beace86e61 Summary of significant series in this pull request:
- The 4 patch series "mm: ksm: prevent KSM from breaking merging of new
   VMAs" from Lorenzo Stoakes addresses an issue with KSM's
   PR_SET_MEMORY_MERGE mode: newly mapped VMAs were not eligible for
   merging with existing adjacent VMAs.
 
 - The 4 patch series "mm/damon: introduce DAMON_STAT for simple and
   practical access monitoring" from SeongJae Park adds a new kernel module
   which simplifies the setup and usage of DAMON in production
   environments.
 
 - The 6 patch series "stop passing a writeback_control to swap/shmem
   writeout" from Christoph Hellwig is a cleanup to the writeback code
   which removes a couple of pointers from struct writeback_control.
 
 - The 7 patch series "drivers/base/node.c: optimization and cleanups"
   from Donet Tom contains largely uncorrelated cleanups to the NUMA node
   setup and management code.
 
 - The 4 patch series "mm: userfaultfd: assorted fixes and cleanups" from
   Tal Zussman does some maintenance work on the userfaultfd code.
 
 - The 5 patch series "Readahead tweaks for larger folios" from Ryan
   Roberts implements some tuneups for pagecache readahead when it is
   reading into order>0 folios.
 
 - The 4 patch series "selftests/mm: Tweaks to the cow test" from Mark
   Brown provides some cleanups and consistency improvements to the
   selftests code.
 
 - The 4 patch series "Optimize mremap() for large folios" from Dev Jain
   does that.  A 37% reduction in execution time was measured in a
   memset+mremap+munmap microbenchmark.
 
 - The 5 patch series "Remove zero_user()" from Matthew Wilcox expunges
   zero_user() in favor of the more modern memzero_page().
 
 - The 3 patch series "mm/huge_memory: vmf_insert_folio_*() and
   vmf_insert_pfn_pud() fixes" from David Hildenbrand addresses some warts
   which David noticed in the huge page code.  These were not known to be
   causing any issues at this time.
 
 - The 3 patch series "mm/damon: use alloc_migrate_target() for
   DAMOS_MIGRATE_{HOT,COLD" from SeongJae Park provides some cleanup and
   consolidation work in DAMON.
 
 - The 3 patch series "use vm_flags_t consistently" from Lorenzo Stoakes
   uses vm_flags_t in places where we were inappropriately using other
   types.
 
 - The 3 patch series "mm/memfd: Reserve hugetlb folios before
   allocation" from Vivek Kasireddy increases the reliability of large page
   allocation in the memfd code.
 
 - The 14 patch series "mm: Remove pXX_devmap page table bit and pfn_t
   type" from Alistair Popple removes several now-unneeded PFN_* flags.
 
 - The 5 patch series "mm/damon: decouple sysfs from core" from SeongJae
   Park implememnts some cleanup and maintainability work in the DAMON
   sysfs layer.
 
 - The 5 patch series "madvise cleanup" from Lorenzo Stoakes does quite a
   lot of cleanup/maintenance work in the madvise() code.
 
 - The 4 patch series "madvise anon_name cleanups" from Vlastimil Babka
   provides additional cleanups on top or Lorenzo's effort.
 
 - The 11 patch series "Implement numa node notifier" from Oscar Salvador
   creates a standalone notifier for NUMA node memory state changes.
   Previously these were lumped under the more general memory on/offline
   notifier.
 
 - The 6 patch series "Make MIGRATE_ISOLATE a standalone bit" from Zi Yan
   cleans up the pageblock isolation code and fixes a potential issue which
   doesn't seem to cause any problems in practice.
 
 - The 5 patch series "selftests/damon: add python and drgn based DAMON
   sysfs functionality tests" from SeongJae Park adds additional drgn- and
   python-based DAMON selftests which are more comprehensive than the
   existing selftest suite.
 
 - The 5 patch series "Misc rework on hugetlb faulting path" from Oscar
   Salvador fixes a rather obscure deadlock in the hugetlb fault code and
   follows that fix with a series of cleanups.
 
 - The 3 patch series "cma: factor out allocation logic from
   __cma_declare_contiguous_nid" from Mike Rapoport rationalizes and cleans
   up the highmem-specific code in the CMA allocator.
 
 - The 28 patch series "mm/migration: rework movable_ops page migration
   (part 1)" from David Hildenbrand provides cleanups and
   future-preparedness to the migration code.
 
 - The 2 patch series "mm/damon: add trace events for auto-tuned
   monitoring intervals and DAMOS quota" from SeongJae Park adds some
   tracepoints to some DAMON auto-tuning code.
 
 - The 6 patch series "mm/damon: fix misc bugs in DAMON modules" from
   SeongJae Park does that.
 
 - The 6 patch series "mm/damon: misc cleanups" from SeongJae Park also
   does what it claims.
 
