Pull sh updates from John Paul Adrian Glaubitz:
"Fixes and improvements for various boards as well as the generic sh
kernel:
- help the mach-x3proto and ecovec24 boards get rid off the use of
the old platform data API in the kernel. For the former board,
software nodes are being used for gpio-keys now while for the
latter board, static device properties are used to describe the
touchscreen (Dmitry Torokhov)
- a build fix when CONFIG_BUILTIN_DTB is enabled, and fix an issue
with __get_user_u64() and __put_user_u64() using wrong memory
operands which could cause the kernel build to fail with "invalid
'asm'" or an internal compiler error in GCC's change_address_1
(Florian Fuchs)
- update various default configuration files of several boards to
replace the removed CONFIG_USB_GADGET_M66592 with the new
CONFIG_USB_M66592 Kconfig option (Pengpeng Hou)
- fix two issues with the SH-7785LCR evaluation board: fix a kernel
memory leak which occurred as a result of the prio and sense lists
being sorted too early in register_intc_controller(), and fix the
the registration of the PCA9564 controller so that the RTC works
properly again (Karl Mehltretter)
- fix missing cookies when calling free_irq() in the maple bus driver
which ensures that IRQ handlers can be properly unregistered and
the kernel does not emit a WARN message (Runyu Xiao)
- select BINFMT_FLAT_NO_DATA_START_OFFSET for !MMU configurations
such that there is no gap at the end of text and init runs which
causes the GOT register to point below the real GOT, so every GOT
load reads the neighbouring slot and gets a wrong pointer (Waldemar
Brodkorb)"

Pull EFI updates from Ard Biesheuvel:
- Set the LoaderDevicePartUUID EFI variable from the stub to help
systemd discover the file system layout when booting straight into
Linux without GRUB or systemd-boot (Vincent Mailhol)
- Some GUID deduplication work from Vincent
- Remove pointless UTF16->UTF8 and vice versa conversions from the stub
- Some kmap() -> kmap_local_page() conversions in the capsule loader
- Add a runtime control to en/disable EFI runtime services so that
PREEMPT_RT systems can enable them as needed
- Add a 'nostatfs' mount option to efivarfs so that the cost of
querying the EFI variable store (which is already rate limited) can
be avoided entirely on systems where it is disproportionately costly
- Rework the EFI libstub Makefile to align x86 with other
architectures, and inherit/adapt the global CFLAGS variable rather
than reconstruct it from scratch
- Constify attributes of statically allocated sysfs nodes
- Avoid register x18 when building the arm64 EFI stub, in order to
comply with the UEFI spec, and to permit it to execute in a context
where x18 is special
- Preserve the physical addresses of all EFI config tables that may be
of interest to an incoming kexec kernel
- Add some LKDTM tests for EFI runtime crashes where the faulting
address is inside a EFI memory region

Pull MTD updates from Miquel Raynal:
"Core MTD:
- Fixes to the virt-concat driver
- Added INT0800 firmware-flash map driver
- mtdblock: prevent reclaim I/O during request processing
- cfi_cmdset_0002: cap the write-buffer chunk at 256 bytes on an x8 device
Raw NAND:
- Clean up the Qualcomm controller driver again
- Improve / create Arasan and IBM
- Reflect that ESMT and GigaDevice share ID 0xc8, and disable broken
timings feature on GD9FU2G8F3A
- Drop platform data support from the lpc32xx drivers
SPI NAND:
- Heyangtek uses two bytes for the BBM like every other device
- Winbond: Add support for W25N04LW and W25N08LW
- Support for ISSI SPI NAND flashes
SPI NOR:
- Support for new Macronix and (lots of) Winbond flash devices
- Rewrite the status register handling. There were many small helper
functions to enable quad I/O mode in many different ways. That's
now consolidated in one generic function.
- Rework the SFPD handling. It used to be only parsed for flashes
present in the in-kernel database which had any of the multi-I/O
bit set - or with the addition of generic flash driver for any
unknown flashes. This left a gap where SFDP wasn't handled and it
turns out newer flashes (with SFDP support) will reused IDs of just
these old flashed. With the rework, SFDP is tried to be parsed for
any flashes and will amend the information which is already present
in the in-kernel database.
- Increase SFDP size limit to 16KiB. There are flashes which have
some larger gaps between tables and thus exceeds the former 4KiB
limit.
- Flash fixups are getting more and more common. Due to this, the
fixups are now a separate list (per manufacturer) instead of being
attached to a specific flash. A new .match() callback makes them
more flexible, when one is applied.
- Support 1-1-8 and 1-8-8 modes with larger flashes which need 4byte
addresses
Then there is the load of API updates and misc AI fixes"

Pull input updates from Dmitry Torokhov:
- Updates to input core to reject parent device overrides on managed
input devices so devres lifetime management is not split across
different devices, along with fixes for da7280, drv2665, drv2667, and
tps6507x-ts that were reparenting managed input devices, and removal
of redundant parent assignments across multiple drivers
- A fix in input core to always accept EV_SYN events in input_event()

are properly flushed by input_sync()
- A fix in matrix-keymap helper to reject keycodes above KEY_MAX and
prevent out-of-bounds bitmap writes
- Fixes and cleanups for HP GSC PS/2 (gscps2) serio driver to resolve
race conditions in port list management, ring buffer access, and
interrupt handling, return IRQ_NONE for unhandled shared interrupts,
and drop busy-waiting on transmit

limits, and stop polling and clear the callback on close
- Updates to maplemouse driver to stop polling and clear the callback
on close and drop redundant driver data cleanup
- Fixes for matrix_keypad driver reverting forced switching of row
GPIOs to input mode that broke row interrupts on platforms with
separate GPIO and interrupt pinmux functions, and propagating the
actual error code from matrix_keypad_build_keymap()
- A fix for st-keyscan driver to keep the interrupt disabled while the
peripheral clock is gated off to prevent bus faults, along with probe
error handling improvements
- A fix for mms114 touchscreen driver to disable interrupts before
synthesizing touch release events during suspend so concurrent
interrupts do not leave stuck active touch slots

Pull firewire updates from Takashi Sakamoto:
- Guarantee asynchronous packet and transaction callbacks in process
context
Both the 1394 OHCI driver and the core transaction layer have been
changed to guarantee that asynchronous packet and transaction
callbacks are invoked in process context. In v6.17, the execution
context depended on the transaction destination: callbacks for
transactions destined for remote nodes were invoked from a workqueue,
whereas callbacks for transactions destined for the local node or
terminated due to internal errors were invoked in the transaction
initiator's context.
All such callbacks are now guaranteed to execute in process context,
eliminating the need to account for different execution contexts when
implementing callback functions.
- Fill kerneldoc for transaction layer
The above change guarantees a consistent execution context for packet
and transaction callbacks, making it possible to document their
execution context in kerneldoc.
- Enable compiler-based context analysis for the transaction layer
The core transaction layer is sufficiently complex that
compiler-based context analysis can help detect invalid call paths.
- Fix a reference count leak in the cdev layer
A reference count leak was reported when a user space application
delegated isochronous resource management. This issue has now been
fixed.
- Add KUnit tests for the configuration ROM parser and generator
In recent years, questions have been raised about how the
configuration ROM parser and generator handle boundary conditions and
edge cases. KUnit tests have been added to verify their behavior in
these situations. KUNIT_STATIC_STUB_REDIRECT is used to stub the
transaction responder so that it returns the configuration ROM
contents.
- Misc fixes for kerneldoc and nosy-dump application

Pull SCSI updates from James Bottomley:
"Small number of driver updates (mpi3mr, ufs, scsi_debug).
By far the biggest core change (at 4000+ lines) is the sense code
rework to make our sense handling follow the 16 bit defines in the
SCSI standard rather than our split ASC and ASCQ handling which ends
up being confusing and difficult to grep.
The changes should all be functionally equivalent and so far the bots

September with one reported issue fixed.

