ASoC: Fixes for v7.3
A fairly big batch of fixes that came in during the merge window. There's a lot of quirks for x86 systems and a bunch of driver specific fixes, the most critical being the fixes for Tegra's register definitions. It turned out that they had been relying on the regmap default handling bugs that were fixed in v7.2 and so audio was fairly badly broken, unfortunately the issue wasn't noticed in time for release. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmqQONIACgkQJNaLcl1U h9Dzbgf+OYlkheBcs0+Go3wKN+5JEQBCQl3vjbAbR9bq2XXEUTR5SNIIjAgG7YfS XRFc91Nfx9mwqW8y128ITZ09Ao1xQKjSrzaa0WxSIjR2gx2WJMMhwGdFNvH/fehf JKoIRXJ4qYXalfrrqXiTMFJHfSaZxDoDbMg+2Wipqi/xOuWWO+1eDNW0dnmkF422 stpXIShNh7ljlcBgpH6ts3ZpkPkwRcVOpFrBsqtbFcTAlw1XbMwjHAPYVSHm03wt 5dpIZd4b2XA51zqH3z8RTlX+0U2xDilAMU3K74qyzxKPAi9I8FahoKPu5H7kMa77 6ly9hBSmcOWnRb9mXfhY8GxXaxXDIA== =T5wt -----END PGP SIGNATURE----- Merge tag 'asoc-fix-v7.3-merge-window' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Fixes for v7.3 A fairly big batch of fixes that came in during the merge window.

ALSA: control: Don't add invalid kcontrols to LED layer
The kcontrol LED state layer tries to track the all associated
kcontrol elements with naive assumptions that they are readable.
But one can create a write-only element that has no get callback (even
a user element can do it), and this may lead to a NULL dereference at
the call chain of snd_ctl_led_notify(), as found by syzkaller.
For avoiding the Oops, add a sanity check of the kcontrol's info and
get callbacks, and just skip the invalid kcontrols before assigning
the kctl to the LED layer.
Reported-by: syzbot+b7fe2760ea6f1ee44b4d@syzkaller.appspotmail.com

ASoC: dapm: Fix off-by-one check on the second enum channel
The snd_soc_dapm_put_enum_double() rejects item[0] once it reaches
e->items, but it lets item[1] be equal to it. Both go on to
snd_soc_enum_item_to_val(), which indexes e->values with no bound of
its own, so an enum with a value table reads one element past the end.
The indexing arrived with the MUX consolidation, which relaxed the
item[1] check in the same hunk. The value MUX handler it deleted used
>= there, and the snd_soc_put_enum_double() in soc-ops.c still does.
Only adav80x pairs a value table with two shifts, and its second
channel looks accidental, but the control does report two values.
Writing three into it reads off the end of adav80x_mux_values. The
core catches that only under CONFIG_SND_CTL_INPUT_VALIDATION, which
defaults off.

ASoC: amd: acp-config: force SoundWire probe on HP OmniBook X Flip 16
The BIOS on the HP OmniBook X Flip 16-cc0xxx (board 8EA2) reports acp-audio-config-flag = FLAG_AMD_LEGACY_ONLY_DMIC. This binds the legacy ACP driver and registers a PDM-only card, so the SoundWire links are never scanned and the two TAS2783 speaker amplifiers and RT712-VB codec do not enumerate. Add a DMI entry for board 8EA2 to the ACP70 ACPI flag override table so the firmware-provided flag is overridden and snd_pci_ps probes instead. On the affected system, an otherwise identical upstream kernel without this entry binds snd_acp_pci, enumerates no SoundWire slave devices and exposes no internal speaker PCM. With the entry added, snd_pci_ps binds, both TAS2783 amplifiers and the RT712-VB enumerate over SoundWire, and the amd-soundwire card exposes the internal speaker playback PCM. Developed with AI assistance. ChatGPT helped analyze the ACP and SoundWire behavior, structure the controlled A/B testing, and draft the patch changelog. All hardware measurements, kernel builds, reboots and playback tests were performed by the submitter. The submitter has reviewed the change, understands it and takes responsibility for it.

ASoC: soc-generic-dmaengine: Fix DMA channel request warning
The DMA channel request code currently warns about legacy DMA failures
when the channel name is not present in dma-names. This can report a
firmware lookup failure as a legacy DMA failure.
Furthermore, failures from the legacy DMA path are already reported by
find_candidate(), making these warnings redundant.
Only warn when the channel name is present in dma-names but the request
fails, avoiding misleading and duplicate error messages.

Char/Misc/IIO/etc driver update for 7.3-rc1
Here is the big set of char, misc, iio, counter, fpga, and other small
driver subsystems for 7.3-rc1.
Overall, due to some driver removals we only added a bit more code than
removed, which was a nice change. Highlights in this merge request are:
- Loads of IIO driver updates and additions
- binder driver updates (more on that below...)
- Removal of the SGI XP and GRU drivers as they are not used anymore
and turn out to be pretty insecure overall
- Removal of the obsolete ibmasm driver as it's not being used anymore
- Coresight driver updates and additions
- Mei driver udpates
- Counter driver updates
- FPGA driver updates
- ICC driver updates
- lots and lots of other tiny driver updates to resolve reported
issues
All of these have been in linux-next for a while, with the only reported
issues being some major merge conflicts. Miguel pointed out some of
these with the Rust tree merge, which is the majority of them. I'll
follow up with a diffstat of the merge resolution I made against your
most recent tree, which works for me.

