s390 updates for 7.3 merge window
- Add a cpuidle driver with polling and enabled wait states using the existing CPU idle infrastructure and idle governor to improve latency for frequent sleep/wakeup cycles. Remove the obsolete tick delay heuristic and generic arch_needs_cpu() hook. Add the corresponding driver entry to MAINTAINERS - Add kCFI support using the generic support provided by Clang - Enable Clang CONTEXT_ANALYSIS for various architecture code and for char, PCI, CIO and virtio drivers. Add required lock annotations, exclude unsupported mm helpers and remove conditional PCI locking - Fix secure storage access exception handling and reintroduce DCACHE_WORD_ACCESS previously removed as a workaround - Fix cpum_cf perf crashes when CPUs are brought online while per-task events are active. Allocate and remove per-CPU counter data from CPU hotplug callbacks - Fix a deadlock when an s390dbf debug area is unregistered while one of its debugfs files is being written to - Fix MVIY_PERCPU() with binutils older than 2.39, where an assembler macro silently omitted an instruction needed to repair interrupted operations after CPU migration - Remove/replace cond_resched() calls which are no-ops with the supported s390 preemption models - Fix AP queue depth and maximum message length decoding according to the architecture. Current hardware is not affected, but future hardware could report values which were handled incorrectly - Reflect the configured CPU state in cpu_enabled_mask so deconfigured CPUs are not presented as available for onlining - Restore the vDSO GNU_EH_FRAME program header which was lost when the build switched to direct linker invocation, and mark it read-only - Add SCLP action qualifiers used by Spyre for card initialization, recoverable error and telemetry reporting - Move KMSAN interrupt flag helpers out of line to fix -Wstatic-in-inline build warnings - Use level-specific page table entry accessors for hugetlb entries and ptep_get() when accessing crashed kernel memory in kdump - Make forced AP bus rescans killable so that a user process blocked behind an ongoing scan can still be terminated with SIGKILL - Rework pkey ioctl error paths to remove duplicated cleanup code and avoid freeing error pointers - Allow the protected guest SWIOTLB buffer to be allocated outside the first 2GB. Also enable dynamic SWIOTLB growth and the coherent atomic pool fallback to improve I/O behavior when the initial pool is exhausted - Add program check statistics and spinlock contention tracepoints.

kho: make boot time huge page allocation work nicely with KHO
Today allocation of gigantic pages in HugeTLB cannot work reliably with KHO:
* HugeTLB allocates gigantic pages using memblock and autoscaling of KHO
scratch accounts for these allocations. When gigantic pages occupy half
of the memory of more, KHO fails to allocate its scratch memory.
* After kexec handover, memblock allocations exclusively use KHO scratch
that is not supposed to contain preserved memory. This essentially blocks
preservation of HugeTLB with gigantic pages.
Extend early memory pools available for KHO kernel with areas that are
guaranteed not to contain preserved memory.

