Pull tracing tool updates from Steven Rostedt:
"Specific for timerlat:
- Improve the output of timerlat top by adding a missing \n, and by
avoiding printing color-formatting characters where they are
translated to regular characters.
- Improve timerlat auto-analysis output by replacing '\t' with spaces
to avoid copy-and-paste issues when reporting problems.
- Make the user-space (-u) option the default, as it is the most
complete test. Add a -k option to use the in-kernel workload.
- On timerlat top and hist, add a summary with the overall results.
For instance, the minimum value for all CPUs, the overall average
and the maximum value from all CPUs.
- timerlat hist was printing initial values (i.e., 0 as max, and ~0
as min) if the trace stopped before the first Ret-User event. This
problem was fixed by printing the " - " no value string to the
output if that was the case.
For all RTLA tools:
- Add a --warm-up <seconds> option, allowing the workload to run for
<seconds> before starting to collect results.
- Add a --trace-buffer-size option, allowing the user to set the
tracing buffer size for -t option. This option is mainly useful for
reducing the trace file. Now rtla depends on libtracefs >= 1.6.
- Fix the -t [trace_file] parsing, now it does not require the '='
before the option parameter, and better handles the multiple ways a
user can pass the trace_file.txt"

Pull tracing ring buffer updates from Steven Rostedt:
"Add ring_buffer memory mappings.
The tracing ring buffer was created based on being mostly used with
the splice system call. It is broken up into page ordered sub-buffers
and the reader swaps a new sub-buffer with an existing sub-buffer
that's part of the write buffer. It then has total access to the
swapped out sub-buffer and can do copyless movements of the memory
into other mediums (file system, network, etc).
The buffer is great for passing around the ring buffer contents in the
kernel, but is not so good for when the consumer is the user space
task itself.
A new interface is added that allows user space to memory map the ring
buffer. It will get all the write sub-buffers as well as reader
sub-buffer (that is not written to). It can send an ioctl to change
which sub-buffer is the new reader sub-buffer.
The ring buffer is read only to user space. It only needs to call the
ioctl when it is finished with a sub-buffer and needs a new sub-buffer
that the writer will not write over.
A self test program was also created for testing and can be used as an
example for the interface to user space. The libtracefs (external to
the kernel) also has code that interacts with this, although it is
disabled until the interface is in a official release. It can be
enabled by compiling the library with a special flag. This was used
for testing applications that perform better with the buffer being
mapped.
Memory mapped buffers have limitations. The main one is that it can
not be used with the snapshot logic. If the buffer is mapped,
snapshots will be disabled. If any logic is set to trigger snapshots
on a buffer, that buffer will not be allowed to be mapped"

Add the option allow the users to set a different buffer size for the
trace. For example, in large systems, the user might be interested on
reducing the trace buffer to avoid large tracing files.
The buffer size is specified in kB, and it is only affecting
the tracing instance.
The function trace_set_buffer_size() appears on libtracefs v1.6,
so increase the minimum required version on Makefile.config.

Pull cgroup updates from Tejun Heo:
- The locking around cpuset hotplug processing has always been a bit of
mess which was worked around by making hotplug processing
asynchronous. The asynchronity isn't great and led to other issues.
We tried to make the behavior synchronous a while ago but that led to
lockdep splats. Waiman took another stab at cleaning up and making it
synchronous. The patch has been in -next for well over a month and
there haven't been any complaints, so fingers crossed.