ALSA: rawmidi: Another workaround for false-positive mutex lockdep warning
While we attempted to work around the false-positive lockdep warning
due to the nested mutex lock in rawmidi at the open path for a UMP
legacy rawmidi, it didn't cover the similar locking at its close path,
and this still caused another false-positive reports by syzkaller.
Add a similar workaround to snd_rawmidi_kernel_release() as done in
the former commit

ALSA: hda/realtek: Fix speaker mute LED for HP Laptop 15-fd0039nt
HP Laptop 15-fd0039nt (SSID 103c:8bb6) needs a quirk to control the
speaker mute LED via VREF100 on NID 0x1a (active-high).
This patch replaces the previous ALC236_FIXUP_HP_MICMUTE_LED_ONLY
with ALC236_FIXUP_HP_15_FD0XXX, which covers both mic mute (GPIO0)
and speaker mute (NID 0x1a) LEDs.
Use spec->no_shutup_pins instead of a custom shutup hook, as suggested
by Takashi Iwai.

ALSA: usb-audio: Complete cleanup after system-resume errors
A failed system resume can leave the card unusable until reboot. usb_audio_resume() jumps to err_out when snd_usb_pcm_resume() or snd_usb_mixer_resume() fails. The error path skips the out: block, which restores D0 and decrements chip->num_suspended_intf. The card stays in SNDRV_CTL_POWER_D3hot, so later control access blocks in snd_power_ref_and_wait(). USB core logs an interface resume callback error. It does not retry that callback, so a later callback cannot complete the skipped cleanup. usb_audio_suspend() increments num_suspended_intf before returning success. A system-resume callback must consume the system-suspend count even if a component resume fails. Otherwise, the stranded count skews later suspend and resume cycles. Do not apply this cleanup to runtime-resume errors. Runtime PM can retry -EAGAIN or -EBUSY without another suspend callback. The count must continue to describe that suspended interface. Other runtime-resume errors latch runtime_error in the PM core and do not cause an immediate callback retry. Both parts of the system-resume error path are longstanding. Commit |

ALSA: usb-audio: Skip mixer creation on M-Audio Venom
The M-Audio Venom (0763:2084) does not answer any GET_CUR request of its feature units, hanging up the USB microcontroller and "responding" with timeouts. So the mixer building lasts around 47 seconds, and the device does not stream at all. The same GET_CUR requests issued through libusb (with no kernel driver bound) complete correctly and blazingly fast. So it seems to only happen during the initial probe. I defined an explicit composite quirk to bypass the mixer creation, as it is not needed (the synth already comes with volume controls). With both this and the device flag applied, the synth works flawlessly.

ALSA: usb-audio: Skip reading sample rate on M-Audio Venom
The M-Audio Venom (0763:2084) is an USB Audio Class 1 compliant synth with an integrated audio interface, it does not implement GET_CUR on SAMPLING_FREQ_CONTROL, hanging up if requested on endpoint 0. The first class request issued by the driver after enumeration is a GET_CUR on endpoint 0x02, freezing the device's USB microcontroller. Timing out on every transfer afterwards with -ETIMEDOUT, such as SET_INTERFACE, so neither the mixer nor any streaming interface is set up. Analyzing a USBPcap capture of the Windows driver I found it never requests the sampling frequency, as the synth exposes a single discrete of 44100Hz on both streaming interfaces, thus asking for it is unnecessary. So I applied get_sample_rate to avoid this check, and disable_autosuspend because the synth doesn't come back from being suspended.

ALSA: usb-audio: fix OOB write in snd_usbmidi_novation_output()
snd_usbmidi_novation_output() lays out a two-byte header at transfer_buffer[0..1] and passes &transfer_buffer[2] together with a length of ep->max_transfer - 2 to snd_rawmidi_transmit(): count = snd_rawmidi_transmit(ep->ports[0].substream, &transfer_buffer[2], ep->max_transfer - 2); ep->max_transfer comes from the output endpoint's wMaxPacketSize via usb_maxpacket(). A malformed or malicious device can advertise a bulk OUT endpoint with a wMaxPacketSize of 1 - the USB core only clamps this value downwards - so ep->max_transfer becomes 1 and the count argument becomes -1. snd_rawmidi_transmit() passes the negative count on to __snd_rawmidi_transmit_peek(), where "if (count1 > count) count1 = count" leaves count1 negative; get_aligned_size() keeps it negative for a byte-stream substream, so the following memcpy(buffer, ..., count1) runs with a (size_t)-1 length and writes far past the transfer buffer, which was allocated with usb_alloc_coherent(ep->max_transfer). This is the same class of bug that was fixed for snd_usbmidi_akai_output() in commit |

ALSA: usb-audio: Add iD14 MkI to monitor-mix volume quirk
Add the iD14 MkI USB ID to the existing audient_id14_map. This names feature unit 12 Monitor Mix Playback Volume. Live meter A/B testing on MkI USB ID 2708:0002 reproduced the same asymmetric attenuation seen on MkII. At ALSA value 104, the right channel was 23.07 dB below the left. At 127, both channels were equal. The misleading Speaker Playback Volume name causes PipeWire to adopt FU12 as the stream master. Reuse the existing map to keep the control available while preventing that selection. Hardware-tested on Bazzite 7.2.0-ogc4.1.fc44.x86_64 with this change backported. ALSA exposed Monitor Mix Playback Volume after module load and USB reconnect. PipeWire volume changes from 100% to 35% and back left all four FU12 values at 127. Channel-isolated left/right playback remained balanced after reconnect. Build-tested with CONFIG_SND_USB_AUDIO=m using the focused sound/usb target.