Pull io_uring updates from Jens Axboe:
"The bulk of this is a big robustness pass over cancelation, io-wq,
timeouts, and poll. Outside of that:

poll, and wait paths. Fixes for lost wakeups and lost cancels as
io-wq arms poll/timeouts, work stranding on worker exit, CQE32
resize handling, napi entry timeouts, and a pile of smaller
correctness issues across the board
- Rework of how io-wq posts completions, posting from the last
request reference and dropping the request file before the
completion, and running ring release cancelations synchronously -
canceling and waiting for all in-flight requests and dropping
registered files and buffers at release time
- Don't charge the SQ/CQ rings or provided buffer rings to
RLIMIT_MEMLOCK, which the region API conversion had started doing
- Split io_uring_cmd_set_res() out from io_uring_cmd_done() so a
command can set the result from its ->end_io() handler, used by
nvme
- CQE32 ring fixes for the free entry check, aux CQE big_cqe zeroing,
and the dummy skip CQE
- Timeout fixes for sequence handling and multishot updates
- net fixes for MSG_TRUNC buffer overconsumption and keeping recv

git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci
Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Set supported_speeds in set_pcie_port_type() so sparc64 and
powerpc, which call it via of_create_pci_dev() instead of the usual
pci_setup_device(), correctly set the supported PCIe link speeds
(Stian Halseth)
- When pcie_set_mps() changes MPS, update the value in the saved
state so a subsequent restore doesn't restore an invalid value
(Niklas Cassel)
- Skip Target Speed quirk on clamped ports with no link (Maciej W.
Rozycki)
Driver binding:
- Assume control of portdrv-related features only when portdrv is
enabled, since we can't use them without portdrv (Kuppuswamy
Sathyanarayanan)
- Centralize feature ownership checking so code only needs to check
'host->native_X' and doesn't need to also check 'pcie_ports_native'
(Kuppuswamy Sathyanarayanan)
Error handling:
- Fix leaks when ACPI APEI/GHES error events overflow the kfifo or
mention a device that no longer exists (Priyank Rathod)
- Fix aer_process_err_devices() leak when a device is recorded as an
error source purely by being mentioned in the Root Port Error
Source and the device is inaccessible or logged only masked errors
(Priyank Rathod)
ASPM:
- Disable ASPM when drivers request that, even if the OS doesn't own
ASPM; otherwise drivers do it on their own, which is worse (Ilpo
Järvinen)
Power management:
- Align hibernate poweroff flow with suspend flow for bridges so they
can be powered down at hibernate as they are for suspend (Mario
Limonciello)
- Restore BARs after powering up during enumeration to fix a
regression on devices that don't preserve state in D3hot (Keng-Yu
Lin)
- Avoid D3 on PLX PEX 8532/8533/8548 downstream ports, where putting
them in D3hot takes down the whole switch (Imre Kaloz)
Power control:
- Add GPIO driver for Toshiba TC9563 embedded GPIO controller (Alex
Elder)
- Add DT documentation and pwrctrl driver support for TC9563 embedded
GPIO controller (Lorenzo Bianconi)
- Switch the tc9563 per-port reset to use the GPIO descriptor API
instead of direct regmap accesses (Lorenzo Bianconi)
- Only destroy devices created by pwrctrl core, so that when removing
a PCIe controller driver that uses pwrctrl, we don't remove devices
populated by another mechanism (Shawn Lin)
- Power off child devices on power-on failure (Lorenzo Bianconi)
PCIe native device hotplug:
- Make the 'pciehp_poll_mode' parameter read-only to prevent changes
via sysfs, which can cause errors when unbinding (Runyu Xiao)
Virtualization:
- Read SR-IOV VF Revision ID and Subsystem ID from VF instead of
assuming they're the same as VF 0; they may differ (Logan Odell)
- Add ACS quirk for Pericom PI7C9X2G304 switches (Hans de Goede)
Peer-to-peer DMA:
- Add Zhaoxin KX-6000, KH-40000, KX-6000G, KX-7000, and KH-50000 host
bridges to allowlist (LeoLiu-oc)
- Add Alibaba T-HEAD Yitian 710 host bridge to allowlist (Feng Tang)
- Add Intel Haswell client host bridge to allowlist (Scott Lee)
- Intel Xeon E3/E5/E7 0x6f00 host bridge to allowlist (kai zhang)
- Fix handling of errors in pci_p2pdma_add_resource() to avoid (a)
unmapping a BAR if registering another fails and (b) use after free
of p2p_pgmap (Leon Romanovsky)
- Wait for RCU readers before freeing state to avoid use-after-free
of pdev->p2pdma (Leon Romanovsky)
- Restrict pci_p2pmem_find_many() to providers backed by a pool (Leon
Romanovsky)
- Safely terminate ACS redirect lists to avoid out-of-bounds access
to the buffer (Leon Romanovsky)
- Silence 'Host bridge not in P2PDMA whitelist' warnings unless
caller, e.g., pci_p2pmem_find_many(), requests 'verbose' (Leon
Romanovsky)
Sysfs:
- Return -ENODEV or -EIO sysfs 'label' or 'acpi_index' attributes
when Device Name _DSM fails, not -1, which is interpreted as -EPERM
(Krzysztof Wilczyński)
- Return valid sysfs 'acpi_index' attribute even if the Device Name
_DSM returned an invalid 'label' (Krzysztof Wilczyński)
- Expose sysfs 'acpi_index' and 'label' based on whether the Device
Name _DSM returns valid data, not merely whether the _DSM is
implemented (Krzysztof Wilczyński)
- Avoid out-of-bounds reads of the label returned by the Device Name
_DSM, which is in UTF-16 characters, not bytes (Krzysztof
Wilczyński)
- Reject unaligned resource I/O port accesses, which can oops on
arm64 (Deepanshu Kartikey)
Endpoint framework:
- Pass the correct physical and virtual endpoint function numbers
when setting translation of inbound memory windows (Koichiro Den)
- Make embedded doorbell IRQ non-shared, since currently only the
first EPF can allocate doorbells (Koichiro Den)
- MSI doorbells currently target the first EPF attached to an EPC;
let other EPFs try the embedded doorbell instead of failing when
they can't use the MSI doorbell (Koichiro Den)
- Serialize scan of vNTB virtual PCI bus with other PCI topology
changes (Koichiro Den)
- Manage vNTB lifetimes to avoid leaking virtual devices and buses
and allow removal (Koichiro Den)
- Track vNTB link state from both sides so both see the same
effective link state (Koichiro Den)
- Configure vNTB MSI-X when supported to avoid IOMMU faults and
failure to deliver doorbell interrupts on RC (Koichiro Den)
APM X-Gene PCIe controller driver:
- Use devm for clocks so they're automatically disabled, unprepared,
and released if errors happen during probe (Yuho Choi)
ASPEED PCIe controller driver:
- Fix clk and PHY leaks in aspeed_pcie_port_init() error paths (Liu
Zhenlong)
Broadcom iProc PCIe controller driver:
- Expose devm_pci_alloc_host_bridge_release() so drivers can share a
devm release function even if they don't need the device tree
parsing done by devm_pci_alloc_host_bridge() (Bjorn Helgaas)
- Request only the memory window from BCMA Enumeration ROM and warn
if it doesn't match the one in DT, which fixes an iproc-bcma probe
failure (Semih Baskan)
Broadcom STB PCIe controller driver:
- Replace bool properties for each SoC configuration with a u32
bitvector and a BFLAG() helper (Jim Quinlan)
- Use a similar BQUIRK() helper to test various SoC quirks (Jim
Quinlan)
Cadence PCIe controller driver:
- Remove device links to PHY, which are redundant because the PHY
core itself adds them (Vladimir Oltean)
- Return error (not success) from cdns_plat_pcie_probe() if
pm_runtime_get_sync() or cdns_pcie_ep_setup() failed (Vladimir
Oltean)
- Correct the driver data pointer usage; previously .probe() stored
'struct cdns_plat_pcie *', but .shutdown() used the pointer as
'struct cdns_pcie *', resulting in accessing garbage (Linmao Li)
ESWIN PCIe controller driver:
- Publish the platform driver MODULE_DEVICE_TABLE so the driver can
be autoloaded when built as a module (Pengpeng Hou)
Freescale i.MX6 PCIe controller driver:
- Fix resource and pwrctrl device leaks .probe() (Zhijian Han)
- Improve i.MX95 Gen3 link stability by changing MPLLB_BANDWIDTH from
default 120 to 140 (Richard Zhu)
- Use dev_err_probe() in host init error path to silence
-EPROBE_DEFER messages (Alexander Stein)
- Avoid dereferencing NULL clock names when 'clocks' includes more
phandles than 'clock-names' has names (Rudi Heitbaum)
- Add suspend_poweroff flag so platforms like i.MX that power off RC
controllers during suspend can enter L2 so endpoints can get
PME_Turn_Off notifications before power loss (Richard Zhu)
Freescale Layerscape PCIe controller driver:
- Enable PROBE_PREFER_ASYNCHRONOUS to reduce probe time of the four
controllers on LX2160A (Vincent Jardin)
Intel VMD host bridge driver:
- Flush DMA writes before handling MSI on Meteor Lake: MSI may arrive
before write has completed, resulting in an nvme 30 second stall
before a QID timeout and possibly other similar problems (Rickey
Bartlett)
- Flush DMA writes before handling MSI on Arrow Lake (Vladimir
Nedoshivin)
Marvell Aardvark PCIe controller driver:
- Disable PHY on probe failures (Myeonghun Pak)
Marvell MVEBU PCIe controller driver:
- Refcount child OF nodes during .probe() to make a concurrent OF
overlay removal safe (Krzysztof Kozlowski)
MediaTek PCIe controller driver:
- Find INTx DT property by 'interrupt-controller' name instead of
assuming it's the first child node (Zhengping Zhang)
MediaTek PCIe Gen3 controller driver:
- Fix a 64-bit type truncation in mtk_pcie_set_trans_table() to avoid
issues with windows above or larger than 4GB (Sreeraj S Kurup)
NVIDIA Tegra264 PCIe controller driver:
- Fix the Link Capabilities offset so we read the correct register
(Bjorn Helgaas)
Qualcomm PCIe controller driver:
- Only collect reset GPIOs from PCI bridge DT nodes to avoid stealing
resets used by downstream devices like USB controllers (Christopher
Obbard)
- Block accesses to downstream devices on link down to reduce a storm
of Completion Timeout AER interrupts (Qiang Yu)
- Skip system suspend/resume for firmware-managed PCIe, where
firmware manages clocks, regulators, resets, etc (Mrinmay Sarkar)
- Honor IOMMU provider's #iommu-cells in qcom_pcie_config_sid_1_9_0()
(Manivannan Sadhasivam)
- Deinitialize endpoint on remove (Guangshuo Li)
- Treat Root Port error recovery as successful even if link doesn't
come up after reset because the device was hot-unplugged (Konrad
Dybcio)
- Skip unnecessary iMSI-RX initialization if DT 'msi-map' is present,
indicating an external MSI controller (Ayiluri Naga Rashmi)
Renesas R-Car PCIe controller driver:
- Limit Max_Read_Request_Size to 256 to avoid hardware erratum (Marek
Vasut)
- Support PERST# via reset subsystem as well as the existing GPIO
support to prepare for R-Car Gen5 SoCs (Marek Vasut)
- Add DT and driver support for the R-Car Gen 5 X5H (R8A78000) PCIe
Gen 4 core (Marek Vasut)
- Add Application/Local register reset DT description and driver
support for both host and endpoint mode (Marek Vasut)
- Add PM ops so controller works after suspend/resume (Marek Vasut)
Renesas RZ/G3S PCIe controller driver:
- Disable refclk on probe failure (Lad Prabhakar)