Pull KVM updates from Paolo Bonzini:
"ARM:
- Move a lot of state that was previously stored on a per vcpu basis
into a per-CPU area, because it is only pertinent to the host while
the vcpu is loaded. This results in better state tracking, and a
smaller vcpu structure.
- Add full handling of the ERET/ERETAA/ERETAB instructions in nested
virtualisation. The last two instructions also require emulating
part of the pointer authentication extension. As a result, the trap
handling of pointer authentication has been greatly simplified.
- Turn the global (and not very scalable) LPI translation cache into
a per-ITS, scalable cache, making non directly injected LPIs much
cheaper to make visible to the vcpu.
- A batch of pKVM patches, mostly fixes and cleanups, as the
upstreaming process seems to be resuming. Fingers crossed!
- Allocate PPIs and SGIs outside of the vcpu structure, allowing for
smaller EL2 mapping and some flexibility in implementing more or
less than 32 private IRQs.
- Purge stale mpidr_data if a vcpu is created after the MPIDR map has
been created.
- Preserve vcpu-specific ID registers across a vcpu reset.
- Various minor cleanups and improvements.
LoongArch:
- Add ParaVirt IPI support
- Add software breakpoint support
- Add mmio trace events support
RISC-V:
- Support guest breakpoints using ebreak
- Introduce per-VCPU mp_state_lock and reset_cntx_lock
- Virtualize SBI PMU snapshot and counter overflow interrupts
- New selftests for SBI PMU and Guest ebreak
- Some preparatory work for both TDX and SNP page fault handling.
This also cleans up the page fault path, so that the priorities of
various kinds of fauls (private page, no memory, write to read-only
slot, etc.) are easier to follow.
x86:
- Minimize amount of time that shadow PTEs remain in the special
REMOVED_SPTE state.
This is a state where the mmu_lock is held for reading but
concurrent accesses to the PTE have to spin; shortening its use
allows other vCPUs to repopulate the zapped region while the zapper
finishes tearing down the old, defunct page tables.
- Advertise the max mappable GPA in the "guest MAXPHYADDR" CPUID
field, which is defined by hardware but left for software use.
This lets KVM communicate its inability to map GPAs that set bits
51:48 on hosts without 5-level nested page tables. Guest firmware
is expected to use the information when mapping BARs; this avoids
that they end up at a legal, but unmappable, GPA.
- Fixed a bug where KVM would not reject accesses to MSR that aren't
supposed to exist given the vCPU model and/or KVM configuration.
- As usual, a bunch of code cleanups.
x86 (AMD):
- Implement a new and improved API to initialize SEV and SEV-ES VMs,
which will also be extendable to SEV-SNP.
The new API specifies the desired encryption in KVM_CREATE_VM and
then separately initializes the VM. The new API also allows
customizing the desired set of VMSA features; the features affect
the measurement of the VM's initial state, and therefore enabling
them cannot be done tout court by the hypervisor.
While at it, the new API includes two bugfixes that couldn't be
applied to the old one without a flag day in userspace or without
affecting the initial measurement. When a SEV-ES VM is created with
the new VM type, KVM_GET_REGS/KVM_SET_REGS and friends are rejected
once the VMSA has been encrypted. Also, the FPU and AVX state will
be synchronized and encrypted too.
- Support for GHCB version 2 as applicable to SEV-ES guests.
This, once more, is only accessible when using the new
KVM_SEV_INIT2 flow for initialization of SEV-ES VMs.
x86 (Intel):
- An initial bunch of prerequisite patches for Intel TDX were merged.
They generally don't do anything interesting. The only somewhat
user visible change is a new debugging mode that checks that KVM's
MMU never triggers a #VE virtualization exception in the guest.
- Clear vmcs.EXIT_QUALIFICATION when synthesizing an EPT Misconfig
VM-Exit to L1, as per the SDM.
Generic:
- Use vfree() instead of kvfree() for allocations that always use
vcalloc() or __vcalloc().
- Remove .change_pte() MMU notifier - the changes to non-KVM code are
small and Andrew Morton asked that I also take those through the
KVM tree.
The callback was only ever implemented by KVM (which was also the
original user of MMU notifiers) but it had been nonfunctional ever
since calls to set_pte_at_notify were wrapped with
invalidate_range_start and invalidate_range_end... in 2012.
Selftests:
- Enhance the demand paging test to allow for better reporting and
stressing of UFFD performance.
- Convert the steal time test to generate TAP-friendly output.
- Fix a flaky false positive in the xen_shinfo_test due to comparing
elapsed time across two different clock domains.
- Skip the MONITOR/MWAIT test if the host doesn't actually support
MWAIT.
- Avoid unnecessary use of "sudo" in the NX hugepage test wrapper
shell script, to play nice with running in a minimal userspace
environment.
- Allow skipping the RSEQ test's sanity check that the vCPU was able
to complete a reasonable number of KVM_RUNs, as the assert can fail
on a completely valid setup.
If the test is run on a large-ish system that is otherwise idle,
and the test isn't affined to a low-ish number of CPUs, the vCPU
task can be repeatedly migrated to CPUs that are in deep sleep
states, which results in the vCPU having very little net runtime
before the next migration due to high wakeup latencies.
- Define _GNU_SOURCE for all selftests to fix a warning that was
introduced by a change to kselftest_harness.h late in the 6.9
cycle, and because forcing every test to #define _GNU_SOURCE is
painful.
- Provide a global pseudo-RNG instance for all tests, so that library
code can generate random, but determinstic numbers.
- Use the global pRNG to randomly force emulation of select writes
from guest code on x86, e.g. to help validate KVM's emulation of
locked accesses.
- Allocate and initialize x86's GDT, IDT, TSS, segments, and default
exception handlers at VM creation, instead of forcing tests to
manually trigger the related setup.
Documentation:
- Fix a goof in the KVM_CREATE_GUEST_MEMFD documentation"

