Pull zstd updates from Nick Terrell:
"Update the kernel to upstream zstd v1.5.2 [0]. Specifically to the tag
v1.5.2-kernel [1] which includes several cherrypicked fixes for the
kernel on top of v1.5.2.
Excepting the MAINTAINERS change, all the changes in this can be
generated by:
git clone https://github.com/facebook/zstd
cd zstd/contrib/linux-kernel
git checkout v1.5.2-kernel
LINUX=/path/to/linux/repo make import
Additionally, this includes several minor typo fixes, which have all
been fixed upstream so they are maintained on the next import"

Github deprecated the git:// links about a year ago, so let's move to
the https:// URLs instead.

at_hdmac.c
Do not expose register definitions, structures and helpers via a .h file
because there are used only by at_hdmac.c. Since there are no other users,
remove the ambiguity and move all the .h contents to the .c file.
One may notice some checkpatch warnings and errors with this move. The move
was done "as it was", checkpatch complaints can be fixed in a further
patch.

Commit cd0ab43ec91a ("dmaengine: remove iop-adma driver") removes the
driver's source code, but misses to remove the MAINTAINERS section.
Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a
broken file pattern.
Remove the INTEL IOP-ADMA DMA DRIVER section pointing to the removed
driver.

Move Sergey to co-maintainer for zram/zsmalloc since he has helped to
contribute/review those areas actively for eight years, which is quite
helpful. Since Nitin has been inactive for several years, it's time to
move his name into CREDITS.

Pull perf tools updates from Arnaldo Carvalho de Melo:
"Libraries:
- Drop the old copy of libtraceevent in tools/lib/traceevent/ now
that all major distros ship it from its external repository.
This is now just another feature detection, emitting a warning when
the libtraceevent-dev[el] package isn't installed, disabling the
build of perf features and tools that strictly require parsing
things from tracefs while keeping the core functionality present
and working with a subset of the events, the most used ones like
CPU cycles, hardware cache and also vendor events, etc.
This was tested with lots of containers for Fedora, Debian,
OpenSUSE, Alpine Linux, Ubuntu, with cross builds, etc.
Build:
- Update to C standard to gnu11, like was done for the kernel.
- Install the tools/lib/ libraries locally instead of having headers
searched directly from the source code directories, to help the
cases where we can build either from in-kernel source libraries or
from the same library shipped as a distro package, as is the case
with libbpf and was the case with libtraceevent.
perf stat:
- Do not delay the workload with --delay, the delay is just for
starting to count the events, to skip noise at workload startup.
- When we have events for each cgroup, the metric should be printed
for each cgroup separately.
$ perf stat -a --for-each-cgroup system.slice,user.slice --metric-only sleep 1
Performance counter stats for 'system wide':
GHz insn per cycle branch-misses of all branches
system.slice 3.792 0.61 3.24%
user.slice 3.661 2.32 0.37%
- Fix printing field separator in CSV metrics output.
- Fix --metric-only --json output.
- Fix summary output in CSV with --metric-only.
- Update event group check for support of uncore event.
perf test:
- Stop requiring a C toolchain in shell tests, instead add a workload
option that has all the previously C snippets built as part of
'perf test -w' that then get used in the 'perf test' shell scripts.
- Add event group test for events in multiple PMUs
- The "kernel lock contention analysis" test should not print
warnings in quiet mode.
- Add attr tests for ARM64's new VG register.
- Fix record test on KVM guests, as using precise flag with the
br_inst_retired.near_call event causes the test fail on KVM guests,
even when the guests have PMU forwarding enabled and the event
itself is supported, so just remove the precise flag from the
event.
- Add mechanism for skipping attr tests on specific kernel versions
where it is known that these checks will fail.
- Skip watchpoint tests if no watchpoints available.
- Add more Intel PT 'perf test' entries: hybrid CPUs, split the
packet decoder into a suite of subtests.
perf script:
- Introduce task analyzer python script, where one first records some events:
Recording can be done in two ways:
$ perf script record tasks-analyzer -- sleep 10
$ perf record -e sched:sched_switch -a -- sleep 10
The script can parse any perf.data files, as long as it has
sched:sched_switch events, other events will be ignored.
The most simple report use case is to just call the script without
arguments.
Runtime is the time the task was running on the CPU, Time Out-In is
the time between the process being scheduled *out* and scheduled
back *in*. So the last time span between two executions:
$ perf script report tasks-analyzer
Switched-In Switched-Out CPU PID TID Comm Runtime Time Out-In

perf lock:
- Allow concurrent record and report to support live monitoring of
kernel lock contention without BPF:

