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 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 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)

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:

devm_clk_get_optional_enabled() (Felix Gu)
TI Keystone PCIe controller driver:
- Remove device links to PHY, which are redundant because the PHY

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)

Pull spi updates from Mark Brown:
"Quite a lot of work in the SPI subsystem this time around, almost all
in drivers rather than the core.
As well as the general cleanup/fix work we're seeing over most of the
kernel there's been some substantial performance work to two existing
drivers and support for a number of new devices including a couple of
new drivers. There was also a big overhaul of the spidev_test utility
from the Pengutronix people.
- Improvements for spidev_test to cover additional use cases, plus be
a bit easier to use.
- Substantial performance work in both DesignWare and Tegra210 QSPI
drivers, making their interrupt handling more efficient to drive up
hardware utilisation.
- Documentation clarifications.
- Fixes for some runtime PM and error handling issues.
- Support for Nuvoton MA35D1, Qualcomm QPIC SNAND v2, Renesas R-Car

"Nothing stands out as particularly interesting, it's been a calm
cycle. We have three new drivers, support for more models and lots of
updates across many modules (details are in the signed tag as usual).
There are also some minor changes and additions to the in-kernel GPIO
API.
GPIO core:
- provide a new controller API: gpiochip_generic_get_config()

- stop needlessly reading gpio_chip::base in gpio-pxa
- add support for tracking of direction of generic GPIO chips with no
direction registers via pinctrl backend to gpio-mmio (use the new
core API: gpiochip_generic_get_config())
- use the "safe" variants of debugfs_create_file() in
gpio-sloppy-analyzer
- use device name as GPIO chip label in gpio-omap
- refactor bit ops in gpio-dln2

Pull Kbuild / Kconfig updates from Nathan Chancellor:
"Kbuild:
- Suppress compiler flags in debug info for external module builds
- Use '-fmacro-prefix-map' in more places in the build
- Merge initial set of changes from Lorenzo's speed up series, along
with some fixes found through testing:
- Avoid allocating .modinfo in vmlinux
- Speed up kallsyms by indexing symbols by token and outputting
binary data to disk directly then including in assembly via
.incbin
- Don't sort $(NM) output when unnecessary
- Only emit relocations on the final vmlinx link
- Reimplement mksysmap in C
- Move many cc-option and ld-option calls into the Kconfig stage to
cache their results
- Use pigz for gzip compression when available
- Move gen_init_cpio and gen_initramfs.sh from usr/ to scripts/
- Add a TOML configuration to scripts/container and update
documentation accordingly
- Add a generic, opt-in mechanism for checking that headers can
compile standalone
- Update machine function splitting argument for LLVM 24 rename in
AutoFDO build
- Miscellaneous minor clean ups, fixes, and hardening, mostly
found/fixed via LLMs
Kconfig:
- Turn recursive ranges into an error
- Fix savedefconfig for defaults that were adjusted for being out of
range and revert a previously applied workaround
- Improvements and hardening around integer and hexadecimal values
- Emit a warning when selecting or implying a choice symbol, which
has no effect
- Emit a warning when KCONFIG_PROBABILITY is malformed
- Introduce def_string / def_int / def_hex to mirror the existing
def_bool / def_tristate to succinctly set a value and type at the
same time.
- Add cc-option-str and ld-option-str macros to act like Kbuild's
cc-option and ld-option, returning the string when the option is
supported, allowing many checks to be moved into Kconfig
- Minor usability improvements to Kconfig tests"

Commit 95308225e5ba ("dma-buf: Rename dma_buf_move_notify() to
dma_buf_invalidate_mappings()") left the DMABUF section of the P2PDMA
documentation pointing at move_notify(), a symbol that no longer exists.
Readers grepping for it find nothing, and this is the only place in
Documentation/ describing the revocation requirement.
Name the current function and record that importers which cannot unmap
within bounded time have to be rejected at attach time, which is what makes
the synchronous unmap on remove() achievable.
