Replace the #include of <linux/mod_devicetable.h> by the more specific
<linux/device-id/*.h> where applicable. For most cases the include
can be dropped completely, only a few drivers need one or two headers
added.

Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Remove MPS/MRRS Kconfig settings (CONFIG_PCIE_BUS_*) that worked
     around a WiFi device defect; use a quirk or boot-time
     "pci=pcie_bus_tune_*" kernel parameter instead (Bjorn Helgaas)

   - Always lift 2.5GT/s restriction in PCIe failed link retraining to
     avoid clamping a link to 2.5GT/s after hot-plug changes the device
     (Maciej W. Rozycki)

   - Request bus reassignment when not probe-only to fix an enumeration
     regression on Marvell CN106XX and possibly other DT-based systems
     (Ratheesh Kannoth)

   - Fix procfs race between pci_proc_init() and pci_bus_add_device()
     that resulted in 'proc_dir_entry ... already registered' warnings
     and pointer corruption (Krzysztof Wilczyński)

   - Fix sysfs race that causes 'duplicate filename' warnings and boot
     panics by converting PCI resource files to static attributes
     (Krzysztof Wilczyński)

   - Expose sysfs 'resourceN_resize' attributes only on platforms with
     PCI mmap (Krzysztof Wilczyński)

   - Require CAP_SYS_ADMIN to write to sysfs 'resourceN_resize'
     attributes (Krzysztof Wilczyński)

   - Add security_locked_down(LOCKDOWN_PCI_ACCESS) to alpha PCI resource
     mmap path to match the generic path (Krzysztof Wilczyński)

   - Use kstrtobool() to parse the 'rom' attribute input to avoid the
     unexpected behavior of enabling the ROM when writing '0' with no
     trailing newline (Krzysztof Wilczyński)

  Resource management:

   - Improve resource claim logging for debuggability (Ilpo Järvinen)

   - Clean up several uses of const parameters (Ilpo Järvinen)

   - Check option ROM header signatures and lengths before accessing to
     avoid page faults and alignment faults (Guixin Liu)

  ASPM:

   - Don't reconfigure ASPM when entering low-power D-state; only do it
     when returning back to D0 (Carlos Bilbao)

  Power management:

   - During suspend, set power state to 'unknown' for all devices, not
     just those with drivers (Lukas Wunner)

   - Skip restoring Resizable BARs and VF Resizable BARs if device
     doesn't respond to config reads, to avoid invalid array accesses
     (Marco Nenciarini)

   - Add pci_suspend_retains_context() so drivers can tell whether
     devices retain internal state across suspend/resume, since some
     platforms reset devices on suspend; use this in nvme to avoid
     issues on Qcom RCs (Manivannan Sadhasivam)

  Power control:

   - Only to power on/off devices that actually support power control to
     avoid poking at incompatible devices mentioned in DT (Manivannan
     Sadhasivam)

  Virtualization and resets:

   - Log device readiness timeouts as errors, not warnings, because the
     device is likely unusable in this case (Bjorn Helgaas)

   - Wait for device readiness after soft reset (D3hot ->
     D0uninitialized transition), when the device may respond with
     Request Retry Status (RRS) if it needs more time to initialize
     (Bjorn Helgaas)

   - Drop unnecessary retries when restoring BARs because resets should
     now already include all required delays (Lukas Wunner)

   - Avoid FLR for MediaTek MT7925 WiFi, where FLR fails after a VM
     terminates uncleanly (Jose Ignacio Tornos Martinez)

   - Avoid SBR for Qualcomm WCN6855/WCN7850 WiFi, SDX62/SDX65 modems,
     which seem not to support it correctly (Jose Ignacio Tornos
     Martinez)

  Peer-to-peer DMA:

   - Prevent P2PDMA as well as CPU access to non-mappable BARs, e.g.,
     s390 ISM BARs (Matt Evans)

   - Add Intel QAT, DSA, IAA devices to whitelist (Lukas Wunner)

  Endpoint framework:

   - Add endpoint controller APIs for use by function drivers to
     discover auxiliary blocks like DMA engines (Koichiro Den)

   - Remember DesignWare eDMA engine base/size and expose them via the
     EPC aux-resource API (Koichiro Den)

   - Add endpoint embedded doorbell fallback, used if MSI allocation
     fails (Koichiro Den)

   - Validate BAR index and remove dead BAR read in endpoint doorbell
     test (Carlos Bilbao)

   - Unwind MSI/MSI-X vectors if NTB initialization fails part-way
     through (Koichiro Den)

   - Cache sleepable pci_irq_vector() value at ISR setup to avoid
     calling it from hardirq context (Koichiro Den)

   - Call sleepable pci_epc_raise_irq() from a work item instead of
     atomic context, e.g., when setting bits in NTB peer doorbells in
     the ntb_peer_db_set() path (Koichiro Den)