This contains a set of 142 SMB server updates focused on SMB2 command
sequencing, SMB3 request replay and encryption, Apple Time Machine
interoperability, protocol-compatibility fixes validated with smbtorture,
security hardening, SMB Direct transport support, connection reliability,
and other correctness improvements.
New features:
- Implement the SMB2 command sequence window.
Enforce the credit-based MessageId range for each connection, rejecting
out-of-window, duplicate, and wrapped sequence numbers. This prevents
invalid requests and same-channel replays from being processed.
- Add SMB3 request replay support.
SMB3 clients may resend requests with SMB2_FLAGS_REPLAY_OPERATION after
a channel disconnect when the original response was lost. Track the
required channel and open state to safely handle durable CREATE replays
and make oplock, lease, and lock replays idempotent, avoiding duplicate
state changes and improving multichannel reconnect reliability.
- Add opt-in Apple Time Machine support.
Implement the AAPL negotiation and related Finder, stream, COPYCHUNK,
sparse-file, CHANGE_NOTIFY, and RPC compatibility required for Time
Machine shares, allowing macOS backupd to use ksmbd for backups.
- Add per-share SMB3 encryption support.
Allow individual shares to require SMB3 encryption by advertising
SMB2_SHAREFLAG_ENCRYPT_DATA in TREE_CONNECT responses and rejecting
unencrypted tree connects and plaintext requests for protected shares.
- Add SMB Direct RDMA encryption support.
Extend SMB Direct to support SMB3 encrypted payloads over RDMA, with
transform negotiation and encryption/decryption for RDMA READ/WRITE.
Other changes:
- Parse and retain AppInstanceVersion contexts, enforce version ordering,
close older active handles for newer takeovers, and reject invalid or
unversioned opens according to the SMB2 semantics.
- Accept durable reconnect requests that omit VolatileFileId when the
persistent ID and reconnect context identify the handle, while
continuing to reject explicit volatile-ID mismatches.
- Fix SMB2/SMB3 protocol validation and security issues, including request
offsets, file and object IDs, IPC responses, output buffer sizes,
SMB3.1.1 binding validation, signing-required handling, durable handles,
ACLs, maximal access, and security information.
- Fix heap out-of-bounds accesses, use-after-free bugs, memory leaks,
invalid pointer dereferences, and sensitive-data lifetime issues in
authentication, Kerberos, preauthentication, sessions, connections,
and module teardown.
- Correct alternate-data-stream and named-stream handling, COPYCHUNK
behavior, sparse-file and compression attributes, allocated-range
queries, file trimming, duplicate extents, DOS attributes, snapshots,
normalized names, and partial information responses.
- Fix locking, lease, oplock, durable reconnect, async request, and
CHANGE_NOTIFY races, including deferred-lock rollback, parent directory
lease notifications, and connection teardown lifetime bugs.
- Fix SMB3 encryption handling for compressed requests, expired encrypted
sessions, interim responses, bound multichannel connections, and
decryption failures.
- Fix SMB3 multichannel session lookup and session state transitions so
changes are scoped to the correct bound connections and cannot revive
connections that are already shutting down.
- Fix DACL access checks so ACE walks are bounded by the declared DACL
size, preventing data beyond the DACL boundary from being interpreted
during access validation.
- Fix session accounting and lifetime issues, including session counter
updates during publication and removal, session leaks on registration
failure, and procfs creation diagnostics.
- Improve TCP connection reliability by enabling TCP keepalive for
accepted connections and preserving TCP timers for kernel sockets,
preventing silent peers from holding connections indefinitely.
- Fix smbdirect RDMA cleanup ordering for completion queues, QPs, child
sockets, and listener locking.
- Improve async response framing, multi-iovec signing, RPC pipe status
handling, and ksmbd procfs monitoring for server, share, connection,
session, and open-file state.
- Remove the obsolete DES crypto header and Kconfig dependency now that
NTLMv1 support has been removed.
- Update the ksmbd repository URL in MAINTAINERS and add an additional
KSMBD reviewer.

Total patches: 95 Reviews/patch: 0.63 Reviewed rate: 56% Summary of patch series in this merge: - "ocfs2/dlm: bound peer-controlled lengths in the o2dlm" (Bryam Vargas): Validate and bound all input lengths and count fields in the o2dlm migration and recovery receive handlers to prevent memory corruption and kernel panics from malformed cluster messages - "ocfs2: validate xattr entry bounds" (Cen Zhang): Validate OCFS2 extended attribute entry name and value bounds during metadata reads to prevent out-of-range memory accesses during retrieval or listing operations. - "taskstats: fix cgroupstats invalid fd handling and add selftests" (Yiyang Chen): Return -EBADF when cgroupstats receives an invalid file descriptor to prevent caller hangs and misleading success ACKs. Add a kselftest to validate valid cgroup v1 queries and verify proper error handling across different Netlink flag combinations. - "misc lib/raid/ improvements v2" (Christoph Hellwig): Improve benchmark-based algorithm selection for the XOR and RAID6 libraries, add KUnit benchmark tests, and cleanup minor implementation details. - "ocfs2: cluster: o2hb_region_pin() fixes" (Joseph Qi): Fix sleeping-in-atomic, lock order inversion and error-path cleanup bugs in o2hb_region_pin() by releasing o2hb_live_lock across sleeping configfs_depend_item() calls and using unlocked variants from callback context.

