security: Add KUnit tests for kuid_root_in_ns and vfsuid_root_in_currentns
Add comprehensive KUnit tests for the namespace-related capability
functions that Serge Hallyn refactored in commit 9891d2f79a
("Clarify the rootid_owns_currentns").

The tests verify:
- Basic functionality: UID 0 in init namespace, invalid vfsuid,
  non-zero UIDs
- Actual namespace traversal: Creating user namespaces with different
  UID mappings where uid 0 maps to different kuids (e.g., 1000, 2000,
  3000)
- Hierarchy traversal: Testing multiple nested namespaces to verify
  correct namespace hierarchy traversal

This addresses the feedback to "test the actual functionality" by
creating real user namespaces with different values for the
namespace's uid 0, rather than just basic input validation.

The test file is included at the end of commoncap.c when
CONFIG_SECURITY_COMMONCAP_KUNIT_TEST is enabled, following the
standard kernel pattern (e.g., scsi_lib.c, ext4/mballoc.c). This
allows tests to access static functions in the same compilation unit
without modifying production code based on test configuration.

The tests require CONFIG_USER_NS to be enabled since they rely on user
namespace mapping functionality. The Kconfig dependency ensures the
tests only build when this requirement is met.

All 7 tests pass:
- test_vfsuid_root_in_currentns_init_ns
- test_vfsuid_root_in_currentns_invalid
- test_vfsuid_root_in_currentns_nonzero
- test_kuid_root_in_ns_init_ns_uid0
- test_kuid_root_in_ns_init_ns_nonzero
- test_kuid_root_in_ns_with_mapping
- test_kuid_root_in_ns_with_different_mappings

Updated MAINTAINER capabilities to include commoncap test

Dan Williams ffd042a23b MAINTAINERS: notify the "Device Memory" community of memory hotplug changes
The recent episode of a warning regression in memremap_pages() [1]
highlights that relevant updates are being missed by folks that care about
core ZONE_DEVICE changes.  Yes, CXL folks should pay more attention to
linux-mm@, but it also would not hurt to copy linux-cxl@, where most
Device Memory folks hang out, on memory hotplug changes by default.

Pratyush Yadav 8de524774b MAINTAINERS: add ABI headers to KHO and LIVE UPDATE
include/linux/kho is supposed to hold KHO headers.  Add it to KHO's
MAINTAINERS entry so the right people can get patches to it.

include/linux/kho/abi contains the live update ABI headers for LUO core
and memfd.  It will also hold ABI headers for other upcoming file types as
well.  Add it to live update entry so live update maintainers can get
changes for it (currently they happen to be the same people).

Linus Torvalds dd9b004b7f tracing fixes for v6.19:
- Add Documentation/core-api/tracepoint.rst to TRACING in MAINTAINERS file
 
   Updates to the tracepoint.rst document should be reviewed by the
   tracing maintainers.
 
 - Fix warning triggered by perf attaching to synthetic events
 
   The synthetic events do not add a function to be registered when
   perf attaches to them. This causes a warning when perf registers
   a synthetic event and passes a NULL pointer to the tracepoint register
   function. Ideally synthetic events should be updated to work with
   perf, but as that's a feature and not a bug fix, simply now return
   -ENODEV when perf tries to register an event that has a NULL pointer
   for its function. This no longer causes a kernel warning and simply
   causes the perf code to fail with an error message.
 
 - Fix 32bit overflow in option flag test
 
   The option's flags changed from 32 bits in size to 64 bits in size.
   Fix one of the places that shift 1 by the option bit number to
   to be 1ULL.
 
 - Fix the output of printing the direct jmp functions
 
   The enabled_functions that shows how functions are being attached by
   ftrace wasn't updated to accommodate the new direct jmp trampolines
   that set the LSB of the pointer, and outputs garbage. Update the
   output to handle the direct jmp trampolines.