- Implement -t/--threads option when using BPF:

- Add -l/--lock-addr to aggregate per-lock-instance contention:

1 436 ns 436 ns 436 ns ffff9260bfda4f60
perf record:
- Add remaining branch filters: "no_cycles", "no_flags" & "hw_index",
to be used with hardware such as Intel's LBR that allows things
like stitching stacks of two samples to overcome the limits of the
number of LBR registers.
Symbol resolution:
- Handle .debug files created with 'objcopy --only-keep-debug', where
program headers are zeroed and thus can't be used for adjustments,
use the info in the runtime_ss (runtime ELF) instead.
perf trace:
- Add BPF based augmenter for the 'perf_event_open's 'struct
perf_event_attr' argument.
- Add BPF based augmenter for the 'clock_gettime's 'struct timespec'
argument.
- In both cases the syscall tracepoint has just the pointer value, we
need to hook a BPF program to collect the pointer contents, and
then, in userspace, pretty print it in 'perf trace'.
perf list:
- Introduce JSON output of events.
- Streamline how the expression specifying what events should be
shown is handled, fixing several corner cases, such as the metric
filter that is specified as a glob but was using strstr().
perf probe:
- Fix to avoid crashing if DW_AT_decl_file is NULL, coping with clang
generating DWARF5 like that.
- Use dwarf_attr_integrate() as generic DWARF attr accessor as it
supersedes dwarf_attr(), supporting abstact origin DIEs.
perf inject:
- Set PERF_RECORD_MISC_BUILD_ID_SIZE in the PERF_RECORD_HEADER_BUILD_ID
so that perf.data readers can get the real build-id size and avoid
trailing zeroes.
perf data:
- Add tracepoint fields when converting a perf.data file to JSON.
arm64:
- Fix mksyscalltbl, don't lose syscalls due to sort -nu.
- Add Arm Neoverse V2 PMU events.
riscv:
- Add riscv sbi firmware std event files.
- Add Sifive U74 vendor events (JSON) file.
- Add some more events and metrics for Alderlake/Alderlake-N.
Documentation:
- Add data documentation for the PMU structs in the C source code.
Miscellaneous:
- Periodic sanitization of headers, adding missing includes, removing
needless ones, creating new ones, etc.
- Use sig_atomic_t for signal handlers to avoid undefined behaviour
in all perf tools.
- Fixes for libbpf 1.0+ compatibility (maps, etc) on 'perf trace' BPF
examples.
- Remove some old perf bpf examples, leave the best ones that
demonstrate how to associate BPF functions to points in the kernel.
- Make quiet mode consistent between tools.
- Use dedicated non-atomic clear/set bit helpers.
- Use "grep -E" instead of "egrep" as recommended by warning emitted
by GNU grep since at least version 3.8.
- Complete list of supported subcommands in the 'perf daemon' help
message.
- Update John Garry's email address for arm64 perf tooling on the
MAINTAINERS file, he moved from Huawei to Oracle"

Pull char/misc driver updates from Greg KH:
"Here is the large set of char/misc and other driver subsystem changes
for 6.2-rc1. Nothing earth-shattering in here at all, just a lot of
new driver development and minor fixes.
Highlights include:
- fastrpc driver updates
- iio new drivers and updates
- habanalabs driver updates for new hardware and features
- slimbus driver updates
- speakup module parameters added to aid in boot time configuration
- i2c probe_new conversions for lots of different drivers
- other small driver fixes and additions
One semi-interesting change in here is the increase of the number of
misc dynamic minors available to 1048448 to handle new huge-cpu
systems.
All of these have been in linux-next for a while with no reported
problems"

