79952bdcbc f2fs-6.12-rc1 
In this series, the main changes include 1) converting major IO paths to use
 folio, and 2) adding various knobs to control GC more flexibly for Zoned
 devices. In addition, there are several patches to address corner cases of
 atomic file operations and better support for file pinning on zoned device.
 
 Enhancement:
  - add knobs to tune foreground/background GCs for Zoned devices
  - convert IO paths to use folio
  - reduce expensive checkpoint trigger frequency
  - allow F2FS_IPU_NOCACHE for pinned file
  - forcibly migrate to secure space for zoned device file pinning
  - get rid of buffer_head use
  - add write priority option based on zone UFS
  - get rid of online repair on corrupted directory
 
 Bug fix:
  - fix to don't panic system for no free segment fault injection
  - fix to don't set SB_RDONLY in f2fs_handle_critical_error()
  - avoid unused block when dio write in LFS mode
  - compress: don't redirty sparse cluster during {,de}compress
  - check discard support for conventional zones
  - atomic: prevent atomic file from being dirtied before commit
  - atomic: fix to check atomic_file in f2fs ioctl interfaces
  - atomic: fix to forbid dio in atomic_file
  - atomic: fix to truncate pagecache before on-disk metadata truncation
  - atomic: create COW inode from parent dentry
  - atomic: fix to avoid racing w/ GC
  - atomic: require FMODE_WRITE for atomic write ioctls
  - fix to wait page writeback before setting gcing flag
  - fix to avoid racing in between read and OPU dio write, dio completion
  - fix several potential integer overflows in file offsets and dir_block_index
  - fix to avoid use-after-free in f2fs_stop_gc_thread()
 
 As usual, there are several code clean-ups and refactorings.

Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Wait for device readiness after reset by polling Vendor ID and
     looking for Configuration RRS instead of polling the Command
     register and looking for non-error completions, to avoid hardware
     retries done for RRS on non-Vendor ID reads (Bjorn Helgaas)

   - Rename CRS Completion Status to RRS ('Request Retry Status') to
     match PCIe r6.0 spec usage (Bjorn Helgaas)

   - Clear LBMS bit after a manual link retrain so we don't try to
     retrain a link when there's no downstream device anymore (Maciej W.
     Rozycki)

   - Revert to the original link speed after retraining fails instead of
     leaving it restricted to 2.5GT/s, so a future device has a chance
     to use higher speeds (Maciej W. Rozycki)

   - Wait for each level of downstream bus, not just the first, to
     become accessible before restoring devices on that bus (Ilpo
     Järvinen)

   - Add ARCH_PCI_DEV_GROUPS so s390 can add its own attribute_groups
     without having to stomp on the core's pdev->dev.groups (Lukas
     Wunner)

  Driver binding:

   - Export pcim_request_region(), a managed counterpart of
     pci_request_region(), for use by drivers (Philipp Stanner)

   - Export pcim_iomap_region() and deprecate pcim_iomap_regions()
     (Philipp Stanner)

   - Request the PCI BAR used by xboxvideo (Philipp Stanner)

   - Request and map drm/ast BARs with pcim_iomap_region() (Philipp

     single IRQ line and cannot set the affinity of each MSI to a
     specific CPU core (Marek Vasut)

   - Use MSI_FLAG_NO_AFFINITY and remove unnecessary .irq_set_affinity()
     implementations in aardvark, altera, brcmstb, dwc, mediatek-gen3,
     mediatek, mobiveil, plda, rcar, tegra, vmd, xilinx-nwl,
     xilinx-xdma, and xilinx drivers to avoid 'IRQ: set affinity failed'
     warnings (Marek Vasut)

  Power management:

   - Add pwrctl support for ATH11K inside the WCN6855 package (Konrad
     Dybcio)

  PCI device hotplug:

     control of NVMe RAID storage indicators (ok/fail/locate/
     rebuild/etc) (Mariusz Tkaczyk)

   - Add support for the ACPI _DSM PCIe SSD status LED management, which
     is functionally similar to NPEM but mediated by platform firmware
     (Mariusz Tkaczyk)

  Device trees:

   - Drop minItems and maxItems from ranges in PCI generic host binding
     since host bridges may have several MMIO and I/O port apertures
     (Frank Li)

   - Add kirin, rcar-gen2, uniphier DT binding top-level constraints for
     clocks (Krzysztof Kozlowski)

  Altera PCIe controller driver:

   - Convert altera DT bindings from text to YAML (Matthew Gerlach)

   - Replace TLP_REQ_ID() with macro PCI_DEVID(), which does the same
     thing and is what other drivers use (Jinjie Ruan)

  Broadcom STB PCIe controller driver:

   - Add DT binding maxItems for reset controllers (Jim Quinlan)

   - Use the 'bridge' reset method if described in the DT (Jim Quinlan)

   - Use the 'swinit' reset method if described in the DT (Jim Quinlan)

     Endpoints to fail to establish link (Richard Zhu)

   - Fix i.MX8MP Endpoint occasional failure to trigger MSI by enforcing
     outbound alignment requirement (Richard Zhu)

   - Call phy_power_off() in the .probe() error path (Frank Li)

   - Rename internal names from imx6_* to imx_* since i.MX7/8/9 are also
     supported (Frank Li)

   - Manage Refclk by using SoC-specific callbacks instead of switch
     statements (Frank Li)

   - Manage core reset by using SoC-specific callbacks instead of switch
     statements (Frank Li)

   - Expand comments for erratum ERR010728 workaround (Frank Li)

   - Use generic PHY APIs to configure mode, speed, and submode, which
     is harmless for devices that implement their own internal PHY
     management and don't set the generic imx_pcie->phy (Frank Li)

   - Add i.MX8Q (i.MX8QM, i.MX8QXP, and i.MX8DXL) DT binding and driver
     Root Complex support (Richard Zhu)

     Sadhasivam)

   - Clarify unknown global IRQ message and only log it once to avoid a
     flood (Manivannan Sadhasivam)

617a814f14 ALong with the usual shower of singleton patches, notable patch series in 
this pull request are:
 
 "Align kvrealloc() with krealloc()" from Danilo Krummrich.  Adds
 consistency to the APIs and behaviour of these two core allocation
 functions.  This also simplifies/enables Rustification.
 