Lukas Bulwahn 09879758d8 MAINTAINERS: add tracepoint core-api doc files to TRACING
The files in Documentation/core-api/ are by virtue of their top-level
directory part of the Documentation section in MAINTAINERS. Each file in
Documentation/core-api/ should however also have a further section in
MAINTAINERS it belongs to, which fits to the technical area of the
documented API in that file.

The tracepoint.rst provides some explanation to tracepoints defined in
selected files under include/trace/events/, which itself is part of the
TRACING section.

So, add this core-api document to TRACING.

Linus Torvalds 2f7041e59b tracing fix for v6.19:
- Fix unused tracepoint build for modules only using exported tracepoints
 
   The tracepoint-update.c code that looks for unused tracepoints expects
   if tracepoints are used then it will have tracepoints defined. If
   not, it errors out which fails the build.
 
   In most cases this the way things work. A tracepoint can't be used if
   it is not defined. There is one exception; If a module only uses
   tracepoints that are defined in other modules or the vmlinux proper,
   where the tracepoints are exported. In this case, the
   tracepoint-update.c code thinks tracepoints are used but not defined
   and errors out, failing the build.
 
   When tracepoint-update.c detects this case, if it is a module that is
   being processed, exit out normally as it is a legitimate case.
 
 - Add tracepoint-update.c to MAINTAINERS file
 
   The tracepoint-update.c file is specific to tracing so add it to the
   tracing subsystem in the MAINTAINERS file.

The files in Documentation/core-api/ are by virtue of their top-level
directory part of the Documentation section in MAINTAINERS.  Each file in
Documentation/core-api/ should however also have a further section in
MAINTAINERS it belongs to, which fits to the technical area of the
documented API in that file.

idr.rst provides some explanation to the ID allocation API defined in
lib/idr.c, which itself is part of the XARRAY section.

Add this core-api document to XARRAY.

Linus Torvalds a110f94267 Pin control changes for the v6.19 kernel cycle:
Core changes:
 
 - Handle per-direction skew control in the generic pin config.
 
 - Drop the pointless subsystem boilerplate banner message during
   boot. Less noise in the console. It's available as debug message
   if someone really want it.
 
 New drivers:
 
 - Samsung Exynos 8890 SoC support.
 
 - Samsung Exynos derived Axis Communications ARTPEC-9 SoC support.
   These guys literally live next door to me, ARTPEC spells out
   "Axis Real-Time Picture Encoding Chip" and is tailored for camera
   image streams and is something they have evolved for a quarter of
   a century.
 
 - Mediatek MT6878 SoC support.
 
 - Qualcomm Glymur PMIC support (mostly just compatible strings).
 
 - Qualcomm Kaanapali SoC TLMM support.
 
 - Microchip pic64gx "gpio2" SoC support.
 
 - Microchip Polarfire "iomux0" SoC support.
 
 - CIX Semiconductors SKY1 SoC support.
 
 - Rockchip RK3506 SoC support.
 
 - Airhoa AN7583 chip support.
 
 Improvements:
 
 - Improvements for ST Microelectronics STM32 handling of skew
   settings so input and output can have different skew settings.
 
 - A whole bunch of device tree binding cleanups: Marvell Armada and
   Berlin, Actions Semiconductor S700 and S900, Broadcom Northstar 2
   (NS2), Bitmain BM1880 and Spreadtrum SC9860 are moved over to schema.

Hector Martin 49a51df427 rtc: Add new rtc-macsmc driver for Apple Silicon Macs
Apple Silicon Macs (M1, etc.) have an RTC that is part of the PMU IC,
but most of the PMU functionality is abstracted out by the SMC.
On T600x machines, the RTC counter must be accessed via the SMC to
get full functionality, and it seems likely that future machines
will move towards making SMC handle all RTC functionality.