1st set of IIO new device support, feature and cleanup for 6.2 (take2)
We have finally managed to take the mlock mutex entirely private so as
to avoid it being used for multiple purposes. Now it is just used to
protect device mode transitions (typically to and from buffered capture).
Includes merge of an immutable i2c branch to get the new
i2c_client_get_device_id() (thanks to Wolfram for providing the branch).
Based on rc3 to pick up some precursor fixes from early in the cycle and
avoid an unnecessarily messy history.
New device support
* adi,ad4310
- New driver to support this very flexible measurement device including
a 24 bit ADC. Later fix for documentation build issue.
* adi,adxl355
- Add support of the ADXL359 accelerometer.
* adi,ltc2983
- Support additional variants of the temperatures sensor:
LTC2984 with an EEPROM
LTC2985, LTC2986 with only 10 channels.
* invensense,icm42600
- Add support for icm42631 (needed only ID and WHOAMI)
* kionix,kx022a
- New driver for this 3 axis accelerometer.
* maxim,max11401
- New driver to support this 24-bit 10 channel ADC.
Includes some new ABI to support configuration of notch filters.
* mediatek,mt6370
- Add new driver to support the ADC part of the mt6370.
* st,lsm6dsx
- Add support for LSM6DSV accelerometer and gyroscope. Simple additional
of chip specific data and IDs.
- Add support for LSM6DSV16X accelerometer and gyroscope. Compatible with
features currently implemented for the LSM6DSV.
* st,stm32-adc
- Add support for stm32pm13x SoCs.
core / subsystem wide:
- Add new IIO_STATIC_CONST_DEVICE_ATTR() which is a dance necessary to
allow for the wrapping of attributes in the code that duplicates them
for multiple buffers.
- Harden against future issues with expectation that all buffer attributes
are iio_dev_attrs by changing the code to take an array of pointers
of the correct type.
- Last transitions of drivers to local locks rather than missuses of mlock.
- Add an iio_device_claim_buffer_mode() callback to avoid a race in the
max30100 driver without directly using mlock.
- Move mlock to the opaque IIO device structure to prevent misuse.
- Add missing spi_device_id tables to support auto loading of modules.
- Update some ADI maintainers in DT bindings.
- A few more moves of bus drivers and core module sets to export
name spaces.
- Extensive use of new devm_regulator_get_enable() and friends.
- Switch a bunch of i2c drivers to probe_new() including the bmp280
which makes use of the new i2c_client_get_device_id() helper to
simplify this change.
dt-bindings:
- More use of spi-peripheral-props.yaml.
Features
* freescale,mpl115
- Use runtime PM to implement shutdown GPIO support.
* melexis,mlx90632
- More sophisticated runtime power management
- Provide access to sampling frequency.
- Trivial follow up fixes.
* microchip,mcp3911
- Support control of PGA.
* st,lsm6dsx
- Add support for software triggers for cases where the IRQ lines
are not wired up.
* vishay,vcnl4000
- Add control of integration time.
Minor cleanups and fixes
* adi,ad4130
- Improve ABI documentation formatting.
- Kconfig dependency fixup.
* adi,ad5758
- Minor dt binding fix.
* adi,ad9834
- Tidy up line breaks.
* adi,ade7854
- Minor improvement in code clarity by replacing a ternary.
* adi,admv8818
- Harden code against hardware returning wrong values.
* adi,adxl355
- Warn only if unknown device ID detected to allow for fall back
device tree compatibles on future devices.
* adi,ltc2983
- dt-bindings clarifications and general improvements.
- Ensure DMA safe buffer for bulk writes without relying on current
regmap implementation choices.
* avago,adps9960
- Fix up a disconnect between event enable attributes and what was
enabled.
* bosch,bma400
- Switch to dev_err_probe() from open coded EPROBE_DEFER handling.
* cosmic,cc10001
- Fully devm managed probe() and related tidying up.
* meas,ms5611
- Add an example of spi-max-frequency.
* meleixs,mlx90632
- Tidy up confusing error return value.
- Style improvements.
* multiplexer
- Switch to dev_err_probe() from open coded EPROBE_DEFER handling.
* qcom,spmi-vadc
- Minor dt binding improvements.
* rockchip,saradc
- Add ID for rv1126.
* semtech,sx9360
- Add SAMM0208 ACPI ID. Doesn't appear to be a valid vendor prefix
but is in the wild.
* st,lsm6dsx
- Factor out common code as _device_set_enable().
- Fix up wrong docs after LSM6DSV addition.
* st,stm32-adc
- Manage the min sampling time on all internal channels.
* trig,sysfs
- Improve error labels.