 - The 4 patch series "mm: folio_pte_batch() improvements" from David
   Hildenbrand cleans up the large folio PTE batching code.
 
 - The 13 patch series "mm/damon/vaddr: Allow interleaving in
   migrate_{hot,cold} actions" from SeongJae Park facilitates dynamic
   alteration of DAMON's inter-node allocation policy.
 
 - The 3 patch series "Remove unmap_and_put_page()" from Vishal Moola
   provides a couple of page->folio conversions.
 
 - The 4 patch series "mm: per-node proactive reclaim" from Davidlohr
   Bueso implements a per-node control of proactive reclaim - beyond the
   current memcg-based implementation.
 
 - The 14 patch series "mm/damon: remove damon_callback" from SeongJae
   Park replaces the damon_callback interface with a more general and
   powerful damon_call()+damos_walk() interface.
 
 - The 10 patch series "mm/mremap: permit mremap() move of multiple VMAs"
   from Lorenzo Stoakes implements a number of mremap cleanups (of course)
   in preparation for adding new mremap() functionality: newly permit the
   remapping of multiple VMAs when the user is specifying MREMAP_FIXED.  It
   still excludes some specialized situations where this cannot be
   performed reliably.
 
 - The 3 patch series "drop hugetlb_free_pgd_range()" from Anthony Yznaga
   switches some sparc hugetlb code over to the generic version and removes
   the thus-unneeded hugetlb_free_pgd_range().
 
 - The 4 patch series "mm/damon/sysfs: support periodic and automated
   stats update" from SeongJae Park augments the present
   userspace-requested update of DAMON sysfs monitoring files.  Automatic
   update is now provided, along with a tunable to control the update
   interval.
 
 - The 4 patch series "Some randome fixes and cleanups to swapfile" from
   Kemeng Shi does what is claims.
 
 - The 4 patch series "mm: introduce snapshot_page" from Luiz Capitulino
   and David Hildenbrand provides (and uses) a means by which debug-style
   functions can grab a copy of a pageframe and inspect it locklessly
   without tripping over the races inherent in operating on the live
   pageframe directly.
 
 - The 6 patch series "use per-vma locks for /proc/pid/maps reads" from
   Suren Baghdasaryan addresses the large contention issues which can be
   triggered by reads from that procfs file.  Latencies are reduced by more
   than half in some situations.  The series also introduces several new
   selftests for the /proc/pid/maps interface.
 
 - The 6 patch series "__folio_split() clean up" from Zi Yan cleans up
   __folio_split()!
 
 - The 7 patch series "Optimize mprotect() for large folios" from Dev
   Jain provides some quite large (>3x) speedups to mprotect() when dealing
   with large folios.
 
 - The 2 patch series "selftests/mm: reuse FORCE_READ to replace "asm
   volatile("" : "+r" (XXX));" and some cleanup" from wang lian does some
   cleanup work in the selftests code.
 
 - The 3 patch series "tools/testing: expand mremap testing" from Lorenzo
   Stoakes extends the mremap() selftest in several ways, including adding
   more checking of Lorenzo's recently added "permit mremap() move of
   multiple VMAs" feature.
 
 - The 22 patch series "selftests/damon/sysfs.py: test all parameters"
   from SeongJae Park extends the DAMON sysfs interface selftest so that it
   tests all possible user-requested parameters.  Rather than the present
   minimal subset.

b1cce98493 It has been a relatively busy cycle for docs, especially the build system:
- The Perl kernel-doc script was added to 2.3.52pre1 just after the turn of
   the millennium.  Over the following 25 years, it accumulated a vast
   amount of cruft, all in a language few people want to deal with anymore.
   Mauro's Python replacement in 6.16 faithfully reproduced all of the cruft
   in the hope of avoiding regressions.  Now that we have a more reasonable
   code base, though, we can work on cleaning it up; many of the changes
   this time around are toward that end.
 
 - A reorganization of the ext4 docs into the usual TOC format.
 
 - Various Chinese translations and updates.
 
 - A new script from Mauro to help with docs-build testing.
 
 - A new document for linked lists
 
 - A sweep through MAINTAINERS fixing broken GitHub git:// repository links.
 
 ...and lots of fixes and updates.

57fbad15c2 stackleak: Rename STACKLEAK to KSTACK_ERASE
In preparation for adding Clang sanitizer coverage stack depth tracking
that can support stack depth callbacks:

- Add the new top-level CONFIG_KSTACK_ERASE option which will be
  implemented either with the stackleak GCC plugin, or with the Clang
  stack depth callback support.
- Rename CONFIG_GCC_PLUGIN_STACKLEAK as needed to CONFIG_KSTACK_ERASE,
  but keep it for anything specific to the GCC plugin itself.
- Rename all exposed "STACKLEAK" names and files to "KSTACK_ERASE" (named
  for what it does rather than what it protects against), but leave as
  many of the internals alone as possible to avoid even more churn.

