This reverts commit 6946c72. Jean Delvare points out that the patch does not completely fix the reported problem, that it in fact introduces a (new) race condition, and that it may actually not be needed in the first place. Various AI reviews agree. Specific and relevant AI feedback: " This reordering sets the driver data to NULL before removing the sensor attributes in the loop below. ibmpex_show_sensor() retrieves this driver data via dev_get_drvdata() but does not check if it is NULL before dereferencing it to access data->sensors[]. If a userspace process reads a sensor file (like temp1_input) while this delete function is running, could it race with the dev_set_drvdata(..., NULL) call here and crash in ibmpex_show_sensor()? Would it be safer to keep the original order where device_remove_file() is called before clearing the driver data? device_remove_file() should wait for any active sysfs callbacks to complete, which might already prevent the use-after-free this patch intends to fix. " Revert the offending patch. If it can be shown that the originally reported alleged race condition does indeed exist, it can always be re-introduced with a complete fix.

When MPQ8785 reports VOUT_MODE as VID mode, mpq8785_identify() configures the driver for direct mode. The subsequent pmbus_identify_common() check then fails due to a mismatch between the reported mode and the configured mode, causing device initialization to fail. Override the reported VOUT_MODE to direct mode to keep the driver configuration consistent with the reported mode and allow successful device initialization. This does not change how voltages are interpreted, but avoids a false identification failure caused by mismatched mode handling.

The LWMI_SUPP_MAY_{GET,SET} macros are fundamentally broken. When I
introduced them, I meant to check LWMI_SUPP_VALID *and* the
corresponding bits for get/set capabilities. However, `supported &
LWMI_SUPP_MAY_{GET,SET}' means *or*, so it accidentally passes the check
when LWMI_SUPP_VALID is set.
Fix them by only including the corresponding get/set bit without
LWMI_SUPP_VALID. Meanwhile, rename them to LWMI_SUPP_{GET,SET} to make
them less confusing.

The layer masks data structure tracks the requested but unfulfilled access rights during an operation's security check. It stores one bit for each combination of access right and layer index. If the bit is set, that access right is not granted (yet) in the given layer and we have to traverse the path further upwards to grant it. Previously, the layer masks were stored as arrays mapping from access right indices to layer_mask_t. The layer_mask_t value then indicates all layers in which the given access right is still (tentatively) denied. This patch introduces struct layer_access_masks instead: This struct contains an array with the access_mask_t of each (tentatively) denied access right in that layer. The hypothesis of this patch is that this simplifies the code enough so that the resulting code will run faster: * We can use bitwise operations in multiple places where we previously looped over bits individually with macros. (Should require less branch speculation and lends itself to better loop unrolling.) * Code is ~75 lines smaller. Other noteworthy changes: * In no_more_access(), call a new helper function may_refer(), which only solves the asymmetric case. Previously, the code interleaved the checks for the two symmetric cases in RENAME_EXCHANGE. It feels that the code is clearer when renames without RENAME_EXCHANGE are more obviously the normal case. Tradeoffs: This change improves performance, at a slight size increase to the layer masks data structure. This fixes the size of the data structure at 32 bytes for all types of access rights. (64, once we introduce a 17th filesystem access right). For filesystem access rights, at the moment, the data structure has the same size as before, but once we introduce the 17th filesystem access right, it will double in size (from 32 to 64 bytes), as access_mask_t grows from 16 to 32 bit [1].

Pull crypto library updates from Eric Biggers:
- Add support for verifying ML-DSA signatures.
ML-DSA (Module-Lattice-Based Digital Signature Algorithm) is a
recently-standardized post-quantum (quantum-resistant) signature
algorithm. It was known as Dilithium pre-standardization.
The first use case in the kernel will be module signing. But there
are also other users of RSA and ECDSA signatures in the kernel that
might want to upgrade to ML-DSA eventually.
- Improve the AES library:
- Make the AES key expansion and single block encryption and
decryption functions use the architecture-optimized AES code.
Enable these optimizations by default.
- Support preparing an AES key for encryption-only, using about
half as much memory as a bidirectional key.
- Replace the existing two generic implementations of AES with a
single one.
- Simplify how Adiantum message hashing is implemented. Remove the
"nhpoly1305" crypto_shash in favor of direct lib/crypto/ support for
NH hashing, and enable optimizations by default.