ALSA: usb-audio: Add quirk flags for Logitech PRO X Wireless
The Logitech PRO X Wireless is a wireless headset with a hotpluggable microphone. Its Playback mixer's GET_CUR somehow becomes broken when the microphone is detached, so set QUIRK_FLAG_MIXER_GET_CUR_OK to prevent the mixer behavior from depending on whether the microphone is attached. Meanwhile, the Playback mixer's minimum value doesn't work properly, thus set QUIRK_FLAG_MIXER_PLAYBACK_MIN_MUTE to prevent userspace audio stack from using the minimum mixer value to tune volume (setting it when muted is OK).

ALSA: usb-audio: Reverse MIXER_GET_CUR_BROKEN as MIXER_GET_CUR_OK
The default behavior of sticky check now becomes what QUIRK_FLAG_MIXER_GET_CUR_BROKEN originally does, so the quirk flag is no longer needed. On some devices, whether their GET_CUR being sticky depends on whether hotpluggable components are present. When the hotpluggable components are missing on probe, their GET_CUR behavior is classified as broken. Therefore, reverse QUIRK_FLAG_MIXER_GET_CUR_BROKEN as QUIRK_FLAG_MIXER_GET_CUR_OK, so that it can be set to prevent the heuristics from gating GET_CUR. Note that even if the quirk flag is set, init_cur_mix_raw() should still initialize the mixer value to cval->min, otherwise restoring the bogus saved value on the first channel could lead to unbalanced channels.

ALSA: usb-audio: Demote the severity of sticky GET_CUR
Currently, a mixer is disabled when its GET_CUR is sticky, causing userspace to fall back to soft mixers, unless QUIRK_FLAG_MIXER_GET_CUR_BROKEN is set. This leads to issues on some wireless headphones with broken GET_CUR but effective SET_CUR, which use poorly-performed lossy codecs and are prone to audible distortion at low volume. They have to set the quirk flag to reeanble the mixer. Considering that users can always opt into soft mixers if they need it, i.e., when SET_CUR is stubbed, demote the severity of sticky GET_CUR by marking GET_CUR as broken and only provide mixer values from the cache. The mixer itself is still registered.

ALSA: hda/realtek: Fix ALC700 audio on Intel Hades Canyon
On Intel Hades Canyon systems with an ALC700 codec, analog audio can become unusable after rebooting from Windows into Linux. The affected system uses codec subsystem ID 8086:2073. In the broken state, Realtek coefficient 0x1b has value 0x4a4b. Setting bit 0x0400 changes it to 0x4e4b and immediately restores normal analog playback. The BIOS also sets this bit after disabling and re-enabling onboard audio, while Windows may leave it cleared. Linux currently does not restore it during codec initialization. Add a machine-specific fixup for Intel Hades Canyon which sets only bit 0x0400 of coefficient 0x1b during HDA_FIXUP_ACT_INIT. The fix has been verified across Windows -> Linux reboots on an Intel NUC8i7HNB with an ALC700 codec.