- Use mhi_soc_reset() API for resetting the modem in case of crash.
- Fixed a race condition between mhi_prepare_channel() and M0 state
transition. This can happen when mhi_prepare_channel() was updating the
read/write pointers and in parallel, the mhi_pm_m0_transition() rings
the doorbell of all channels without checking if it was enabled or not.
Fixed the race by ringing the doorbell only for the enabled channels in
mhi_pm_m0_transition().

- Added a secondary "AT" port using the OEM reserved channel of Telit FN990

- Added support for a SDX55 variant modem that exists in the Qualcomm
SC8280XP Compute Reference Design (CRD).
- Added support for a T99W175 variant modem manufactured by HP. The modem
uses the same configuration as of T99W175, but with a different VID:PID.

Pull USB and Thunderbolt driver updates from Greg KH:
"Here is the large set of USB and Thunderbolt driver changes for
6.2-rc1. Overall, thanks to the removal of a driver, more lines were
removed than added, a nice change. Highlights include:
- removal of the sisusbvga driver that was not used by anyone anymore
- minor thunderbolt driver changes and tweaks
- chipidea driver updates
- usual set of typec driver features and hardware support added
- musb minor driver fixes
- fotg210 driver fixes, bringing that hardware back from the "dead"
- minor dwc3 driver updates
- addition, and then removal, of a list.h helper function for many
USB and other subsystem drivers, that ended up breaking the build.
That will come back for 6.3-rc1, it missed this merge window.
- usual xhci updates and enhancements
- usb-serial driver updates and support for new devices
- other minor USB driver updates
All of these have been in linux-next for a while with no reported
problems"

The Faraday FOTG210 is a dual-mode OTG USB controller that can
act as host, peripheral or both. To be able to probe from one
hardware description and to follow the pattern of other dual-
mode controllers such as MUSB or MTU3 we need to collect the
two, currently completely separate drivers in the same
directory.
After this, users need to select the main symbol USB_FOTG210
and then each respective subdriver. We pave the road to
compile both drivers into the same kernel and select the
one we want to use at probe() time, and possibly add OTG
support in the end.
This patch doesn't do much more than create the new symbol
and collect the drivers in one place. We also add a comment
for the section of dual-mode controllers in the Kconfig
file so people can see what these selections are about.
Also add myself as maintainer as there has been little
response on my patches to these drivers.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing updates from Steven Rostedt:
- Add options to the osnoise tracer:
- 'panic_on_stop' option that panics the kernel if osnoise is
greater than some user defined threshold.
- 'preempt' option, to test noise while preemption is disabled
- 'irq' option, to test noise when interrupts are disabled
- Add .percent and .graph suffix to histograms to give different
outputs
- Add nohitcount to disable showing hitcount in histogram output
- Add new __cpumask() to trace event fields to annotate that a unsigned
long array is a cpumask to user space and should be treated as one.
- Add trace_trigger kernel command line parameter to enable trace event
triggers at boot up. Useful to trace stack traces, disable tracing
and take snapshots.
- Fix x86/kmmio mmio tracer to work with the updates to lockdep
- Unify the panic and die notifiers
- Add back ftrace_expect reference that is used to extract more
information in the ftrace_bug() code.
- Have trigger filter parsing errors show up in the tracing error log.
- Updated MAINTAINERS file to add kernel tracing mailing list and
patchwork info
- Use IDA to keep track of event type numbers.
- And minor fixes and clean ups

