Previous commits removed all the original CRC kconfig help text, since
it was oriented towards people configuring the kernel, and the options
are no longer user-selectable. However, it's still useful for there to
be help text for kernel developers. Add this.

git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm
Pull MM updates from Andrew Morton:
- The series "Enable strict percpu address space checks" from Uros
Bizjak uses x86 named address space qualifiers to provide
compile-time checking of percpu area accesses.
This has caused a small amount of fallout - two or three issues were
reported. In all cases the calling code was found to be incorrect.
- The series "Some cleanup for memcg" from Chen Ridong implements some
relatively monir cleanups for the memcontrol code.
- The series "mm: fixes for device-exclusive entries (hmm)" from David
Hildenbrand fixes a boatload of issues which David found then using
device-exclusive PTE entries when THP is enabled. More work is
needed, but this makes thins better - our own HMM selftests now
succeed.
- The series "mm: zswap: remove z3fold and zbud" from Yosry Ahmed
remove the z3fold and zbud implementations. They have been deprecated
for half a year and nobody has complained.
- The series "mm: further simplify VMA merge operation" from Lorenzo
Stoakes implements numerous simplifications in this area. No runtime
effects are anticipated.
- The series "mm/madvise: remove redundant mmap_lock operations from
process_madvise()" from SeongJae Park rationalizes the locking in the
madvise() implementation. Performance gains of 20-25% were observed
in one MADV_DONTNEED microbenchmark.
- The series "Tiny cleanup and improvements about SWAP code" from
Baoquan He contains a number of touchups to issues which Baoquan
noticed when working on the swap code.

behaviors" from SeongJae Park fixes a few issues with the accuracy of
kdamond's walking of DAMON regions.
- The series "expose mapping wrprotect, fix fb_defio use" from Lorenzo
Stoakes changes the interaction between framebuffer deferred-io and
core MM. No functional changes are anticipated - this is preparatory
work for the future removal of page structure fields.
- The series "mm/damon: add support for hugepage_size DAMOS filter"
from Usama Arif adds a DAMOS filter which permits the filtering by
huge page sizes.
- The series "mm: permit guard regions for file-backed/shmem mappings"
from Lorenzo Stoakes extends the guard region feature from its
present "anon mappings only" state. The feature now covers shmem and
file-backed mappings.
- The series "mm: batched unmap lazyfree large folios during
reclamation" from Barry Song cleans up and speeds up the unmapping
for pte-mapped large folios.
- The series "reimplement per-vma lock as a refcount" from Suren
Baghdasaryan puts the vm_lock back into the vma. Our reasons for
pulling it out were largely bogus and that change made the code more
messy. This patchset provides small (0-10%) improvements on one
microbenchmark.
- The series "Docs/mm/damon: misc DAMOS filters documentation fixes and
improves" from SeongJae Park does some maintenance work on the DAMON
docs.

Brendan Jackman fixes a pile of unrelated issues which Brendan
encountered while runnimg our selftests.
- The series "fs/proc/task_mmu: add guard region bit to pagemap" from
Lorenzo Stoakes permits userspace to use /proc/pid/pagemap to
determine whether a particular page is a guard page.
- The series "mm, swap: remove swap slot cache" from Kairui Song
removes the swap slot cache from the allocation path - it simply
wasn't being effective.
- The series "mm: cleanups for device-exclusive entries (hmm)" from
David Hildenbrand implements a number of unrelated cleanups in this
code.
- The series "mm: Rework generic PTDUMP configs" from Anshuman Khandual
implements a number of preparatoty cleanups to the GENERIC_PTDUMP
Kconfig logic.
- The series "mm/damon: auto-tune aggregation interval" from SeongJae
Park implements a feedback-driven automatic tuning feature for
DAMON's aggregation interval tuning.

powerpc, sparc and x86 lazy MMU implementations. Ryan did this in
preparation for implementing lazy mmu mode for arm64 to optimize
vmalloc.

many threads should be used to allocate huge pages" from Thomas
Prescher does that. It allows the careful operator to significantly
reduce boot time by tuning the parallalization of huge page
initialization.
- The series "Fix calculations in trace_balance_dirty_pages() for cgwb"
from Tang Yizhou fixes the tracing output from the dirty page
balancing code.