After ther -u addition, most of the known users are setting it. And
it makes sense, as it adds more information, and inherits the default
setup for the threads - e.g., cgroups configs.
Thus, if the user-space interface is available, enable -u. Otherwise,
use the in-kernel thread.
Add the -k option to allow the user to request kernel-threads.

On many cases, the results right after the startup are different
from the rest of the execution, biasing the results. For example,
on osnoise, the scheduler might take some time to adapt to the new
busy-loop workload.
Add the --warm-up <seconds> option, adding a warm-up phase (in
seconds) where the workload is set, but the results are discarded.

Pull networking updates from Jakub Kicinski:
"Core & protocols:
- Complete rework of garbage collection of AF_UNIX sockets.
AF_UNIX is prone to forming reference count cycles due to fd
passing functionality. New method based on Tarjan's Strongly
Connected Components algorithm should be both faster and remove a
lot of workarounds we accumulated over the years.
- Add TCP fraglist GRO support, allowing chaining multiple TCP
packets and forwarding them together. Useful for small switches /
routers which lack basic checksum offload in some scenarios (e.g.
PPPoE).
- Support using SMP threads for handling packet backlog i.e. packet
processing from software interfaces and old drivers which don't use
NAPI. This helps move the processing out of the softirq jumble.
- Continue work of converting from rtnl lock to RCU protection.
Don't require rtnl lock when reading: IPv6 routing FIB, IPv6
address labels, netdev threaded NAPI sysfs files, bonding driver's
sysfs files, MPLS devconf, IPv4 FIB rules, netns IDs, tcp metrics,
TC Qdiscs, neighbor entries, ARP entries via ioctl(SIOCGARP), a lot
of the link information available via rtnetlink.
- Small optimizations from Eric to UDP wake up handling, memory
accounting, RPS/RFS implementation, TCP packet sizing etc.
- Allow direct page recycling in the bulk API used by XDP, for +2%
PPS.
- Support peek with an offset on TCP sockets.
- Add MPTCP APIs for querying last time packets were received/sent/acked
and whether MPTCP "upgrade" succeeded on a TCP socket.
- Add intra-node communication shortcut to improve SMC performance.
- Add IPv6 (and IPv{4,6}-over-IPv{4,6}) support to the GTP protocol
driver.
- Add HSR-SAN (RedBOX) mode of operation to the HSR protocol driver.
- Add reset reasons for tracing what caused a TCP reset to be sent.
- Introduce direction attribute for xfrm (IPSec) states. State can be
used either for input or output packet processing.
Things we sprinkled into general kernel code:
- Add bitmap_{read,write}(), bitmap_size(), expose BYTES_TO_BITS().
This required touch-ups and renaming of a few existing users.
- Add Endian-dependent __counted_by_{le,be} annotations.
- Make building selftests "quieter" by printing summaries like
"CC object.o" rather than full commands with all the arguments.
Netfilter:
- Use GFP_KERNEL to clone elements, to deal better with OOM
situations and avoid failures in the .commit step.
BPF:
- Add eBPF JIT for ARCv2 CPUs.
- Support attaching kprobe BPF programs through kprobe_multi link in
a session mode, meaning, a BPF program is attached to both function
entry and return, the entry program can decide if the return