This contains a set of nine exfat fixes covering shared writable mappings,
entry error handling, allocation cleanup, FITRIM bounds, and locking:
- Fix valid_size extension over shared writable mappings by lazily
zeroing page-cache gaps and ensuring racing stores cannot be
overwritten or extend beyond valid_size.
- Clean up partially written directory entries on add-entry failure and
safely free new directory clusters.
- Free a newly allocated directory cluster when zeroing it fails.
- Write the destination entry before removing the source entry during
rename, preserving the source if the destination write fails.
- Keep FITRIM within the requested range, even when the free-space search
wraps around the allocation bitmap.
- Fix truncated FS_IOC_GETFSLABEL results by passing the destination
buffer size in bytes to the UTF-16-to-NLS conversion.
- Fix overflow in the cluster-to-dentry calculation, which could cause
readdir to stop early on large volumes.
- Replace the per-inode truncate_lock with inode_lock, using shared
locking in bmap to serialize against concurrent truncation.
- Update the exfat mailing list address in MAINTAINERS.

- Add 'function view' in perf c2c report TUI (switched by pressing 'TAB'
in the cacheline view) to organize samples around functions rather than
cachelines in 3-level hierarchy:
Level 1: Read-side function (sorted by estimated Cycles %)
Level 2: Contending writer functions (sorted by Store count)
Level 3: Shared cacheline addresses
Users can navigate the entries and fold/unfold using 'e' key. An example
output would look like below:
Shared Data Functions Table (19 entries, sorted on Cycles %)
Cycles Store
% count Function / Contending function / Cacheline
----------------------------------------------------------------------
+ 35.67% 876 + [k] cpupri_set
+ 24.31% 424 + [k] pull_rt_task

139 - [k] enqueue_pushable_task
70 0xff2d00a2071f9640
69 0xff2d0082809da000
python module support:
- Extend "perf" python module so that it can be fully functional. The goal
is to run scripts directly, not by 'perf script' command. This would give
better performance as well as more control to build standalone programs
with UI.
- Add LiveSession helper (perf_live.py) to enable live event collection
directly from Python using perf.evlist and perf.parse_events.
perf stat:
- Add --hide-zero-events option to suppress zero-count events.
- Reject conflicting --field-separator and --json-output options.
- Fix duplicate event output with --for-each-cgroup.
perf sched latency:
- Add -H/--histogram and --hist-mode (log|linear) options to show scheduler
wait latency histograms.
- Add --time option to filter analysis by time span in 'perf sched latency'.
ARM CoreSight:
- Synthesize callchains for instruction samples from CoreSight trace
using thread stack ('--itrace=g...').
- Support call indentation ('perf script -F +callindent') to display call
depth hierarchy on branch samples.
- Decode ETE (Embedded Trace Extension) exception packets.
Build system:
- Add 'make install-build-deps' target to install required packages.
- Parallelize JSON and metric pre-computation in jevents.py for faster builds.
Vendor event/metric updates:
- Add Intel Nova Lake events and update tables for existing models.
- Update AMD Zen 5 and Zen 6 core events.
- Update Arm64 Tegra410 metrics and PowerPC hcalls.
Internal changes and fixes:
- Harden trace-event and synthetic event parsing against corrupted data.
- Fix unwinding of multi-threaded processes in libdw unwinder.
- Fix memory leaks in various commands and python bindings.
- Speed up 'perf test' shell tests.

firewire updates for v7.3
This update includes error checks, a potential bug fix, and KUnit tests.
Sreeraj S Kurup addressed an error case when generating the contents of
the configuration ROM with parameters supplied by in-kernel
implementations such as unit drivers. Some error checks were added to
handle failures in this path.
Abdun Nihaal identified a potential memory leak when an invalid self-ID
sequence causes an error while building the internal node tree. KUnit
tests have been added to trigger this case. This memory leak has existed
since the first commit and has now been fixed.