Prabhakar)
- Add RZ/G3L (R9A08G046) DT and driver support (Biju Das)
Rockchip PCIe controller driver:
- Limit host and endpoint controllers to 2.5 GT/s since 5.0 GT/s is
unsafe per Rockchip (Geraldo Nascimento)
Synopsys DesignWare PCIe controller driver:
- Set DMA_BYPASS bit in outbound IATU CTRL2 register to avoid data
corruption if the iATU translates DMA engine transactions (Sumit
Kumar)
- Use FIELD_PREP() to remove need for *_SHIFT definitions (Hans
Zhang)
TI DRA7xx PCIe controller driver:
- Remove device links to PHY, which are redundant because the PHY
core itself adds them (Vladimir Oltean)
- Fix optional clock leak when .probe() fails by using
devm_clk_get_optional_enabled() (Felix Gu)
TI Keystone PCIe controller driver:
- Remove device links to PHY, which are redundant because the PHY
core itself adds them (Vladimir Oltean)
UltraRISC PCIe controller driver:
- Allow DWC drivers to skip outbound iATU setup if they don't need
translation between CPU and PCI addresses (Xincheng Zhang)
- Skip MEM outbound iATU setup on DP1000 (Xincheng Zhang)

Pull VFIO updates from Alex Williamson:
- Fix missing selftest <libgen.h> include for basename() to support
non-glibc builds (Hisam Mehboob)
- Add vfio selftest documentation covering the libvfio helper library
and guidance for developers to aid in adding and understanding the
framework (David Matlack)
- Fix vfio cdev open path to prevent a second open from clobbering the
vf_token or clearing the KVM reference. Add a selftest to avoid
future recurrences (Alex Williamson)
- Extend vfio selftest mix_and_match timeouts, in particular to account
for systems where generated faults can induce heavy SMM load,
delaying internal timeouts. Also extend timeout for execution via
runner to account for various tests exceeding default 45s timeout
(Alex Williamson)
- Add tracking for non-reserved mappings into a vfio_dma object in
order to optimize the tear-down paths where per-page tests can be
entirely skipped. This resolves a soft lockup for large memory GPUs
(Samuel Crossley)
- Add vfio selftest driver for mlx5, providing another target for
exercising DMA and interrupts against a physical device (Jason
Gunthorpe)
- Hardening against read-only region promotion, preserving vm_pgoff for
unmap_mapping_range(), and reject non-shared MMIO mmaps as necessary
through vfio-platform, vfio-fsl-mc, and vfio-cdx. These prevent
future issues, though none are currently reachable (Abdifatah Suruur)
- Fix 8-byte ioeventfd support, removing a static error test that was
erroneously left in place when generalizing 8-byte io accesses (Li
RongQing)
- Fix missed RCU drain on module exit (Jiale Yao)
- Fix off-by-one boundary check in migration support within the mlx5
vfio-pci variant driver (Seongjun Hong)
- Remove drvdata usage convention across vfio-pci-core, allowing
variant drivers to freely create their own conventions and enabling a
future Rust-based variant driver. A DRM topic branch is also merged
in support of this effort, modifying the vga arbiter API to more
cleanly remove the drvdata dependency (Simon Song)
- Fix hisi_acc vfio-pci variant driver to avoid NULL pointer accesses
when bound to unsupported devices and also disabling migration
support when running on 64K host page size due to BAR mapping
constraints (Longfang Liu)
- Add device IDs for Crescent Island and Nova Lake devices to the Xe
vfio-pci variant driver (Satyanarayana K V P)
- Fix fallback mode in nvgrace-gpu variant driver to use symmetric open
and close handlers to avoid reported use-after-free issue. Remove the
resulting unnecessary test in the now single-purpose open function