program gets executed and the entry program can share u64 cookie
value with return program. "Session mode" is a common use-case for
tetragon and bpftrace.
- Add the ability to specify and retrieve BPF cookie for raw
tracepoint programs in order to ease migration from classic to raw
tracepoints.
- Add an internal-only BPF per-CPU instruction for resolving per-CPU
memory addresses and implement support in x86, ARM64 and RISC-V
JITs. This allows inlining functions which need to access per-CPU
state.
- Optimize x86 BPF JIT's emit_mov_imm64, and add support for various
atomics in bpf_arena which can be JITed as a single x86
instruction. Support BPF arena on ARM64.
- Add a new bpf_wq API for deferring events and refactor
process-context bpf_timer code to keep common code where possible.
- Harden the BPF verifier's and/or/xor value tracking.
- Introduce crypto kfuncs to let BPF programs call kernel crypto
APIs.
- Support bpf_tail_call_static() helper for BPF programs with GCC 13.
- Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF
program to have code sections where preemption is disabled.
Driver API:
- Skip software TC processing completely if all installed rules are
marked as HW-only, instead of checking the HW-only flag rule by
rule.
- Add support for configuring PoE (Power over Ethernet), similar to
the already existing support for PoDL (Power over Data Line)
config.
- Initial bits of a queue control API, for now allowing a single
queue to be reset without disturbing packet flow to other queues.
- Common (ethtool) statistics for hardware timestamping.
Tests and tooling:
- Remove the need to create a config file to run the net forwarding
tests so that a naive "make run_tests" can exercise them.
- Define a method of writing tests which require an external endpoint
to communicate with (to send/receive data towards the test
machine). Add a few such tests.
- Create a shared code library for writing Python tests. Expose the
YAML Netlink library from tools/ to the tests for easy Netlink
access.
- Move netfilter tests under net/, extend them, separate performance
tests from correctness tests, and iron out issues found by running
them "on every commit".
- Refactor BPF selftests to use common network helpers.
- Further work filling in YAML definitions of Netlink messages for:
nftables, team driver, bonding interfaces, vlan interfaces, VF
info, TC u32 mark, TC police action.
- Teach Python YAML Netlink to decode attribute policies.
- Extend the definition of the "indexed array" construct in the specs
to cover arrays of scalars rather than just nests.
- Add hyperlinks between definitions in generated Netlink docs.
Drivers:
- Make sure unsupported flower control flags are rejected by drivers,
and make more drivers report errors directly to the application
rather than dmesg (large number of driver changes from Asbjørn
Sloth Tønnesen).

- Broadcom (bnxt):

Pull device mapper updates from Mike Snitzer:
- Add a dm-crypt optional "high_priority" flag that enables the crypt
workqueues to use WQ_HIGHPRI.
- Export dm-crypt workqueues via sysfs (by enabling WQ_SYSFS) to allow
for improved visibility and controls over IO and crypt workqueues.
- Fix dm-crypt to no longer constrain max_segment_size to PAGE_SIZE.
This limit isn't needed given that the block core provides late bio
splitting if bio exceeds underlying limits (e.g. max_segment_size).

