure IRQ tresholds between which automatic IRQ
moderation can choose
- Expand Power Sourcing (PoE) status with power, class and failure
reason. Support setting power limits
- Track additional RSS contexts in the core, make sure configuration
changes don't break them
- Support IPsec crypto offload for IPv6 ESP and IPv4 UDP-encapsulated

UML should not be using the architecture native runtime constants, since
that requires also having the appropriate instruction fixups (and all
the linker script details).
Not that using that code would be impossible, but it's not worth it.
Just point UML at the generic version.

Pull EFI updates from Ard Biesheuvel:
"Note the removal of the EFI fake memory map support - this is believed
to be unused and no longer worth supporting. However, we could easily
bring it back if needed.
With recent developments regarding confidential VMs and unaccepted
memory, combined with kexec, creating a known inaccurate view of the
firmware's memory map and handing it to the OS is a feature we can
live without, hence the removal. Alternatively, I could imagine making
this feature mutually exclusive with those confidential VM related
features, but let's try simply removing it first.
Summary:
- Drop support for the 'fake' EFI memory map on x86
- Add an SMBIOS based tweak to the EFI stub instructing the firmware
on x86 Macbook Pros to keep both GPUs enabled
- Replace 0-sized array with flexible array in EFI memory attributes
table handling
- Drop redundant BSS clearing when booting via the native PE
entrypoint on x86
- Avoid returning EFI_SUCCESS when aborting on an out-of-memory
condition
- Cosmetic tweak for arm64 KASLR loading logic"

Pull SoC dt updates from Arnd Bergmann:
"The devicetree updates are fairly well spread out across platforms,
with Qualcomm making up about a third of the total.
There are three new SoCs in existing product families this:
- NXP i.MX95 is a variant of i.MX93, now with six Cortex-A55 cores
instead of just two as well as a GPU and more high-speed I/O
devices.
- Qualcomm QCS8550 is a variant of SM8550 for IOT devices
- Airoha EN7581 is a 10G-PON network chip and related to the MT7981
Wireless router chip from its parent Mediatek.
In total there are 58 new machines, including four riscv boards and
eight for 32-bit arm.
The most exciting new addition is probably a pair of laptops based on
the Qualcomm x1e80100 (Snapdragon X1 Elite) chip, the Asus Vivobook
S15 and the Lenovo Yoga Slim7x.
Other noteworthy new additions are:
- A total of 20 Qualcomm based machines, mostly Android devices from
Samsung, Motorola and LG, as well as a wireless router and some
reference designs
- Six NXP i.MX based machines, mostly industrial boards along with
some reference designs
- Mediatek sees some interesting Filogic based routers including the
"OpenWRT One", a few new Chromebooks as well as single-board
computers.
- Four machines from Solidrun based on Marvell cn913x, replacing the
older Armada 8000 based counterparts
- The four Amlogic machines are all set top boxes or reference
designs for them
- The nine new Rockchips machines are mostly single-board computers
including some interesting ones based on the rk3588 chip like the
ROCK 5 ITX board and the CM3588 with its four NVMe slots
- The RISC-V boards are all single-board computers based on Starfive
JH7110, Microchip MPFS and Allwinner D1, which all had similar
boards already

Pull x86 SEV updates from Borislav Petkov:
- Add support for running the kernel in a SEV-SNP guest, over a Secure
VM Service Module (SVSM).
When running over a SVSM, different services can run at different
protection levels, apart from the guest OS but still within the
secure SNP environment. They can provide services to the guest, like
a vTPM, for example.
This series adds the required facilities to interface with such a
SVSM module.
- The usual fixlets, refactoring and cleanups
[ And as always: "SEV" is AMD's "Secure Encrypted Virtualization".
I can't be the only one who gets all the newer x86 TLA's confused,
can I?

irqchip. We also have some GICv3 optimisation for pseudo-NMIs that has
been queued via the arm64 tree. Otherwise the usual perf updates,
kselftest, various small cleanups.
Core:
- Virtual CPU hotplug support for arm64 ACPI systems
- cpufeature infrastructure cleanups and making the FEAT_ECBHB ID
bits visible to guests
- CPU errata: expand the speculative SSBS workaround to more CPUs
- GICv3, use compile-time PMR values: optimise the way regular IRQs
are masked/unmasked when GICv3 pseudo-NMIs are used, removing the
need for a static key in fast paths by using a priority value
chosen dynamically at boot time
ACPI:
- 'acpi=nospcr' option to disable SPCR as default console for arm64
- Move some ACPI code (cpuidle, FFH) to drivers/acpi/arm64/
Perf updates:
- Rework of the IMX PMU driver to enable support for I.MX95
- Enable support for tertiary match groups in the CMN PMU driver
- Initial refactoring of the CPU PMU code to prepare for the fixed
instruction counter introduced by Arm v9.4