 "Some cleanups for shmem" from Baolin Wang.  No functional changes - mode
 code reuse, better function naming, logic simplifications.
 
 "mm: some small page fault cleanups" from Josef Bacik.  No functional
 changes - code cleanups only.
 
 "Various memory tiering fixes" from Zi Yan.  A small fix and a little
 cleanup.
 
 "mm/swap: remove boilerplate" from Yu Zhao.  Code cleanups and
 simplifications and .text shrinkage.
 
 "Kernel stack usage histogram" from Pasha Tatashin and Shakeel Butt.  This
 is a feature, it adds new feilds to /proc/vmstat such as
 
     $ grep kstack /proc/vmstat
     kstack_1k 3
     kstack_2k 188
     kstack_4k 11391
     kstack_8k 243
     kstack_16k 0
 
 which tells us that 11391 processes used 4k of stack while none at all
 used 16k.  Useful for some system tuning things, but partivularly useful
 for "the dynamic kernel stack project".
 
 "kmemleak: support for percpu memory leak detect" from Pavel Tikhomirov.
 Teaches kmemleak to detect leaksage of percpu memory.
 
 "mm: memcg: page counters optimizations" from Roman Gushchin.  "3
 independent small optimizations of page counters".
 
 "mm: split PTE/PMD PT table Kconfig cleanups+clarifications" from David
 Hildenbrand.  Improves PTE/PMD splitlock detection, makes powerpc/8xx work
 correctly by design rather than by accident.
 
 "mm: remove arch_make_page_accessible()" from David Hildenbrand.  Some
 folio conversions which make arch_make_page_accessible() unneeded.
 
 "mm, memcg: cg2 memory{.swap,}.peak write handlers" fro David Finkel.
 Cleans up and fixes our handling of the resetting of the cgroup/process
 peak-memory-use detector.
 
 "Make core VMA operations internal and testable" from Lorenzo Stoakes.
 Rationalizaion and encapsulation of the VMA manipulation APIs.  With a
 view to better enable testing of the VMA functions, even from a
 userspace-only harness.
 
 "mm: zswap: fixes for global shrinker" from Takero Funaki.  Fix issues in
 the zswap global shrinker, resulting in improved performance.
 
 "mm: print the promo watermark in zoneinfo" from Kaiyang Zhao.  Fill in
 some missing info in /proc/zoneinfo.
 
 "mm: replace follow_page() by folio_walk" from David Hildenbrand.  Code
 cleanups and rationalizations (conversion to folio_walk()) resulting in
 the removal of follow_page().
 
 "improving dynamic zswap shrinker protection scheme" from Nhat Pham.  Some
 tuning to improve zswap's dynamic shrinker.  Significant reductions in
 swapin and improvements in performance are shown.
 
 "mm: Fix several issues with unaccepted memory" from Kirill Shutemov.
 Improvements to the new unaccepted memory feature,
 
 "mm/mprotect: Fix dax puds" from Peter Xu.  Implements mprotect on DAX
 PUDs.  This was missing, although nobody seems to have notied yet.
 
 "Introduce a store type enum for the Maple tree" from Sidhartha Kumar.
 Cleanups and modest performance improvements for the maple tree library
 code.
 
 "memcg: further decouple v1 code from v2" from Shakeel Butt.  Move more
 cgroup v1 remnants away from the v2 memcg code.
 
 "memcg: initiate deprecation of v1 features" from Shakeel Butt.  Adds
 various warnings telling users that memcg v1 features are deprecated.
 
 "mm: swap: mTHP swap allocator base on swap cluster order" from Chris Li.
 Greatly improves the success rate of the mTHP swap allocation.
 
 "mm: introduce numa_memblks" from Mike Rapoport.  Moves various disparate
 per-arch implementations of numa_memblk code into generic code.
 
 "mm: batch free swaps for zap_pte_range()" from Barry Song.  Greatly
 improves the performance of munmap() of swap-filled ptes.
 
 "support large folio swap-out and swap-in for shmem" from Baolin Wang.
 With this series we no longer split shmem large folios into simgle-page
 folios when swapping out shmem.
 
 "mm/hugetlb: alloc/free gigantic folios" from Yu Zhao.  Nice performance
 improvements and code reductions for gigantic folios.
 
 "support shmem mTHP collapse" from Baolin Wang.  Adds support for
 khugepaged's collapsing of shmem mTHP folios.
 
 "mm: Optimize mseal checks" from Pedro Falcato.  Fixes an mprotect()
 performance regression due to the addition of mseal().
 
 "Increase the number of bits available in page_type" from Matthew Wilcox.
 Increases the number of bits available in page_type!
 
 "Simplify the page flags a little" from Matthew Wilcox.  Many legacy page
 flags are now folio flags, so the page-based flags and their
 accessors/mutators can be removed.
 
 "mm: store zero pages to be swapped out in a bitmap" from Usama Arif.  An
 optimization which permits us to avoid writing/reading zero-filled zswap
 pages to backing store.
 
 "Avoid MAP_FIXED gap exposure" from Liam Howlett.  Fixes a race window
 which occurs when a MAP_FIXED operqtion is occurring during an unrelated
 vma tree walk.
 