The SMC RTC counter access is implemented on all current machines
as of the time of this writing, on firmware 12.x. However, the RTC
offset (needed to set the time) is still only accessible via direct
PMU access. To handle this, we expose the RTC offset as an NVMEM
cell from the SPMI PMU device node, and this driver consumes that
cell and uses it to compute/set the current time.

Lukas Bulwahn 40d8123ff7 MAINTAINERS: drop unneeded file entry in NVIDIA VRS RTC DRIVER
Commit 9d6d6b0693 ("rtc: nvvrs: add NVIDIA VRS RTC device driver") adds
the section NVIDIA VRS RTC DRIVER in MAINTAINERS, which refers to the
non-existing file include/linux/rtc/rtc-nvidia-vrs10.h

Note, with the changes of v6 to v7 of the patch series adding the driver,
the content of this include file was moved into the driver file, and the
include file was dropped from that patch. It was simply missed to adjust
the section in MAINTAINERS that was newly added with that patch.

Drop the file entry to this non-existing file accordingly now.

Linus Torvalds ba65a4e712 This pull request is entirely SoC clk drivers, not for lack of trying to modify
the core clk framework. The majority diff wise is for the new Rockchip and
 Qualcomm clk drivers which is mostly lines and lines of data structures to
 describe the clk hardware in these SoCs. Beyond those two, Renesas continues to
 incrementally add clks to their SoC drivers, causing them to show up higher in
 the diffstat this time because they added quite a few clks all over the place.
 Overall it is a semi-quiet release that has some new clk drivers and the usual
 fixes for clock data that was wrong or missing and non-critical cleanups that
 plug error paths or fix typos.

  - Qualcomm IPQ5424 Network Subsystem Clock Controller

Linus Torvalds b0319c4642 NFSD 6.19 Release Notes
Mike Snitzer's mechanism for disabling I/O caching introduced in
 v6.18 is extended to include using direct I/O. The goal is to
 further reduce the memory footprint consumed by NFS clients
 accessing large data sets via NFSD.
 
 The NFSD community adopted a maintainer entry profile during this
 cycle. See
 
   Documentation/filesystems/nfs/nfsd-maintainer-entry-profile.rst
 
 Work continues on hardening NFSD's implementation of the pNFS block
 layout type. This type enables pNFS clients to directly access the
 underlying block devices that contain an exported file system,
 reducing server overhead and increasing data throughput.
 
 The remaining patches in this pull request are clean-ups and minor
 optimizations. Many thanks to the contributors, reviewers, testers,
 and bug reporters who participated during the v6.19 NFSD development
 cycle.

Pull PCIe Link Encryption and Device Authentication from Dan Williams:
 "New PCI infrastructure and one architecture implementation for PCIe
  link encryption establishment via platform firmware services.

  This work is the result of multiple vendors coming to consensus on
  some core infrastructure (thanks Alexey, Yilun, and Aneesh!), and
  three vendor implementations, although only one is included in this
  pull. The PCI core changes have an ack from Bjorn, the crypto/ccp/
  changes have an ack from Tom, and the iommu/amd/ changes have an ack
  from Joerg.

  PCIe link encryption is made possible by the soup of acronyms
  mentioned in the shortlog below. Link Integrity and Data Encryption
  (IDE) is a protocol for installing keys in the transmitter and
  receiver at each end of a link. That protocol is transported over Data
  Object Exchange (DOE) mailboxes using PCI configuration requests.

  The aspect that makes this a "platform firmware service" is that the
  key provisioning and protocol is coordinated through a Trusted
  Execution Envrionment (TEE) Security Manager (TSM). That is either
  firmware running in a coprocessor (AMD SEV-TIO), or quasi-hypervisor
  software (Intel TDX Connect / ARM CCA) running in a protected CPU
  mode.

  Now, the only reason to ask a TSM to run this protocol and install the
  keys rather than have a Linux driver do the same is so that later, a
  confidential VM can ask the TSM directly "can you certify this
  device?".