While here, also split "prev_lowest_stack" into CONFIG_KSTACK_ERASE_METRICS,
since that's the only place it is referenced from.

dee264c16a require gcc-8 and binutils-2.30
x86 already uses gcc-8 as the minimum version, this changes all other
 architectures to the same version. gcc-8 is used is Debian 10 and Red
 Hat Enterprise Linux 8, both of which are still supported, and binutils
 2.30 is the oldest corresponding version on those. Ubuntu Pro 18.04 and
 SUSE Linux Enterprise Server 15 both use gcc-7 as the system compiler
 but additionally include toolchains that remain supported.
 
 With the new minimum toolchain versions, a number of workarounds for older
 versions can be dropped, in particular on x86_64 and arm64.  Importantly,
 the updated compiler version allows removing two of the five remaining
 gcc plugins, as support for sancov and structeak features is already
 included in modern compiler versions.
 
 I tried collecting the known changes that are possible based on the
 new toolchain version, but expect that more cleanups will be possible.
 Since this touches multiple architectures, I merged the patches through
 the asm-generic tree.

Linus Torvalds
1b98f357da Networking changes for 6.16.
Core
 ----
 
  - Implement the Device Memory TCP transmit path, allowing zero-copy
    data transmission on top of TCP from e.g. GPU memory to the wire.
 
  - Move all the IPv6 routing tables management outside the RTNL scope,
    under its own lock and RCU. The route control path is now 3x times
    faster.
 
  - Convert queue related netlink ops to instance lock, reducing
    again the scope of the RTNL lock. This improves the control plane
    scalability.
 
  - Refactor the software crc32c implementation, removing unneeded
    abstraction layers and improving significantly the related
    micro-benchmarks.
 
  - Optimize the GRO engine for UDP-tunneled traffic, for a 10%
    performance improvement in related stream tests.
 
  - Cover more per-CPU storage with local nested BH locking; this is a
    prep work to remove the current per-CPU lock in local_bh_disable()
    on PREMPT_RT.
 
  - Introduce and use nlmsg_payload helper, combining buffer bounds
    verification with accessing payload carried by netlink messages.
 
 Netfilter
 ---------
 
  - Rewrite the procfs conntrack table implementation, improving
    considerably the dump performance. A lot of user-space tools
    still use this interface.
 
  - Implement support for wildcard netdevice in netdev basechain
    and flowtables.
 
  - Integrate conntrack information into nft trace infrastructure.
 
  - Export set count and backend name to userspace, for better
    introspection.
 
 BPF
 ---
 
  - BPF qdisc support: BPF-qdisc can be implemented with BPF struct_ops
    programs and can be controlled in similar way to traditional qdiscs
    using the "tc qdisc" command.
 
  - Refactor the UDP socket iterator, addressing long standing issues
    WRT duplicate hits or missed sockets.
 
 Protocols
 ---------
 
  - Improve TCP receive buffer auto-tuning and increase the default
    upper bound for the receive buffer; overall this improves the single
    flow maximum thoughput on 200Gbs link by over 60%.
 
  - Add AFS GSSAPI security class to AF_RXRPC; it provides transport
    security for connections to the AFS fileserver and VL server.
 
  - Improve TCP multipath routing, so that the sources address always
    matches the nexthop device.
 
  - Introduce SO_PASSRIGHTS for AF_UNIX, to allow disabling SCM_RIGHTS,
    and thus preventing DoS caused by passing around problematic FDs.
 
  - Retire DCCP socket. DCCP only receives updates for bugs, and major
    distros disable it by default. Its removal allows for better
    organisation of TCP fields to reduce the number of cache lines hit
    in the fast path.
 
  - Extend TCP drop-reason support to cover PAWS checks.
 
 Driver API
 ----------
 
  - Reorganize PTP ioctl flag support to require an explicit opt-in for
    the drivers, avoiding the problem of drivers not rejecting new
    unsupported flags.
 
  - Converted several device drivers to timestamping APIs.
 
  - Introduce per-PHY ethtool dump helpers, improving the support for
    dump operations targeting PHYs.
 
 Tests and tooling
 -----------------
 
  - Add support for classic netlink in user space C codegen, so that
    ynl-c can now read, create and modify links, routes addresses and
    qdisc layer configuration.
 
  - Add ynl sub-types for binary attributes, allowing ynl-c to output
    known struct instead of raw binary data, clarifying the classic
    netlink output.
 
  - Extend MPTCP selftests to improve the code-coverage.
 
  - Add tests for XDP tail adjustment in AF_XDP.
 
 New hardware / drivers
 ----------------------
 
  - OpenVPN virtual driver: offload OpenVPN data channels processing
    to the kernel-space, increasing the data transfer throughput WRT
    the user-space implementation.
 
  - Renesas glue driver for the gigabit ethernet RZ/V2H(P) SoC.
 