Pull gpio updates from Bartosz Golaszewski
"This was a quiet release cycle for the GPIO tree and so this
pull-request is relatively small.
We have one new driver, some minor improvements to the GPIO core code
and across several drivers, some DT and documentation updates but in
general nothing stands out or is controversial. All changes have spent
time in next with no reported issues (or ones that were quickly
fixed).
GPIO core:
- remove more unused legacy interfaces (after converting the last
remaining users to better alternatives)
- update kerneldocs
- improve error handling and log messages in GPIO ACPI code
- remove dead code (always true checks) from GPIOLIB
New drivers:
- add a driver for Intel Granite Rapids-D vGPIO
Driver improvements:
- use -ENOTSUPP consistently in gpio-regmap and gpio-pcie-idio-24
- provide an ID table for gpio-cros-ec to avoid a driver name
fallback check
- add support for gpio-ranges for GPIO drivers supporting multiple
GPIO banks
- switch to using dynamic GPIO base in gpio-brcmstb
- fix irq handling in gpio-npcm-sgpio
- switch to memory mapped IO accessors in gpio-sch
DT bindings:

Pull pwm updates from Uwe Kleine-König:
"Apart for the normal updates for dt bindings, cleanups and support for
new device variants to existing drivers this completes the conversion
to pwmchip_alloc() which was started in the v6.9 development cycle.
Using pwmchip_alloc() is a precondition to the character device
support which allows easier and faster access to PWM devices. However
there are some issues I want to clean up before including it in
mainline, so this isn't contained here despite it was in next for some
time.

Stark, Jerome Brunet and Varshini Rajendran for their contributions.

Pull regulator updates from Mark Brown:
"There's one API update here, a new API factoring out a common pattern
for reference voltage supplies. These are supplies used as a reference
by analogue circuits where the consumer requests and enables the
supply, reads the voltage to calibrate the user and then never touches
it again. This is factored out into a single operation which just
returns the voltage and uses devm_ to manage the request and enable
portion.
Otherwise this has been a very quiet release, we've got some new
device support, some small fixes, housekeeping and cleanup work but
nothing substantial.
There's also some non-regulator changes in here, a number of users for
the new reference voltage API were merged along with it and some MFD
changes were pulled in as dependencies for new driver work.
Highlights:
- Add a new API for single operation handling of reference voltages
- Support for Allwinner AXP717 and D1, and NXP PCA9561A"