   - Report 0-based vNTB doorbell vector to account for link event 0 and
     historically skipped slot 1 (Koichiro Den)

   - Prevent configfs writes to vNTB db_count and other values that are
     already in use after EPC attach (Koichiro Den)

   - Account for vNTB db_valid reserved slots (link event 0 and
     historically skipped slot 1) so they don't appear as valid
     doorbells (Koichiro Den)

   - Implement vNTB .db_vector_count()/mask() for doorbells so clients
     can use multiple vectors and avoid thundering herds (Koichiro Den)

   - Report 0-based NTB doorbell vector to account for link event 0 and
     historically skipped slot 1 (Koichiro Den)

   - Fix doorbell bitmask and IRQ vector handling to clear only
     specified bits, use the correct vector for non-contiguous Linux IRQ
     numbers, and validate incoming vectors (Koichiro Den)

   - Implement NTB .db_vector_count()/mask() for doorbells so clients
     can use multiple vectors (Koichiro Den)

  Native PCIe controller infrastructure:

   - Add pci_host_common_link_train_delay() for the mandatory delay
     after > 5GT/s Link training completes and use it for cadence HPA,
     j721e, LGA; dwc; aardvark, mediatek-gen3, rzg3s (Hans Zhang)

   - Protect root bus removal with rescan lock in altera, brcmstb,
     cadence, dwc, iproc, mediatek, plda, rockchip to prevent
     use-after-free or crashes when racing with sysfs rescan or hotplug
     (Hans Zhang)

   - Add pci_host_common_parse_ports() for use by any native driver to
     parse Root Port properties (per-Link features like width, speed,
     PHY, power and reset control, etc should be described in Root Port
     stanzas, not the host bridge; currently only reset GPIOs
     implemented) (Sherry Sun)

  New native PCIe controller drivers:

   - Add DT binding and driver for UltraRISC DP1000 PCIe controller

  Broadcom STB PCIe controller driver:

   - No change, but products using certain WiFi devices may be affected
     by removal of CONFIG_PCIE_BUS_* (see above)

  Freescale i.MX6 PCIe controller driver:

   - Move IMX6SX_GPR12_PCIE_TEST_POWERDOWN handling into the core reset

   - Add .get_ltssm() callback to get the LTSSM status without DBI,
     since DBI may be inaccessible after PME_Turn_Off (Krishna Chaitanya

Pull MM updates from Andrew Morton:

 - "selftests/mm: clean up build output and verbosity" (Li Wang)

   Remove some noise from the MM selftests build

 - "mm: Free contiguous order-0 pages efficiently" (Ryan Roberts)

   Speed up the freeing of a batch of 0-order pages by first scanning

   to the releasing of frozen pages

 - "mm/damon: introduce DAMOS failed region quota charge ratio"
   (SeongJae Park)

   Address a DAMOS usability issue: The DAMOS quota often exhausts
   prematurely because it charges for all memory attempted, causing slow
   and inconsistent performance when actions fail on unreclaimable
   memory.

   To fix this, a new feature lets users set a smaller, flexible quota
   charge ratio (via a numerator and denominator) for failed regions.
   Since failed actions cause less overhead, reducing their quota cost
   ensures more predictable and efficient DAMOS processing

  ...

pnv_kexec_wait_secondaries_down() calls get_cpu() to obtain the current
CPU id but never calls the matching put_cpu(), leaking one
preempt_disable() nesting level on every invocation.

In practice the imbalance does not trigger a visible splat because the
kexec teardown path is a one-way trip: IRQs are already disabled, no
schedule() occurs after the leak, and default_machine_kexec() overwrites
preempt_count with HARDIRQ_OFFSET before jumping into kexec_sequence()
which never returns. However the bookkeeping is still wrong.

The function only needs the current CPU id, and this path runs with
interrupts disabled and the CPU pinned, so the preempt_disable()
side-effect of get_cpu() is unnecessary. Replace it with
raw_smp_processor_id().

Pull driver core updates from Danilo Krummrich:
 "Deferred probe:
   - Fix race where deferred probe timeout work could be permanently
     canceled by using mod_delayed_work()
   - Fix missing jiffies conversion in deferred_probe_extend_timeout()
   - Guard timeout extension with delayed_work_pending() to prevent
     premature firing
   - Use system_percpu_wq instead of the deprecated system_wq
   - Update deferred_probe_timeout documentation

  device:
   - Replace direct struct device bitfield access (can_match, dma_iommu,
     dma_skip_sync, dma_ops_bypass, state_synced, dma_coherent,
     of_node_reused, offline, offline_disabled) with flag-based
     accessors using bit operations
   - Reject devices with unregistered buses
   - Delete unused DEVICE_ATTR_PREALLOC()
   - Add low-level device attribute macros with const show/store
     callbacks, allowing device attributes to reside in read-only memory
   - Move core device attributes to read-only memory
   - Constify group array pointers in driver_add_groups() /
     driver_remove_groups(), struct bus_type, and struct device_driver