and intuitive" from SeongJae Park improves the handling of allow and
reject filters. Behaviour is made more consistent and the documention
is updated accordingly.
- The series "Switch zswap to object read/write APIs" from Yosry Ahmed
updates zswap to the new object read/write APIs and thus permits the
removal of some legacy code from zpool and zsmalloc.
- The series "Some trivial cleanups for shmem" from Baolin Wang does as
it claims.
- The series "fs/dax: Fix ZONE_DEVICE page reference counts" from
Alistair Popple regularizes the weird ZONE_DEVICE page refcount
handling in DAX, permittig the removal of a number of special-case
checks.
- The series "refactor mremap and fix bug" from Lorenzo Stoakes is a
preparatoty refactoring and cleanup of the mremap() code.
- The series "mm: MM owner tracking for large folios (!hugetlb) +
CONFIG_NO_PAGE_MAPCOUNT" from David Hildenbrand reworks the manner in
which we determine whether a large folio is known to be mapped
exclusively into a single MM.

Zi Yan reworks the code to split a folio into smaller folios. The
main benefit is lessened memory consumption: fewer post-split folios
are generated.
- The series "Minimize xa_node allocation during xarry split" from Zi
Yan reduces the number of xarray xa_nodes which are generated during
an xarray split.

It turns out the code to generate the x86 cpufeaturemasks.h header was
way too aggressive, and would re-generate it whenever the timestamp on
the kernel config file changed.
Now, the regular 'make *config' tools are fairly careful to not rewrite
the kernel config file unless the contents change, but other usecases
aren't that careful.
Michael Kelley reports that 'make-kpkg' ends up doing "make syncconfig"
multiple times in prepping to build, and will modify the config file in
the process (and then modify it back, but by then the timestamps have
changed).
Jakub Kicinski reports that the netdev CI does something similar in how
it generates the config file in multiple steps.
In both cases, the config file timestamp updates then cause the
cpufeaturemasks.h file to be regenerated, and that in turn then causes
lots of unnecessary rebuilds due to all the normal dependencies.
Fix it by using our 'filechk' infrastructure in the Makefile to generate
the header file. That will only write a new version of the file if the
contents of the file have actually changed.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull ring-buffer updates from Steven Rostedt:
- Restructure the persistent memory to have a "scratch" area
Instead of hard coding the KASLR offset in the persistent memory by
the ring buffer, push that work up to the callers of the persistent
memory as they are the ones that need this information. The offsets
and such is not important to the ring buffer logic and it should not
be part of that.
A scratch pad is now created when the caller allocates a ring buffer
from persistent memory by stating how much memory it needs to save.
- Allow where modules are loaded to be saved in the new scratch pad
Save the addresses of modules when they are loaded into the
persistent memory scratch pad.
- A new module_for_each_mod() helper function was created
With the acknowledgement of the module maintainers a new module
helper function was created to iterate over all the currently loaded
modules. This has a callback to be called for each module. This is
needed for when tracing is started in the persistent buffer and the
currently loaded modules need to be saved in the scratch area.
- Expose the last boot information where the kernel and modules were
loaded
The last_boot_info file is updated to print out the addresses of
where the kernel "_text" location was loaded from a previous boot, as
well as where the modules are loaded. If the buffer is recording the
current boot, it only prints "# Current" so that it does not expose
the KASLR offset of the currently running kernel.
- Allow the persistent ring buffer to be released (freed)
To have this in production environments, where the kernel command
line can not be changed easily, the ring buffer needs to be freed
when it is not going to be used. The memory for the buffer will
always be allocated at boot up, but if the system isn't going to
enable tracing, the memory needs to be freed. Allow it to be freed
and added back to the kernel memory pool.
- Allow stack traces to print the function names in the persistent
buffer
Now that the modules are saved in the persistent ring buffer, if the
same modules are loaded, the printing of the function names will
examine the saved modules. If the module is found in the scratch area
and is also loaded, then it will do the offset shift and use kallsyms
to display the function name. If the address is not found, it simply
displays the address from the previous boot in hex.