 "mm: remove vma_merge()" from Lorenzo Stoakes.  Major rotorooting of the
 vma_merge() functionality, making ot cleaner, more testable and better
 tested.

a1d1eb2f57 SCSI misc on 20240919 
Updates to the usual drivers (ufs, smartpqi, NCR5380, mac_scsi, lpfc,
 mpi3mr).  There are no user visible core changes and a whole series of
 minor updates and fixes.  The largest core change is probably the
 simplification of the workqueue allocation path.

Pull random number generator updates from Jason Donenfeld:
 "Originally I'd planned on sending each of the vDSO getrandom()
  architecture ports to their respective arch trees. But as we started
  to work on this, we found lots of interesting issues in the shared
  code and infrastructure, the fixes for which the various archs needed
  to base their work.

  So in the end, this turned into a nice collaborative effort fixing up
  issues and porting to 5 new architectures -- arm64, powerpc64,
  powerpc32, s390x, and loongarch64 -- with everybody pitching in and
  commenting on each other's code. It was a fun development cycle.

  This contains:

   - Numerous fixups to the vDSO selftest infrastructure, getting it
     running successfully on more platforms, and fixing bugs in it.

   - Additions to the vDSO getrandom & chacha selftests. Basically every
     time manual review unearthed a bug in a revision of an arch patch,
     or an ambiguity, the tests were augmented.

     By the time the last arch was submitted for review, s390x, v1 of
     the series was essentially fine right out of the gate.

   - Fixes to the the generic C implementation of vDSO getrandom, to
     build and run successfully on all archs, decoupling it from
     assumptions we had (unintentionally) made on x86_64 that didn't
     carry through to the other architectures.

   - Port of vDSO getrandom to LoongArch64, from Xi Ruoyao and acked by
     Huacai Chen.

   - Port of vDSO getrandom to ARM64, from Adhemerval Zanella and acked
     by Will Deacon.

   - Port of vDSO getrandom to PowerPC, in both 32-bit and 64-bit
     varieties, from Christophe Leroy and acked by Michael Ellerman.

   - Port of vDSO getrandom to S390X from Heiko Carstens, the arch
     maintainer.

  While it'd be natural for there to be things to fix up over the course
  of the development cycle, these patches got a decent amount of review
  from a fairly diverse crew of folks on the mailing lists, and, for the
  most part, they've been cooking in linux-next, which has been helpful
  for ironing out build issues.

  In terms of architectures, I think that mostly takes care of the
  important 64-bit archs with hardware still being produced and running
  production loads in settings where vDSO getrandom is likely to help.

  Arguably there's still RISC-V left, and we'll see for 6.13 whether
  they find it useful and submit a port"

759ec28242 PCI/NPEM: Add _DSM PCIe SSD status LED management 
The PCIe SSD Status LED Management _DSM defined in PCI Firmware Spec r3.3
sec 4.7 provides a way to manage LEDs via ACPI.

The design is similar to NPEM defined in PCIe Base Specification r6.1 sec
6.28:

  - Both standards are indication oriented,

  - _DSM supported bits correspond to NPEM capability register bits,

  - _DSM control bits correspond to NPEM control register bits.

_DSM does not support enclosure-specific indications or the special NPEM
commands NPEM_ENABLE and NPEM_RESET.

_DSM is implemented as a second backend in NPEM driver. The backend used is
logged with info priority. The same sysfs interface is used for both NPEM
and _DSM.

According to spec, _DSM has higher priority, and availability  of _DSM in
not limited to devices with NPEM support.

The Dell implementation of DSM uses acpi ipmi, which may not be available
immediately (in fact it may take up to 10s for this interface to be
available). It can determine if DSM is supported (GET_SUPPORTED_STATES_DSM
is working) but it cannot serve GET_STATE_DSM or SET_STATE_DSM commands in
this time.

From userspace application perspective (primarily configured by systemd
service) it is better to have not working but configured interface rather
than have it available after few seconds.

For that reason, npem->active_indications cache is now loaded lazily, i.e.
any GET or SET request want cache to be updated if it is not done yet.

4e893545ef PCI/NPEM: Add Native PCIe Enclosure Management support 
Native PCIe Enclosure Management (NPEM, PCIe r6.1 sec 6.28) allows managing
LEDs in storage enclosures. NPEM is indication oriented and it does not
give direct access to LEDs. Although each indication *could* represent an
individual LED, multiple indications could also be represented as a single,
multi-color LED or a single LED blinking in a specific interval.  The
specification leaves that open.

Each enabled indication (capability register bit on) is represented as a
ledclass_dev which can be controlled through sysfs. For every ledclass
device only 2 brightness states are allowed: LED_ON (1) or LED_OFF (0).
This corresponds to the NPEM control register (Indication bit on/off).

Ledclass devices appear in sysfs as child devices (subdirectory) of PCI
device which has an NPEM Extended Capability and indication is enabled in
NPEM capability register. For example, these are LEDs created for pcieport
"10000:02:05.0" on my setup:

  leds/
  ├── 10000:02:05.0:enclosure:fail
  ├── 10000:02:05.0:enclosure:locate
  ├── 10000:02:05.0:enclosure:ok
  └── 10000:02:05.0:enclosure:rebuild

They can be also found in "/sys/class/leds" directory. The parent PCIe
device domain/bus/device/function address is used to guarantee uniqueness
across leds subsystem.

To enable/disable a "fail" indication, the "brightness" file can be edited:

  echo 1 > ./leds/10000:02:05.0:enclosure:fail/brightness
  echo 0 > ./leds/10000:02:05.0:enclosure:fail/brightness

PCIe r6.1, sec 7.9.19.2 defines the possible indications.

Multiple indications for same parent PCIe device can conflict and hardware
may update them when processing new request. To avoid issues, driver
refresh all indications by reading back control register.