  device property:
   - Fix fwnode reference leak in fwnode_graph_get_endpoint_by_id()
   - Initialize all fields of fwnode_handle in fwnode_init()
   - Provide swnode_get()/swnode_put() wrappers around kobject_get/put()
   - Allow passing struct software_node_ref_args pointers directly to
     PROPERTY_ENTRY_REF()

  driver_override:
   - Migrate amba, cdx, vmbus, and rpmsg to the generic driver_override
     infrastructure, fixing a UAF from unsynchronized access to
     driver_override in bus match() callbacks
   - Remove the now-unused driver_set_override()

  firmware loader:
   - Fix recursive lock deadlock in device_cache_fw_images() when async
     work falls back to synchronous execution
   - Fix device reference leak in firmware_upload_register()

  platform:
   - Pass KBUILD_MODNAME through the platform driver registration macro
     to create module symlinks in sysfs for built-in drivers; move
     module_kset initialization to a pure_initcall and tegra cbb
     registration to core_initcall to ensure correct ordering
   - Pass THIS_MODULE implicitly through a coresight_init_driver() macro

  sysfs:
   - Upgrade OOB write detection in sysfs_kf_seq_show() from printk to
     WARN
   - Add return value clamping to sysfs_kf_read()

  Rust:
   - ACPI:

     Fix missing match data for PRP0001 by exporting
     acpi_of_match_device()

   - Auxiliary:

     Replace drvdata() with dedicated registration data on
     auxiliary_device. drvdata() exposed the driver's bus device private
     data beyond the driver's own scope, creating ordering constraints
     and forcing the data to outlive all registrations that access it.
     Registration data is instead scoped structurally to the
     Registration object, making lifecycle ordering enforced by
     construction rather than convention.

   - Rust-native device driver lifetimes (HRT):

     Allow Rust device drivers to carry a lifetime parameter on their
     bus device private data, tied to the device binding scope -- the
     interval during which a bus device is bound to a driver. Device
     resources like pci::Bar<'a> and IoMem<'a> can be stored directly in
     the driver's bus device private data with a lifetime bounded by the
     binding scope, so the compiler enforces at build time that they do
     not outlive the binding. This removes Devres indirection from every
     access site and eliminates try_access() failure paths in
     destructors.

     Bus driver traits use a Generic Associated Type (GAT) Data<'bound>
     to introduce the lifetime on the private data, rather than
     parameterizing the Driver trait itself. Auxiliary registration
     data, where the lifetime is not introduced by a trait callback but
     must be threaded through Registration, uses the ForLt trait (a
     type-level abstraction for types generic over a lifetime).

  Misc:
   - Fix DT overlayed devices not probing by reverting the broken
     treewide overlay fix and re-running fw_devlink consumer pickup when
     an overlay is applied to a bound device
   - Use root_device_register() for faux bus root device; add sanity
     check for failed bus init
   - Fix dev_has_sync_state() data race with READ_ONCE() and move it to
     base.h
   - Avoid spurious device_links warning when removing a device while
     its supplier is unbinding
   - Switch ISA bus to dynamic root device
   - Fix suspicious RCU usage in kernfs_put()
   - Remove devcoredump exit callback
   - Constify devfreq_event_class"

Pull vfs inode updates from Christian Brauner:
 "This extends the lockless ->i_count handling.

  iput() could already decrement any value greater than one locklessly
  but acquiring a reference always required taking inode->i_lock. Now
  acquiring a reference is lockless as long as the count was already at
  least 1, i.e., only the 0->1 and 1->0 transitions take the lock.

  This avoids the lock for the common cases of nfs calling into the
  inode hash and btrfs using igrab(). Cleanup-wise icount_read_once() is
  added to line up with inode_state_read_once() and the open-coded
  ->i_count loads across the tree are converted, and ihold() is
  relocated and tidied up.

  On top of that some stale lock ordering annotations are retired from
  the inode hash code: iunique() no longer takes the hash lock since the
  inode hash became RCU-searchable and s_inode_list_lock is no longer
  taken under the hash lock either"

* tag 'vfs-7.2-rc1.inode' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs:
  fs: retire stale lock ordering annotations from inode hash
  fs: allow lockless ->i_count bumps as long as it does not transition 0->1
  fs: relocate and tidy up ihold()
  fs: add icount_read_once() and stop open-coding ->i_count loads

The lack of get_direction() callbacks in this driver causes GPIOLIB to
emit a warning. Implement them for 16- and 32-bit variants.