Merge arm64 support for proper 'unsafe' user accessor functionality,
with 'asm goto' for handling exceptions.
The arm64 user access code used the slow fallback code for the user
access code, which generates horrendous code for things like
strncpy_from_user(), because it causes us to generate code for SW PAN
and for range checking for every individual word.
Teach arm64 about 'user_access_begin()' and the so-called 'unsafe' user
access functions that take an error label and use 'asm goto' to make all
the exception handling be entirely out of line.
[ These user access functions are called 'unsafe' not because the
concept is unsafe, but because the low-level accessor functions
absolutely have to be protected by the 'user_access_begin()' code,
because that's what does the range checking.
So the accessor functions have that scary name to make sure people
don't think they are usable on their own, and cannot be mis-used the
way our old "double underscore" versions of __get_user() and friends
were ]
The "(early part)" of the branch is because the full branch also
improved on the "access_ok()" function, but the exact semantics of TBI
(top byte ignore) have to be discussed before doing that part. So this
just does the low-level accessor update to use "asm goto".
* 'arm64-uaccess' (early part):
arm64: start using 'asm goto' for put_user()
arm64: start using 'asm goto' for get_user() when available

Merge minor word-at-a-time instruction choice improvements for x86 and
arm64.
This is the second of four branches that came out of me looking at the
code generation for path lookup on arm64.
The word-at-a-time infrastructure is used to do string operations in
chunks of one word both when copying the pathname from user space (in
strncpy_from_user()), and when parsing and hashing the individual path
components (in link_path_walk()).
In particular, the "find the first zero byte" uses various bit tricks to
figure out the end of the string or path component, and get the length
without having to do things one byte at a time. Both x86-64 and arm64
had less than optimal code choices for that.
The commit message for the arm64 change in particular tries to explain
the exact code flow for the zero byte finding for people who care. It's
made a bit more complicated by the fact that we support big-endian
hardware too, and so we have some extra abstraction layers to allow
different models for finding the zero byte, quite apart from the issue
of picking specialized instructions.
* word-at-a-time:
arm64: word-at-a-time: improve byte count calculations for LE
x86-64: word-at-a-time: improve byte count calculations

Merge runtime constants infrastructure with implementations for x86 and
arm64.
This is one of four branches that came out of me looking at profiles of
my kernel build filesystem load on my 128-core Altra arm64 system, where
pathname walking and the user copies (particularly strncpy_from_user()
for fetching the pathname from user space) is very hot.
This is a very specialized "instruction alternatives" model where the
dentry hash pointer and hash count will be constants for the lifetime of
the kernel, but the allocation are not static but done early during the
kernel boot. In order to avoid the pointer load and dynamic shift, we
just rewrite the constants in the instructions in place.
We can't use the "generic" alternative instructions infrastructure,
because different architectures do it very differently, and it's
actually simpler to just have very specific helpers, with a fallback to
the generic ("old") model of just using variables for architectures that
do not implement the runtime constant patching infrastructure.

* runtime-constants:
arm64: add 'runtime constant' support
runtime constants: add x86 architecture support
runtime constants: add default dummy infrastructure
vfs: dcache: move hashlen_hash() from callers into d_hash()

Commit 917195d6f829 ("ARM: pxa: consolidate GPIO chip platform data")
tried to reuse the same instance of platform data for PXA25x and PXA27x
GPIO controllers by moving it into arch/arm/mach-pxa/devices.c
Unfortunately this file is built for other PXA variants which resulted
in the following error:
>> arm-linux-gnueabi-ld: arch/arm/mach-pxa/devices.o:(.data+0x167c): undefined reference to `gpio_set_wake'
Fix this by using #ifdef around PXA25x and PXA27x GPIO controller device
structures and associated data.

After discussing with Arnd [1] it's preferable to change uretprobe
syscall number to 467 to omit the merge conflict with xattrat syscalls.
Also changing the ABI to 'common' which will ease up the global
scripts/syscall.tbl management. One consequence is we generate uretprobe
syscall numbers for ABIs that do not support uretprobe syscall, but the
syscall still returns -ENOSYS when called in that ABI.

Pull clocksource/event driver updates from Daniel Lezcano:
- Remove unnecessary local variables initialization as they will be
initialized in the code path anyway right after on the ARM arch
timer and the ARM global timer (Li kunyu)
- Fix a race condition in the interrupt leading to a deadlock on the
SH CMT driver. Note that this fix was not tested on the platform
using this timer but the fix seems reasonable enough to be picked
confidently (Niklas Söderlund)
- Increase the rating of the gic-timer and use the configured width
clocksource register on the MIPS architecture (Jiaxun Yang)
- Add the DT bindings for the TMU on the Renesas platforms (Geert
Uytterhoeven)
- Add the DT bindings for the SOPHGO SG2002 clint on RiscV (Thomas
Bonnefille)
- Add the rtl-otto timer driver along with the DT bindings for the
Realtek platform (Chris Packham)