  - Broadcom asp-v3.0 ethernet driver.
 
  - AMD Renoir ethernet device.
 
  - ReakTek MT9888 2.5G ethernet PHY driver.
 
  - Aeonsemi 10G C45 PHYs driver.

aacc73ceeb gpio updates for v6.16-rc1
GPIO core:
 - use more lock guards where applicable
 - refactor GPIO ACPI code and shrink it in the process by 8%
 - move GPIO ACPI quirks into a separate file
 - remove unneeded #ifdef
 - convert GPIO devres helpers to using devm_add_action() where applicable
   which shrinks and simplifies the code
 - refactor GPIO descriptor validation in GPIO consumer interfaces
 - don't allow setting values on input lines in the GPIO core which will
   take off the burden from GPIO drivers of checking this down the line
 - provide gpiod_is_equal() as a way of safely comparing two GPIO
   descriptors (the only current user is in regulator core)
 
 New drivers:
 - add the GPIO module for the max77759 multifunction device
 - add the GPIO driver for the VeriSilicon BLZP1600 GPIO controller
 - add the GPIO driver for the Spacemit K1 SoC
 
 Driver improvements:
 - convert more drivers to using the new GPIO line value setter callbacks
 - convert more drivers to making the irq_chip immutable as is recommended
   by the interrupt subsystem
 - extend build testing coverage by enabling more modules to be built with
   COMPILE_TEST=y
 - extend the gpio-aggregator module with a configfs interface that makes
   the setup easier for user-space than the existing driver-level sysfs
   attributes and also adds more advanced configuration features (such as
   referring to aggregated lines by their original names or modifying
   their names as exposed by the aggregated chip)
 - add a missing mutex_destroy() in gpio-imx-scu
 - add an OF polarity quirk for s5m8767
 - allow building gpio-vf610 as a loadable module
 - make gpio-mxc not hardcode its GPIO base number with GPIO SYSFS
   interface disabled (another small step towards getting rid of the global
   GPIO numberspace)
 - add support for level-triggered interrupts to gpio-pca953x
 - don't double-check the ngpios property in gpio-ds4520 as GPIO core
   already does it
 - don't double-check the number of GPIOs in gpio-imx-scu as GPIO core

 - remove unused callbacks from gpio-max3191x
 
 DT bindings:
 - add device-tree bindings for max77759, spacemit,k1 and blzp1600 (new
   drivers added this cycle)
 - document more properties for gpio-vf610 and gpio-tegra186
 - document a new pca95xx variant
 - fix style of examples in several GPIO DT-binding documents

Pull gpio updates from Bartosz Golaszewski:
 "We have three new drivers, some refactoring in the GPIO core, lots of
  various changes across many drivers, new configfs interface for the
  virtual gpio-aggregator module and DT-bindings updates.

  The treewide conversion of GPIO drivers to using the new value setter
  callbacks is ongoing with another round of GPIO drivers updated. You
  will also see these commits coming in from other subsystems as with
  the relevant changes merged into mainline last cycle, I've started

3e443d1673 A moderately busy cycle for documentation this time around:
- The most significant change is the replacement of the old kernel-doc
   script (a monstrous collection of Perl regexes that predates the Git era)
   with a Python reimplementation.  That, too, is a horrifying collection of
   regexes, but in a much cleaner and more maintainable structure that
   integrates far better with the Sphinx build system.
 
   This change has been in linux-next for the full 6.15 cycle; the small
   number of problems that turned up have been addressed, seemingly to
   everybody's satisfaction.  The Perl kernel-doc script remains in tree (as
   scripts/kernel-doc.pl) and can be used with a command-line option if need
   be.  Unless some reason to keep it around materializes, it will probably
   go away in 6.17.
 
   Credit goes to Mauro Carvalho Chehab for doing all this work.

All irq_domain_add_*() functions are going away. PowerPC is the only

complement.

Therefore, to align with the rest of the kernel, rename

fwnode_handle instead of a device_node.

592ebd77e6 vsprintf: remove redundant and unused %pCn format specifier
%pC and %pCn print the same string, and commit 900cca2944 ("lib/vsprintf:
add %pC{,n,r} format specifiers for clocks") introducing them does not
clarify any intended difference. It can be assumed %pC is a default for
%pCn as some other specifiers do, but not all are consistent with this
policy. Moreover there is now no other suffix other than 'n', which makes a
default not really useful.

All users in the kernel were using %pC except for one which has been
converted. So now remove %pCn and all the unnecessary extra code and
documentation.

09e1d93a42 scripts/gdb: update documentation for lx_per_cpu
Commit db08c53fdd ("scripts/gdb: fix parameter handling in
$lx_per_cpu") changed the parameter handling of lx_per_cpu to use GdbValue
instead of parsing the variable name.  Update the documentation to reflect
the new lx_per_cpu usage.  Update the hrtimer_bases example to use rb_tree
instead of the timerqueue_head.next pointer removed in commit
511885d706 ("lib/timerqueue: Rely on rbtree semantics for next
timer").