This driver expects to be the exclusive NPEM extended capability manager.
It waits up to 1 second after imposing new request, it doesn't verify if
controller is busy before write, and it assumes the mutex lock gives
protection from concurrent updates.

If _DSM LED management is available, we assume the platform may be using
NPEM for its own purposes (see PCI Firmware Spec r3.3 sec 4.7), so the
driver does not use NPEM. A future patch will add _DSM support; an info
message notes whether NPEM or _DSM is being used.

NPEM is a PCIe extended capability so it should be registered in
pcie_init_capabilities() but it is not possible due to LED dependency.  The
parent pci_device must be added earlier for led_classdev_register() to be
successful. NPEM does not require configuration on kernel side, so it is
safe to register LED devices later.

0d9af1e1c9 power: supply: "usb_type" property may be written to 
According to Documentation/ABI/testing/sysfs-class-power the "usb_type"
property is Read-Only.

For power-supplies which consume USB power such as battery charger chips,
this is correct.

But the UCS1002 USB Port Power Controller driver which is a driver
for a chip which is a power-source for USB-A charging ports "usb_type"
is actually writable to configure the type of USB charger emulated
by the USB-A port.

Adjust the docs and the power_supply_sysfs.c code to adjust for this
new writeable use of "usb_type":

1. Update Documentation/ABI/testing/sysfs-class-power to document that
"usb_type" may be writable

2. Change the power_supply_attr type in power_supply_sysfs.c from
POWER_SUPPLY_ATTR() into POWER_SUPPLY_ENUM_ATTR() so that the various
usb_type string values from POWER_SUPPLY_TYPE_TEXT[] such as e.g.
"SDP" and "USB_PD" can be written to the "usb_type" attribute instead
of only accepting integer values.

[FAIL]	No such clock, but __vdso_clock_gettime returned 22

On powerpc, a call to a VDSO function is not an ordinary C function
call. Unlike several architectures which returns a negative error code
in case of an error, powerpc sets CR[SO] and returns the error code
as a positive value.

Define and use a macro called VDSO_CALL() which takes a pointer
to the function to call, the number of arguments and the arguments.

Also update ABI vdso documentation to reflect this subtlety.

Provide a specific version of VDSO_CALL() for powerpc that negates
the error code on return when CR[SO] is set.

Adds support in the OP-TEE drivers (both SMC and FF-A ABIs) to probe and
use an RPMB device via the RPMB subsystem instead of passing the RPMB
frames via tee-supplicant in user space. A fallback mechanism is kept to
route RPMB frames via tee-supplicant if the RPMB subsystem isn't
available.

The OP-TEE RPC ABI is extended to support iterating over all RPMB
devices until one is found with the expected RPMB key already
programmed.

6c17ea1f3e cpu/SMT: Enable SMT only if a core is online 
If a core is offline then enabling SMT should not online CPUs of
this core. By enabling SMT, what is intended is either changing the SMT
value from "off" to "on" or setting the SMT level (threads per core) from a
lower to higher value.

On PowerPC the ppc64_cpu utility can be used, among other things, to
perform the following functions:

ppc64_cpu --cores-on                # Get the number of online cores
ppc64_cpu --cores-on=X              # Put exactly X cores online
ppc64_cpu --offline-cores=X[,Y,...] # Put specified cores offline
ppc64_cpu --smt={on|off|value}      # Enable, disable or change SMT level

If the user has decided to offline certain cores, enabling SMT should
not online CPUs in those cores. This patch fixes the issue and changes
the behaviour as described, by introducing an arch specific function
topology_is_core_online(). It is currently implemented only for PowerPC.

8444ce5249 f2fs: add write priority option based on zone UFS 
Currently, we are using a mix of traditional UFS and zone UFS to support
some functionalities that cannot be achieved on zone UFS alone. However,
there are some issues with this approach. There exists a significant
performance difference between traditional UFS and zone UFS. Under normal
usage, we prioritize writes to zone UFS. However, in critical conditions
(such as when the entire UFS is almost full), we cannot determine whether
data will be written to traditional UFS or zone UFS. This can lead to
significant performance fluctuations, which is not conducive to
development and testing. To address this, we have added an option
zlu_io_enable under sys with the following three modes:
1) zlu_io_enable == 0:Normal mode, prioritize writing to zone UFS;
2) zlu_io_enable == 1:Zone UFS only mode, only allow writing to zone UFS;
3) zlu_io_enable == 2:Traditional UFS priority mode, prioritize writing to
traditional UFS.

Merge tag 'cxl-for-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl

Pull CXL updates from Dave Jiang:
 "Core:

   - A CXL maturity map has been added to the documentation to detail
     the current state of CXL enabling.

     It provides the status of the current state of various CXL features
     to inform current and future contributors of where things are and
     which areas need contribution.

   - A notifier handler has been added in order for a newly created CXL
     memory region to trigger the abstract distance metrics calculation.

     This should bring parity for CXL memory to the same level vs
     hotplugged DRAM for NUMA abstract distance calculation. The
     abstract distance reflects relative performance used for memory
     tiering handling.

   - An addition for XOR math has been added to address the CXL DPA to
     SPA translation.

     CXL address translation did not support address interleave math
     with XOR prior to this change.

  Fixes:

   - Fix to address race condition in the CXL memory hotplug notifier

   - Add missing MODULE_DESCRIPTION() for CXL modules

   - Fix incorrect vendor debug UUID define

  Misc:

   - A warning has been added to inform users of an unsupported
     configuration when mixing CXL VH and RCH/RCD hierarchies

   - The ENXIO error code has been replaced with EBUSY for inject poison
     limit reached via debugfs and cxl-test support

   - Moving the PCI config read in cxl_dvsec_rr_decode() to avoid
     unnecessary PCI config reads

   - A refactor to a common struct for DRAM and general media CXL

   Yu has a fix which I'll send along later via the hotfixes branch.
 