Pull thermal control updates from Rafael Wysocki:
"The most significant part of this is a rework of thermal governors,
including a redesign of the thermal governor interface and changes to
make some of them take trip point hysteresis into account properly, as
well as some related cleanups of the thermal governors and thermal
core.
The above is based on preliminary changes refactoring thermal data
structures and moving the definitions of some of them into the thermal
core which also ensure that trip point crossing notifications will be
sent to user space via netlink and recorded in the debug statistics in
temperature order.
In addition, netlink bind/unbind notifications are added to the
thermal core and the Intel HFI driver is modified to use them to avoid
sending netlink messages until there are subscribers.
Apart from that, multiple thermal drivers are updated which includes
new hardware support (MediaTek MT8188 and MT8186, Amlogic A1 thermal
sensor, Loongson-2K2000, Lmh QCM2290), fixes, cleanups and
documentation updates, and the recently added thermal debug code is
fixed and cleaned up.
Specifics:
- Redesign the thermal governor interface to allow the governors to
work in a more straightforward way (Rafael Wysocki)
- Make thermal governors take the current trip point thresholds into
account in their computations which allows trip hysteresis to be
observed more accurately (Rafael Wysocki)
- Make the thermal core manage passive polling for thermal zones and
remove passive polling management from thermal governors (Rafael
Wysocki)
- Refactor trip point representation and move the definition of
thermal governor and thermal zone device structures to the thermal
core (Rafael Wysocki)
- Sort trip point crossing notifications and debug recording of trip
point crossing events by temperature (Rafael Wysocki)
- Improve the handling of cooling device states and thermal
mitigation episodes in progress in the thermal debug code (Rafael
Wysocki)
- Avoid excessive updates of trip point statistics and clean up the
printing of thermal mitigation episode information (Rafael Wysocki)
- Clean up thermal governors and thermal core (Rafael Wysocki)
- Allow thermal drivers to register notifiers that will be invoked on
netlink events like BIND and UNBIND, so that they can adjust their
activity depending on whether or not there are any subscribers of
netlink messages coming from them, and make the Intel HFI driver
use this mechanism (Stanislaw Gruszka)
- Adjust the update delay and capabilities-per-event values in the
Intel HFI thermal driver to prevent it from missing events and
allow it to process more data in one go (Ricardo Neri)
- Add missing MODULE_DESCRIPTION() to multiple files in the
int340x_thermal and intel_soc_dts_iosf drivers (Srinivas
Pandruvada)
- Replace deprecated strncpy() with strscpy() in the int340x_thermal
driver (Justin Stitt)
- Add QCM2290 compatible DT bindings for Lmh and fix a NULL pointer
dereference in the lmh driver when the SCM is not present (Konrad
Dybcio)
- Use the strreplace() function instead of doing it manually in the
Armada driver (Rasmus Villemoes)
- Convert st,stih407-thermal to DT schema and fix up missing
properties (Raphael Gallais-Pou)
- Add suspend/resume by restoring the context of the tsens sensor
(Priyansh Jain)
- Support A1 SoC family Thermal Sensor controller and add the DT
bindings (Dmitry Rokosov)
- Improve the temperature approximation calculation and consolidate
the Tj constant into a shared area of the structure instead of
duplicating it on the Rcar Gen3 (Niklas Söderlund)
- Fix the Mediatek LVTS sensor coefficient for the MT8192 in order to
support it correctly (Hsin-Te Yuan)
- Fix a NULL pointer dereference in the tsens driver when the
function compute_intercept_slope() is called with a NULL parameter
(Aleksandr Mishin)
- Remove some unused fields in struct qpnp_tm_chip and k3_bandgap
(Christophe Jaillet)
- Fix up calibration efuse data decoding, consolidate the code by
checking boundaries and refactor some part of the LVTS Mediatek
driver. After setting the scene, add MT8186 and MT8188 along with
the DT bindings (Nicolas Pitre)
- Add Loongson-2K2000 support after some minor code adjustements and
providing the DT bindings definition (Binbin Zhou)"

Pull x86 interrupt handling updates from Thomas Gleixner:
"Add support for posted interrupts on bare metal.
Posted interrupts is a virtualization feature which allows to inject
interrupts directly into a guest without host interaction. The VT-d
interrupt remapping hardware sets the bit which corresponds to the
interrupt vector in a vector bitmap which is either used to inject the
interrupt directly into the guest via a virtualized APIC or in case
that the guest is scheduled out provides a host side notification
interrupt which informs the host that an interrupt has been marked
pending in the bitmap.
This can be utilized on bare metal for scenarios where multiple
devices, e.g. NVME storage, raise interrupts with a high frequency. In
the default mode these interrupts are handles independently and
therefore require a full roundtrip of interrupt entry/exit.
Utilizing posted interrupts this roundtrip overhead can be avoided by
coalescing these interrupt entries to a single entry for the posted
interrupt notification. The notification interrupt then demultiplexes
the pending bits in a memory based bitmap and invokes the
corresponding device specific handlers.
Depending on the usage scenario and device utilization throughput
improvements between 10% and 130% have been measured.
As this is only relevant for high end servers with multiple device
queues per CPU attached and counterproductive for situations where
interrupts are arriving at distinct times, the functionality is opt-in
via a kernel command line parameter"