118c40b7b5 kbuild: require gcc-8 and binutils-2.30
Commit a3e8fe814a ("x86/build: Raise the minimum GCC version to 8.1")
raised the minimum compiler version as enforced by Kbuild to gcc-8.1
and clang-15 for x86.

This is actually the same gcc version that has been discussed as the
minimum for all architectures several times in the past, with little
objection. A previous concern was the kernel for SLE15-SP7 needing to
be built with gcc-7. As this ended up still using linux-6.4 and there
is no plan for an SP8, this is no longer a problem.

Change it for all architectures and adjust the documentation accordingly.
A few version checks can be removed in the process.  The binutils
version 2.30 is the lowest version used in combination with gcc-8 on
common distros, so use that as the corresponding minimum.

2a63dd0edf net: Retire DCCP socket.
DCCP was orphaned in 2021 by commit 054c4610bd ("MAINTAINERS: dccp:
move Gerrit Renker to CREDITS"), which noted that the last maintainer
had been inactive for five years.

In recent years, it has become a playground for syzbot, and most changes
to DCCP have been odd bug fixes triggered by syzbot.  Apart from that,
the only changes have been driven by treewide or networking API updates
or adjustments related to TCP.

Thus, in 2023, we announced we would remove DCCP in 2025 via commit
b144fcaf46 ("dccp: Print deprecation notice.").

Since then, only one individual has contacted the netdev mailing list. [0]

There is ongoing research for Multipath DCCP.  The repository is hosted
on GitHub [1], and development is not taking place through the upstream
community.  While the repository is published under the GPLv2 license,
the scheduling part remains proprietary, with a LICENSE file [2] stating:

  "This is not Open Source software."

The researcher mentioned a plan to address the licensing issue, upstream
the patches, and step up as a maintainer, but there has been no further
communication since then.

Maintaining DCCP for a decade without any real users has become a burden.

Therefore, it's time to remove it.

Removing DCCP will also provide significant benefits to TCP.  It allows
us to freely reorganize the layout of struct inet_connection_sock, which
is currently shared with DCCP, and optimize it to reduce the number of
cachelines accessed in the TCP fast path.

Note that we keep DCCP netfilter modules as requested.  [3]

4f0145e9ea docs/zh_CN: Add how-to of Chinese translation
Many new faces keep appearing on the mailing list from time to
time, and there may be many potential developers who want to
participate in the Chinese translation but don't know how to
get started. As more and more documents are translated, it is
becoming increasingly important to improve the maintainability
of Chinese documents. We have a lot of conventions, but currently
these conventions are still being passed on orally. At the same
time, during the review process, especially for the first few
patches submitted by newbies, we have made too many repetitive
comments. In order to address the above issues, I have drafted
this guide, and there is still a lot that needs to be improved.

Linus Torvalds
eb0ece1602 - The 6 patch series "Enable strict percpu address space checks" from
Uros Bizjak uses x86 named address space qualifiers to provide
   compile-time checking of percpu area accesses.
 
   This has caused a small amount of fallout - two or three issues were
   reported.  In all cases the calling code was founf to be incorrect.
 
 - The 4 patch series "Some cleanup for memcg" from Chen Ridong
   implements some relatively monir cleanups for the memcontrol code.
 
 - The 17 patch series "mm: fixes for device-exclusive entries (hmm)"
   from David Hildenbrand fixes a boatload of issues which David found then
   using device-exclusive PTE entries when THP is enabled.  More work is
   needed, but this makes thins better - our own HMM selftests now succeed.
 
 - The 2 patch series "mm: zswap: remove z3fold and zbud" from Yosry
   Ahmed remove the z3fold and zbud implementations.  They have been
   deprecated for half a year and nobody has complained.
 
 - The 5 patch series "mm: further simplify VMA merge operation" from
   Lorenzo Stoakes implements numerous simplifications in this area.  No
   runtime effects are anticipated.
 
 - The 4 patch series "mm/madvise: remove redundant mmap_lock operations
   from process_madvise()" from SeongJae Park rationalizes the locking in
   the madvise() implementation.  Performance gains of 20-25% were observed
   in one MADV_DONTNEED microbenchmark.
 
 - The 12 patch series "Tiny cleanup and improvements about SWAP code"
   from Baoquan He contains a number of touchups to issues which Baoquan
   noticed when working on the swap code.
 
 - The 2 patch series "mm: kmemleak: Usability improvements" from Catalin
   Marinas implements a couple of improvements to the kmemleak user-visible
   output.
 
 - The 2 patch series "mm/damon/paddr: fix large folios access and
   schemes handling" from Usama Arif provides a couple of fixes for DAMON's
   handling of large folios.
 