Pull KVM updates from Paolo Bonzini:
"ARM:
- pKVM state isolation: years after pKVM started being enabled
upstream, we finally get the basics in the form of state isolation.
The vcpu state is now off-limit for the host for protected VMs
- pKVM also grows a hypervisor-private memory allocator, allowing it
to deal with sub-page allocation, much like everywhere else
- pKVM also lands a trace_printk() equivalent, which hopefully will
make debugging a bit easier
- First shot at annotating portions of the KVM/arm64 code to be
extracted and built on s390. The real fun is yet to come
- Allow pre-faulting of stage-2 canonical mappings from userspace,
joining x86 and s390 in implementing this feature
- Add a reverse mapping infrastructure for shadow stage-2,
significantly improving performance when MMU notifiers kick in, and
avoiding full unmap of all shadow tables for this VM
- Next step of GICv5 enablement, adding support for the IRS block,
and providing both SPI and LPI support. This is the first point
where KVM/arm64 can support an SMP GICv5 guest
- As a preliminary to eventually enabling CCA, add a bunch of
infrastructure to KVM/arm64, splitting some of the basic operations
into individual backends (normal VM, normal pKVM VM, protected pKVM
VM). This allows CCA to later slot in without polluting the rest of
KVM with its firmware-driven nonsense
- Make ID registers immutable from the point where a vcpu is able to
run, even if it fails to run. This prevents KVM from sampling
untrusted values
- Restore some type checking to the EL2 object. KVM/arm64 originally
had some strong type checking between the kernel and the EL2
object, but lost it along the way when the private hypercall
interface was (somewhat pointlessly) converted to SMCCC. Type
checking is back, syscall style, and with added sparse goodies
- Expand the FFA support to FFA_NOTIFICATION_*, and add some
sanitisation of the protocol that pKVM relays to the "trusted"
runtime
- Make GICv3 RD assignment more robust to userspace nonsense
- Convert the remaining MMU fault handler backends to
kvm_s2_fault_vma_info and co., fixing a number of bugs in the
process
- Fix the SError/SEA selftests to be both more robust and less
braindead
- Fix a smattering of documentation bugs, some of them as a result of
our AI friends spitting out credible assertions based on
non-existing symbols
- The usual collection of low impact bug fixes (SMCCC, timers, PMU)
Loongarch:
- Add separate vmid support
- Simplify MSI interrupt injection
- Add crash hypercall support
- Allow to set pv_feature until vCPU run
- Enable HW page table walk automatically in selftests
s390:
- rework page allocation for secure guest variable storage
- Selftests and documentation improvements
- Replace get_zeroed_page with kzalloc
- Fix corner cases of floating interrupt injection
- Initial arm64 on s390 support
x86:
- Clean up the handling of vcpu->arch.xen.long_mode to be consistent
and correctly handle 32-bit/64-bit alignment, and various other bug
fixes have accumulated over the months since v1
- Grab KVM's SRCU "lock" in kvm_zap_gfn_range() to fix a recurring
bug where callers fail to do so
- Fix a variety of issues in the pre-fault code that are mostly
benign in the current code base, but will show up in big ways
if/when the pre-faulting logic is used to implementing
prefetch-on-fault for the TDP MMU
- For PREEMPT_RT=y kernels, drop the rmaps' individual bit-spinlock
and just walk the rmaps' with mmu_lock taken. On the write side
(which always uses mmu_lock), the bit-spinlock was assuming that
preemption was disabled, but that is *not* true when rwlocks become
sleepable
- Prepare a memory_fault exit (paired with -EFAULT) when KVM hits an
error PFN, e.g. so that userspace can resolve transient issues
instead of killing the guest. Convert a variety of WARN()+EFAULT
paths into KVM_BUG_ON()+EIO so that KVM can hard commit to filling
memory_fault on -EFAULTs that occur in the page fault path
- Fix a NX hugepage un-accounting bug where KVM would always uncharge
the shadow MMU, even when handling TDP MMU pages
- Mask off the address space ID when checking for illegal usage of
kvm_set_internal_memslot() to prevent false negatives on the sanity
check
- Explicitly zero reserved flags when delivering a SynIC message to
avoid leaking a byte of stack information to the guest
- Rework TDX's handling of the canonical MMU root level to not rely
on userspace to fill CPUID correctly, as doing so lets userspace
trivially trigger a KVM_BUG_ON()
- Reject KVM_SET_NESTED_STATE if userspace "restores" L1 with
EFER.LMA=1 && EFER.LME=0, which confuses KVM into trying to
configure an 64-bit MMU without PAE
- Ignore EFER.LMA (clear it from KVM's cached save state) if
EFER.LME=0 when preparing L2 state, to fix another way to confuse
KVM's MMU (and because real hardware also ignores EFER.LMA)
- Improve KVM's sanity checks for a misconfigured MMU to (hopefully)
detect all of the ways KVM can botch EFER.LMA vs. CR4.PAE
- Remove the "full" out-param from kvm_x86_ops.flush_tlb_gva() as the
param is only used to avoid what effectively amounts to a single
memory write
- Fix a mostly-benign bug where KVM can write through a guest's
read-only mapping due to not checking the error code when
expediting emulated MMIO page faults
- Honor the guest's view of the "EFER.LMSLE must be zero" defeature
so that userspace can provide migration compatibility between Rome
and Milan+
- Pend a KVM_REQ_EVENT request when an exception is morphed into a
nested VM-Exit, otherwise KVM can fail to actually deliver the
nested VM-Exit, e.g. when injecting a page fault
- Add support for PML on SVM
- Add support for virtualizing Bus Lock Detect on SVM, and fix a
number of DR6 bugs and warts along the way
- Fix a variety of warts in KVM's handling of guest TSC, kvmclock,
and timekeeping in general, as a (big) first step towards
addressing several longstanding problems with the kvmclock
implementation. Most notably, fix a precision issue where
get_kvmclock_ns() computed the clock from the *host* TSC without
applying guest TSC scaling, causing systemic drift from the values
the guest computes from its own TSC
- Rip out KVM's shadow timekeeping structures, now that ktime
snapshots are powerful enough to replace it
- Misc fixes and cleanups
x86 (AMD):
- Fix a benign-in-practice bug where KVM unintentionally sets a
non-zero error code when delivering exceptions to SEV-ES+ guests
- Force a new ASID in both VMCBs on pCPU migration to fix a bug where
KVM can run a VMCB with a stale ASID due to the tracking being
per-CPU, not per-VMCB
- Return INVALID_INPUT to the guest instead of exiting to userspace
with -EIO if KVM can't access "guest request" buffer, i.e. try to
keep the guest alive if the guest or userspace goofs
x86 (Intel):
- Enable Notify VM-Exits (now called Instruction Timeout in the SDM)
and Bus Lock VM-Exits for TDX guests when they're enabled by
userspace (KVM forgot to wire up the TDX Module knobs)
- Move all common (between VMX and TDX) APIs/helpers to
common.h/main.c, and change all namespace prefixes from "vmx" to
"vt"
- Fix a thankfully benign bug (due to other areas of KVM being
hardened) where userspace can bypass INIT_MEM_REGION's address wrap
check by providing a nr_pages that will overflow a u64 when
converted to bytes, and fix an also- benign off-by-one bug in the
check (inclusive vs. exclusive)
- Set the vmcs.GUEST_ACTIVITY_STATE back to ACTIVE when userspace
sets KVM's mp_state to anything other than HALTED, e.g. so that a
vCPU doesn't get stuck in HLT if userspace emulates RESET
guest_memfd:
- Take the invalidate lock when unbinding a dying file to fix a race
with kvm_gmem_invalidate_end() that results in KVM leaving the MMU
invalidation count elevated. Not taking the lock in the first place
was pure misguided paranoid
- When binding a memslot, purge the bindings if storing the new
memslot fails, as Xarray's "store range" API can subtly fail
partway through
- Establish memslot<=>guest_memfd bindings *after* the memslot is
ready, as the memslot becomes reachable the instant the binding is
installed
- Don't grab a page refcount when reloading an SNP VMSA and stop
returning a "struct page" from guest_memfd's PFN lookup altogether,
to ensure that KVM doesn't hold any unnecessary refcounts (the
lifetime of the page is ensured by MMU notifiers and similar
hooks). Preventing unnecessary refcounts greatly simplifies
supporting in-place SHARED=>PRIVATE conversions
- Add support for in-place PRIVATE<=>SHARED conversion, i.e. allow a
single guest_memfd instance to be used for both PRIVATE and SHARED
variations of CoCo guests' memory (though not at the same time).
This eliminates the need to double allocate guest memory for TDX
and SNP, and is basically a hard requirement for pKVM, which relies
on being able to preserve memory contents on conversions
- Hack-a-fix a deadlock bug in ->error_remove_folio() by returning
-EBUSY if the filemap invalidate lock is contended. Punt on a
proper fix for the moment, as a proper fix likely involves
reworking truncate_error_folio()
- Add a pile of selftests for in-place conversions
- Misc guest_memfd cleanups
Generic:
- Move some configuration items to preprocessor symbols, to help with
arm-on-s390's need to compile the same code twice with different
values
- Allow KVM implementations to choose alternative device names, also
for s390's support of ARM virtualmachines
- Switch the KVM-VFIO interface and external consumers over to
standard file-based reference counting, eliminating all external
KVM symbol exports
Selftests:
- Rework KVM selftest's handling of memory regions all so that PPC
can force its page table allocations to be naturally aligned
- PPC support
- Fix emulation of VMPTRST and VMPTRLD when eVMCS is in-use to match
real Hyper-V's behavior
- Saturate L2's TSC frequency if stacking L1 and L2 scaling
multipliers exceeds what hardware supports, as attempting to run L2
with an illegal multiplier will either cause VM-Entry to fail (VMX)
or trigger a #GP when writing MSR_AMD64_TSC_RATIO (SVM). The #GP is
thankfully benign in the grand scheme as even "unsafe" WRMSRs have
exception fixup
- Rework KVM selftest's handling of memory regions so that PPC can
force its page table allocations to be naturally aligned
- Clean up selftest's VMX instruction helpers, and drop an absurd
number of completely useless return values, e.g. functions that
unconditionally return %true and then have every caller assert
success
- Add selftests support for Zhaoxin CPUs
- Overhaul the TSC scaling test to add a regression test for the
saturation behavior, and to increase its coverage in general
- Fix selftests usage various NUMA syscalls to account for an
undocumented, but known since 2007, off-by-one kernel bug. Add
helpers to try and avoid re-introducing the same flaws in the
future
- Automatically run xAPIC IPI migration test (between NUMA nodes)
when possible, as the entire point of the test is verify KVM's
handling of page migration of the APIC backing page
- Misc cleanups"