Modules changes for 7.3-rc1
- Remove unnecessary module::args. Nowadays, no parameter-handling code points into the module::args buffer. The last user of module::args in xtensa/simdisk is updated and the data is then removed. - Add Rust support for boolean parameters. This will initially be used by the Rust null block driver. - Fix clearing the current charp parameter value when setting a new one fails due to an allocation failure. - Improve the debugging code for kmod (request_module()) duplicates. Fix a potential use-after-free when waiting on a duplicate request and make several general improvements to the code. - Fix the symbol size returned when looking up a data symbol through kallsyms. - The remaining changes are smaller fixes and cleanups. -----BEGIN PGP SIGNATURE----- iQFkBAABCABOFiEEIduBR9MnFA82q/jtumpXJwqY6poFAmqG/rIbFIAAAAAABAAO bWFudTIsMi41KzEuMTIsMiwyFBxwZXRyLnBhdmx1QHN1c2UuY29tAAoJELpqVycK mOqaur8H/i1kJq+zQfUB6/ijvX4yRGXezX0O30iLJ2N/imVsnMe6xP2eqqFIb2Be r5gnCc8P1WRJrDIe3uMsQBpoWIxEpCJ0F+S6JXiFEdht66taco8ivpP4hJWGHerj dCIf7RA3JOFave/7mN4UsrSXtl3HUyrMXplYuycE/5l/pYUY06qXmetgpA2aWywu jVpnCW9I7OO55Tf8tto2X4h6TbXP7ukCnojnadFz+N8JlG2hs45CQYSl1wEzKaFv okqPWCHTexcWySaEbqWWogbzvzIL6lr9C+nKMzYggMDYH7TxMwfscvo4pmTO/nOx +EO4PArCenf+7nsV2wKl2YLbnbzM1oA= =p/Yx -----END PGP SIGNATURE----- Merge tag 'modules-7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/modules/linux Pull module updates from Petr Pavlu: - Remove unnecessary module::args.

drm/xe: Don't hand out the flat CCS storage as usable VRAM
get_flat_ccs_offset() reads the base of the flat CCS storage from the
hardware, scales it by the number of enabled L3 nodes, and rounds the
result up to 128K. Everything below that offset is then handed to the
VRAM allocator as usable memory.
Rounding a limit that means "usable memory ends here" upwards publishes
whatever lies between the real base and the rounded one as free memory,
and that memory belongs to the compression hardware. The scaled value
has no reason to be 128K aligned, and on a Battlemage G21 with 16 GiB it
is not:
flat CCS base: raw 0x3fafff800, rounded 0x3fb000000
so the last 2 KiB of page 0x3fafff000 is CCS storage, in the allocator's
pool. Whatever is allocated there gets that tail overwritten by the
compression hardware, which needs no page-table entry, no buffer object
and no GPU submission to do it, and does it before userspace exists.
On this machine a Mesa VM's level-3 page table landed on that page on
every cold boot. It lost the entry covering the compositor's
batch-buffer heap, so the compositor's first submission faulted fetching
its batch and gdm restarted it forever: a black screen on an otherwise
working machine. Restarting gdm cleared it because the next VM's page
tables were allocated somewhere else.
Round down instead, to the page size the allocator works in. On this
machine that excludes exactly one page.
Reading the reserved page afterwards shows what had been writing it:
[369] 0xcccc000000000000
[371] 0xcc77000000000000
[373] 0xcccc000000000000
[375] 0xcc77000000000000
compression metadata, two bytes per sixteen, sitting where the driver
used to hand out memory.
The assertion that should have caught this compares the offset against
GSMBASE - ccs_size for equality. That value is 128K aligned, so it
agrees with the rounded-up offset precisely when the base is not
aligned - the check cannot fail in the case it exists to catch, and is
compiled out unless CONFIG_DRM_XE_DEBUG is set. Replace it with one
that can fail: CCS storage must not run into GSM.
[ And this was a debug session from hell, enormously helped by an AI
doing much of the grunt-work.
I'd like to call it my tireless helper, but the AI several times
stated flat out that this was impossible and unsolvable and that we
should just write a report about it.
I suspect those things have been trained by people who may not be
quite as stubborn as I am.
But while the AI was ready to give up several times, it did keep
adding debug code and analyzing it faithfully when I pushed. So credit
where credit is due and I let the AI write the commit message above.
This is basically a one-liner fixing a bogus "round_up()" to a
"round_down()", but there were 24 patches adding more and more debug
information to this, and 18 kernel boot to finally narrow it down to
this. - Linus ]