 - The 3 patch series "mm/damon/core: fix wrong and/or useless
   damos_walk() behaviors" from SeongJae Park fixes a few issues with the
   accuracy of kdamond's walking of DAMON regions.
 
 - The 3 patch series "expose mapping wrprotect, fix fb_defio use" from
   Lorenzo Stoakes changes the interaction between framebuffer deferred-io
   and core MM.  No functional changes are anticipated - this is
   preparatory work for the future removal of page structure fields.
 
 - The 4 patch series "mm/damon: add support for hugepage_size DAMOS
   filter" from Usama Arif adds a DAMOS filter which permits the filtering
   by huge page sizes.
 
 - The 4 patch series "mm: permit guard regions for file-backed/shmem
   mappings" from Lorenzo Stoakes extends the guard region feature from its
   present "anon mappings only" state.  The feature now covers shmem and
   file-backed mappings.
 
 - The 4 patch series "mm: batched unmap lazyfree large folios during
   reclamation" from Barry Song cleans up and speeds up the unmapping for
   pte-mapped large folios.
 
 - The 18 patch series "reimplement per-vma lock as a refcount" from
   Suren Baghdasaryan puts the vm_lock back into the vma.  Our reasons for
   pulling it out were largely bogus and that change made the code more
   messy.  This patchset provides small (0-10%) improvements on one
   microbenchmark.
 
 - The 5 patch series "Docs/mm/damon: misc DAMOS filters documentation
   fixes and improves" from SeongJae Park does some maintenance work on the
   DAMON docs.
 
 - The 27 patch series "hugetlb/CMA improvements for large systems" from
   Frank van der Linden addresses a pile of issues which have been observed
   when using CMA on large machines.
 
 - The 2 patch series "mm/damon: introduce DAMOS filter type for unmapped
   pages" from SeongJae Park enables users of DMAON/DAMOS to filter my the
   page's mapped/unmapped status.
 
 - The 19 patch series "zsmalloc/zram: there be preemption" from Sergey
   Senozhatsky teaches zram to run its compression and decompression
   operations preemptibly.
 
 - The 12 patch series "selftests/mm: Some cleanups from trying to run
   them" from Brendan Jackman fixes a pile of unrelated issues which
   Brendan encountered while runnimg our selftests.
 
 - The 2 patch series "fs/proc/task_mmu: add guard region bit to pagemap"
   from Lorenzo Stoakes permits userspace to use /proc/pid/pagemap to
   determine whether a particular page is a guard page.
 
 - The 7 patch series "mm, swap: remove swap slot cache" from Kairui Song
   removes the swap slot cache from the allocation path - it simply wasn't
   being effective.
 
 - The 5 patch series "mm: cleanups for device-exclusive entries (hmm)"
   from David Hildenbrand implements a number of unrelated cleanups in this
   code.
 
 - The 5 patch series "mm: Rework generic PTDUMP configs" from Anshuman
   Khandual implements a number of preparatoty cleanups to the
   GENERIC_PTDUMP Kconfig logic.
 
 - The 8 patch series "mm/damon: auto-tune aggregation interval" from
   SeongJae Park implements a feedback-driven automatic tuning feature for
   DAMON's aggregation interval tuning.
 
 - The 5 patch series "Fix lazy mmu mode" from Ryan Roberts fixes some
   issues in powerpc, sparc and x86 lazy MMU implementations.  Ryan did
   this in preparation for implementing lazy mmu mode for arm64 to optimize
   vmalloc.
 
 - The 2 patch series "mm/page_alloc: Some clarifications for migratetype
   fallback" from Brendan Jackman reworks some commentary to make the code
   easier to follow.
 
 - The 3 patch series "page_counter cleanup and size reduction" from
   Shakeel Butt cleans up the page_counter code and fixes a size increase
   which we accidentally added late last year.
 
 - The 3 patch series "Add a command line option that enables control of
   how many threads should be used to allocate huge pages" from Thomas
   Prescher does that.  It allows the careful operator to significantly
   reduce boot time by tuning the parallalization of huge page
   initialization.
 
 - The 3 patch series "Fix calculations in trace_balance_dirty_pages()
   for cgwb" from Tang Yizhou fixes the tracing output from the dirty page
   balancing code.
 
 - The 9 patch series "mm/damon: make allow filters after reject filters
   useful and intuitive" from SeongJae Park improves the handling of allow
   and reject filters.  Behaviour is made more consistent and the
   documention is updated accordingly.
 
 - The 5 patch series "Switch zswap to object read/write APIs" from Yosry
   Ahmed updates zswap to the new object read/write APIs and thus permits
   the removal of some legacy code from zpool and zsmalloc.
 
 - The 6 patch series "Some trivial cleanups for shmem" from Baolin Wang
   does as it claims.
 
 - The 20 patch series "fs/dax: Fix ZONE_DEVICE page reference counts"
   from Alistair Popple regularizes the weird ZONE_DEVICE page refcount
   handling in DAX, permittig the removal of a number of special-case
   checks.
 