Pull interrupt subsystem updates from Thomas Gleixner:
"Core code:
- Interrupt storm detection for the lockup watchdog:
Lockups which are caused by interrupt storms are not easy to debug
because there is no information about the events which make the
lockup detector trigger.
To make this more user friendly, provide an extenstion to interrupt
statistics which allows to take snapshots and an interface to
retrieve the delta to the snapshot. Use this new mechanism in the
watchdog code to do a two stage lockup analysis by taking the
snapshot and printing the deltas for the topmost active interrupts
on the second trigger.
Note: This contains both the interrupt and the watchdog changes as
the latter depend on the former obviously.
- Avoid summation loops in the /proc/interrupts output and use the
global counter when possible
- Skip suspended interrupts on CPU hotplug operations to ensure that
they are not delivered before the system resumes the device drivers
when coming out of suspend.
- On CPU hot-unplug interrupts which are affine to the outgoing CPU
are migrated to a different CPU in the affinity mask. This can fail
when the CPUs have no vectors left. Instead of giving up try to
migrate it to any online CPU and thereby breaking the affinity
setting in order to prevent a stale device interrupt which targets
an offline CPU
- The usual small cleanups
Driver code:
- Support for the RISCV AIA MSI controller
- Make the interrupt allocation for the Loongson PCH controller more
flexible to prevent vector exhaustion
- The usual set of cleanups and fixes all over the place"

Pull timers and timekeeping updates from Thomas Gleixner:
"Core code:
- Make timekeeping and VDSO time readouts resilent against math
overflow:
In guest context the kernel is prone to math overflow when the host
defers the timer interrupt due to overload, malfunction or malice.
This can be mitigated by checking the clocksource delta for the
maximum deferrement which is readily available. If that value is
exceeded then the code uses a slowpath function which can handle
the multiplication overflow.
This functionality is enabled unconditionally in the kernel, but
made conditional in the VDSO code. The latter is conditional
because it allows architectures to optimize the check so it is not
causing performance regressions.
On X86 this is achieved by reworking the existing check for
negative TSC deltas as a negative delta obviously exceeds the
maximum deferrement when it is evaluated as an unsigned value. That
avoids two conditionals in the hotpath and allows to hide both the
negative delta and the large delta handling in the same slow path.

- The usual boring cleanups and enhancements

The MediaTek MT7921S is a WiFi/Bluetooth combo chip that works over
SDIO. WiFi and Bluetooth are separate SDIO functions within the chip.
While the Bluetooth SDIO function is fully discoverable, the chip has
a pin that can reset just the Bluetooth core, as opposed to the full
chip. This should be described in the device tree.
Add a device tree binding for the Bluetooth SDIO function of the MT7921S
specifically to document the reset line. This binding is based on the MMC
controller binding, which specifies one device node per SDIO function.

Extend the binding with its DT compatible using fallback

We've added 119 non-merge commits during the last 14 day(s) which contain
a total of 134 files changed, 9462 insertions(+), 4742 deletions(-).
The main changes are:
1) Add BPF JIT support for 32-bit ARCv2 processors, from Shahab Vahedi.
2) Add BPF range computation improvements to the verifier in particular
around XOR and OR operators, refactoring of checks for range computation
and relaxing MUL range computation so that src_reg can also be an unknown
scalar, from Cupertino Miranda.
3) Add support to attach kprobe BPF programs through kprobe_multi link in
a session mode, meaning, a BPF program is attached to both function entry
and return, the entry program can decide if the return program gets
executed and the entry program can share u64 cookie value with return
program. Session mode is a common use-case for tetragon and bpftrace,
from Jiri Olsa.
4) Fix a potential overflow in libbpf's ring__consume_n() and improve libbpf
as well as BPF selftest's struct_ops handling, from Andrii Nakryiko.
5) Improvements to BPF selftests in context of BPF gcc backend,
from Jose E. Marchesi & David Faust.
6) Migrate remaining BPF selftest tests from test_sock_addr.c to prog_test-
-style in order to retire the old test, run it in BPF CI and additionally
expand test coverage, from Jordan Rife.
7) Big batch for BPF selftest refactoring in order to remove duplicate code