KEYS: trusted: Fix TPM teardown ordering
trusted_tpm_exit() drops the TPM chip reference and frees the digest
array before unregistering the trusted key type. key_type_lookup()
holds key_types_sem for reading until the key operation finishes, while
unregister_key_type() takes it for writing. It therefore provides the
synchronization point that must precede backend teardown.
The current order permits this interleaving:
CPU 0 CPU 1
trusted_tpm_exit() key_type_lookup("trusted")
put_device(&chip->dev) trusted_tpm_seal()
kfree(digests) pcrlock()
unregister_key_type() tpm_pcr_extend(..., digests)
CPU 1 can consequently dereference the freed digest array. The chip can
also be released before callbacks stop using it.
KASAN reported:
BUG: KASAN: slab-use-after-free in tpm_pcr_extend+0x1f0/0x200

Move unregister_key_type() before releasing either resource. This stops
new lookups and waits for in-flight key operations to finish before the
backend state is destroyed.

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
dependencies by introducing hugetlb_alloc_folio(), enabling subsystems
like guest_memfd to allocate HugeTLB folios without standard VMA
reservations or pseudo-VMAs.
- The 3 patch series "mm/damon: provide pseudo moving sum probe_hits"
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.

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.

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.

VFIO updates for v7.3-rc1
- Add nv_falcon vfio selftest driver. The Falcon is a general-purpose
microcontroller embedded within NVIDIA GPUs, presenting a relatively
simple DMA programming interface. This adds another selftest target
for vfio-pci with real DMA transfers. (Rubin Du, Alex Williamson)
- Add allocation assertion helpers to vfio selftests and use them to
avoid variable length arrays and the compiler errors they generate.
(Alex Mastro)
- Fix use-after-free hazard where an init path error in MSI support
leaves a stray pointer that can later be reused or double-freed.
(Xiang Mei)
- Fix previous refactor of PCI BAR mappings to honor non_mappable_bars
flag, which otherwise generates a warning when trying to pci_iomap()
a 256TiB BAR on ISM devices on s390. (Farhan Ali)
- Add igb vfio selftest driver. Like nv_falcon, this provides another
target for DMA testing with vfio selftests, but importantly this
driver supports both physical 82576 NICs and the emulation model in
QEMU. This therefore enables a vfio selftest vector with no physical
hardware requirements. (Josh Hilke, Alex Williamson)
- Mark selftest fixture objects __maybe_unused to accommodate builds
with clang -Wunused-but-set-global. (David Matlack)
- Add error recovery for vfio-pci devices on s390x. This expands
devices which expose the existing error eventfd and introduces a
device feature for reporting firmware defined error state
information to the user, allowing recovery through hypervisor
channels. (Farhan Ali)