Pull kvm updates from Paolo Bonzini:
"ARM64:
- Enable the per-vcpu dirty-ring tracking mechanism, together with an
option to keep the good old dirty log around for pages that are
dirtied by something other than a vcpu.
- Switch to the relaxed parallel fault handling, using RCU to delay
page table reclaim and giving better performance under load.
- Relax the MTE ABI, allowing a VMM to use the MAP_SHARED mapping
option, which multi-process VMMs such as crosvm rely on (see merge
commit 382b5b87a97d: "Fix a number of issues with MTE, such as
races on the tags being initialised vs the PG_mte_tagged flag as
well as the lack of support for VM_SHARED when KVM is involved.
Patches from Catalin Marinas and Peter Collingbourne").
- Merge the pKVM shadow vcpu state tracking that allows the
hypervisor to have its own view of a vcpu, keeping that state
private.
- Add support for the PMUv3p5 architecture revision, bringing support
for 64bit counters on systems that support it, and fix the
no-quite-compliant CHAIN-ed counter support for the machines that
actually exist out there.
- Fix a handful of minor issues around 52bit VA/PA support (64kB
pages only) as a prefix of the oncoming support for 4kB and 16kB
pages.
- Pick a small set of documentation and spelling fixes, because no
good merge window would be complete without those.
s390:
- Second batch of the lazy destroy patches
- First batch of KVM changes for kernel virtual != physical address
support
- Removal of a unused function
x86:
- Allow compiling out SMM support
- Cleanup and documentation of SMM state save area format
- Preserve interrupt shadow in SMM state save area
- Respond to generic signals during slow page faults
- Fixes and optimizations for the non-executable huge page errata
fix.
- Reprogram all performance counters on PMU filter change
- Cleanups to Hyper-V emulation and tests
- Process Hyper-V TLB flushes from a nested guest (i.e. from a L2
guest running on top of a L1 Hyper-V hypervisor)
- Advertise several new Intel features
- x86 Xen-for-KVM:
- Allow the Xen runstate information to cross a page boundary
- Allow XEN_RUNSTATE_UPDATE flag behaviour to be configured
- Add support for 32-bit guests in SCHEDOP_poll
- Notable x86 fixes and cleanups:
- One-off fixes for various emulation flows (SGX, VMXON, NRIPS=0).
- Reinstate IBPB on emulated VM-Exit that was incorrectly dropped
a few years back when eliminating unnecessary barriers when
switching between vmcs01 and vmcs02.
- Clean up vmread_error_trampoline() to make it more obvious that
params must be passed on the stack, even for x86-64.
- Let userspace set all supported bits in MSR_IA32_FEAT_CTL
irrespective of the current guest CPUID.
- Fudge around a race with TSC refinement that results in KVM
incorrectly thinking a guest needs TSC scaling when running on a
CPU with a constant TSC, but no hardware-enumerated TSC
frequency.
- Advertise (on AMD) that the SMM_CTL MSR is not supported
- Remove unnecessary exports
Generic:
- Support for responding to signals during page faults; introduces
new FOLL_INTERRUPTIBLE flag that was reviewed by mm folks
Selftests:
- Fix an inverted check in the access tracking perf test, and restore
support for asserting that there aren't too many idle pages when
running on bare metal.
- Fix build errors that occur in certain setups (unsure exactly what
is unique about the problematic setup) due to glibc overriding
static_assert() to a variant that requires a custom message.
- Introduce actual atomics for clear/set_bit() in selftests
- Add support for pinning vCPUs in dirty_log_perf_test.
- Rename the so called "perf_util" framework to "memstress".
- Add a lightweight psuedo RNG for guest use, and use it to randomize
the access pattern and write vs. read percentage in the memstress
tests.
- Add a common ucall implementation; code dedup and pre-work for
running SEV (and beyond) guests in selftests.
- Provide a common constructor and arch hook, which will eventually
be used by x86 to automatically select the right hypercall (AMD vs.
Intel).
- A bunch of added/enabled/fixed selftests for ARM64, covering
memslots, breakpoints, stage-2 faults and access tracking.
- x86-specific selftest changes:
- Clean up x86's page table management.
- Clean up and enhance the "smaller maxphyaddr" test, and add a
related test to cover generic emulation failure.
- Clean up the nEPT support checks.
- Add X86_PROPERTY_* framework to retrieve multi-bit CPUID values.
- Fix an ordering issue in the AMX test introduced by recent
conversions to use kvm_cpu_has(), and harden the code to guard
against similar bugs in the future. Anything that tiggers
caching of KVM's supported CPUID, kvm_cpu_has() in this case,
effectively hides opt-in XSAVE features if the caching occurs
before the test opts in via prctl().
Documentation:
- Remove deleted ioctls from documentation
- Clean up the docs for the x86 MSR filter.
- Various fixes"