Pull perf tools updates from Namhyung Kim:
"perf record:
- Introduce latency profiling using scheduler information.
The latency profiling is to show impacts on wall-time rather than
cpu-time. By tracking context switches, it can weight samples and
find which part of the code contributed more to the execution
latency.
The value (period) of the sample is weighted by dividing it by the
number of parallel execution at the moment. The parallelism is
tracked in perf report with sched-switch records. This will reduce
the portion that are run in parallel and in turn increase the
portion of serial executions.
For now, it's limited to profile processes, IOW system-wide
profiling is not supported. You can add --latency option to enable
this.
$ perf record --latency -- make -C tools/perf
I've run the above command for perf build which adds -j option to
make with the number of CPUs in the system internally. Normally
it'd show something like below:
$ perf report -F overhead,comm
...
#
# Overhead Command
# ........ ...............
#
78.97% cc1
6.54% python3
4.21% shellcheck
3.28% ld
1.80% as
1.37% cc1plus
0.80% sh
0.62% clang
0.56% gcc
0.44% perl
0.39% make
...
The cc1 takes around 80% of the overhead as it's the actual
compiler. However it runs in parallel so its contribution to
latency may be less than that. Now, perf report will show both
overhead and latency (if --latency was given at record time) like
below:
$ perf report -s comm
...
#
# Overhead Latency Command
# ........ ........ ...............
#
78.97% 48.66% cc1
6.54% 25.68% python3
4.21% 0.39% shellcheck
3.28% 13.70% ld
1.80% 2.56% as
1.37% 3.08% cc1plus
0.80% 0.98% sh
0.62% 0.61% clang
0.56% 0.33% gcc
0.44% 1.71% perl
0.39% 0.83% make
...
You can see latency of cc1 goes down to around 50% and python3 and
ld contribute a lot more than their overhead. You can use --latency
option in perf report to get the same result but ordered by
latency.
$ perf report --latency -s comm
perf report:
- As a side effect of the latency profiling work, it adds a new
output field 'latency' and a sort key 'parallelism'. The below is a
result from my system with 64 CPUs. The build was well-parallelized
but contained some serial portions.
$ perf report -s parallelism
...
#
# Overhead Latency Parallelism
# ........ ........ ...........
#
16.95% 1.54% 62
13.38% 1.24% 61
12.50% 70.47% 1
11.81% 1.06% 63
7.59% 0.71% 60
4.33% 12.20% 2
3.41% 0.33% 59
2.05% 0.18% 64
1.75% 1.09% 9
1.64% 1.85% 5
...
- Support Feodra mini-debuginfo which is a LZMA compressed symbol
table inside ".gnu_debugdata" ELF section.
perf annotate:
- Add --code-with-type option to enable data-type profiling with the
usual annotate output.
Instead of focusing on data structure, it shows code annotation
together with data type it accesses in case the instruction refers
to a memory location (and it was able to resolve the target data
type). Currently it only works with --stdio.
$ perf annotate --stdio --code-with-type

Pull Rust updates from Miguel Ojeda:
"Toolchain and infrastructure:
- Extract the 'pin-init' API from the 'kernel' crate and make it into
a standalone crate.
In order to do this, the contents are rearranged so that they can
easily be kept in sync with the version maintained out-of-tree that
other projects have started to use too (or plan to, like QEMU).
This will reduce the maintenance burden for Benno, who will now
have his own sub-tree, and will simplify future expected changes
like the move to use 'syn' to simplify the implementation.
- Add '#[test]'-like support based on KUnit.
We already had doctests support based on KUnit, which takes the
examples in our Rust documentation and runs them under KUnit.
Now, we are adding the beginning of the support for "normal" tests,
similar to those the '#[test]' tests in userspace Rust. For
instance:
#[kunit_tests(my_suite)]
mod tests {
#[test]
fn my_test() {
assert_eq!(1 + 1, 2);
}
}
Unlike with doctests, the 'assert*!'s do not map to the KUnit
assertion APIs yet.
- Check Rust signatures at compile time for functions called from C
by name.
In particular, introduce a new '#[export]' macro that can be placed
in the Rust function definition. It will ensure that the function
declaration on the C side matches the signature on the Rust
function:
#[export]
pub unsafe extern "C" fn my_function(a: u8, b: i32) -> usize {
// ...
}
The macro essentially forces the compiler to compare the types of
the actual Rust function and the 'bindgen'-processed C signature.
These cases are rare so far. In the future, we may consider
introducing another tool, 'cbindgen', to generate C headers
automatically. Even then, having these functions explicitly marked
may be a good idea anyway.
- Enable the 'raw_ref_op' Rust feature: it is already stable, and
allows us to use the new '&raw' syntax, avoiding a couple macros.
After everyone has migrated, we will disallow the macros.
- Pass the correct target to 'bindgen' on Usermode Linux.
- Fix 'rusttest' build in macOS.
'kernel' crate:
- New 'hrtimer' module: add support for setting up intrusive timers
without allocating when starting the timer. Add support for
'Pin<Box<_>>', 'Arc<_>', 'Pin<&_>' and 'Pin<&mut _>' as pointer
types for use with timer callbacks. Add support for setting clock
source and timer mode.
- New 'dma' module: add a simple DMA coherent allocator abstraction
and a test sample driver.
- 'list' module: make the linked list 'Cursor' point between
elements, rather than at an element, which is more convenient to us
and allows for cursors to empty lists; and document it with
examples of how to perform common operations with the provided
methods.
- 'str' module: implement a few traits for 'BStr' as well as the
'strip_prefix()' method.
- 'sync' module: add 'Arc::as_ptr'.
- 'alloc' module: add 'Box::into_pin'.
- 'error' module: extend the 'Result' documentation, including a few
examples on different ways of handling errors, a warning about
using methods that may panic, and links to external documentation.
'macros' crate:
- 'module' macro: add the 'authors' key to support multiple authors.
The original key will be kept until everyone has migrated.
Documentation:
- Add error handling sections.
MAINTAINERS:
- Add Danilo Krummrich as reviewer of the Rust "subsystem".
- Add 'RUST [PIN-INIT]' entry with Benno Lossin as maintainer. It has