  That precludes host Linux from provisioning its own keys, because host
  Linux is outside the trust domain for the VM. It also turns out that
  all architectures, save for one, do not publish a mechanism for an OS
  to establish keys in the root port. So "TSM-established link
  encryption" is the only cross-architecture path for this capability
  for the foreseeable future.

  This unblocks the other arch implementations to follow in v6.20/v7.0,
  once they clear some other dependencies, and it unblocks the next
  phase of work to implement the end-to-end flow of confidential device
  assignment. The PCIe specification calls this end-to-end flow Trusted
  Execution Environment (TEE) Device Interface Security Protocol
  (TDISP).

  In the meantime, Linux gets a link encryption facility which has
  practical benefits along the same lines as memory encryption. It
  authenticates devices via certificates and may protect against
  interposer attacks trying to capture clear-text PCIe traffic.

  Summary:

   - Introduce the PCI/TSM core for the coordination of device
     authentication, link encryption and establishment (IDE), and later
     management of the device security operational states (TDISP).
     Notify the new TSM core layer of PCI device arrival and departure

   - Add a low level TSM driver for the link encryption establishment
     capabilities of the AMD SEV-TIO architecture

   - Add a library of helpers TSM drivers to use for IDE establishment
     and the DOE transport

   - Add skeleton support for 'bind' and 'guest_request' operations in
     support of TDISP"

Linus Torvalds c84d574698 Modules changes for v6.19-rc1
Rust module parameter support:
 
 - Add Rust module parameter support, enabling Rust kernel modules to declare
   and use module parameters. The rust_minimal sample module demonstrates this,
   and the rust null block driver will be the first to use it in the next cycle.
   This also adds the Rust module files under the modules subsystem as agreed
   between the Rust and modules maintainers.
 
 Hardening:
 
 - Add compile-time check for embedded NUL characters in MODULE_*() macros. This
   module metadata was once used (and maybe still) to bypass license enforcement
   (LWN article [1] from 2003). This change required a sparse fix [2] which you
   reviewed.
 
 MAINTAINERS:
 
 - Add Aaron Tomlin as reviewer for the Modules subsystem.
 
 The changes have been in linux-next for 4 weeks. Recent 0day reports for UM [3]
 and arm64 [4] builds were not reproducible and traced to a buggy bindgen version
 combined with unreleased clang-22 in 0day. The Rust team has reported this to
 0day.
 
 As discussed previously, we rotate module maintainership among co-maintainers
 every 6 months. Sami Tolvanen is next in line and will send the next pull
 request. As a reminder, Luis has already announced [5] he will gradually step
 away as maintainer.

Pull module updates from Daniel Gomez:
 "Rust module parameter support:

   - Add Rust module parameter support, enabling Rust kernel modules to
     declare and use module parameters. The rust_minimal sample module
     demonstrates this, and the rust null block driver will be the first
     to use it in the next cycle. This also adds the Rust module files
     under the modules subsystem as agreed between the Rust and modules
     maintainers.

  Hardening:

   - Add compile-time check for embedded NUL characters in MODULE_*()
     macros. This module metadata was once used (and maybe still) to
     bypass license enforcement (LWN article from 2003):

Linus Torvalds 66a1025f7f soc: sew SoC familes for 6.19
These three new families of SoC are split out into a separate branch
 because they touch multiple parts of the source tree and are better
 left separate for the initial merge.
 
  - Black Sesame Technologies C1200 is an automotive SoC using
    Cortex-A78 CPU cores
 
  - Anlogic dr1v90 (not to be confused with Amlogic) is an FPGA
    platform using a single nuclei ux900 RISC-V core
 
  - Tenstorrent Blackhole is a Neural Processing Unit using
    custom "Tensix" cores for computation offload managed by
    Linux running on SiFive X280 RISC-V cores.
 
 Support for all three is rather rudimentary at the moment and will get
 improved as device drivers are merged through other tree.