Pull gpio updates from Bartosz Golaszewski:
"We have a new GPIO multiplexer driver, bunch of driver updates and
refactoring in the core GPIO library.
GPIO core:
- teach gpiolib to work with software nodes for HW description
- remove ARCH_NR_GPIOS treewide as we no longer impose any limit on
the number of GPIOS since the allocation became entirely dynamic
- add support for HW quirks for Cirrus CS42L56 codec, Marvell NFC
controller, Freescale PCIe and Ethernet controller, Himax LCDs and
Mediatek mt2701
- refactor OF quirk code
- some general refactoring of the OF and ACPI code, adding new
helpers, minor tweaks and fixes, making fwnode usage consistent
etc.
GPIO uAPI:
- fix an issue where the user-space can trigger a NULL-pointer
dereference in the kernel by opening a device file, forcing a
driver unbind and then calling one of the syscalls on the
associated file descriptor
New drivers:
- add gpio-latch: a new GPIO multiplexer based on latches connected
to other GPIOs
Driver updates:
- convert i2c GPIO expanders to using .probe_new()
- drop the gpio-sta2x11 driver
- factor out common code for the ACCES IDIO-16 family of controllers
and use this new library wherever applicable in drivers
- add DT support to gpio-hisi
- allow building gpio-davinci as a module and increase its maxItems
property
- add support for a new model to gpio-pca9570
- other minor changes to various drivers"

devices within the ACCES IDIO-16 family such as the 104-IDIO-16 and
the PCI-IDIO-16.
A CONFIG_GPIO_IDIO_16 Kconfig option is introduced by this patch.
Modules wanting access to these idio-16 library functions should select
this Kconfig option and import the GPIO_IDIO_16 symbol namespace.

git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim:
"In this round, we've added two features: F2FS_IOC_START_ATOMIC_REPLACE
and a per-block age-based extent cache.
F2FS_IOC_START_ATOMIC_REPLACE is a variant of the previous atomic
write feature which guarantees a per-file atomicity. It would be more
efficient than AtomicFile implementation in Android framework.
The per-block age-based extent cache implements another type of extent
cache in memory which keeps the per-block age in a file, so that block
allocator could split the hot and cold data blocks more accurately.
Enhancements:
- introduce F2FS_IOC_START_ATOMIC_REPLACE
- refactor extent_cache to add a new per-block-age-based extent cache support
- introduce discard_urgent_util, gc_mode, max_ordered_discard sysfs knobs
- add proc entry to show discard_plist info
- optimize iteration over sparse directories
- add barrier mount option
Bug fixes:
- avoid victim selection from previous victim section
- fix to enable compress for newly created file if extension matches
- set zstd compress level correctly
- initialize locks early in f2fs_fill_super() to fix bugs reported by syzbot
- correct i_size change for atomic writes
- allow to read node block after shutdown
- allow to set compression for inlined file
- fix gc mode when gc_urgent_high_remaining is 1
- should put a page when checking the summary info
Minor fixes and various clean-ups in GC, discard, debugfs, sysfs, and
doc"

Pull kernel hardening updates from Kees Cook:
- Convert flexible array members, fix -Wstringop-overflow warnings, and
fix KCFI function type mismatches that went ignored by maintainers
(Gustavo A. R. Silva, Nathan Chancellor, Kees Cook)
- Remove the remaining side-effect users of ksize() by converting
dma-buf, btrfs, and coredump to using kmalloc_size_roundup(), add
more __alloc_size attributes, and introduce full testing of all
allocator functions. Finally remove the ksize() side-effect so that
each allocation-aware checker can finally behave without exceptions
- Introduce oops_limit (default 10,000) and warn_limit (default off) to
provide greater granularity of control for panic_on_oops and
panic_on_warn (Jann Horn, Kees Cook)
- Introduce overflows_type() and castable_to_type() helpers for cleaner
overflow checking
- Improve code generation for strscpy() and update str*() kern-doc
- Convert strscpy and sigphash tests to KUnit, and expand memcpy tests
- Always use a non-NULL argument for prepare_kernel_cred()
- Disable structleak plugin in FORTIFY KUnit test (Anders Roxell)
- Adjust orphan linker section checking to respect CONFIG_WERROR (Xin
Li)
- Make sure siginfo is cleared for forced SIGKILL (haifeng.xu)