Pull Rust updates from Miguel Ojeda:
"The most notable change is the drop of the 'alloc' in-tree fork. This
is nicely reflected in the diffstat as a ~10k lines drop. In turn,
this makes the version upgrades way simpler and smaller in the future,
e.g. the latest one in commit 56f64b370612 ("rust: upgrade to Rust
1.78.0").
More importantly, this increases the chances that a newer compiler
version just works, which in turn means supporting several compiler
versions is easier now. Thus we will look into finally setting a
minimum version in the near future.
Toolchain and infrastructure:
- Upgrade to Rust 1.78.0
This time around, due to how the kernel and Rust schedules have
aligned, there are two upgrades in fact. These allow us to remove
one more unstable feature ('offset_of') from the list, among other
improvements
- Drop 'alloc' in-tree fork of the standard library crate, which
means all the unstable features used by 'alloc' (~30 language ones,
~60 library ones) are not a concern anymore
- Support DWARFv5 via the '-Zdwarf-version' flag
- Support zlib and zstd debuginfo compression via the
'-Zdebuginfo-compression' flag
'kernel' crate:
- Support allocation flags ('GFP_*'), particularly in 'Box' (via
'BoxExt'), 'Vec' (via 'VecExt'), 'Arc' and 'UniqueArc', as well as
in the 'init' module APIs
- Remove usage of the 'allocator_api' unstable feature
- Remove 'try_' prefix in allocation APIs' names
- Add 'VecExt' (an extension trait) to be able to drop the 'alloc'
fork
- Add the '{make,to}_{upper,lower}case()' methods to 'CStr'/'CString'
- Add the 'as_ptr' method to 'ThisModule'
- Add the 'from_raw' method to 'ArcBorrow'
- Add the 'into_unique_or_drop' method to 'Arc'
- Display column number in the 'dbg!' macro output by applying the
equivalent change done to the standard library one
- Migrate 'Work' to '#[pin_data]' thanks to the changes in the
'macros' crate, which allows to remove an unsafe call in its 'new'
associated function
- Prevent namespacing issues when using the '[try_][pin_]init!'
macros by changing the generated name of guard variables
- Make the 'get' method in 'Opaque' const
- Implement the 'Default' trait for 'LockClassKey'
- Remove unneeded 'kernel::prelude' imports from doctests
- Remove redundant imports
'macros' crate:
- Add 'decl_generics' to 'parse_generics()' to support default
values, and use that to allow them in '#[pin_data]'
Helpers:
- Trivial English grammar fix
Documentation:
- Add section on Rust Kselftests to the 'Testing' document
- Expand the 'Abstractions vs. bindings' section of the 'General
Information' document"

git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf-next
Pablo Neira Ayuso says:
====================
Netfilter updates for net-next
The following patchset contains Netfilter updates for net-next:
Patch #1 skips transaction if object type provides no .update interface.
Patch #2 skips NETDEV_CHANGENAME which is unused.
Patch #3 enables conntrack to handle Multicast Router Advertisements and
Multicast Router Solicitations from the Multicast Router Discovery
protocol (RFC4286) as untracked opposed to invalid packets.
From Linus Luessing.
Patch #4 updates DCCP conntracker to mark invalid as invalid, instead of
dropping them, from Jason Xing.
Patch #5 uses NF_DROP instead of -NF_DROP since NF_DROP is 0,
also from Jason.
Patch #6 removes reference in netfilter's sysctl documentation on pickup
entries which were already removed by Florian Westphal.
Patch #7 removes check for IPS_OFFLOAD flag to disable early drop which
allows to evict entries from the conntrack table,
also from Florian.
Patches #8 to #16 updates nf_tables pipapo set backend to allocate
the datastructure copy on-demand from preparation phase,
to better deal with OOM situations where .commit step is too late
to fail. Series from Florian Westphal.
Patch #17 adds a selftest with packetdrill to cover conntrack TCP state
transitions, also from Florian.
Patch #18 use GFP_KERNEL to clone elements from control plane to avoid
quick atomic reserves exhaustion with large sets, reporter refers
to million entries magnitude.