Probes updates for v7.3:
- probes: Advanced BTF typecasting and variable fetch enhancements
. Typecast support across probe events: Extended BTF typecasting syntax
(e.g., (STRUCT)PARAM->MEMBER) to kprobes, uprobes, and fprobes on
function entry and return.
. Nested typecasts: Added support for chaining and nesting typecasts up
to 3 levels, including casting registers and stack variables.
. Field specifier option: Added (STRUCT,FIELD) syntax to emulate
container_of(), allowing retrieval of parent structures from member
pointers.
. $current variable support: Introduced $current special variable to
access the running task_struct via BTF dereferencing.
. Per-CPU variable access: Added this_cpu_read() and this_cpu_ptr()
fetcharg methods to trace CPU-local data safely.
. Fetcharg bytecode dumper: Added CONFIG_PROBE_EVENTS_DUMP_FETCHARG to
dump the compiled fetcharg bytecode instructions as comments in
dynamic_events.
. Extended symbol name handling: Removed the MAX_COMMON_HEAD_LEN limit
and extended MAX_ARGSTR_LEN to 256 bytes, enabling probing of long
symbols, mangled Rust symbols and complex BTF expressions.
. eprobe variable syntax: Allowed eprobes to reference event fields
directly without requiring a '$' prefix.
. Cleanup unused parameters, redundant codes, duplicate macros and
pointer arithmetic.
. Use a ternary operator for simplifying fetch_type_from_btf_type().
- bootconfig / boottime-trace: Expanded dynamic probe support

unaligned memory access penalties on RISC architectures.
. kprobe & fprobe: Removed redundant memset() calls in perf event probe
handlers.
. kprobes: Replaced legacy __ASSEMBLY__ with __ASSEMBLER__ in header
files.
- selftests & refactoring:

fbdev: atafb: Add support for SuperVidel's SuperBlitter
The SuperVidel graphics FPGA includes a hardware blitter (bit block transfer engine) operating within the SuperVidel DDR2 video RAM. Two versions of this blitter exist. Later versions (>= 9) of the SuperVidel firmware support an asynchronous command FIFO, older versions must be polled for command completion. Add hardware-accelerated copyarea, fillrect and imageblit fb operations (falling back to the non-accelerated versions for anything that exceeds blitter capabilities).

fbdev: atafb: Give atafb proper parent
The atafb fb device registers no parent, causing a missing symlink (/sys/class/graphics/fb0/device). Xorg fbdevhw driver looks for that symlink when scanning for devices, so add a parent node for atafb. The proper way to do that is use of framebuffer_alloc(), which requries refactoring atafb to move from static fb_info to allocation of fb_info by framebuffer_alloc(). About the only location where a fb_info pointer cannot be passed is monspec setup in atafb_setup(). Store static monspecs there and copy into place after framebuffer_alloc(). Pass fb_info everywhere it's needed (detect, decode_var and do_fb_set_var functions), and remove the static fb_info struct.

A set of unit testing support to catch regressions for the CXL core type2 exported functions has also been added. The actual CXL type 2 driver support for the AMD Solarflare NIC driver has been picked up by net-dev. A set of preparatory patches has been picked up from the CXL port error handling series in order to reduce the number of patches in that series for review. The rest of that series is getting close to be merged but was not ready for the 7.3 merge window. There are also a number of misc patches and a large number of bug fixes against pre-existing issues flagged by sashiko reviews as contributors post new patches on the mailing list. We will continue to work through the sashiko raised issues as they show up." * tag 'cxl-for-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: (35 commits) cxl/Documentation: Spell out globbed sysfs attribute names cxl: Rename find_cxl_port() to find_cxl_port_by_dport() cxl: Tighten CPER kfifo registration API and symbol visibility acpi/apei/ghes: Use raw_spinlock_t for CXL CPER work locks cxl/ras: Fix cxl_rch_get_aer_severity() wrong severity register cxl/ras: Fix cxl_rch_get_aer_info() out-of-bounds AER register read cxl/test: Assign one mock memdev a full-width serial number cxl/core: Format the memdev serial number as unsigned in TP_printk cxl/pmem: Format the nvdimm serial number as unsigned decimal cxl: Use %pe to print error pointers cxl/region: Use __free(put_device) in find_pos_and_ways() cxl/region: Fix use-after-free in find_pos_and_ways() error path cxl: Deny Features commands on the RAW mailbox path cxl/features: Clamp Get Feature output size to the remaining buffer cxl/features: Reject Set Features output buffer smaller than the header cxl/features: Reject Get Feature count larger than the output buffer cxl/port: Restart port enumeration when a sibling adds the dport first cxl/features: Serialize multi-part Get/Set Feature transfers cxl/pci: Honor -EPROBE_DEFER from component register setup cxl/mbox: Break poison list loop on an empty payload ... |