Linus Torvalds 0cac5ce06e soc: devicetree updates for 6.19
Three new SoCs got added in existing arm64 chip families:
 
  - Renesas R-Car X5H (R8A78000) is a new generation of automotive SoCs,
    based on 16 Cortex-A720 (Armv9.2) cores, which makes the the currently
    highest-perforance embedded SoC.
 
  - TI AM62L is a new variant of the AM62 family of industrial SoCs, this
    one comes without a GPU.
 
  - Qualcomm MSM8937 (Snapdragon 430) is an older mobile phone chip based
    on Cortex-A53, and closely related to MSM8917 (Snapdragn 425), which we
    already support.
 
 In addition, there are a good number of newly supported machines
 across SoC families:
 
  - Two Aspeed AST2600 (Cortex-A7) based BMC setups for large servers
 
  - Mobile Phones and tables based on Mediatek MT6582, Nvidia Tegra124,
    Qualcomm MSM8937 and Qualcomm MSM8939,
 
  - Two Laptops based on Qualcomm SoCs: one using the older sdm850, the
    other using x1p42100.
 
  - One Router based on Rockchips RK3568
 
  - 24 variants of the Enclustra Mercury system-on-module, all based on
    32-bit Intel/Altera SocFPGA chips, plus two boards using 64-bit
    SocFPGA Agilex chips..
 
  - 30 industrial/embedded boards and single-board computers, using
    various chips from NXP, Rockchips, Mediatek, TI, Amlogic, Qualcomm,
    Spacemit, and Starfive.
 
 In total there are 783 commits here, the majority of these improving
 hardware support and cleaning up devicetree files across the tree, with
 the majority of the changes going into the Qualcomm, NXP, Renesas and
 Rockchips platforms.

   that.
 
 - The 2 patch series "make VM_SOFTDIRTY a sticky VMA flag" from Lorenzo
   Stoakes addresses the possible loss of a VMA's VM_SOFTDIRTY flag when
   that VMA is merged with another.
 
 - The 16 patch series "mm: support device-private THP" from Balbir Singh
   introduces support for Transparent Huge Page (THP) migration in zone
   device-private memory.

   split support checks" from Wei Yang provides some more cleanups in the
   folio splitting code.
 
 - The 16 patch series "mm: remove is_swap_[pte, pmd]() + non-swap
   entries, introduce leaf entries" from Lorenzo Stoakes cleans up our
   handling of pagetable leaf entries by introducing the concept of
   'software leaf entries', of type softleaf_t.
 
 - The 4 patch series "reparent the THP split queue" from Muchun Song
   reparents the THP split queue to its parent memcg.  This is in
   preparation for addressing the long-standing "dying memcg" problem,
   wherein dead memcg's linger for too long, consuming memory resources.
 
 - The 3 patch series "unify PMD scan results and remove redundant
   cleanup" from Wei Yang does a little cleanup in the hugepage collapse
   code.

 - The 4 patch series "initial work on making VMA flags a bitmap" from
   Lorenzo Stoakes starts work on converting the vma struct's flags to a
   bitmap, so we stop running out of them, especially on 32-bit.
 
 - The 2 patch series "mm/swapfile: fix and cleanup swap list iterations"
   from Youngjun Park addresses a possible bug in the swap discard code and
   cleans things up a little.

Linus Torvalds 0b1b4a3d8e Runtime verifier updates for v6.19:
- Adapt the ftracetest script to be run from a different folder
 
   This uses the already existing OPT_TEST_DIR but extends it further to run
   independent tests, then add an --rv flag to allow using the script for
   testing RV (mostly) independently on ftrace.
 
 - Add basic RV selftests in selftests/verification for more validations
 
   Add more validations for available/enabled monitors and reactors. This
   could have caught the bug introducing kernel panic solved above. Tests use
   ftracetest.
 
 - Convert react() function in reactor to use va_list directly
 
   Use a central helper to handle the variadic arguments. Clean up macros
   and mark functions as static.
 