Summary of patch series in this merge:
- The 2 patch series "mm: drop "sub" prefix from various places" from
Dev Jain implements some page->folio conversion and a naming cleanup.
- The 2 patch series "mm/kasan: remove redundant initialization for
kasan_flag_write_only" from Igor Putko provides some KASAN cleanup work.
- The 2 patch series "mm/filemap: reduce unnecessary xarray lookups"
from Chi Zhiling provides a small speedup in the pagecaache read code.
- The 4 patch series "mm/percpu: Fix possible NOFS/NOIO reclaim
recursion" from Kaitao Cheng improves a few things in the vmalloc code -
mainly the avoidance of GFP_KERNEL allocations when the caller asked for
GFP_NOFS or GFP_NOIO.
- The 3 patch series "mm/kmemleak: avoid soft lockup when scanning task
stacks" from Breno Leitao avoids a soft lockup watchdog trigger from the
kmemleak scanning code in extreme situations.
- The 6 patch series "mm/page_owner: misc cleanups" from Ye Liu is a
collection of unrelated cleanups to the page_owner code. For some
reason lots of people have been working on the page_owner code this
cycle.
- The 4 patch series "mm: convert to walk_page_range_vma() to eliminate
find_vma()" from Kefeng Wang simplifies and accelerates the page walking
library function.
- The 3 patch series "mm/migrate: preparatory cleanups for batch copy
and offload" from Shivank Garg implements cleanups in the migration
code.
- The 4 patch series "mm/page_owner: add per-fd filter infrastructure
for print_mode and NUMA filtering" from Zhen Ni provides per-fd
filtering to page_owner in order to reduce the sometimes vast amount of
output it can produce.
- The 19 patch series "mm: Refactor bootmem gigantic hugepage
allocation" from Muchun Song is a "set of fixes and preparatory cleanups
around bootmem HugeTLB handling, sparse initialization ordering, and
related vmemmap setup".
- The 4 patch series "mm/zsmalloc: reduce lock contention in zs_free()"
from Wenchao Hao reduces lock contention in zs_free(), which dominates
the unmap path under memory pressure on Android (LMK kills) and on x86
servers running zswap-heavy workloads. Up to 1.83x improvement in
microbenchmarking.
- The 2 patch series "move alloc_tag.c file under mm/" from Suren
Baghdasaryan does that.
- The 6 patch series "samples/damon: handle damon_{start,stop}()
failures" from SJ Park fixes improper handling of damon_start(),
damon_stop(), and damon_call() failures across DAMON sample modules to
prevent potential memory leaks, operation disruptions and use-after-free
bugs.
- The 11 patch series "mm/damon/sysfs: kobject_del() directories that
users can create/remove" from SJ Park resolves an issue where delayed
sysfs directory removal under CONFIG_DEBUG_KOBJECT_RELEASE causes
creation failures due to duplicate directory names by adding missing
kobject_del() calls before creating new directories.
- The 3 patch series "mm: cleanup clear_not_present_full_ptes()" from
David Hildenbrand cleans up the core pte handling code.
- The 3 patch series "selftests/damon: misc fixes for test bugs" from
Kunwu Chan fixes several bugs in the DAMON selftests.
- The 2 patch series "selftests/damon: fix memcg_path staging handling"
from Cheng Nie fixes a bug in _damon_sysfs.py for damos_filter
memcg_path setup, and adds a test case for it in sysfs.py.
- The 2 patch series "selftests/damon: test kdamond refresh_ms" from
Ruslan Valiyev introduces selftest coverage for DAMON's refresh_ms sysfs
feature by updating the test control module and verifying that scheme
stats update automatically without manual intervention.
- The 5 patch series "mm/damon: five misc fixups" from Akinobu Mita
contains miscellaneous DAMON fixups.
- The 2 patch series "mm/damon/core: detect internal variation above
max_nr_regions/2" from Jiayuan Chen fixes DAMON's region splitting
behavior when region counts exceed half the maximum budget by
dynamically scaling down the split fraction as the limit approaches,
preventing large regions from staying un-split, and adds corresponding
KUnit test coverage.
- The 6 patch series "mm: preparatory patches for PMD level swap
entries" from Usama Arif refactors and cleans up PMD softleaf helpers,
call sites, and architecture flags to lay the groundwork for a follow-up
series that introduces PMD page table swap entries.
- The 11 patch series "mm/damon: update, optimize, and clean up doc,
tests, and code" from SJ Park updates DAMON design and ABI
documentation, expands unit and selftest coverage, optimizes
damon_commit_target_regions(), and cleans up recently added sysfs
interface code for better readability.
- The 2 patch series "mm/vmpressure: reduce CPU, memory and code
overhead on cgroup v2" from Usama Arif optimizes vmpressure() by
skipping unnecessary work on cgroup v2 for userspace event notifications
and refactors v1-only eventfd handling into mm/memcontrol-v1.c to reduce
memory overhead and code complexity.
- The 10 patch series "selftests/mm: refactor pkey helpers and fix mmap
error handling" from Hongfu Li refactors pkeys shared tracing and
assertion helpers into a common file, unifies protection key selftests
to use consistent diagnostic logging and assertions, and enforces
standardized MAP_FAILED return checks for mmap() calls across the tests.
- The 18 patch series "mm/damon: optimize out nr_accesses_bp" from SJ
Park replaces the error-prone, continuously updated nr_accesses_bp field
in damon_region with an on-demand moving sum function
(damon_nr_accesses_mvsum()), reducing structure memory overhead and
avoiding state corruption bugs.
- The 6 patch series "Open HugeTLB allocation routine for more generic
use" from Ackerley Tng decouples HugeTLB folio allocation from VMA

