ARM: socfpga: select the PL310 erratum 753970 workaround
ARCH_INTEL_SOCFPGA selects CACHE_L2X0 and several PL310 erratum
workarounds. The 753970 workaround is still conditioned on PL310, but that
Kconfig symbol no longer exists, so this one selection is always disabled.
Select PL310_ERRATA_753970 directly, consistently with the other PL310
workarounds required by the platform.
Fixes:

ARM updates for 7.3-rc1
- add module description for kprobes testing module
- remove references to CONFIG_CPU_ARM92x_CPU_IDLE options
- expand comment in ARM's __switch_to()
Also a number of fixes that missed 7.2:
- disable broken eBPF on RiscPC
- more BKPT fixes (guys, it's a *very* bad idea when everyone uses
the BKPT instruction for their own differing purposes.)
- another preempt-rt fix, this time for siglock / CPU timers
- fix another path where we try to send signals to processes
with interrupts disabled
- acquire mmap write lock for show_pte() with user faults

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.

soc: Arm platform updates for 7.3
The 32-bit Arm platforms are a bit more interesting this time: I refreshed
an earlier series to mark code as deprecated that does have the tendency
of getting in the way of cleanups and new features but has close to zero
users. Among these are:
- 22 of the remaining 28 legacy board files that predate the current
devicetree based descriptions, using old chips from Intel and Marvell.
The remaining six board files are for TI OMAP1 and Samsung s3c64xx
chips and all still have known users.
- support for Cortex-M3/M4/M7 and ARM1136r0 CPU cores and the 25
machines based on these. These all use devicetree but the CPU
support causes disproportional work. Most of them are just
reference boards, the notable exceptions being the Nokia N800/N810
tablet and the Buglabs BUG platform.
- be8, be32, oabi and iwmmxt userspace binaries, which were mostly
associated with the platforms now scheduled for removal and
are increasingly problematic to support with modern toolchains.
Nothing is actually removed at this point, to ensure that any remaining
users continue to have the 7.3-LTS for a while longer. Patches for
removal are currently being tested.
Other updates include a continued work to convert GPIO number based
interfaces to descriptors, a patch to restore little-endian mode
on the one Arm platform (ixp4xx) that only worked in big-endian mode
recently, and some minor cleanups and bugfixes.

soc: devicetree updates for 7.3
There are two new mystery SoCs with very little public information
about them so far, Qualcomm's Cortex-A78C based "Shikra" and
Altera's Cortex-A720 based Agilex72 SOCFPGA.
We have also gained support for a couple of SoCs from the
2023/2024 timeframe that have been in the making for a while:
- The Apple platform gains support for M3 Pro, Max and Ultra SoC,
following the basic M3 support from 7.2.
- Samsung Exynos 1580 is a high-end mobile phone SoC from 2024
- Canaan K230 is a RISC-V based 64-bit AI SoC, based on the
earlier K210 chip
- Sophgo SG2000 is a mixed Arm/RISC-V chip that was already
supported using the Arm core but is now also added for RISC-V
along with several other variants of the cv18xx series
In terms of newly added machines we have reference platforms
for all the chips above, plus
- only four 32-bit Arm boards: two older phones and two
older industrial/embedded boards; using Allwinner, Qualcomm and
Rockchip SoCs
- Three laptops und three phones using Qualcomm SoCs
- Ten 64-bit Rockchips based single-board computers, along with one
NAS box and a game console.
- Seven industrial/embedded boards and modules using NXP i.MX8/9 SoCs.
- A Lenovo desktop box based on NVIDIA Jetson Xavier NX
- A few more single-board computers based on Allwinnner A133,
Spacemit K1 and TI AM62.
As usual, there is a constant stream of minor cleanups and fixes
towards addressing the 'dt-check-style --mode strict' warnings,
and everyone is expected to address those warnings for new
submissions now.

VDSO updates:
- Consolidate the VDSO datastore further and provide support for
mlock_all() and prefaulting.
- Provide 32-bit legacy time related functionality only if
CONFIG_COMPAT_32BIT_TIME is enabled. The config switch exists, but
architecture code still exposes the legacy functionality even disabled.
Clean this up by adding the missing guards and validating at build time
that the VDSO is legacy free if disabled.
- Consolidate the VDSO related config options in core and drivers, which
removes some non-sensical dependencies and quite an amount of #ifdeffery.
- Clean up the PAGE_SIZE definition maze

Treewide timer related cleanups:
- Remove the leftover CLOCK_TICK_RATE which has been scheduled for
removal more than a decade ago along with some now empty asm/timex.h
files.
- Consolidate delay timer calibration
The construct of having a define in a header requires that
architectures provided asm/timex.h for no reason. Also the function
name for reading the delay timer is confusing at best.
Use a config switch to enable that functionality and rename the
function to delay_read_timer() to make the purpose clear.
This removes some more now empty asm/timex.h files as well.