 - Add lockdep annotations to reactors to have lockdep complain of errors
 
   If the reactors are called from improper context. Useful to develop new
   reactors. This highlights a warning in the panic reactor that is related
   to the printk subsystem and not to RV.
 
 - Convert core RV code to use lock guards and __free helpers
 
   This completely removes goto statements.
 
 - Fix compilation if !CONFIG_RV_REACTORS
 
   Fix the warning by keeping LTL monitor variable as always static.

Linus Torvalds 5779de8d36 rtla updaets for v6.19:
- Officially add Tomas Glozar as a maintainer to RTLA tool
 
 - Add for_each_monitored_cpu() helper
 
   In multiple places, RTLA tools iterate over the list of CPUs running
   tracer threads.
 
   Use single helper instead of repeating the for/if combination.
 
 - Remove unused variable option_index in argument parsing
 
   RTLA tools use getopt_long() for argument parsing. For its last
   argument, an unused variable "option_index" is passed.
 
   Remove the variable and pass NULL to getopt_long() to shorten
   the naturally long parsing functions, and make them more readable.
 
 - Fix unassigned nr_cpus after code consolidation
 
   In recent code consolidation, timerlat tool cleanup, previously
   implemented separately for each tool, was moved to a common function
   timerlat_free().
 
   The cleanup relies on nr_cpus being set. This was not done in the new
   function, leaving the variable uninitialized.
 
   Initialize the variable properly, and remove silencing of compiler
   warning for uninitialized variables.
 
 - Stop tracing on user latency in BPF mode
 
   Despite the name, rtla-timerlat's -T/--thread option sets timerlat's
   stop_tracing_total_us option, which also stops tracing on
   return-from-user latency, not only on thread latency.
 
   Implement the same behavior also in BPF sample collection stop tracing
   handler to avoid a discrepancy and restore correspondence of behavior
   with the equivalent option of cyclictest.
 
 - Fix threshold actions always triggering
 
   A bug in threshold action logic caused the action to execute even
   if tracing did not stop because of threshold.
 
   Fix the logic to stop correctly.
 
 - Fix few minor issues in tests
 
   Extend tests that were shown to need it to 5s, fix osnoise test
   calling timerlat by mistake, and use new, more reliable output
   checking in timerlat's "top stop at failed action" test.
 
 - Do not print usage on argument parsing error
 
   RTLA prints the entire usage message on encountering errors in
   argument parsing, like a malformed CPU list.
 
   The usage message has gotten too long. Instead of printing it,
   use newly added fatal() helper function to simply exit with
   the error message, excluding the usage.
 
 - Fix unintuitive -C/--cgroup interface
 
   "-C cgroup" and "--cgroup cgroup" are invalid syntax, despite that
   being a common way to specify an option with argument. Moreover,
   using them fails silently and no cgroup is set.
 
   Create new helper function to unify the handling of all such options
   and allow all of:
 
   -Xsomething
   -X=something
   -X something
 
   as well as the equivalent for the long option.
 
 - Fix -a overriding -t argument filename
 
   Fix a bug where -a following -t custom_file.txt overrides the custom
   filename with the default timerlat_trace.txt.
 
 - Stop tracing correctly on multiple events at once
 
   In some race scenarios, RTLA BPF sample collection might send multiple
   stop tracing events via the BPF ringbuffer at once.
 
   Compare the number of events for != 0 instead of == 1 to cover for
   this scenario and stop tracing properly.

Linus Torvalds ce5cfb0fa2 IOMMU Updates for Linux v6.19
Including:
 
 	- Introduction of the generic IO page-table framework with support for
 	  Intel and AMD IOMMU formats from Jason. This has good potential for
 	  unifying more IO page-table implementations and making future
 	  enhancements more easy. But this also needed quite some fixes during
 	  development. All known issues have been fixed, but my feeling is that
 	  there is a higher potential than usual that more might be needed.
 