Pull module updates from Sami Tolvanen:
"Module signing:
- Remove SHA-1 support for signing modules.
SHA-1 is no longer considered secure for signatures due to
vulnerabilities that can lead to hash collisions. None of the major
distributions use SHA-1 anymore, and the kernel has defaulted to
SHA-512 since v6.11.
Note that loading SHA-1 signed modules is still supported.
- Update scripts/sign-file to use only the OpenSSL CMS API for
signing.
As SHA-1 support is gone, we can drop the legacy PKCS#7 API which
was limited to SHA-1. This also cleans up support for legacy
OpenSSL versions.
Cleanups and fixes:
- Use system_dfl_wq instead of the per-cpu system_wq following the
ongoing workqueue API refactoring.
- Avoid open-coded kvrealloc() in module decompression logic by using
the standard helper.
- Improve section annotations by replacing the custom __modinit with
__init_or_module and removing several unused __INIT*_OR_MODULE
macros.
- Fix kernel-doc warnings in include/linux/moduleparam.h.
- Ensure set_module_sig_enforced is only declared when module signing

'#[export]', '#[vtable]', '#[kunit_tests]') to use the 'syn'
parsing library which we introduced last cycle, with better
diagnostics
This also allows to support '#[cfg]' properly in the '#[vtable]'
macro, to support arbitrary types in 'module!' macro (not just an
identifier) and to remove several custom parsing helpers we had
- Use 'quote!' from the recently vendored 'quote' library and remove
our custom one
The vendored one also allows us to avoid quoting '"' and '{}'
inside the template anymore and editors can now highlight it. In
addition, it improves robustness as it eliminates the need for
string quoting and escaping
- Use 'pin_init::zeroed()' to simplify KUnit code
'pin-init' crate:
- Rewrite all procedural macros ('[pin_]init!', '#[pin_data]',
'#[pinned_drop]', 'derive([Maybe]Zeroable)') to use the 'syn'
parsing library which we introduced last cycle, with better
diagnostics
- Implement 'InPlaceWrite' for '&'static mut MaybeUninit<T>'. This
enables users to use external allocation mechanisms such as
'static_cell'
- Support tuple structs in 'derive([Maybe]Zeroable)'
- Support attributes on fields in '[pin_]init!' (such as
'#[cfg(...)]')
- Add a '#[default_error(<type>)]' attribute to '[pin_]init!' to
override the default error (when no '? Error' is specified)
- Support packed structs in '[pin_]init!' with
'#[disable_initialized_field_access]'
- Remove 'try_[pin_]init!' in favor of merging their feature with
'[pin_]init!'. Update the kernel's own 'try_[pin_]init!' macros to
use the 'default_error' attribute
- Correct 'T: Sized' bounds to 'T: ?Sized' in the generated
'PinnedDrop' check by '#[pin_data]'
Documentation:
- Conclude the Rust experiment
MAINTAINERS:
- Add "RUST [RUST-ANALYZER]" entry for the rust-analyzer support.
Tamir and Jesung will take care of it. They have both been active
around it for a while. The new tree will flow through the Rust one

"x86 PMU driver updates:
- Add support for the core PMU for Intel Diamond Rapids (DMR) CPUs
(Dapeng Mi)
Compared to previous iterations of the Intel PMU code, there's been
a lot of changes, which center around three main areas:
- Introduce the OFF-MODULE RESPONSE (OMR) facility to replace the
Off-Core Response (OCR) facility
- New PEBS data source encoding layout
- Support the new "RDPMC user disable" feature
- Likewise, a large series adds uncore PMU support for Intel Diamond
Rapids (DMR) CPUs (Zide Chen)
This centers around these four main areas:
- DMR may have two Integrated I/O and Memory Hub (IMH) dies,
separate from the compute tile (CBB) dies. Each CBB and each IMH
die has its own discovery domain.
- Unlike prior CPUs that retrieve the global discovery table
portal exclusively via PCI or MSR, DMR uses PCI for IMH PMON
discovery and MSR for CBB PMON discovery.
- DMR introduces several new PMON types: SCA, HAMVF, D2D_ULA, UBR,
PCIE4, CRS, CPC, ITC, OTC, CMS, and PCIE6.
- IIO free-running counters in DMR are MMIO-based, unlike SPR.
- Also add support for Add missing PMON units for Intel Panther Lake,
and support Nova Lake (NVL), which largely maps to Panther Lake.
(Zide Chen)
- KVM integration: Add support for mediated vPMUs (by Kan Liang and
Sean Christopherson, with fixes and cleanups by Peter Zijlstra,
Sandipan Das and Mingwei Zhang)
- Add Intel cstate driver to support for Wildcat Lake (WCL) CPUs,
which are a low-power variant of Panther Lake (Zide Chen)
- Add core, cstate and MSR PMU support for the Airmont NP Intel CPU
(aka MaxLinear Lightning Mountain), which maps to the existing
Airmont code (Martin Schiller)