RISC-V updates for v7.3
- Add initial definitions and discovery for the Smcsrind, Sscsrind, Smcntrpmf, Ssccfg, Smcdeleg, Zicclsm, Ziccamoa, Ziccif, Ziccrse, Za64rs, and Ssqosid RISC-V ISA extensions - Improve the RISC-V update_mmu_cache_range() implementation by using flush-by-ASID, enabling performance improvements on microarchitectures that support related optimizations; and by taking advantage of the Svinval RISC-V ISA extension on microarchitectures that support it - Shrink CFI shadow stack allocation further (to 512MB) to save virtual address space (and physical memory on systems with strict overcommit policies) - Add initial CPU context switch support for QoS tagging (Ssqosid) - Change our vector misaligned access speed test code to be synchronous, avoiding a bunch of bugs related to unnecessary asynchronicity - Enable ARCH_HAS_ACPI_TABLE_UPGRADE for RISC-V to help with ACPI table debugging (similar to ARM64 and x86) - Extract vDSO section offsets at build time, rather than run time, to avoid the boot time overhead - Use assembler directives to control the use of instructions from the RISC-V ISA extensions Zacas and Zabha, rather than compiler -march flags that could affect the whole kernel (similar to ARM64) - Add a kselftest for kprobes support for the c.jal instruction on RISC-V - When UEFI runtime services are available, use them to restart and power off - Fix ARCH_HAS_ACPI_TABLE_UPGRADE for RISC-V by adding a missing include file to the ACPI code - Move contiguous DMA memory reservation later in the boot, to ensure that the correct global and per-node pools are allocated when CONFIG_CMA_SIZE_PERNUMA is enabled - Disallow probes on breakpoint handlers to avoid recursing indefinitely into do_trap_break() - Patch the compat vDSO during runtime alternatives processing, not only the standard vDSO - Remove some leftover XIP support elements missed by commit |

fbdev: omapfb: panel-dsi-cm: initialize lock before registering display
dsicm_probe() registers the display before initializing ddata->lock.
Once omapdss_register_display() publishes the display, another consumer
can reach a dsicm callback that takes this mutex while it is still
uninitialized.
Initialize the mutex before registering the display so the published
callbacks always see a valid lock.
Fixes:

fbdev: viafb: refactor strcpy and viafb_name
Eliminate the single-use file-scope variable `viafb_name` and pass the "Via" string literal directly to strcpy(). Since "Via" is a literal constant, the compiler safely executes compile-time bounds checking during fortify verification. This satisfies the security initiative requirements while minimizing code complexity. Signed-off-by: Ajith P V <ajithpv.linux@gmail.com> Signed-off-by: Helge Deller <deller@gmx.de> |

fbdev: platinumfb: add error checking for ioremap calls
The ioremap() and ioremap_wt() calls in platinumfb_probe() were not checked for failure. If any of these mappings fail, the driver would dereference NULL pointers, leading to a kernel panic. Add proper error checking and use goto-based cleanup to avoid code duplication across the error paths. Signed-off-by: BingKun Yue <yuebingkun@kylinos.cn> Signed-off-by: Helge Deller <deller@gmx.de> |