Generic entry code updates:
- Make syscall user dispatching configurable
Not all architectures can makes use of syscall user dispatching. Allow
them to disable the feature completely.
- Consolidate stack randomization for the generic entry code and the
architectures using it.
Stack randomization on syscall entry was sprinkled throughout the
architecture specific low level entry code and in some cases at the
wrong points, e.g. before establishing state, which violates the
non-instrumentable constraints of that code.
Clean this up by integrating stack randomization into the generic entry
code helpers so that it is invoked at the earliest possible point right
after establishing state and converting all generic entry code using
architecture over.
- Clean up the syscall number handling in the generic entry code. It
works correctly for architectures which have a separate return value
storage in pt_regs, but fails to distinguish the case where user space
handed in -1 as syscall number from the case where the entry code
rejects it by returning -1 to the callers. Aside of that the return
value functionality of those interfaces is not really intuitive.
Fix this by separating the decision to reject a syscall (user dispatch,
ptrace, seccomp ...) from the potential modification of the syscall
number through these mechanisms.
This solves most of the problems for architectures which do not have a
separate return value storage in pt_regs except for the case where a
tracepoint has a BPF script or a probe attached which overwrite both
the syscall number and the return value. But that's a problem which
cannot be solved in the generic code, that only can be addressed by
separating the storage model in the affected architectures.

memblock: updates for 7.3-rc1
Non-urgent fixes:
* Fix calculation of node_spanned_pages when running with kernelcore=mirror
* Properly handle failure to allocate per_cpu_nodestats in
free_area_init_core_hotplug()
* Fix deferred initialization of the memory map for configurations where
node's RAM end is not aligned on PAGES_PER_SECTION
Cleanups:
* Remove redundant pageblock_align() call in free_unused_memmap()
* Remove unnecessary invalid range checks in users of memblock iterators.
Some users of for_each_mem_range() and for_each_mem_pfn_range() verify
that start < end for each range. This is redundant because memblock
iterators guarantee to never return an invalid range
* Stop overlapping zones with kernelcore=mirror and align behaviour of
kernelcore=mirror with other variants of kernelcore=/movablecore=
* Remove redundant updates of numa_nodes_parsed mask in the callers of
numa_add_memblk(), the latter always updates the mask anyway
* Remove unnecessary initialization of pgdat->per_cpu_nodestats to NULL,
the variable is reset to the actual value a few lines below

This allows userspace to shed their filesystem state completely. A process with its root or working directory in failfs must anchor every path lookup at an explicit file descriptor. Absolute paths, absolute symlinks and AT_FDCWD-relative lookups simply fail. Failfs is the counterpart to nullfs. nullfs says adds a permanently empty, immutable directory whose lookups fail with ENOENT but which can be opened, read, stat'd and mounted upon. Failfs on the other hand fails every operation. The root cannot be opened at all. A single instance is mounted during early boot via kern_mount(), which makes it logically distinct from every mount namespace. This is accompanied by a new fchroot() system call which makes chrooting via a file descriptor a first class concept. It's possible to chroot into failfs as an unprivileged user provided the task has no new privileges set" * tag 'vfs-7.3-rc1.failfs' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: Documentation: add failfs documentation selftests/filesystems: add failfs selftests arch: hookup fchroot() system call fs: support FD_FAILFS_ROOT in fchroot() fs: add fchroot() fs: support FD_FAILFS_ROOT in fchdir() fs: add failfs |

irqchip/gic-v3: make the unmasking of pseudo-NMIs explicit when handling IRQs
`gic_arch_enable_irqs()` is only used when handling IRQs (which could be pseudo-NMIs) and unmasking pseudo-NMIs. The chain of `gic_pmr_mask_irqs()` and `gic_arch_enable_irqs()` for it is slightly confusing without further explanation. Remove `gic_arch_enable_irqs()` and instead do the whole pseudo-NMI umasking in `gic_unmask_pnmis()`, making the operation explicit.

ARM: dts: helios4: add SATA regulator supplies
The ahci-mvebu driver and libahci_platform request three supplies
on SATA controller and port nodes:
- ahci-supply (controller power)
- phy-supply (PHY power)
- target-supply (disk power per port)
Without them the regulator core prints notices at boot, e.g.:
supply ahci not found, using dummy regulator
supply phy not found, using dummy regulator
supply target not found, using dummy regulator
The SATA controller and PHY inside the Armada 388 SoC are powered
by the 3.3V I/O rail; the four disk bays are powered by the 5V HDD
rail. Wire the existing fixed regulators accordingly.

ARM: dts: helios4: add vcc-supply to GPIO expander
The pca953x driver requests a 'vcc' supply, producing:
pca953x 0-0020: supply vcc not found, using dummy regulator
The PCA9655 (PCA9555-compatible) expander is powered by the same
always-on 3.3V rail as the other I2C devices on the bus. Add
vcc-supply = <®_3p3v> to silence the warning.