Pull bpf updates from Alexei Starovoitov:
"Major changes:
- Introduce scalar evolution (SCEV) analysis in the verifier.
It infers how registers and stack slots change in a loop and lets
the verifier check bounded loops with induction variables as ranges
instead of walking every iteration. The number of processed insns
drops ten fold in programs with loops (Eduard Zingerman)
- Add 'callx' instruction: indirect call of a static BPF subprogram.
The address is taken with ld_imm64 or loaded from read-only data.
Supported by x86-64, arm64 and riscv64 JITs (Alexei Starovoitov, Pu
Lehui)
- Add unwind_goto and unwind_exit instructions, so that Rust panic or
C++ exception can run destructors of every frame it passes through.
The normal path is free of unwind code. Supported by x86-64 and
arm64 JITs (Alexei Starovoitov)
- Support programs compiled by rust-bpf: treat load and store through
a number as arena access with BPF_F_ARENA_SCALAR, accept rust names
in BTF (Alexei Starovoitov)
- Raise BPF program stack size from 512 bytes to 2 KiB on x86-64 and
arm64 (Kumar Kartikeya Dwivedi)

returned by value in BPF subprograms and kfuncs, and fix x86-64 and
arm64 trampolines for such arguments (Yonghong Song)
- Introduce a common way to attach struct_ops to a cgroup via
bpf_link. bpf_tcp_ops is the first user and mirrors TCP sock_ops
callbacks (Martin KaFai Lau, Amery Hung)
- Describe inlined functions in BTF. New kinds tell where the inline
sites are and how to fetch the arguments there.
CONFIG_DEBUG_INFO_BTF_INLINE keeps it apart from the main BTF in
.BTF.inline section or in btf_vmlinux_inline.ko (Alan Maguire)
- Fix many memory safety, lifetime and locking bugs in BPF core,
verifier, iterators, local storage, dynptr, devmap, cpumap and
seg6local (Josef Bacik, Alexei Starovoitov)
- Diff stat is dominated by selftests and by removal of
lib/test_bpf.c. Its 16k lines of instruction tests were converted
to BPF selftests that BPF CI runs on every architecture it covers
(Daniel Borkmann)
Other features and fixes:

Pull MM updates from Andrew Morton:
- "selftests/mm: improve khugepaged coverage" (Kiryl Shutsemau):
Give khugepaged a proper workout. Extend the tests to all supported
mTHP orders, check exactly which windows collapsed, and make scan
completion deterministic. Race collapse against faults, pinning, fork
and remap; verify that the contents survive.
Add coverage for whole-page-table zaps and memory pressure too.
- "selftests/mm: separate GUP microbenchmarking from functional testing"
(Sarthak Sharma):
Untangle GUP benchmarking from correctness testing. Move the
benchmark into tools/mm, add a standalone harness-based GUP selftest,
and move shared helpers into tools/lib/mm. Give each tool one job
instead of mixing timing measurements with correctness checks.
Cover the mapping, pinning and batch-size combinations explicitly.
- "mm: Switch device DAX to section-based vmemmap optimization" (Muchun
Song):
Apply section-based vmemmap optimization to device DAX. Rework the
backing metadata layout to save memory while preserving the handling
of device memory hotplug and its different alignment and lifetime
requirements.
- "mm: Introduce section-based vmemmap optimization for HugeTLB"
(Muchun Song):
Cut the memory consumed by HugeTLB's struct page array with
section-based vmemmap optimization. Arrange the metadata so large
huge pages need fewer backing pages, while keeping initialization,
teardown and the various hugepage configurations straight.
- "mm/huge_memory: clean up and decouple the anon and file split
helpers" (Kairui Song):
Separate anonymous and file-backed folio splitting, which have rather
different locking and bookkeeping requirements. Move the work into
separate helpers, drop dead checks and tidy swap-cache handling. Fix
error paths, including one that could leave a folio frozen.
Keep the swap cache cases separate from file-cache splitting.
- "mm: Unconditional per-VMA locks and cleanups" (Dave Hansen):
Make per-VMA locking unconditional and clean up the old conditional
code around it. This removes configuration-dependent plumbing and
lets callers depend on one locking model rather than carrying both
cases along.
- "memcg: remove the v1 soft limit" (Shakeel Butt):
Remove the old cgroup v1 memory soft-limit machinery. This has long
since been superseded by the newer memory-control interfaces; hauling
around a separate reclaim scheme for it no longer buys us much.
- "read proc/pid/smaps_rollup under per-vma lock" (Suren Baghdasaryan):
Read /proc/PID/smaps_rollup using per-VMA locks where possible,
rather than holding mmap_lock across the entire walk. Retain the
contention fallback and add tearing tests. This considerably reduces
latency when another thread is busy changing its mappings.
- "mm/damon: introduce data access-as-a-data attribute" (SJ Park):
Teach DAMON to expose memory access observations as data attributes,
making them available to the probe and filtering machinery. Extend
the interfaces, documentation and tests so the new information can be
used rather than merely collected.
- "Remove PG_private by using page/folio->private checks instead" (Zi
Yan):
Get rid of PG_private and use the folio's private pointer to say
whether private data is attached. Convert the filesystem users,
including erofs, f2fs and md, and clean up the old accessors and
flags. There are a few special cases, notably swapcache and hugetlb,
which need explicit care.
- "mm: make userland page table freeing RCU-safe" (Lorenzo Stoakes):
Make freeing userspace page tables safe against RCU readers. Sort out
the page-table lifetime and locking rules so walkers cannot stumble
over freed tables while mappings are being torn down.
- "make unused huge shrinker memcg aware" (Qi Zheng):
Make shmem's unused-huge-folio shrinker aware of memory cgroups, so
reclaim can find those folios under the right memcg. Wire up the
per-memcg tracking and its lifetime rules, and give the shrinklist
its own lockdep class to avoid spurious dependency reports.
- "mm: Drop pxd_ERROR()" (Anshuman Khandual):
Remove the old pxd_ERROR() page-table checks and their
architecture-specific baggage. Simplify the common page-table
interfaces and callers now that these checks no longer serve a
useful purpose.
- "memcg: group struct fields by access pattern" (Shakeel Butt):
Rearrange memcg's hot and cold fields according to how they're
actually accessed. Keep frequently updated counters and their
neighboring state from fighting over cachelines and reduce needless
cacheline traffic.
- "mm/damon/core: fix the size charged for a filter-trimmed region"
(Donggeun Yoo):
Fix DAMOS quota accounting when a filter trims a monitoring region.
Charge only the part left after filtering, not the original region,
and add KUnit coverage. Previously the excluded memory could eat into
the quota and make schemes run more slowly than requested.
- "mm/damon: add kunit and selftests for probes and probe weights" (SJ
Park):
Add more tests for DAMON probes and their weights, including
validation and the results reported to userspace. This is mostly
about catching regressions in the newer probe infrastructure before
they become harder to diagnose.
- "mm: memcontrol: constify the read side of the read side of the memcg
API" (Tal Zussman):
Mark the read-only parts of the memcg interface const, from folio and
lruvec accessors to counters and swap helpers. Most of this is
mechanical, but it makes the contracts clearer and lets the compiler
catch accidental writes.
- "mm/damon/vaddr: support {prep,apply}_probes" (SJ Park):
Support the new prepare/apply probe operations in DAMON's
virtual-address backend. This brings vaddr monitoring into line with
the probe infrastructure and makes the added probe types useful there
too.
- "mm/mglru: clean up folio counters and flag usage" (Kairui Song):
Simplify MGLRU's folio counters and flag handling. Remove redundant
accounting paths and make the state transitions easier to follow
without changing the intended reclaim policy.
- "arch, mm/execmem: resolve confusion about set_direct_map_valid_noflush()"
(Mike Rapoport (Microsoft)):
Clarify and straighten out the set_direct_map_valid_noflush()
interface across architectures and execmem. Make the requested
mapping changes and the callers' expectations agree, rather than
relying on subtly different architecture behavior.
- "mm: zswap: free cold writeback folios promptly" (Alexandre Ghiti):
Free zswap writeback folios as soon as their disk write completes.
They are cold temporary buffers, so putting them on the LRU only
makes reclaim rediscover them later. Extend swap-cache dropbehind and
let zswap keep these folios off the LRU altogether.
- "mm: gup: cleanup gup_fast call chain" (Aristeu Rozanski):
Clean up the GUP-fast call chain and simplify how the fast-path
helpers pass their arguments and results around. Keep the page-pin
behavior the same while making the call sequence easier to maintain.
- "mm: optimize zone-device memmap initialization" (Li Zhe):
Speed up initialization of zone-device struct pages. Avoid redundant
work when setting up large device-memory ranges, where touching every
descriptor can get expensive.
- "mm/zswap: shrink zswap_entry via a pool id" (Jianyue Wu):
Reduce the size of zswap_entry by storing a compact pool identifier
instead of a full pointer. Keep the pool lookup and lifetime handling
correct while saving per-entry metadata.
- "mm/damon: support access monitoring of hugetlb-backed memory"
(Krishna Iyer):
Let DAMON monitor hugetlb-backed memory too. Extend the relevant
access checks and add coverage so those mappings no longer fall
through a hole in the monitoring machinery.
- "mm/execmem: fixes and cleanups for the ROX cache" (Mike Rapoport):
Tidy execmem's read-only-executable cache and fix its handling of the
awkward allocation and release cases. The aim is to make the cache's
ownership and permission transitions more predictable.
- "zsmallc: remove old object read API" (Sergey Senozhatsky):
Drop zsmalloc's old object-read API and move its remaining users to
the supported access mechanism. This removes a duplicate interface
which we no longer need.
- "mm/mempolicy: stop copying state in the interleave paths" (Gregory
Price):
Stop copying mempolicy state in the interleave paths when a reference
to the existing policy will do. This avoids extra work and makes the
ownership rules less obscure.
- "mm/mglru: speed up inc_min_seq() and fix cold/hot inversions" (Barry
Song):
Make MGLRU's generation advancement cheaper and fix cases where cold
and hot folios end up in the wrong order. Adjust the counter and list
handling so reclaim doesn't keep passing over the better eviction
candidates.
- "mm: Fix MF_DELAYED handling on memory failure" (Lisa Wang):
Treat MF_DELAYED as a partially completed memory-failure operation,
not an outright failure. Propagate that result correctly through
shmem and the generic handler, fix the extra-reference accounting,
and add tests for the resulting SIGBUS behavior.
- "tools/mm/page_owner_sort: fix --sort, add module filter, improve
usage" (Ye Liu):
Fix page_owner_sort's --sort handling, add module-based filtering and
make the usage output more helpful. This makes the tool less
frustrating when tracking down who is holding on to pages.
- "mm/damon: move damos filter range arguments validation to core" (SJ
Park):
Move DAMOS filter range validation into the core, where all callers
can share it. Also close the sysfs read-twice races which could pass
inconsistent ranges, and add tests for invalid input.
- "mm/damon: misc cleanups" (Zenghui Yu):
Clean up a collection of small DAMON rough edges in the core,
interfaces and tests. No large behavior change here, just simpler
code and fewer opportunities for confusion.
- "mm/damon: cleanup code, add test cases, and update guidances in
docs" (SJ Park):
Clean up DAMON's core and interfaces, add missing test cases and
bring the documentation into line with the code. These changes should
make the newer facilities easier to understand and maintain.
- "mm/damon: introduce hugepage_size probe filter" (SJ Park):
Add a DAMON probe filter for hugepage size. Let users select a range
of folio sizes through sysfs, validate the range and document the new
interface, so monitoring can concentrate on memory backed by the
desired hugepage sizes.
- "selftests/mm: pagemap_ioctl test fixes and cleanups" (Zenghui Yu):
Fix some pagemap ioctl test assumptions and clean up their setup and
reporting. Make failures point to the operation that went wrong
rather than to test harness bookkeeping.
- "mm: avoid large folio splits when swap is unavailable" (Johannes
Weiner):
Avoid splitting large folios merely to attempt swap when no swap
space is available. There is little point paying for an expensive
split when reclaim cannot actually swap the resulting pages out.
- "mm: workingset: fix the shadow node budget under MGLRU" (Hui Zhu):
Fix the workingset shadow-node budget with MGLRU enabled. Keep the