Pull bpf try_alloc_pages() support from Alexei Starovoitov:
"The pull includes work from Sebastian, Vlastimil and myself with a lot
of help from Michal and Shakeel.
This is a first step towards making kmalloc reentrant to get rid of
slab wrappers: bpf_mem_alloc, kretprobe's objpool, etc. These patches
make page allocator safe from any context.
Vlastimil kicked off this effort at LSFMM 2024:
https://lwn.net/Articles/974138/
and we continued at LSFMM 2025:
https://lore.kernel.org/all/CAADnVQKfkGxudNUkcPJgwe3nTZ=xohnRshx9kLZBTmR_E1DFEg@mail.gmail.com/
Why:
SLAB wrappers bind memory to a particular subsystem making it
unavailable to the rest of the kernel. Some BPF maps in production
consume Gbytes of preallocated memory. Top 5 in Meta: 1.5G, 1.2G,
1.1G, 300M, 200M. Once we have kmalloc that works in any context BPF
map preallocation won't be necessary.
How:
Synchronous kmalloc/page alloc stack has multiple stages going from
fast to slow: cmpxchg16 -> slab_alloc -> new_slab -> alloc_pages ->
rmqueue_pcplist -> __rmqueue, where rmqueue_pcplist was already
relying on trylock.
This set changes rmqueue_bulk/rmqueue_buddy to attempt a trylock and
return ENOMEM if alloc_flags & ALLOC_TRYLOCK. It then wraps this
functionality into try_alloc_pages() helper. We make sure that the
logic is sane in PREEMPT_RT.
End result: try_alloc_pages()/free_pages_nolock() are safe to call
from any context.
try_kmalloc() for any context with similar trylock approach will
follow. It will use try_alloc_pages() when slab needs a new page.
Though such try_kmalloc/page_alloc() is an opportunistic allocator,
this design ensures that the probability of successful allocation of
small objects (up to one page in size) is high.
Even before we have try_kmalloc(), we already use try_alloc_pages() in
BPF arena implementation and it's going to be used more extensively in
BPF"

Pull bpf relisient spinlock support from Alexei Starovoitov:
"This patch set introduces Resilient Queued Spin Lock (or rqspinlock
with res_spin_lock() and res_spin_unlock() APIs).
This is a qspinlock variant which recovers the kernel from a stalled
state when the lock acquisition path cannot make forward progress.
This can occur when a lock acquisition attempt enters a deadlock
situation (e.g. AA, or ABBA), or more generally, when the owner of the
lock (which we’re trying to acquire) isn’t making forward progress.
Deadlock detection is the main mechanism used to provide instant
recovery, with the timeout mechanism acting as a final line of
defense. Detection is triggered immediately when beginning the waiting
loop of a lock slow path.
Additionally, BPF programs attached to different parts of the kernel
can introduce new control flow into the kernel, which increases the
likelihood of deadlocks in code not written to handle reentrancy.
There have been multiple syzbot reports surfacing deadlocks in
internal kernel code due to the diverse ways in which BPF programs can
be attached to different parts of the kernel. By switching the BPF
subsystem’s lock usage to rqspinlock, all of these issues are
mitigated at runtime.
This spin lock implementation allows BPF maps to become safer and
remove mechanisms that have fallen short in assuring safety when
nesting programs in arbitrary ways in the same context or across
different contexts.
We run benchmarks that stress locking scalability and perform
comparison against the baseline (qspinlock). For the rqspinlock case,
we replace the default qspinlock with it in the kernel, such that all
spin locks in the kernel use the rqspinlock slow path. As such,
benchmarks that stress kernel spin locks end up exercising rqspinlock.
More details in the cover letter in commit 6ffb9017e932 ("Merge branch
'resilient-queued-spin-lock'")"