ARM: dts: helios4: add vcc-supply to EEPROM
The at24 driver requests a 'vcc' supply for the EEPROM, producing
'supply vcc not found, using dummy regulator' at boot when the
property is missing.
The EEPROM sits on the Helios 4 and is powered by the
same always-on 3.3V rail used by other on-board I2C devices.
Add vcc-supply = <®_3p3v> to silence the warning.

ARM: 9478/1: Remove references to removed CONFIG_CPU_ARM92x_CPU_IDLE options
Several assembly files in arch/arm/mm contain comments referring to CONFIG_CPU_ARM92x_CPU_IDLE options, which have not existed in the kernel since 2.4.21. Remove them. Discovered while searching for CONFIG_* symbols referenced in code but not defined in any Kconfig file.

ARM: 9485/1: mm: acquire mmap write lock around show_pte() for user faults
When CONFIG_DEBUG_USER=y, and cmdline "user_debug=31" is set,
a user fault may trigger show_pte() without any lock.
If another thread in the same process concurrently calls munmap(),
the page table pages may be freed while show_pte() is still traversing
them, causing a use-after-free in show_pte().
If CONFIG_ARM_LPAE=y, this may cause a kernel panic if the pages table
of PMD are freed when show_pte() is running.
Acquire mmap_write_lock() around show_pte() for user faults to fix the
contention.
For user faults, additionally restrict that show_pte() is called only
when the addr is a user-space address (addr < TASK_SIZE). This is because
the lock of tsk->mm only protects the virtual memory of user address space,
furthermore, dumping the page tables of a kernel-space address for user
faults is unnecessary and may have security implications.
Keep everything unchanged for kernel faults, because the kernel is
already in the "oops" state, acquiring a lock may risk a deadlock.

ARM: 9484/1: enable interrupts when unhandled user faults are triggered
PREEMPT_RT requires interrupts to be enabled when sending signals.
When do_DataAbort()/do_PrefetchAbort() triggers unhandled user faults,
that is `inf->fn()` return a non-zero value, and the interrupts are not
enabled within the hook function, force_sig_fault() will be called
with interrupts disabled.
This can be triggered by user programs executing the bkpt instruction,
with kernel config CONFIG_PERF_EVENTS=n.
Enable interrupts in do_DataAbort()/do_PrefetchAbort() when unhandled
user faults are triggered to fix the issue.

ARM: 9481/2: breakpoint: CFI breakpoints only on demand
This removes the stub hw_breakpoint_cfi_handler() from ARM, making
it not steal breakpoint type 0x03 (ARM_ENTRY_CFI_BREAKPOINT) unless
CFI is actively used in the kernel.
When not instrumenting with CFI, or when a breakpoint is issued in
userspace, we fall through to return 1 from hw_breakpoint_pending()
"unhandled fault" so userspace can make use of this breakpoint.
Tested with LKDTM and this command line:
echo CFI_FORWARD_PROTO > /sys/kernel/debug/provoke-crash/DIRECT
still works as expected.

ARM: 9477/1: Disable broken eBPF JIT on the Risc PC
The eBPF JIT unconditionally generates ldrh/strh instructions, which do
not function correctly on the Risc PC because its bus is unable to
signal half-word accesses. Work around this issue by disabling the eBPF
JIT when building for ARMv3 (the Risc PC is the only currently
supported machine whose kernel is built for ARMv3).
Comments from Ethan Nelson-Moore:
From LKML: https://lore.kernel.org/all/CAD++jL=0qYGoygUwGEXQL7C_ROnC7kfpRv8RA+H5tNWwYu+pQA@mail.gmail.com/
The commit message has been updated slightly relative to the version on LKML to clarify that the Risc PC is not actually ARMv3.

mm/rmap: rename vma_interval_tree_*() to mapping_rmap_tree_*()
The family of vma_interval_tree_() functions manipulate the address_space (which, of course, is generally referred to as 'mapping') reverse mapping, but are named the 'VMA' interval tree. VMAs may be mapped by an anon_vma, an address_space, or both. Therefore calling the mapping interval tree a 'VMA' interval tree is rather confusing. This is also inconsistent with the anon_vma_interval_tree_*() functions which explicitly reference the rmap object to which they pertain. Rename the vma_interval_tree_*() functions to mapping_rmap_tree_*() to correct this. We will rename the anon rmap functions similarly in a subsequent patch. No functional change intended.

mm/rmap: parameterise vma_interval_tree_*() by address_space
The file-backed mapping interval tree functions vma_interval_tree_*() accept a raw rb_root_cached pointer to determine the tree in which they are operating. However, in each case, this is always associated with an address_space data type. So simply pass a pointer to that instead to simplify the code, and more clearly differentiate between these operations and those concerning anonymous mappings. While we're here, make the generated interval tree functions static as they do not need to be used externally (any previously existing external users have now been removed). We also rename VMA parameters from 'node' to 'vma' as calling this a node is simply confusing, update the input index types to pgoff_t since they reference page offsets and rename the parameters to pgoff_start and pgoff_last.