shadow entries within the intended limits so refault tracking does
not quietly consume more metadata than it should.
- "selftests/mm: TAP output and global-state fixes" (Song Hu):
Fix selftests which produce misleading TAP output or fail to restore
global settings after a run. A test ought to leave the system as it
found it, particularly when a whole suite follows behind.
- "mm: remove page_swap_entry()" (Tal Zussman):
Remove page_swap_entry() and convert its remaining users to the folio
and swap-entry helpers. Lose an old page-level interface and make the
swap paths a little more consistent.
- "mm: refactor zonelist constructors and iterators" (Gregory Price):
Refactor the zonelist construction and walk helpers to reduce
duplicated logic. Keep the allocation ordering rules intact while
making it clearer how zones are selected.
- "mm: kmemleak: batch the struct page scan" (Breno Leitao):
Scan adjacent struct pages in batches instead of taking kmemleak_lock
once for every single page. This preserves scan coverage and the
lock-hold bound, while cutting overhead substantially on debug
kernels.
- "mm/damon: misc improvements in tests and documents" (Zenghui Yu):
Fix some DAMON selftests which leave kdamond running or fail under
Python safe-path mode, and improve the KUnit coverage and
documentation. Nothing especially glamorous, but these are worth
doing.
- "mm/damon: introduce probe_hits_wsum DAMOS core filter" (SJ Park):
Add a DAMOS core filter using weighted probe-hit counts. This gives
schemes another way to select regions based on what the monitoring
probes observed.
- "mm/mglru: fix ineffective memory protection for non-kswapd reclaim"
(Ridong Chen):
Fix MGLRU's memory protection handling for reclaim outside kswapd.
The protection settings weren't having the intended effect in these
paths, leaving protected memory more exposed than requested.
- "mm/damon: improve readability, clarity and test coverage" (SJ Park):
Simplify a handful of DAMON core helpers, clarify their behavior and
expand test coverage. There are no intended userspace-visible changes
in this batch.
- "mm: replace PF_KCOMPACTD/PF_KSWAPD with kthread_func()" (Kefeng
Wang):
Stop identifying reclaim and compaction workers through the PF_KSWAPD
and PF_KCOMPACTD task flags. Use their kthread functions instead and
remove the redundant flag plumbing.
- "mm/hugetlb: fix surplus accounting and availability checks during
demotion" (Longlong Xia):
Fix HugeTLB surplus accounting and availability checks when demoting
huge pages. Keep the counters and reservation decisions consistent as
one huge page turns into several smaller ones.
- "mm/damon: add kunit tests for probe_hits handling and probe params
validation" (Jason Angelov):
Add KUnit tests for DAMON probe-hit handling and invalid probe
parameters. These cover edge cases that were too easy to miss in
ordinary monitoring tests.
- "mm/damon: fix misc bugs in kunit, quota goals and sysfs refresh_ms"
(SJ Park):
Fix a few DAMON bugs in KUnit tests, quota-goal handling and the
sysfs refresh interval. Small fixes, but the incorrect results and
control behavior were real.
- "mm: zswap: optimize zswap invalidate and store" (Kefeng Wang):
Simplify zswap's invalidate and store paths to avoid avoidable
lookups and work. Keep the entry lifetime rules intact while making
those frequent operations cheaper.
- "mm: replace custom ratelimiting logic" (Pedro Falcato):
Replace hand-rolled MM rate limiting with the common kernel helpers.
There is no need to maintain another local version of the same
mechanism.
- "mm/vmalloc: minor cleanups" (Ye Liu):
Tidy some vmalloc initialization and reporting code, and pull
duplicated vmap-area insertion work into a helper. No functional
changes are intended.
- "mm/mglru: clean up isolate_folios for readability and clarity"
(Ridong Chen):
Clean up MGLRU's isolate_folios() so the decisions are easier to read
and verify. Keep reclaim behavior unchanged while removing
unnecessary twists in the control flow.
- "Catch automatic storage in IDA and Maple Tree definitions" (Yury
Norov):
Catch IDA and maple-tree definitions placed in automatic storage
where the lifetime rules are wrong or easy to get wrong. Add checks
so such mistakes are harder to slip through unnoticed.
- "mm, swap: some random fixes and cleanups" (Kemeng Shi):
Fix and simplify a few unrelated swap paths, removing redundant work
and tidying up error handling. A small collection of things which
were better fixed than left lying around.
- "mm/page_io: folio conversion cleanups" (Tal Zussman):
Finish some page-to-folio conversions in swap I/O, removing obsolete
wrappers and using folio operations consistently. The I/O behavior is
intended to remain the same.
- "mm/swap: skip empty clusters in the swapoff scan" (Youngjun Park):
Skip empty swap clusters during swapoff instead of walking slots
which have nothing to release. This avoids pointless work on sparsely
used swap devices.
- "mm: trace: decode architecture-specific VMA flags" (Meijing Zhao):
Teach the VMA trace output to decode architecture-specific flags,
rather than leaving them as unexplained bits. That should make
tracing a good deal more useful when debugging unusual mappings.
- "mm, swap: don't spin on a bad swap entry" (Breno Leitao):
Stop repeatedly retrying a swap entry which is already known to be
bad. Make the error path terminate cleanly instead of wasting CPU
chasing an entry that cannot be used.
- "mm/page_isolation: fix UBSAN shift-out-of-bounds in
isolate_single_pageblock" (Qi Xi):
Fix an out-of-range shift in isolate_single_pageblock() and tighten
its associated boundary handling. UBSAN found the issue; the result
should be more robust pageblock isolation.
- "mm: khugepaged: fix tracepoint UAF" (Vernon Yang):
Fix a use-after-free in khugepaged tracepoint handling. Make sure the
information recorded by tracing stays valid for as long as the trace
event needs it.
- "mm/damon: fix DAMOS bugs in core, paddr and vaddr" (SJ Park):
Fix several DAMOS problems across the core and physical- and
virtual-address backends. The changes close error cases and bring the
implementations back into agreement.
- "mm/hugetlb_cgroup: move the per-node usage along with the folio"
(Hongfu Li):
Move HugeTLB per-node usage accounting when folios migrate between
nodes or are reparented to another cgroup. Otherwise numa_stat can
retain stale charges and even underflow when the folio is freed.
- "docs/core-api: memory-allocation: add k[mz]alloc_obj() and clarify
kmalloc" (Mike Rapoport):
Document the typed k[mz]alloc_obj() allocation helpers and clear up
some kmalloc guidance. Make it easier for callers to choose the right
interface.
- "selftests/mm: Validate selections and scope memfd_secret setup"
(Tianyi Chen):
Check selftest selections before running and confine memfd_secret
setup to the cases that actually need it. Avoid confusing failures
caused by the test harness itself.
- "mm/damon: move zero damos quota target_value handling to the core
layer" (SJ Park):
Handle a zero DAMOS quota goal target in the core rather than making
each user of the interface invent its own rule. Keep quota decisions
consistent across callers.
- "mm/damon: Introduce a huge page collapsing mechanism using auto
tuning" (Asier Gutierrez):
Add an auto-tuned DAMON mechanism for collapsing huge pages. Use
monitoring feedback to decide when collapse is worthwhile rather than
forcing one fixed policy onto every workload.
- "kmemleak: fix stale documentation and raise the verbose default"
(Breno Leitao):
Bring the kmemleak documentation up to date and require a third
confirming scan before verbose kernels print a suspected leak. The
extra scan helps suppress transient false positives in noisy debug
builds.
- "mm/memory: improve insert_pages() error handling" (Avi Weiss):
Tighten insert_pages() error handling so partial failures are
reported and cleaned up consistently. The caller should not have to
guess how far the operation got.
- "mm/damon: allow NULL or unstarted damon_ctx parameter for
damon_call()" (SJ Park):
Make damon_call() handle NULL and not-yet-started contexts safely.
Simplify the rules for callers and avoid an indefinite wait on an
invalid state.
- "mm/damon: introduce pgidle_set probe filter type" (SJ Park):
Add a pgidle_set DAMON probe filter, giving monitoring users another
way to select pages by their idle-tracking state. Wire it through the
filter interfaces and tests.
- "mm/damon/core: remove unused helper functions" (Cheng-Han Wu):
Remove DAMON core helpers which no longer have callers. Keep the API
surface smaller rather than retaining dead code just in case.
- "mm: stop calling pmd_folio() on special PMDs" (Gregory Price):
Avoid calling pmd_folio() on special PMD mappings that have no struct
page. The old assumption could fault in procfs walkers; use the
normal-folio checks and handle those mappings properly.
- "mm: remove three unused helpers from mm.h" (Tal Zussman):
Remove three unused helpers from mm.h. Fewer obsolete interfaces for
the next person to stumble over.
- "mm/damon: improvements in efficiency, error handling, documents"
(Liew Rui Yan):
Skip needless DAMOS quota work once the quota is full, propagate a
missing sysfs error and tidy a couple of comments. The ignored error
could make a monitoring-start request appear successful when it
wasn't.
- "docs/mm/damon/design: add explanation of nr_snapshots" (Liew Rui
Yan):
Explain DAMON's nr_snapshots accounting in the design documentation
and straighten out the associated terminology. Make it clearer what
users should expect from that counter.
- "selftests/cgroup: fixes for test_zswap on single core VM" (Wilson
Felipe Pereira):
Fix two test_zswap failures on single-CPU VMs. Wait for the exiting
child's cgroup to become unpopulated before reconfiguring it, and
avoid another test assumption which breaks under constrained
scheduling.
- "docs/ksm: fix advisor documentation and comment" (Jinjiang Tu):
Correct the KSM advisor documentation and a misleading code comment.
Keep the description aligned with how the advisor actually works.
- "Fix bugs in HugeTLB allocation when mem_cgroup_charge_hugetlb()
fails" (Ackerley Tng):
Fix HugeTLB allocation cleanup when the memcg charge fails. Make sure
failure exits undo what was allocated rather than leaving stale
accounting or resources behind.
- "mm, memcg: fix memory.peak reset clobbering other fds' watermark"
(Ridong Chen):
Fix memory.peak reset handling so resetting one file descriptor
doesn't overwrite the watermark kept for another. Keep those per-open
measurements independent as intended.
- "mm: reject zone device folios in more folio walkers" (Gregory
Price):
Reject zone-device folios in page walkers that cannot safely handle
them. Extend the existing checks rather than assuming every folio has
ordinary system-memory backing.
- "percpu: remove code with no effect" (Sang-Heon Jeon):
Remove a few pieces of percpu code which no longer do anything. There
is no reason to keep maintaining dead paths.