 - In the series "mm: Avoid possible overflows in dirty throttling" Jan
   Kara addresses a couple of issues in the writeback throttling code.
   These fixes are also targetted at -stable kernels.
 
 - Ryusuke Konishi's series "nilfs2: fix potential issues related to
   reserved inodes" does that.  This should actually be in the
   mm-nonmm-stable tree, along with the many other nilfs2 patches.  My bad.
 
 - More folio conversions from Kefeng Wang in the series "mm: convert to
   folio_alloc_mpol()"
 
 - Kemeng Shi has sent some cleanups to the writeback code in the series
   "Add helper functions to remove repeated code and improve readability of
   cgroup writeback"
 
 - Kairui Song has made the swap code a little smaller and a little
   faster in the series "mm/swap: clean up and optimize swap cache index".
 
 - In the series "mm/memory: cleanly support zeropage in
   vm_insert_page*(), vm_map_pages*() and vmf_insert_mixed()" David
   Hildenbrand has reworked the rather sketchy handling of the use of the
   zeropage in MAP_SHARED mappings.  I don't see any runtime effects here -
   more a cleanup/understandability/maintainablity thing.
 
 - Dev Jain has improved selftests/mm/va_high_addr_switch.c's handling of
   higher addresses, for aarch64.  The (poorly named) series is
   "Restructure va_high_addr_switch".
 
 - The core TLB handling code gets some cleanups and possible slight
   optimizations in Bang Li's series "Add update_mmu_tlb_range() to
   simplify code".
 
 - Jane Chu has improved the handling of our
   fake-an-unrecoverable-memory-error testing feature MADV_HWPOISON in the
   series "Enhance soft hwpoison handling and injection".
 
 - Jeff Johnson has sent a billion patches everywhere to add
   MODULE_DESCRIPTION() to everything.  Some landed in this pull.
 
 - In the series "mm: cleanup MIGRATE_SYNC_NO_COPY mode", Kefeng Wang has
   simplified migration's use of hardware-offload memory copying.
 
 - Yosry Ahmed performs more folio API conversions in his series "mm:
   zswap: trivial folio conversions".
 
 - In the series "large folios swap-in: handle refault cases first",
   Chuanhua Han inches us forward in the handling of large pages in the
   swap code.  This is a cleanup and optimization, working toward the end
   objective of full support of large folio swapin/out.
 
 - In the series "mm,swap: cleanup VMA based swap readahead window
   calculation", Huang Ying has contributed some cleanups and a possible
   fixlet to his VMA based swap readahead code.
 
 - In the series "add mTHP support for anonymous shmem" Baolin Wang has
   taught anonymous shmem mappings to use multisize THP.  By default this
   is a no-op - users must opt in vis sysfs controls.  Dramatic
   improvements in pagefault latency are realized.
 
 - David Hildenbrand has some cleanups to our remaining use of
   page_mapcount() in the series "fs/proc: move page_mapcount() to
   fs/proc/internal.h".
 
 - David also has some highmem accounting cleanups in the series
   "mm/highmem: don't track highmem pages manually".
 
 - Build-time fixes and cleanups from John Hubbard in the series
   "cleanups, fixes, and progress towards avoiding "make headers"".
 
 - Cleanups and consolidation of the core pagemap handling from Barry
   Song in the series "mm: introduce pmd|pte_needs_soft_dirty_wp helpers
   and utilize them".
 
 - Lance Yang's series "Reclaim lazyfree THP without splitting" has
   reduced the latency of the reclaim of pmd-mapped THPs under fairly
   common circumstances.  A 10x speedup is seen in a microbenchmark.
 
   It does this by punting to aother CPU but I guess that's a win unless
   all CPUs are pegged.
 
 - hugetlb_cgroup cleanups from Xiu Jianfeng in the series
   "mm/hugetlb_cgroup: rework on cftypes".
 
 - Miaohe Lin's series "Some cleanups for memory-failure" does just that
   thing.
 
 - Is anyone reading this stuff?  If so, email me!
 
 - Someone other than SeongJae has developed a DAMON feature in Honggyu
   Kim's series "DAMON based tiered memory management for CXL memory".
   This adds DAMON features which may be used to help determine the
   efficiency of our placement of CXL/PCIe attached DRAM.
 
 - DAMON user API centralization and simplificatio work in SeongJae
   Park's series "mm/damon: introduce DAMON parameters online commit
   function".
 
 - In the series "mm: page_type, zsmalloc and page_mapcount_reset()"
   David Hildenbrand does some maintenance work on zsmalloc - partially
   modernizing its use of pageframe fields.
 
 - Kefeng Wang provides more folio conversions in the series "mm: remove
   page_maybe_dma_pinned() and page_mkclean()".
 
 - More cleanup from David Hildenbrand, this time in the series
   "mm/memory_hotplug: use PageOffline() instead of PageReserved() for
   !ZONE_DEVICE".  It "enlightens memory hotplug more about PageOffline()
   pages" and permits the removal of some virtio-mem hacks.
 
 - Barry Song's series "mm: clarify folio_add_new_anon_rmap() and
   __folio_add_anon_rmap()" is a cleanup to the anon folio handling in
   preparation for mTHP (multisize THP) swapin.
 
 - Kefeng Wang's series "mm: improve clear and copy user folio"
   implements more folio conversions, this time in the area of large folio
   userspace copying.
 
 - The series "Docs/mm/damon/maintaier-profile: document a mailing tool
   and community meetup series" tells people how to get better involved
   with other DAMON developers.  From SeongJae Park.
 
 - A large series ("kmsan: Enable on s390") from Ilya Leoshkevich does
   that.
 