from SJ Park integrates DAMON's probe_hits attribute counter into the
pseudo moving sum infrastructure, enabling real-time, online monitoring
without waiting for full aggregation intervals.
- The 18 patch series "mm: Some cleanups for page allocator APIs" from
Brendan Jackman simplifies and refactors the page allocator entry points
and flags by unifying allocation paths, adding internal alloc_flags
arguments, and eliminating redundant __ prefixed alloc_pages variants.
- The 5 patch series "Fix incorrect access of hugetlb pte entries" from
Dev Jain enforces the consistent use of huge_ptep_get() instead of
ptep_get() for HugeTLB entries and fixes an unaligned address issue in
arm64's huge_ptep_get() implementation.
- The 8 patch series "mm/damon: validate all parameters in the core"
from SJ Park consolidates parameter validation into the DAMON core
specifically within damon_start() and damon_commit_ctx() to centralize
error checking, eliminate caller-side redundant checks and to improve
maintenance efficiency.
- The 3 patch series "tools/mm/page_owner_sort: fix filtering and
cleanup issues" from Yichong Chen renames is_need() to filter_record()
for clearer return semantics, fixes per-record allocation memory leaks
and bounds output copies in search_pattern() to address an existing
buffer issue.
- The 4 patch series "memcg: bail out reclaim when memcg is dying" from
Jiayuan Chen mitigates a system-wide stall which occurs when a cgroup is
removed while one of its memory control files is doing synchronous
reclaim.
- The 5 patch series "mm/memory-failure: add panic option for
unrecoverable pages" from Breno Leitao introduces an opt-in
vm.panic_on_unrecoverable_memory_failure sysctl that immediately panics
the kernel on unrecoverable memory errors in kernel-owned pages to
preserve error context and prevent delayed, silent data corruption.
- The 11 patch series "mm/damon: refactor damon_{start,stop,commit}()
for simple error handling" from SJ Park refactors the DAMON core API
functions to guarantee that all contexts are fully stopped when
damon_start(), damon_stop(), or damon_commit() fail, eliminating the
need for complex and error-prone caller-side cleanup code.
- The 5 patch series "Keep tail page private zero at free and folio
split" from Zi Yan adds checks to ensure tail_page->private is zero when
freeing compound or high-order pages and when promoting tail pages
during large folio splits. By validating these fields at free and split
time, it allows the removal of redundant private field clearing inside
prep_compound_tail().
- The 4 patch series "mm: drop redundant lru_add_drain in anon folio
reuse paths" from Barry Song eliminates redundant lru_add_drain() calls
in wp_can_reuse_anon_folio() and do_swap_page() to reduce LRU lock
contention and system overhead.
By validating folio refcounts against the LRU cache before draining
and removing unnecessary drains in the swap path, it achieves up to a
30.5% reduction in drain calls during heavy swap workloads.
- The 3 patch series "mm: clean up folio LRU and swap declarations" from
Jianyue Wu reorganizes folio LRU and swap code by relocating
page-cluster state to mm/swap_state.c, renaming mm/swap.c to mm/folio.c,
and moving MM-internal reclaim declarations into mm/internal.h.
- The 15 patch series "userfaultfd: working set tracking for VM guest
memory" from Kiryl Shutsemau adds userfaultfd support for tracking the
working set of VM guest memory, so a VMM can identify hot pages and
reclaim cold ones to tiered or remote storage.
- The 10 patch series "mm: remove CONFIG_HAVE_BOOTMEM_INFO_NODE (Part
2)" from David Hildenbrand removes the remaining pieces of
CONFIG_HAVE_BOOTMEM_INFO_NODE, performing some smaller cleanups around
freeing of reserved vmemmap pages on the way.
- The 7 patch series "mm/damon: update probe hits for runtime parameter
commits" from SJ Park ensures that DAMON's probe_hits attribute counter
is properly updated when monitoring intervals are changed at runtime,
matching the behavior of nr_accesses. To achieve this, it refactors and
renames existing helper functions for shared use, applies the updates to
probe_hits, and handles edge cases in damon_probe_hits_mvsum() to
maintain measurement accuracy.
- The 3 patch series "KSM: performance optimizations for rmap_walk_ksm"
from xu xin resolves a severe KSM reverse-mapping performance bottleneck
where thousands of split VMAs sharing a single anon_vma cause extended
lock contention. By adding an interval-filtering check during the rmap
walk, it reduces worst-case anon_vma lock hold times from over 500ms
down to under 2ms, preventing application freezes and latency spikes
under memory pressure.
- The 3 patch series "mm: split a couple of headers from internal.h"
from Mike Rapoport splits declarations related to mm_init, memblock,
vmalloc and sparse into new headers.
- The 2 patch series "KSM: use linear_page_index in collect_procs_ksm()"
from xu xin applies the interval tree optimization from rmap_walk_ksm()
to collect_procs_ksm() to avoid iterating over non-matching VMAs during
KSM memory error handling. It hoists loop-invariant address
initialization and restricts the anon_vma_interval_tree_foreach walk to
a targeted page offset range, reducing redundant checks and improving
lookup efficiency.
- The 3 patch series "selftests/mm: avoid false failures in hugetlb and
KSM tests" from Sayali Patil fixes issues in the hugetlb and KSM MM
selftest categories that can report failures when the prerequisites for
the tests are not satisfied.
- The 19 patch series "mm/damon: introduce data attributes only
monitoring" from SJ Park introduces attribute-weighted region management
in DAMON, allowing users to prioritize specific data attributes (such as
page sizes or cgroups) over or instead of access monitoring.
By assigning weights to attribute probes, DAMON can completely disable
access tracking and adjust monitoring regions based on weighted
probe-hit counters to optimize monitoring quality for attribute-focused
workloads.
- The 8 patch series "mm/hmm: Add mmap lock-drop support for
userfaultfd-backed mappings" from Stanislav Kinsburskii extends
hmm_range_fault() to support userfaultfd-backed regions by allowing the
mmap lock to be dropped during fault handling via a new
hmm_range_fault_locked() helper.
By accepting a locked pointer and signaling retry status when lock
release occurs, it enables page fault resolution in userfaultfd regions
while preserving backward compatibility for existing callers.
- The 33 patch series "mm: make VMA page offset handling more
consistent" from Lorenzo Stoakes cleans up and standardizes how
vma->vm_pgoff is accessed and manipulated across file-backed and
anonymous mappings in the kernel.
It introduces dedicated helper functions such as vma_start_pgoff(),
vma_end_pgoff(), vma_set_pgoff() and linear_page_delta() while renaming
rmap interval tree helpers to better reflect their functionality.
These changes establish a cleaner foundation for future work that will
unify virtual page offset indexing for all anonymous and CoW'd folios.
- The 3 patch series "mm: handle device-private PMDs in walk callbacks"
from Usama Arif addresses kernel panics and state corruption caused by
MM walk callbacks reaching non-present device-private PMD swap entries
created during HMM migrations.