 - The 4 patch series "refactor mremap and fix bug" from Lorenzo Stoakes
   is a preparatoty refactoring and cleanup of the mremap() code.
 
 - The 20 patch series "mm: MM owner tracking for large folios (!hugetlb)
   + CONFIG_NO_PAGE_MAPCOUNT" from David Hildenbrand reworks the manner in
   which we determine whether a large folio is known to be mapped
   exclusively into a single MM.
 
 - The 8 patch series "mm/damon: add sysfs dirs for managing DAMOS
   filters based on handling layers" from SeongJae Park adds a couple of
   new sysfs directories to ease the management of DAMON/DAMOS filters.
 
 - The 13 patch series "arch, mm: reduce code duplication in mem_init()"
   from Mike Rapoport consolidates many per-arch implementations of
   mem_init() into code generic code, where that is practical.
 
 - The 13 patch series "mm/damon/sysfs: commit parameters online via
   damon_call()" from SeongJae Park continues the cleaning up of sysfs
   access to DAMON internal data.
 
 - The 3 patch series "mm: page_ext: Introduce new iteration API" from
   Luiz Capitulino reworks the page_ext initialization to fix a boot-time
   crash which was observed with an unusual combination of compile and
   cmdline options.
 
 - The 8 patch series "Buddy allocator like (or non-uniform) folio split"
   from Zi Yan reworks the code to split a folio into smaller folios.  The
   main benefit is lessened memory consumption: fewer post-split folios are
   generated.
 
 - The 2 patch series "Minimize xa_node allocation during xarry split"
   from Zi Yan reduces the number of xarray xa_nodes which are generated
   during an xarray split.
 
 - The 2 patch series "drivers/base/memory: Two cleanups" from Gavin Shan
   performs some maintenance work on the drivers/base/memory code.

Merge tag 'mm-stable-2025-03-30-16-52' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Pull MM updates from Andrew Morton:

 - The series "Enable strict percpu address space checks" from Uros
   Bizjak uses x86 named address space qualifiers to provide
   compile-time checking of percpu area accesses.

   This has caused a small amount of fallout - two or three issues were
   reported. In all cases the calling code was found to be incorrect.

 - The series "Some cleanup for memcg" from Chen Ridong implements some
   relatively monir cleanups for the memcontrol code.

 - The series "mm: fixes for device-exclusive entries (hmm)" from David
   Hildenbrand fixes a boatload of issues which David found then using
   device-exclusive PTE entries when THP is enabled. More work is
   needed, but this makes thins better - our own HMM selftests now
   succeed.

 - The series "mm: zswap: remove z3fold and zbud" from Yosry Ahmed
   remove the z3fold and zbud implementations. They have been deprecated
   for half a year and nobody has complained.

 - The series "mm: further simplify VMA merge operation" from Lorenzo
   Stoakes implements numerous simplifications in this area. No runtime
   effects are anticipated.

 - The series "mm/madvise: remove redundant mmap_lock operations from
   process_madvise()" from SeongJae Park rationalizes the locking in the
   madvise() implementation. Performance gains of 20-25% were observed
   in one MADV_DONTNEED microbenchmark.

 - The series "Tiny cleanup and improvements about SWAP code" from
   Baoquan He contains a number of touchups to issues which Baoquan
   noticed when working on the swap code.

 - The series "mm: kmemleak: Usability improvements" from Catalin
   Marinas implements a couple of improvements to the kmemleak
   user-visible output.

 - The series "mm/damon/paddr: fix large folios access and schemes
   handling" from Usama Arif provides a couple of fixes for DAMON's
   handling of large folios.

 - The series "mm/damon/core: fix wrong and/or useless damos_walk()
   behaviors" from SeongJae Park fixes a few issues with the accuracy of
   kdamond's walking of DAMON regions.

 - The series "expose mapping wrprotect, fix fb_defio use" from Lorenzo
   Stoakes changes the interaction between framebuffer deferred-io and
   core MM. No functional changes are anticipated - this is preparatory
   work for the future removal of page structure fields.

 - The series "mm/damon: add support for hugepage_size DAMOS filter"
   from Usama Arif adds a DAMOS filter which permits the filtering by
   huge page sizes.

 - The series "mm: permit guard regions for file-backed/shmem mappings"
   from Lorenzo Stoakes extends the guard region feature from its
   present "anon mappings only" state. The feature now covers shmem and
   file-backed mappings.

 - The series "mm: batched unmap lazyfree large folios during
   reclamation" from Barry Song cleans up and speeds up the unmapping
   for pte-mapped large folios.

 - The series "reimplement per-vma lock as a refcount" from Suren
   Baghdasaryan puts the vm_lock back into the vma. Our reasons for
   pulling it out were largely bogus and that change made the code more
   messy. This patchset provides small (0-10%) improvements on one
   microbenchmark.