 - David Hildenbrand sends along more cleanups, this time against the
   migration code.  The series is "mm/migrate: move NUMA hinting fault
   folio isolation + checks under PTL".
 
 - Jan Kara has found quite a lot of strangenesses and minor errors in
   the readahead code.  He addresses this in the series "mm: Fix various
   readahead quirks".
 
 - SeongJae Park's series "selftests/damon: test DAMOS tried regions and
   {min,max}_nr_regions" adds features and addresses errors in DAMON's self
   testing code.
 
 - Gavin Shan has found a userspace-triggerable WARN in the pagecache
   code.  The series "mm/filemap: Limit page cache size to that supported
   by xarray" addresses this.  The series is marked cc:stable.
 
 - Chengming Zhou's series "mm/ksm: cmp_and_merge_page() optimizations
   and cleanup" cleans up and slightly optimizes KSM.
 
 - Roman Gushchin has separated the memcg-v1 and memcg-v2 code - lots of
   code motion.  The series (which also makes the memcg-v1 code
   Kconfigurable) are
 
   "mm: memcg: separate legacy cgroup v1 code and put under config
   option" and
   "mm: memcg: put cgroup v1-specific memcg data under CONFIG_MEMCG_V1"
 
 - Dan Schatzberg's series "Add swappiness argument to memory.reclaim"
   adds an additional feature to this cgroup-v2 control file.
 
 - The series "Userspace controls soft-offline pages" from Jiaqi Yan
   permits userspace to stop the kernel's automatic treatment of excessive
   correctable memory errors.  In order to permit userspace to monitor and
   handle this situation.
 
 - Kefeng Wang's series "mm: migrate: support poison recover from migrate
   folio" teaches the kernel to appropriately handle migration from
   poisoned source folios rather than simply panicing.
 
 - SeongJae Park's series "Docs/damon: minor fixups and improvements"
   does those things.

Merge tag 'mm-stable-2024-07-21-14-50' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Pull MM updates from Andrew Morton:

 - In the series "mm: Avoid possible overflows in dirty throttling" Jan
   Kara addresses a couple of issues in the writeback throttling code.
   These fixes are also targetted at -stable kernels.

 - Ryusuke Konishi's series "nilfs2: fix potential issues related to
   reserved inodes" does that. This should actually be in the
   mm-nonmm-stable tree, along with the many other nilfs2 patches. My
   bad.

 - More folio conversions from Kefeng Wang in the series "mm: convert to
   folio_alloc_mpol()"

 - Kemeng Shi has sent some cleanups to the writeback code in the series
   "Add helper functions to remove repeated code and improve readability
   of cgroup writeback"

 - Kairui Song has made the swap code a little smaller and a little
   faster in the series "mm/swap: clean up and optimize swap cache
   index".

 - In the series "mm/memory: cleanly support zeropage in
   vm_insert_page*(), vm_map_pages*() and vmf_insert_mixed()" David
   Hildenbrand has reworked the rather sketchy handling of the use of
   the zeropage in MAP_SHARED mappings. I don't see any runtime effects
   here - more a cleanup/understandability/maintainablity thing.

 - Dev Jain has improved selftests/mm/va_high_addr_switch.c's handling
   of higher addresses, for aarch64. The (poorly named) series is
   "Restructure va_high_addr_switch".

 - The core TLB handling code gets some cleanups and possible slight
   optimizations in Bang Li's series "Add update_mmu_tlb_range() to
   simplify code".

 - Jane Chu has improved the handling of our
   fake-an-unrecoverable-memory-error testing feature MADV_HWPOISON in
   the series "Enhance soft hwpoison handling and injection".

 - Jeff Johnson has sent a billion patches everywhere to add
   MODULE_DESCRIPTION() to everything. Some landed in this pull.

 - In the series "mm: cleanup MIGRATE_SYNC_NO_COPY mode", Kefeng Wang
   has simplified migration's use of hardware-offload memory copying.

 - Yosry Ahmed performs more folio API conversions in his series "mm:
   zswap: trivial folio conversions".

 - In the series "large folios swap-in: handle refault cases first",
   Chuanhua Han inches us forward in the handling of large pages in the
   swap code. This is a cleanup and optimization, working toward the end
   objective of full support of large folio swapin/out.

 - In the series "mm,swap: cleanup VMA based swap readahead window
   calculation", Huang Ying has contributed some cleanups and a possible
   fixlet to his VMA based swap readahead code.

 - In the series "add mTHP support for anonymous shmem" Baolin Wang has
   taught anonymous shmem mappings to use multisize THP. By default this
   is a no-op - users must opt in vis sysfs controls. Dramatic
   improvements in pagefault latency are realized.

 - David Hildenbrand has some cleanups to our remaining use of
   page_mapcount() in the series "fs/proc: move page_mapcount() to
   fs/proc/internal.h".

 - David also has some highmem accounting cleanups in the series
   "mm/highmem: don't track highmem pages manually".

 - Build-time fixes and cleanups from John Hubbard in the series
   "cleanups, fixes, and progress towards avoiding "make headers"".

 - Cleanups and consolidation of the core pagemap handling from Barry
   Song in the series "mm: introduce pmd|pte_needs_soft_dirty_wp helpers
   and utilize them".

 - Lance Yang's series "Reclaim lazyfree THP without splitting" has
   reduced the latency of the reclaim of pmd-mapped THPs under fairly
   common circumstances. A 10x speedup is seen in a microbenchmark.

   It does this by punting to aother CPU but I guess that's a win unless
   all CPUs are pegged.

 - hugetlb_cgroup cleanups from Xiu Jianfeng in the series
   "mm/hugetlb_cgroup: rework on cftypes".

 - Miaohe Lin's series "Some cleanups for memory-failure" does just that
   thing.