recognize device-private PMDs instead of assuming a present THP or a
standard migration entry.
- The 5 patch series "mm/rmap: Refactor try_to_unmap_one" from Dev Jain
refactors try_to_unmap_one by modularizing Hugetlb, anonymous-lazyfree,
and anonymous-swapbacked logic into dedicated functions, laying the
structural groundwork for batched anonymous large folio unmapping.
- The 4 patch series "Docs/ABI/damon: sysfs ABI document fixes and
additions" from Song Hu fixes typos and fills in missing entries in the
DAMON sysfs ABI document.
- The 10 patch series "dax/kmem: atomic whole-device hotplug via sysfs"
from Gregory Price introduces an atomic sysfs state attribute and
supporting DAX/MM infrastructure to prevent userland races when
offlining and removing entire memory regions.
By adding an unplugged state alongside standard online modes, it
enables whole-device atomic hotplug control while preserving backward
compatibility.
- The 13 patch series "mm: convert more vm_flags_t users to vma_flags_t"
from Lorenzo Stoakes continues transitioning the kernel from the
deprecated vm_flags_t type to vma_flags_t across core memory management
infrastructure.
It replaces legacy type usage in core functions such as do_mmap(),
unmapped area allocation, mm->def_vma_flags, and VMA operations like
mlock, mprotect, and mremap.
- The 2 patch series "Two small patches to clean up mm/mm_slot.h" from
xu xin refactors mm_slot.h by introducing mm_slot_remove() to unify
duplicate slot deletion sequences in khugepaged and KSM. It also adds
code documentation explaining why mm_slot_lookup and mm_slot_insert must
remain as preprocessor macros rather than static inline functions.
- The 10 patch series "mm/damon/core: hide core-private struct fields"
from SJ Park cleans up DAMON core structures by consistently marking
internal-only fields with private: comment tags to prevent improper
direct access from outer layers.
It enforces encapsulation across core structures including
damon_region, damon_target, and damon_ctx and updates DAMON_SYSFS to
interact through approved access APIs instead of exposing raw struct
members.
- The 6 patch series "mm/damon: unurgent fixes for infinite loop, NULL
de-ref and races" from SJ Park addresses potential infinite loops, NULL
dereferences, and race conditions identified in DAMON.
It fixes an infinite loop triggered by extreme user configurations, a
NULL pointer dereference within unit tests and minor monitoring
accuracy degradation caused by subtle runtime races.
- The 2 patch series "mm/page_alloc: fixes for free_pages_nolock() on
RT/UP" from Brendan Jackman fixes an NMI safety flaw in
__free_frozen_pages() where freeing pages on non-SMP or PREEMPT_RT
kernels can bypass can_spin_trylock() checks via non-PCP or isolated
migration paths.
It also resolves potential kernel crashes and privilege escalation
risks triggered when BPF tracing runs in NMI context alongside memory
hotplug or large allocation frees.
- The 4 patch series "mm/page_alloc: couple of followups for recent
cleanups" from Brendan Jackman cleans up and updates page allocator
nomenclature, documentation, and debug assertions.
It aligns internal FPI_ flags with the public "nolock" naming
convention, removes outdated internal implementation details from
high-level page allocator comments, and eliminates obsolete VM_BUG_ON()
assertions in allocation paths.
- The 3 patch series "mm/mseal: further cleanups" from Lorenzo Stoakes
refactors and simplifies the mseal implementation by clarifying API
boundaries and removing unnecessary code complexity.
It replaces generic do_mseal() usage outside the syscall with a
dedicated mseal_mmap_page_zero() helper for MMAP_PAGE_ZERO, eliminates
mm_struct parameters to enforce that sealing applies only to
current->mm, and streamlines overall logic and comments with no
functional changes intended.
- The 4 patch series "mm/vmscan: fix swappiness=max and clean up
per-node proactive reclaim" from Ridong Chen resolves reclaim behavior
bugs and cleans up function parameters across memory reclaim paths.
It fixes swappiness=max in both standard reclaim and MGLRU so
unswappable anonymous memory no longer falls back to evicting page
cache, ensures reclaim_store() returns accurate error codes instead of
collapsing all failures into -EAGAIN, and removes the obsolete gfp_mask
parameter from __node_reclaim().
- The 6 patch series "mm: mincore: misc cleanups" from Kefeng Wang
cleans up and simplifies the mincore code. Most importantly, it removes
the historical special behavior that always reports VM_PFNMAP pages as
non-resident.
- The 2 patch series "mm/huge_memory: drop dead split helper variants"
from Kiryl Shutsemau implements two trivial cleanups in the folio split
API.
- The 7 patch series "mm/damon: fix uninitialized DAMOS field and kunit
exec expectation bugs" from SJ Park resolves minor operational and
testing bugs in DAMON identified by Sashiko. It initializes the
damos->last_applied field to prevent occasional efficiency degradation
and fixes invalid memory accesses in DAMON KUnit tests during test
failure handling.
- The 3 patch series "cleanup for stable_page_flags()" from Jinjiang Tu
cleans up and refactors stable_page_flags() used by /proc/kpageflags
without altering functionality.
It uses BIT_ULL() to prevent shift-overflow warnings on 64-bit flag
bits, converts folio-specific flag checks to standard folio_test_*()
helpers, and removes redundant CONFIG_PAGE_IDLE_FLAG handling.
- The 3 patch series "Batch unmap of uffd-wp file folios" from Dev Jain
extends batched folio unmapping support to file folios within
userfaultfd write-protect (uffd-wp) VMAs by adding batching capabilities
to pte_install_uffd_wp_if_needed().
This removes special-case restrictions on uffd-wp VMAs in
try_to_unmap_one(), significantly simplifying the function's control
flow and complexity.
- The 3 patch series "mm/early_ioremap: clarify and clean up
early_ioremap_reset()" from Sang-Heon Jeon clarifies and cleans up the
architecture-specific usage of __late_set_fixmap() and
__late_clear_fixmap() after early_ioremap_reset().
It adds explicit documentation regarding when early_ioremap_reset()
must be called and removes redundant macro definitions and reset calls
in the RISC-V and ARM64 architectures.
- The 4 patch series "mm: fix reclaim storms in defrag_mode" from
Johannes Weiner addresses severe performance regressions, swap storms,
and spurious OOMs caused by vm.defrag_mode=1 under high memory pressure
in Meta production.
It updates the page allocator slowpath so non-movable allocation
requests actively trigger direct reclaim and direct compaction at
pageblock_order scale, allowing them to claim whole pageblocks rather
than spinning unproductively.
- The 2 patch series "zram: lockmap tweaks" from Sebastian Siewior
optimizes and fixes lockdep tracking for zram devices by consolidating
per-entry lockmaps and isolating lock classes across multiple instances.
It reduces memory overhead by replacing per-entry lockdep_map instances
with a single map per struct zram, and assigns a dynamic lock_class_key
to each instance to prevent false deadlock reports when different zram
devices are backed by distinct filesystems.