"Here's the pile of clk driver patches. The usual suspects^Wsilicon
vendors are all here, adding new SoC support and fixing existing code.
There are a few patches to the clk framework here as well. They've
been baking in linux-next for weeks so I'm hoping we don't have to
revert them. The disable OF node patch is probably the scariest one
although it seems unlikely that a system would be relying on a driver
_not_ probing because the clk never appeared, but you never know.
Nothing looks out of the ordinary on the driver side but that's
because it's mostly a bunch of data.

- Use dev_err_probe() in the clk registration path (Peering into the
crystal ball shows many patches that remove printks)
- Check for disabled OF nodes in of_clk_get_hw_from_clkspec()

- Various fixes to SoC clk drivers for incorrect data, avoid touching

This fixes recursive subvolume removal.
Subvolume deletion is asynchronous; fs_path_parent, and thus the entry
in the subvolume_children btree, need to be cleared when the subvolume
is unlinked from the fs heirarchy - else we'll spuriously think a
subvolume has children and deletion will fail.

Pull LED updates from Lee Jones:
- pca955x: Add HW blink support, utilizing PWM0. It supports one
frequency across all blinking LEDs and falls back to software blink
if different frequencies are requested.
- trigger: netdev: Allow configuring LED blink interval via .blink_set
even when HW offload (.hw_control) is enabled.
- led-core: Fix a race condition where a quick LED_OFF followed by
another brightness set could leave the LED off incorrectly,
especially noticeable after the introduction of the ordered
workqueue.
- qcom-lpg: Add support for 6-bit PWM resolution alongside the existing
9-bit support.
- qcom-lpg: Fix PWM value capping to respect the selected resolution
(6-bit or 9-bit) for normal PWMs.
- qcom-lpg: Fix PWM value capping to respect the selected resolution
for Hi-Res PWMs.
- qcom-lpg: Fix calculation of the best period for Hi-Res PWMs to
prevent requested duty cycles from exceeding the maximum allowed by
the selected resolution.
- st1202: Add a check for the error code returned by devm_mutex_init().
- pwm-multicolor: Add a check for the return value of
fwnode_property_read_u32().
- st1202: Ensure hardware initialization (st1202_setup) happens before
DT node processing (st1202_dt_init).
- Kconfig: leds-st1202: Add select LEDS_TRIGGER_PATTERN as it's
required by the driver.
- lp8860: Drop unneeded explicit assignment to REGCACHE_NONE.
- pca955x: Refactor code with helper functions and rename some
functions/variables for clarity.
- pca955x: Pass driver data pointers instead of the I2C client to
helper functions.
- pca955x: Optimize probe LED selection logic to reduce I2C operations.
- pca955x: Revert the removal of pca95xx_num_led_regs() (renaming it to
pca955x_num_led_regs) as it's needed for HW blink support.
- st1202: Refactor st1202_led_set() to use the !! operator for boolean
conversion.
- st1202: Minor spacing and proofreading edits in comments.
- Directory Rename: Rename the drivers/leds/simple directory to
drivers/leds/simatic as the drivers within are not simple.
- mlxcpld: Remove unused include of acpi.h.
- nic78bx: Tidy up the ACPI ID table (remove ACPI_PTR, use
mod_devicetable.h, remove explicit driver_data initializer).
- tlc591xx: Convert text binding to YAML format, add child node
constraints, and fix typos/formatting in the example.
- qcom-lpg: Document the qcom,pm8937-pwm compatible string as a
fallback for qcom,pm8916-pwm.