 - Someone other than SeongJae has developed a DAMON feature in Honggyu
   Kim's series "DAMON based tiered memory management for CXL memory".
   This adds DAMON features which may be used to help determine the
   efficiency of our placement of CXL/PCIe attached DRAM.

 - DAMON user API centralization and simplificatio work in SeongJae
   Park's series "mm/damon: introduce DAMON parameters online commit
   function".

 - In the series "mm: page_type, zsmalloc and page_mapcount_reset()"
   David Hildenbrand does some maintenance work on zsmalloc - partially
   modernizing its use of pageframe fields.

 - Kefeng Wang provides more folio conversions in the series "mm: remove
   page_maybe_dma_pinned() and page_mkclean()".

 - More cleanup from David Hildenbrand, this time in the series
   "mm/memory_hotplug: use PageOffline() instead of PageReserved() for
   !ZONE_DEVICE". It "enlightens memory hotplug more about PageOffline()
   pages" and permits the removal of some virtio-mem hacks.

 - Barry Song's series "mm: clarify folio_add_new_anon_rmap() and
   __folio_add_anon_rmap()" is a cleanup to the anon folio handling in
   preparation for mTHP (multisize THP) swapin.

 - Kefeng Wang's series "mm: improve clear and copy user folio"
   implements more folio conversions, this time in the area of large
   folio userspace copying.

 - The series "Docs/mm/damon/maintaier-profile: document a mailing tool
   and community meetup series" tells people how to get better involved
   with other DAMON developers. From SeongJae Park.

 - A large series ("kmsan: Enable on s390") from Ilya Leoshkevich does
   that.

 - David Hildenbrand sends along more cleanups, this time against the
   migration code. The series is "mm/migrate: move NUMA hinting fault
   folio isolation + checks under PTL".

 - Jan Kara has found quite a lot of strangenesses and minor errors in
   the readahead code. He addresses this in the series "mm: Fix various
   readahead quirks".

 - SeongJae Park's series "selftests/damon: test DAMOS tried regions and
   {min,max}_nr_regions" adds features and addresses errors in DAMON's
   self testing code.

 - Gavin Shan has found a userspace-triggerable WARN in the pagecache
   code. The series "mm/filemap: Limit page cache size to that supported
   by xarray" addresses this. The series is marked cc:stable.

 - Chengming Zhou's series "mm/ksm: cmp_and_merge_page() optimizations
   and cleanup" cleans up and slightly optimizes KSM.

 - Roman Gushchin has separated the memcg-v1 and memcg-v2 code - lots of
   code motion. The series (which also makes the memcg-v1 code
   Kconfigurable) are "mm: memcg: separate legacy cgroup v1 code and put
   under config option" and "mm: memcg: put cgroup v1-specific memcg
   data under CONFIG_MEMCG_V1"

 - Dan Schatzberg's series "Add swappiness argument to memory.reclaim"
   adds an additional feature to this cgroup-v2 control file.

 - The series "Userspace controls soft-offline pages" from Jiaqi Yan
   permits userspace to stop the kernel's automatic treatment of
   excessive correctable memory errors. In order to permit userspace to
   monitor and handle this situation.

 - Kefeng Wang's series "mm: migrate: support poison recover from
   migrate folio" teaches the kernel to appropriately handle migration
   from poisoned source folios rather than simply panicing.

 - SeongJae Park's series "Docs/damon: minor fixups and improvements"
   does those things.

 - In the series "mm/zsmalloc: change back to per-size_class lock"
   Chengming Zhou improves zsmalloc's scalability and memory
   utilization.

 - Vivek Kasireddy's series "mm/gup: Introduce memfd_pin_folios() for
   pinning memfd folios" makes the GUP code use FOLL_PIN rather than
   bare refcount increments. So these paes can first be moved aside if
   they reside in the movable zone or a CMA block.

 - Andrii Nakryiko has added a binary ioctl()-based API to
   /proc/pid/maps for much faster reading of vma information. The series
   is "query VMAs from /proc/<pid>/maps".

 - In the series "mm: introduce per-order mTHP split counters" Lance
   Yang improves the kernel's presentation of developer information
   related to multisize THP splitting.

 - Michael Ellerman has developed the series "Reimplement huge pages

acc5965b9f Char/Misc and other driver changes for 6.11-rc1 
Here is the "big" set of char/misc and other driver subsystem changes
 for 6.11-rc1.  Nothing major in here, just loads of new drivers and
 updates.  Included in here are:
   - IIO api updates and new drivers added
   - wait_interruptable_timeout() api cleanups for some drivers
   - MODULE_DESCRIPTION() additions for loads of drivers
   - parport out-of-bounds fix
   - interconnect driver updates and additions

   - w1 driver fixes
   - binder speedups and fixes
   - eeprom driver updates
   - coresight driver updates
   - counter driver update
   - new misc driver additions
   - other minor api updates
 
 All of these, EXCEPT for the final Kconfig build fix for 32bit systems,
 have been in linux-next for a while with no reported issues.  The
 Kconfig fixup went in 29 hours ago, so might have missed the latest
 linux-next, but was acked by everyone involved.

Linus Torvalds
bf3aa9de7b New code for 6.11: 
* Enable FITRIM on the realtime device.
   * Introduce byte-based grant head log reservation tracking instead of
     physical log location tracking.
     This allows grant head to track a full 64 bit bytes space and hence
     overcome the limit of 4GB indexing that has been present until now.
   * Fixes
     - xfs_flush_unmap_range() and xfs_prepare_shift() should consider RT extents
       in the flush unmap range.
     - Implement bounds check when traversing log operations during log replay.
     - Prevent out of bounds access when traversing a directory data block.
     - Prevent incorrect ENOSPC when concurrently performing file creation and
       file writes.
     - Fix rtalloc rotoring when delalloc is in use
   * Cleanups
     - Clean up I/O path inode locking helpers and the page fault handler.
     - xfs: hoist inode operations to libxfs in anticipation of the metadata
       inode directory feature, which maintains a directory tree of metadata
       inodes. This will be necessary for further enhancements to the realtime
       feature, subvolume support.
     - Clean up some warts in the extent freeing log intent code.
     - Clean up the refcount and rmap intent code before adding support for
       realtime devices.
     - Provide the correct email address for sysfs ABI documentation.