dedicated mseal_mmap_page_zero() helper for MMAP_PAGE_ZERO,
eliminates mm_struct parameters to enforce that sealing applies only
to current->mm, and streamlines overall logic and comments with no
functional changes intended.
- "mm/vmscan: fix swappiness=max and clean up per-node proactive
reclaim" (Ridong Chen)
Resolve reclaim behavior bugs and clean up function parameters across
memory reclaim paths
It fixes swappiness=max in both standard reclaim and MGLRU so
unswappable anonymous memory no longer falls back to evicting page
cache, ensures reclaim_store() returns accurate error codes instead
of collapsing all failures into -EAGAIN, and removes the obsolete
gfp_mask parameter from __node_reclaim().
- "mm: mincore: misc cleanups" (Kefeng Wang)
Clean up and simplifies the mincore code. Most importantly, it
removes the historical special behavior that always reports VM_PFNMAP
pages as non-resident.
- "mm/huge_memory: drop dead split helper variants" (Kiryl Shutsemau)
Two trivial cleanups in the folio split API
- "mm/damon: fix uninitialized DAMOS field and kunit exec expectation
bugs" (SJ Park)
Resolve minor operational and testing bugs in DAMON identified by
Sashiko. It initializes the damos->last_applied field to prevent
occasional efficiency degradation and fixes invalid memory accesses
in DAMON KUnit tests during test failure handling.
- "cleanup for stable_page_flags()" (Jinjiang Tu)
Clean up and refactor stable_page_flags() used by /proc/kpageflags
without altering functionality.
It uses BIT_ULL() to prevent shift-overflow warnings on 64-bit flag
bits, converts folio-specific flag checks to standard folio_test_*()
helpers, and removes redundant CONFIG_PAGE_IDLE_FLAG handling.
- "Batch unmap of uffd-wp file folios" (Dev Jain)
Extend batched folio unmapping support to file folios within
userfaultfd write-protect (uffd-wp) VMAs by adding batching
capabilities to pte_install_uffd_wp_if_needed().
This removes special-case restrictions on uffd-wp VMAs in
try_to_unmap_one(), significantly simplifying the function's control
flow and complexity.
- "mm/early_ioremap: clarify and clean up early_ioremap_reset()"
(Sang-Heon Jeon)
Clarify and clean up the architecture-specific usage of
__late_set_fixmap() and __late_clear_fixmap() after
early_ioremap_reset()
It adds explicit documentation regarding when early_ioremap_reset()
must be called and removes redundant macro definitions and reset
calls in the RISC-V and ARM64 architectures.
- "mm: fix reclaim storms in defrag_mode" (Johannes Weiner)
Address severe performance regressions, swap storms, and spurious
OOMs caused by vm.defrag_mode=1 under high memory pressure in Meta
production
It updates the page allocator slowpath so non-movable allocation
requests actively trigger direct reclaim and direct compaction at
pageblock_order scale, allowing them to claim whole pageblocks rather
than spinning unproductively.
- "zram: lockmap tweaks" (Sebastian Siewior)
Optimize and fix lockdep tracking for zram devices by consolidating
per-entry lockmaps and isolate lock classes across multiple instances
This reduces memory overhead by replacing per-entry lockdep_map
instances with a single map per struct zram, and assigns a dynamic
lock_class_key to each instance to prevent false deadlock reports
when different zram devices are backed by distinct filesystems.