 - The series "Docs/mm/damon: misc DAMOS filters documentation fixes and
   improves" from SeongJae Park does some maintenance work on the DAMON
   docs.

 - The series "hugetlb/CMA improvements for large systems" from Frank
   van der Linden addresses a pile of issues which have been observed
   when using CMA on large machines.

 - The series "mm/damon: introduce DAMOS filter type for unmapped pages"
   from SeongJae Park enables users of DMAON/DAMOS to filter my the
   page's mapped/unmapped status.

 - The series "zsmalloc/zram: there be preemption" from Sergey
   Senozhatsky teaches zram to run its compression and decompression
   operations preemptibly.

 - The series "selftests/mm: Some cleanups from trying to run them" from
   Brendan Jackman fixes a pile of unrelated issues which Brendan
   encountered while runnimg our selftests.

 - The series "fs/proc/task_mmu: add guard region bit to pagemap" from
   Lorenzo Stoakes permits userspace to use /proc/pid/pagemap to
   determine whether a particular page is a guard page.

 - The series "mm, swap: remove swap slot cache" from Kairui Song
   removes the swap slot cache from the allocation path - it simply
   wasn't being effective.

 - The series "mm: cleanups for device-exclusive entries (hmm)" from
   David Hildenbrand implements a number of unrelated cleanups in this
   code.

 - The series "mm: Rework generic PTDUMP configs" from Anshuman Khandual
   implements a number of preparatoty cleanups to the GENERIC_PTDUMP
   Kconfig logic.

 - The series "mm/damon: auto-tune aggregation interval" from SeongJae
   Park implements a feedback-driven automatic tuning feature for
   DAMON's aggregation interval tuning.

 - The series "Fix lazy mmu mode" from Ryan Roberts fixes some issues in
   powerpc, sparc and x86 lazy MMU implementations. Ryan did this in
   preparation for implementing lazy mmu mode for arm64 to optimize
   vmalloc.

 - The series "mm/page_alloc: Some clarifications for migratetype
   fallback" from Brendan Jackman reworks some commentary to make the
   code easier to follow.

 - The series "page_counter cleanup and size reduction" from Shakeel
   Butt cleans up the page_counter code and fixes a size increase which
   we accidentally added late last year.

 - The series "Add a command line option that enables control of how
   many threads should be used to allocate huge pages" from Thomas
   Prescher does that. It allows the careful operator to significantly
   reduce boot time by tuning the parallalization of huge page
   initialization.

 - The series "Fix calculations in trace_balance_dirty_pages() for cgwb"
   from Tang Yizhou fixes the tracing output from the dirty page
   balancing code.

 - The series "mm/damon: make allow filters after reject filters useful
   and intuitive" from SeongJae Park improves the handling of allow and
   reject filters. Behaviour is made more consistent and the documention
   is updated accordingly.

 - The series "Switch zswap to object read/write APIs" from Yosry Ahmed
   updates zswap to the new object read/write APIs and thus permits the
   removal of some legacy code from zpool and zsmalloc.

 - The series "Some trivial cleanups for shmem" from Baolin Wang does as
   it claims.

 - The series "fs/dax: Fix ZONE_DEVICE page reference counts" from
   Alistair Popple regularizes the weird ZONE_DEVICE page refcount
   handling in DAX, permittig the removal of a number of special-case

   preparatoty refactoring and cleanup of the mremap() code.

 - The series "mm: MM owner tracking for large folios (!hugetlb) +
   CONFIG_NO_PAGE_MAPCOUNT" from David Hildenbrand reworks the manner in
   which we determine whether a large folio is known to be mapped
   exclusively into a single MM.

 - The series "mm/damon: add sysfs dirs for managing DAMOS filters based
   on handling layers" from SeongJae Park adds a couple of new sysfs
   directories to ease the management of DAMON/DAMOS filters.

 - The series "arch, mm: reduce code duplication in mem_init()" from
   Mike Rapoport consolidates many per-arch implementations of
   mem_init() into code generic code, where that is practical.

 - The series "mm/damon/sysfs: commit parameters online via
   damon_call()" from SeongJae Park continues the cleaning up of sysfs
   access to DAMON internal data.

 - The series "mm: page_ext: Introduce new iteration API" from Luiz
   Capitulino reworks the page_ext initialization to fix a boot-time
   crash which was observed with an unusual combination of compile and
   cmdline options.

 - The series "Buddy allocator like (or non-uniform) folio split" from
   Zi Yan reworks the code to split a folio into smaller folios. The
   main benefit is lessened memory consumption: fewer post-split folios
   are generated.

 - The series "Minimize xa_node allocation during xarry split" from Zi
   Yan reduces the number of xarray xa_nodes which are generated during
   an xarray split.

 - The series "drivers/base/memory: Two cleanups" from Gavin Shan