 	- Intel VT-d updates:
 	  - Use right invalidation hint in qi_desc_iotlb().
 
 	  - Reduce the scope of INTEL_IOMMU_FLOPPY_WA.
 
 	- ARM-SMMU updates:
 	  - Qualcomm device-tree binding updates for Kaanapali and Glymur SoCs
 	    and a new clock for the TBU.
 
 	  - Fix error handling if level 1 CD table allocation fails.
 
 	  - Permit more than the architectural maximum number of SMRs for funky
 	    Qualcomm mis-implementations of SMMUv2.
 
 	- Mediatek driver:
 	  - MT8189 iommu support.
 
 	- Move ARM IO-pgtable selftests to kunit.
 
 	- Device leak fixes for a couple of drivers.
 
 	- Random smaller fixes and improvements.

Pull iommu updates from Joerg Roedel:

 - Introduction of the generic IO page-table framework with support for
   Intel and AMD IOMMU formats from Jason.

   This has good potential for unifying more IO page-table
   implementations and making future enhancements more easy. But this
   also needed quite some fixes during development. All known issues
   have been fixed, but my feeling is that there is a higher potential
   than usual that more might be needed.

 - Intel VT-d updates:
    - Use right invalidation hint in qi_desc_iotlb()
    - Reduce the scope of INTEL_IOMMU_FLOPPY_WA

 - ARM-SMMU updates:
    - Qualcomm device-tree binding updates for Kaanapali and Glymur SoCs
      and a new clock for the TBU.
    - Fix error handling if level 1 CD table allocation fails.
    - Permit more than the architectural maximum number of SMRs for
      funky Qualcomm mis-implementations of SMMUv2.

 - Mediatek driver:
    - MT8189 iommu support

 - Move ARM IO-pgtable selftests to kunit

 - Device leak fixes for a couple of drivers

 - Random smaller fixes and improvements

Pull PCI updates from Bjorn Helgaas:
 "Enumeration:

   - Enable host bridge emulation for PCI_DOMAINS_GENERIC platforms (Dan
     Williams)

   - Switch vmd from custom domain number allocator to the common
     allocator to prevent a potential race with new non-VMD buses (Dan
     Williams)

   - Enable Precision Time Measurement (PTM) only if device advertises
     support for a relevant role, to prevent invalid PTM Requests that
     cause ACS violations that are reported as AER Uncorrectable
     Non-Fatal errors (Mika Westerberg)

  Resource management:

   - Prevent resource tree corruption when BAR resize fails (Ilpo
     Järvinen)

   - Restore BARs to the original size if a BAR resize fails (Ilpo
     Järvinen)

   - Remove BAR release from BAR resize attempts by the xe, i915, and
     amdgpu drivers so the PCI core can restore BARs if the resize fails
     (Ilpo Järvinen)

   - Move Resizable BAR code to rebar.c (Ilpo Järvinen)

   - Add pci_rebar_size_supported() and use it in i915 and xe (Ilpo
     Järvinen)

   - Add pci_rebar_get_max_size() and use it in xe and amdgpu (Ilpo
     Järvinen)

  Power management and error handling:

   - For drivers using PCI legacy suspend, save config state at suspend
     so that state (not any earlier state from enumeration, probe, or
     error recovery) will be restored when resuming (Lukas Wunner)

   - For devices with no driver or a driver that lacks power management,
     save config state at hibernate so that state (not any earlier state
     from enumeration, probe, or error recovery) will be restored when
     resuming (Lukas Wunner)

   - Save device config space on device addition, before driver binding,
     so error recovery works more reliably (Lukas Wunner)

   - Drop pci_save_state() from several drivers that no longer need it
     since the PCI core always does it and pci_restore_state() no longer
     invalidates the saved state (Lukas Wunner)

   - Document use of pci_save_state() by drivers to capture the state
     they want restored during error recovery (Lukas Wunner)