ALSA: hda/realtek: Reorder quirk entries for Lenovo Legion Pro 7 16ARX8H
Reorder the HDA_CODEC_QUIRK entries for 0x17aa:0x38a7 and 0x17aa:0x38a8 so that the AMD variant (TAS2781) is matched before the Intel variant's PCI SSID (0x386f) which uses a different amplifier. This ensures the correct fixup (ALC287_FIXUP_TAS2781_I2C) is applied to the AMD model, restoring internal speaker functionality.

ALSA: hda/realtek: Fix bass speaker DAC routing for Lenovo Yoga Pro 9 16IAH10
The Lenovo Yoga Pro 9 16IAH10 (PCI SSID 17aa:3846, codec SSID 17aa:3920) uses a TAS2781 smart amplifier driven via the ALC287 codec. On this machine the bass speaker pin (NID 0x17) is by default routed to DAC 0x03, which has no volume amplifier capability, resulting in the right-side woofer being barely audible while only the tweeter plays. The Windows driver configures NID 0x17 to DAC 0x02, which is shared with the main speaker and carries proper amp control. Currently this machine has no PCI SSID quirk, so it falls through to the codec SSID fallback and matches the existing 0x17aa:0x3920 entry intended for the Yoga S990-16, applying only the TAS2781 I2C init without the DAC routing fix. Add a dedicated quirk for PCI SSID 17aa:3846 that forces NID 0x17 to DAC 0x02 via alc285_fixup_speaker2_to_dac1() and chains to ALC287_FIXUP_TXNW2781_I2C so the TAS2781 amplifier initialization is preserved.

ALSA: mtpav: shut down output timer before card teardown
snd_mtpav_output_timer() rearms chip->timer while holding
chip->spinlock and accesses the card-private mtpav state.
snd_mtpav_free() currently takes the same lock and calls
timer_delete() when the timer is active. This only removes a
pending timer; it does not wait for a callback that is already
running and does not prevent the callback from rearming the timer.
A callback running on another CPU can therefore continue after
snd_mtpav_free() releases the lock and access the card-private
state while the card is being torn down. It can also rearm the
timer after timer_delete() has returned.
Call timer_shutdown_sync() without holding chip->spinlock. This
waits for any running callback to finish and prevents further
rearming before the card-private mtpav state is released.

ALSA: ice1712: Fix the card leak at probe error with the auto-cleanup
snd_ice1712_probe() performs multiple initialization steps after
snd_card_new(), but directly returns on failures from later steps
without releasing the ALSA card, causing resource leaks when
probing fails.
Use snd_devm_card_new() together with scope-based cleanup
via __free(snd_card_unref), and clear the card pointer after
successful registration to keep it alive.

node devlink support and software node hogs
- shrink GPIO kunit initialization code
- coding style updates (remove commas from sentinels where applicable)
- with all users now converted treewide to using real firmware node links for
software node GPIO lookup: remove the deprecated label-matching mechanism
from from GPIO core
- drop redundant return value check of nonseekable_open() in gpiolib-cdev
- use IRQ trigger helpers where applicable
Driver updates:
- refactor error paths and logging in gpio-nomadik
- use more modern interfaces for getting resources in gpio-rockchip,
gpio-bt8xx and gpio-pca9570
- add missing MODULE_DEVICE_TABLE() to gpio-sifive and gpio-vf610
- drop unused FILONOFF macro from gpio-rcar
- extend build coverage of ioport GPIO drivers with COMPILE_TEST=y
- only enable the gpio-rtd driver by default with ARCH_REALTEK=y to avoid
bloating the build
- refactor coding style in several drivers
- use correct endianess translation in gpio-pcf85x
- add wake-up interrupt support to gpio-mvebu
- apply initial value in direction output setter in gpio-by-pinctrl
Misc:
- replace linux/gpio.h inclusions treewide with linux/gpio/legacy.h which now
exports all the deprecated APIs
- select GPIOLIB_LEGACY in Kconfig where required treewide
- use software nodes for gpio-keys in MFD drivers
Devicetree bindings:
- describe the realtek rtd1625 GPIO controller
- document new models for gpio-pca95xx and gpio-cadence
- document new property in gpio-rockchip