SPI NOR changes for 7.4
- Support for new Macronix and (lots of) Winbond flash devices
- The addition of the Winbond flashes was accompanied by a big rewrite of the
status register handling. There were many small helper functions to enable
quad I/O mode in many different ways. That's now consolidated in one generic
function.
- The SFPD handling was reworked. It used to be only parsed for flashes present
in the in-kernel database which had any of the multi-I/O bit set - or with the
addition of generic flash driver for any unknown flashes. This left a gap
where SFDP wasn't handled and it turns out newer flashes (with SFDP support)
will reused IDs of just these old flashed. With the rework, SFDP is tried to
be parsed for any flashes and will amend the information which is already
present in the in-kernel database.
- SFDP size limit was increased to 16KiB. There are flashes which have some
larger gaps between tables and thus exceeds the former 4KiB limit.
- Flash fixups are getting more and more common. Due to this, the fixups are now
a separate list (per manufacturer) instead of being attached to a specific
flash. A new .match() callback makes them more flexible, when one is applied.
- 1-1-8 and 1-8-8 modes are now supported with larger flashes which needs 4byte
addresses.

Raw NAND:
- The Qualcomm controller driver has been cleaned up again.
- Arasan and IBM have been improved/created.
- Reflect that ESMT and GigaDevice share ID 0xc8, and disable broken
timings feature on GD9FU2G8F3A.
- Platform data support has been dropped from the lpc32xx drivers.
SPI NAND:
- Heyangtek uses two bytes for the BBM like every other device.
- Winbond: Add support for W25N04LW and W25N08LW.
- Support for ISSI SPI NAND flashes.
Then there is the load of API updates and misc AI fixes.

eisa_enumerator() trusts the contents of the EISA EEPROM. The number
of slots is read from the EEPROM header and used to access the slot
records at HPEE_SLOT_INFO(i) = 20 + 48*i within the fixed-size
eeprom_buf (HPEE_MAX_LENGTH, 8192 bytes) without any bound check. As
struct eeprom_eisa_slot_info is 48 bytes, only 170 records fit into the
buffer, but num_slots is a u8 and may be up to 255, so a corrupted
EEPROM makes the code read up to about 4 kB past the end of the buffer
(e.g. record 254 is accessed at offset 20 + 48*254 = 12212).
parse_slot_config() has the same kind of problem: it clamps
config_data_length against HPEE_MAX_LENGTH but does not take
config_data_offset into account, so the parser can walk past the end of
the buffer even when the offset itself is valid.
Clamp the number of slots so that all slot records fit into the buffer,
and hand the number of bytes actually available to parse_slot_config()
and bound the parse by it.

Pull networking updates from Paolo Abeni:
"This includes a significant number of low-priority fixes - especially
in the NIC drivers area - that we deferred from the last few RCs in
the previous cycle, which can't be easily outlined in the synopsis
below.
Core & protocols:
- Continue the work on removing rtnl_lock dependencies:
- per-netns ARP and ND neighbour tables, with the default settings
now configurable per netns (inheritance from init_net is
controlled by the new net.core.neigh_inherit_init_net sysctl)
- RCU-protected configuration and rtnl_lock-less fill_info() for
hsr, netkit, sit, vlan and vxlan devices
- per-netns device unregistration for ip tunnel and gre devices
- use the netdev instance lock instead of rtnl_lock when reading
speed and duplex via sysfs
- batch the flushing of uncached routes at device unregistration
time, relieving rtnl_lock contention on netns dismantle.
- Add hardware pacing offload support, admin-controlled via a new
rtnetlink attribute, with sch_fq integration (implemented in idpf).
- Re-segment BIG TCP GSO packets into GSO packets fitting the egress
device limits instead of plain MSS-sized segments, improving
throughput for mixed BIG TCP / non-BIG TCP paths by up to 70%.
- Generate RSS keys that spread flows over all the RX queues; the
previous random keys could leave some queues unused.
- Optimize the bridge VLAN forwarding paths: cache the port-VLAN in
fdb entries and consider only VLAN members when flooding, for ~10%
more Mpps in the fdb forwarding path.
- A few TCP/IP performance improvements aimed at efficient cache
usage and reducing contention.
- Add the TCP ROCCET congestion control, a CUBIC variant aimed at
avoiding bufferbloat in cellular networks.
- Continue the conversion of getsockopt callbacks to sockopt_t.
- Add an ethtool command to list the front-facing ports of an
interface, including SFP cages and modules, using the phy_port
representation.
- Enable BIG TCP support for bareudp tunnels.
- Remove the IPV6_ADDRFORM socket option and disallow buggy TCP state
transitions (listen() + shutdown() + connect() and connect() +
connect(AF_UNSPEC) + listen()).
- Remove most BUG_ON()s from core packet processing, replacing them
with error paths.
Wireless:
- Latency improvements, including lockless station get/dump and
beacon updates, plus RTNL reduction and locking cleanups.
- Infrastructure for non-station TX/RX with MLO.
- NAN (Wi-Fi Aware) Instant Communication support and other NAN
improvements.
- Control frame Integrity Protocol (CIP) and protected TWT support.
- Improvements for AP regulatory checks.
Netfilter:
- Disable br_netfilter in user namespaces and schedule it for removal
in 2027.
- Restrict the raw table in nft_compat to the specific family, hook
and priority.
- Prepare the flowtable for mixed IPv4-over-IPv6 tunneling (and vice
versa).
- Use GFP_KERNEL_ACCOUNT for most netfilter allocations, for better
integration with memcg.
- Allow discovering conntrack zone filtering support in ctnetlink
dumps, and fix nfnetlink_hook handling of large dumps.
Deletions:
- Move the LLC type 2 sockets out of tree. There are no known users
and the code attracts a never-ending stream of LLM-driven fixes.
Device drivers:
- New drivers:
- Meta Platforms NIC (mpnic), the second-generation NIC from Meta

Pull rdma updates from Jason Gunthorpe:
"A smaller cycle for features, still mostly AI and tool found bug fixes
for long standing issues:
- Bug fixes and minor cleanups across bnxt_re, cxgb4, EFA, ERDMA,
HFI1, HNS, ionic, iRDMA, mlx4/mlx5, rdmavt, rtrs, RXE, SIW, SRP,
isert and IPoIB. Lots of error unwind leaks, integer overflows, and
use after free during teardown from timers/work that was not
cancelled
- Core fixes for uverbs DMABUF lifetime, RMPP reassembly use after
free, multicast rb-tree corruption, restrack, and a user
triggerable NULL deref when creating a WQ without a CQ
- Prevent userspace from getting a writable mmap of the cxgb4 status
page and the mlx4 clock page
- Many rxe hardening fixes for bad user and network input, plus
netdev and tunnel socket lifetime fixes
- Peer supplied values are now validated in rtrs-clt, which is remote
triggerable
- umem now picks the DMA direction from the access flags instead of
always using DMA_BIDIRECTIONAL, so an IOMMU can stop the device
from writing to read-only memory. Several drivers were fixed to pin
CQ and queue memory as writable to go along with this
- SRQ support, firmware assigned CQ IDs and RCQ userspace support for
ionic
- RC QP improvements in MANA: MMQ creation, fixed size send WQEs and
power of two send queues. Also multi-port GSI QPs and a rework of
the UD send/receive and CQ polling paths
- Relaxed ordering MRs for EFA
- Non-contiguous kernel QP and CQ buffers for ERDMA
- Move the mlx5 data direct infrastructure from mlx5_ib to mlx5_core
so netdev can use it too. The data direct PCI driver is now named
"mlx5_dd"
- debugfs knob in hns to fix the SL used by the GSI QP, working
around a HW problem with dropped CQEs
- Selftest fixes, removal of the qib sysfs ABI docs, DT schema
conversion for hns, and MANA maintainer handover"