  Power control:

   - Add a struct pci_ops.assert_perst() function pointer to
     assert/deassert PCIe PERST# and implement it for the qcom driver
     (Krishna Chaitanya Chundru)

   - Add DT binding and pwrctrl driver for the Toshiba TC9563 PCIe
     switch, which must be held in reset after poweron so the pwrctrl
     driver can configure the switch via I2C before bringing up the
     links (Krishna Chaitanya Chundru)

  Endpoint framework:

   - Convert the endpoint doorbell test to use a threaded IRQ to fix a
     'sleeping while atomic' issue (Bhanu Seshu Kumar Valluri)

   - Add endpoint VNTB MSI doorbell support to reduce latency between
     host and endpoint (Frank Li)

  New native PCIe controller drivers:

   - Add CIX Sky1 host controller DT binding and driver (Hans Zhang)

   - Add NXP S32G host controller DT binding and driver (Vincent
     Guittot)

   - Add Renesas RZ/G3S host controller DT binding and driver (Claudiu
     Beznea)

   - Add SpacemiT K1 host controller DT binding and driver (Alex Elder)

  Amlogic Meson PCIe controller driver:

   - Update DT binding to name DBI region 'dbi', not 'elbi', and update
     driver to support both (Manivannan Sadhasivam)

  Apple PCIe controller driver:

   - Move struct pci_host_bridge allocation from pci_host_common_init()
     to callers, which significantly simplifies pcie-apple (Marc
     Zyngier)

  Broadcom STB PCIe controller driver:

   - Disable advertising ASPM L0s support correctly (Jim Quinlan)

   - Add a panic/die handler to print diagnostic info in case PCIe
     caused an unrecoverable abort (Jim Quinlan)

  Cadence PCIe controller driver:

   - Add module support for Cadence platform host and endpoint
     controller driver (Manikandan K Pillai)

   - Split headers into 'legacy' (LGA) and 'high perf' (HPA) to prepare
     for new CIX Sky1 driver (Manikandan K Pillai)

  MediaTek PCIe controller driver:

   - Convert DT binding to YAML schema (Christian Marangi)

   - Add Airoha AN7583 DT compatible and driver support (Christian
     Marangi)

  Qualcomm PCIe controller driver:

   - Add Qualcomm Kaanapali to SM8550 DT binding (Qiang Yu)

   - Add required 'power-domains' and 'resets' to qcom sa8775p, sc7280,
     sc8280xp, sm8150, sm8250, sm8350, sm8450, sm8550, x1e80100 DT
     schemas (Krzysztof Kozlowski)

   - Look up OPP using both frequency and data rate (not just frequency)
     so RPMh votes can account for both (Krishna Chaitanya Chundru)

  Rockchip DesignWare PCIe controller driver:

   - Add Rockchip RK3528 compatible strings in DT binding (Yao Zi)

  STMicroelectronics STM32MP25 PCIe controller driver:

   - Fix a race between link training and endpoint register
     initialization (Christian Bruel)

   - Align endpoint allocations to match the ATU requirements (Christian
     Bruel)

  Synopsys DesignWare PCIe controller driver:

   - Clear L1 PM Substate Capability 'Supported' bits unless glue driver
     says it's supported, which prevents users from enabling non-working
     L1SS. Currently only qcom and tegra194 support L1SS (Bjorn Helgaas)

   - Remove now-superfluous L1SS disable code from tegra194 (Bjorn
     Helgaas)

   - Configure L1SS support in dw-rockchip when DT says
     'supports-clkreq' (Shawn Lin)

  TI Keystone PCIe controller driver:

   - Fail the probe instead of silently succeeding if ks_pcie_of_data
     didn't specify Root Complex or Endpoint mode (Siddharth Vadapalli)

   - Make keystone buildable as a loadable module, except on ARM32 where
     hook_fault_code() is __init (Siddharth Vadapalli)"