51835949dd Networking changes for 6.11. Not much excitement - a handful of large 
patchsets (devmem among them) did not make it in time.
 
 Core & protocols
 ----------------
 
  - Use local_lock in addition to local_bh_disable() to protect per-CPU
    resources in networking, a step closer for local_bh_disable() not
    to act as a big lock on PREEMPT_RT.
 
  - Use flex array for netdevice priv area, ensure its cache alignment.
 
  - Add a sysctl knob to allow user to specify a default rto_min at socket
    init time. Bit of a big hammer but multiple companies were
    independently carrying such patch downstream so clearly it's useful.
 
  - Support scheduling transmission of packets based on CLOCK_TAI.
 
  - Un-pin TCP TIMEWAIT timer to avoid it firing on CPUs later cordoned off
    using cpusets.
 
  - Support multiple L2TPv3 UDP tunnels using the same 5-tuple address.
 
  - Allow configuration of multipath hash seed, to both allow synchronizing
    hashing of two routers, and preventing partial accidental sync.
 
  - Improve TCP compliance with RFC 9293 for simultaneous connect().
 
  - Support sending NAT keepalives in IPsec ESP in UDP states. Userspace
    IKE daemon had to do this before, but the kernel can better keep
    track of it.
 
  - Support sending supervision HSR frames with MAC addresses stored in
    ProxyNodeTable when RedBox (i.e. HSR-SAN) is enabled.
 
  - Introduce IPPROTO_SMC for selecting SMC when socket is created.
 
  - Allow UDP GSO transmit from devices with no checksum offload.
 
  - openvswitch: add packet sampling via psample, separating the sampled
    traffic from "upcall" packets sent to user space for forwarding.
 
  - nf_tables: shrink memory consumption for transaction objects.
 
 Things we sprinkled into general kernel code
 --------------------------------------------
 
  - Power Sequencing subsystem (used by Qualcomm Bluetooth driver
    for QCA6390).
 
  - Add IRQ information in sysfs for auxiliary bus.
 
  - Introduce guard definition for local_lock.
 
  - Add aligned flavor of __cacheline_group_{begin, end}() markings for
    grouping fields in structures.
 
 BPF
 ---
 
  - Notify user space (via epoll) when a struct_ops object is getting
    detached/unregistered.
 
  - Add new kfuncs for a generic, open-coded bits iterator.
 
  - Enable BPF programs to declare arrays of kptr, bpf_rb_root, and
    bpf_list_head.
 
  - Support resilient split BTF which cuts down on duplication and makes
    BTF as compact as possible WRT BTF from modules.
 
  - Add support for dumping kfunc prototypes from BTF which enables both
    detecting as well as dumping compilable prototypes for kfuncs.
 
  - riscv64 BPF JIT improvements in particular to add 12-argument support
    for BPF trampolines and to utilize bpf_prog_pack for the latter.
 
  - Add the capability to offload the netfilter flowtable in XDP layer
    through kfuncs.
 
 Driver API
 ----------
 
  - Allow users to configure IRQ tresholds between which automatic IRQ
    moderation can choose.
 
  - Expand Power Sourcing (PoE) status with power, class and failure
    reason. Support setting power limits.
 
  - Track additional RSS contexts in the core, make sure configuration
    changes don't break them.
 
  - Support IPsec crypto offload for IPv6 ESP and IPv4 UDP-encapsulated ESP
    data paths.
 
  - Support updating firmware on SFP modules.
 
 Tests and tooling
 -----------------
 
  - mptcp: use net/lib.sh to manage netns.
 
  - TCP-AO and TCP-MD5: replace debug prints used by tests with
    tracepoints.
 
  - openvswitch: make test self-contained (don't depend on OvS CLI tools).

cc0f7c3f97 soc: driver updates for 6.11 
The updates to the mediatek, allwinner, ti, tegra, microchip, stm32,
 samsung, imx, zynq and amlogic platoforms are farily small maintenance
 changes, either addressing minor mistakes or enabling additional hardware.
 
 The qualcomm platform changes add a number of features and are larger
 than the other ones combined, introducing the use of linux/cleanup.h
 across several drivers, adding support for Snapdragon X1E and other
 SoCs in platform drivers, a new "protection domain mapper" driver, and a
 "shared memory bridge" driver.
 
 The cznic "turris omnia" router based on Marvell Armada gets a platform
 driver that talks to the board specific microcontroller.
 
 The reset and cache subsystems get a few minor updates to SoC specific
 drivers, while the ff-a, scmi and optee firmware drivers get some
 code refactoring and new features.

a808878308 driver core: auxiliary bus: show auxiliary device IRQs 
PCI subfunctions (SF) are anchored on the auxiliary bus. PCI physical
and virtual functions are anchored on the PCI bus. The irq information
of each such function is visible to users via sysfs directory "msi_irqs"
containing files for each irq entry. However, for PCI SFs such
information is unavailable. Due to this users have no visibility on IRQs
used by the SFs.
Secondly, an SF can be multi function device supporting rdma, netdevice
and more. Without irq information at the bus level, the user is unable
to view or use the affinity of the SF IRQs.

Hence to match to the equivalent PCI PFs and VFs, add "irqs" directory,
for supporting auxiliary devices, containing file for each irq entry.

For example:
$ ls /sys/bus/auxiliary/devices/mlx5_core.sf.1/irqs/