Pull locking updates from Ingo Molnar:
"Lock debugging:
- Implement compiler-driven static analysis locking context checking,
using the upcoming Clang 22 compiler's context analysis features
(Marco Elver)
We removed Sparse context analysis support, because prior to
removal even a defconfig kernel produced 1,700+ context tracking
Sparse warnings, the overwhelming majority of which are false
positives. On an allmodconfig kernel the number of false positive
context tracking Sparse warnings grows to over 5,200... On the plus
side of the balance actual locking bugs found by Sparse context
analysis is also rather ... sparse: I found only 3 such commits in
the last 3 years. So the rate of false positives and the
maintenance overhead is rather high and there appears to be no
active policy in place to achieve a zero-warnings baseline to move
the annotations & fixers to developers who introduce new code.
Clang context analysis is more complete and more aggressive in
trying to find bugs, at least in principle. Plus it has a different
model to enabling it: it's enabled subsystem by subsystem, which
results in zero warnings on all relevant kernel builds (as far as
our testing managed to cover it). Which allowed us to enable it by
default, similar to other compiler warnings, with the expectation
that there are no warnings going forward. This enforces a
zero-warnings baseline on clang-22+ builds (Which are still limited
in distribution, admittedly)
Hopefully the Clang approach can lead to a more maintainable
zero-warnings status quo and policy, with more and more subsystems
and drivers enabling the feature. Context tracking can be enabled
for all kernel code via WARN_CONTEXT_ANALYSIS_ALL=y (default
disabled), but this will generate a lot of false positives.
( Having said that, Sparse support could still be added back,
if anyone is interested - the removal patch is still
relatively straightforward to revert at this stage. )

Pull scheduler updates from Ingo Molnar:
"Scheduler Kconfig space updates:
- Further consolidate configurable preemption modes (Peter Zijlstra)
Reduce the number of architectures that are allowed to offer
PREEMPT_NONE and PREEMPT_VOLUNTARY, reducing the number of
preemption models from four to just two: 'full' and 'lazy' on
up-to-date architectures (arm64, loongarch, powerpc, riscv, s390,
x86).
None and voluntary are only available as legacy features on
platforms that don't implement lazy preemption yet, or which don't
even support preemption.
The goal is to eventually remove cond_resched() and voluntary
preemption altogether.
RSEQ based 'scheduler time slice extension' support (Thomas Gleixner
and Peter Zijlstra):
This allows a thread to request a time slice extension when it enters
a critical section to avoid contention on a resource when the thread
is scheduled out inside of the critical section.
- Add fields and constants for time slice extension
- Provide static branch for time slice extensions
- Add statistics for time slice extensions
- Add prctl() to enable time slice extensions
- Implement sys_rseq_slice_yield()
- Implement syscall entry work for time slice extensions
- Implement time slice extension enforcement timer
- Reset slice extension when scheduled
- Implement rseq_grant_slice_extension()
- entry: Hook up rseq time slice extension

improves the scalability of various workloads (Shubhang Kaushik)
- Reorder fields in 'struct rq' for better caching (Blake Jones)
- Fair scheduler SMP NOHZ balancing code speedups (Shrikanth Hegde):
- Move checking for nohz cpus after time check
- Change likelyhood of nohz.nr_cpus
- Remove nohz.nr_cpus and use weight of cpumask instead
- Avoid false sharing for sched_clock_irqtime (Wangyang Guo)
- Cleanups (Yury Norov):
- Drop useless cpumask_empty() in find_energy_efficient_cpu()
- Simplify task_numa_find_cpu()
- Use cpumask_weight_and() in sched_balance_find_dst_group()
DL scheduler updates:
- Add a deadline server for sched_ext tasks (by Andrea Righi and Joel
Fernandes, with fixes by Peter Zijlstra)
RT scheduler updates:
- Skip currently executing CPU in rto_next_cpu() (Chen Jinghuang)
Entry code updates and performance improvements (Jinjie Ruan)
This is part of the scheduler tree in this cycle due to inter-
dependencies with the RSEQ based time slice extension work:
- Remove unused syscall argument from syscall_trace_enter()
- Rework syscall_exit_to_user_mode_work() for architecture reuse
- Add arch_ptrace_report_syscall_entry/exit()
- Inline syscall_exit_work() and syscall_trace_enter()
Scheduler core updates (Peter Zijlstra):
- Rework sched_class::wakeup_preempt() and rq_modified_*()
- Avoid rq->lock bouncing in sched_balance_newidle()
- Rename rcu_dereference_check_sched_domain() =>
rcu_dereference_sched_domain()
- <linux/compiler_types.h>: Add the __signed_scalar_typeof() helper
Fair scheduler updates/refactoring (Peter Zijlstra and Ingo Molnar):
- Fold the sched_avg update
- Change rcu_dereference_check_sched_domain() to rcu-sched
- Switch to rcu_dereference_all()
- Remove superfluous rcu_read_lock()
- Limit hrtick work
- Join two #ifdef CONFIG_FAIR_GROUP_SCHED blocks
- Clean up comments in 'struct cfs_rq'
- Separate se->vlag from se->vprot
- Rename cfs_rq::avg_load to cfs_rq::sum_weight
- Rename cfs_rq::avg_vruntime to ::sum_w_vruntime & helper functions
- Introduce and use the vruntime_cmp() and vruntime_op() wrappers for
wrapped-signed aritmetics
- Sort out 'blocked_load*' namespace noise

- Export hidden tracepoints to modules (Gabriele Monaco)
- Convert copy_from_user() + kstrtouint() to kstrtouint_from_user()
(Fushuai Wang)

Pull f2fs updates from Jaegeuk Kim:
"In this development cycle, we focused on several key performance
optimizations:
- introducing large folio support to enhance read speeds for
immutable files
- reducing checkpoint=enable latency by flushing only committed dirty
pages
- implementing tracepoints to diagnose and resolve lock priority
inversion.
Additionally, we introduced the packed_ssa feature to optimize the SSA
footprint when utilizing large block sizes.
Detail summary:
Enhancements:
- support large folio for immutable non-compressed case
- support non-4KB block size without packed_ssa feature
- optimize f2fs_enable_checkpoint() to avoid long delay
- optimize f2fs_overwrite_io() for f2fs_iomap_begin
- optimize NAT block loading during checkpoint write
- add write latency stats for NAT and SIT blocks in
f2fs_write_checkpoint
- pin files do not require sbi->writepages lock for ordering
- avoid f2fs_map_blocks() for consecutive holes in readpages
- flush plug periodically during GC to maximize readahead effect
- add tracepoints to catch lock overheads
- add several sysfs entries to tune internal lock priorities
Fixes:
- fix lock priority inversion issue
- fix incomplete block usage in compact SSA summaries
- fix to show simulate_lock_timeout correctly
- fix to avoid mapping wrong physical block for swapfile
- fix IS_CHECKPOINTED flag inconsistency issue caused by
concurrent atomic commit and checkpoint writes

…l/git/clk/linux
Pull clk updates from Stephen Boyd:
"Not much changed in the clk framework this time except the clk.h
consumer API moved the context saving APIs around to fix a build error
in certain configurations.
There was a change to the core framework for CLK_OPS_PARENT_ENABLE
behavior during registration, but it wrecked existing drivers that
didn't expect things to be turned off during clk registration so it
got reverted.
This cycle is really a large collection of new clk drivers, primarily
for Qualcomm SoCs but also for Amlogic, SpacemiT, Google, and Aspeed.
Another big change in here is support for automatic hardware clock
gating on Samsung SoCs where the clks turn on and off when needed.
Ideally more vendors move to this method for better power savings. The
highlights are in the updates section below.
Beyond all the new drivers we have a bunch of cleanups like converting
drivers from divider_round_rate() to divider_determine_rate() and
using scoped for each OF child loops. Otherwise it's the usual data
fixes and plugging reference leaks, etc. that's all pretty ordinary
but not critical enough to fix until the next release.
New Drivers:
- Qualcomm Kaanapali global, tcsr, rpmh, display, gpu, camera, and
video clk controllers
- Qualcomm SM8750 camera clk controllers
- Qualcomm MSM8940 and SDM439 global clk controllers
- Google GS101 Display Process Unit (DPU) clk controllers
- SpacemiT K3 clk controllers
- Amlogic t7 clk controllers
- Aspeed AST2700 clk controllers
Updates:
- Convert clock dividers from round_rate() to determine_rate()
- Fix sparse warnings, kernel-doc warnings, and plug leaked OF refs
- Automatic hardware clk gating on Google GS101 SoCs
- Amlogic s4 video clks
- CAN-FD clks and resets on Renesas RZ/T2H, RZ/N2H, RZ/V2H, and
RZ/V2N
- Expanded Serial Peripheral Interface (xSPI) clocks and resets on
Renesas RZ/T21H and RZ/N2H
- DMAC, interrupt controller (ICU), SPI, and thermal (TSU) clocks and
resets on Renesas RZ/V2N
- More serial (RSCI) clocks and resets on Renesas RZ/V2H and RZ/V2N
- CPU frequency scaling on T-HEAD TH1520"
