50ac57c3b1 Merge tag 'x86_tdx_for_6.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip 
Pull x86 TDX updates from Dave Hansen:
 "The biggest change here is making TDX and kexec play nicely together.

  Before this, the memory encryption hardware (which doesn't respect
  cache coherency) could write back old cachelines on top of data in the
  new kernel, so kexec and TDX were made mutually exclusive. This
  removes the limitation.

  There is also some work to tighten up a hardware bug workaround and
  some MAINTAINERS updates.

   - Make TDX and kexec work together

    - Skip TDX bug workaround when the bug is not present

    - Update maintainers entries"

f3826aa996 Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm 
Pull kvm updates from Paolo Bonzini:
 "This excludes the bulk of the x86 changes, which I will send
  separately. They have two not complex but relatively unusual conflicts
  so I will wait for other dust to settle.

  guest_memfd:

   - Add support for host userspace mapping of guest_memfd-backed memory
     for VM types that do NOT use support KVM_MEMORY_ATTRIBUTE_PRIVATE
     (which isn't precisely the same thing as CoCo VMs, since x86's
     SEV-MEM and SEV-ES have no way to detect private vs. shared).

     This lays the groundwork for removal of guest memory from the
     kernel direct map, as well as for limited mmap() for
     guest_memfd-backed memory.

     For more information see:
       - commit a6ad54137a ("Merge branch 'guest-memfd-mmap' into HEAD")
       - guest_memfd in Firecracker:
           https://github.com/firecracker-microvm/firecracker/tree/feature/secret-hiding
       - direct map removal:
           https://lore.kernel.org/all/20250221160728.1584559-1-roypat@amazon.co.uk/
       - mmap support:
           https://lore.kernel.org/all/20250328153133.3504118-1-tabba@google.com/

  ARM:

   - Add support for FF-A 1.2 as the secure memory conduit for pKVM,
     allowing more registers to be used as part of the message payload.

   - Change the way pKVM allocates its VM handles, making sure that the
     privileged hypervisor is never tricked into using uninitialised
     data.

   - Speed up MMIO range registration by avoiding unnecessary RCU
     synchronisation, which results in VMs starting much quicker.

   - Add the dump of the instruction stream when panic-ing in the EL2
     payload, just like the rest of the kernel has always done. This
     will hopefully help debugging non-VHE setups.

   - Add 52bit PA support to the stage-1 page-table walker, and make use
     of it to populate the fault level reported to the guest on failing
     to translate a stage-1 walk.

   - Add NV support to the GICv3-on-GICv5 emulation code, ensuring
     feature parity for guests, irrespective of the host platform.

   - Fix some really ugly architecture problems when dealing with debug
     in a nested VM. This has some bad performance impacts, but is at
     least correct.

   - Add enough infrastructure to be able to disable EL2 features and
     give effective values to the EL2 control registers. This then
     allows a bunch of features to be turned off, which helps cross-host
     migration.

   - Large rework of the selftest infrastructure to allow most tests to
     transparently run at EL2. This is the first step towards enabling
     NV testing.

   - Various fixes and improvements all over the map, including one BE
     fix, just in time for the removal of the feature.

  LoongArch:

   - Detect page table walk feature on new hardware

   - Add sign extension with kernel MMIO/IOCSR emulation

   - Improve in-kernel IPI emulation

   - Improve in-kernel PCH-PIC emulation

   - Move kvm_iocsr tracepoint out of generic code

  RISC-V:

   - Added SBI FWFT extension for Guest/VM with misaligned delegation
     and pointer masking PMLEN features

   - Added ONE_REG interface for SBI FWFT extension

   - Added Zicbop and bfloat16 extensions for Guest/VM

   - Enabled more common KVM selftests for RISC-V

   - Added SBI v3.0 PMU enhancements in KVM and perf driver

  s390:

   - Improve interrupt cpu for wakeup, in particular the heuristic to
     decide which vCPU to deliver a floating interrupt to.

   - Clear the PTE when discarding a swapped page because of CMMA; this
     bug was introduced in 6.16 when refactoring gmap code.

  x86 selftests:

   - Add #DE coverage in the fastops test (the only exception that's
     guest- triggerable in fastop-emulated instructions).

   - Fix PMU selftests errors encountered on Granite Rapids (GNR),
     Sierra Forest (SRF) and Clearwater Forest (CWF).

   - Minor cleanups and improvements

  x86 (guest side):

   - For the legacy PCI hole (memory between TOLUD and 4GiB) to UC when
     overriding guest MTRR for TDX/SNP to fix an issue where ACPI
     auto-mapping could map devices as WB and prevent the device drivers
     from mapping their devices with UC/UC-.

   - Make kvm_async_pf_task_wake() a local static helper and remove its
     export.

   - Use native qspinlocks when running in a VM with dedicated
     vCPU=>pCPU bindings even when PV_UNHALT is unsupported.

  Generic:

   - Remove a redundant __GFP_NOWARN from kvm_setup_async_pf() as
     __GFP_NOWARN is now included in GFP_NOWAIT.

99fd09e01d dt-bindings: i2c: realtek,rtl9301-i2c: extend for RTL9310 support 
Adjust the regex for child-node address to account for the fact that
RTL9310 supports 12 instead of only 8 SDA lines. Also, narrow this per
variant.

Add a vendor-specific property to explicitly specify the SCL line number
of the defined I2C controller/master. This is required, in particular
for RTL9310, to operate on the correct SCL for each controller. Require
this property to be specified for RTL9310.

Add compatibles for known SoC variants RTL9311, RTL9312 and RTL9313.

Pull dma-mapping updates from Marek Szyprowski:

 - Refactoring of DMA mapping API to physical addresses as the primary
   interface instead of page+offset parameters

   This gets much closer to Matthew Wilcox's long term wish for
   struct-pageless IO to cacheable DRAM and is supporting memdesc
   project which seeks to substantially transform how struct page works.

   An advantage of this approach is the possibility of introducing
   DMA_ATTR_MMIO, which covers existing 'dma_map_resource' flow in the
   common paths, what in turn lets to use recently introduced
   dma_iova_link() API to map PCI P2P MMIO without creating struct page

86d563ac5f Merge tag 'f2fs-for-6.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs 
Pull f2fs updates from Jaegeuk Kim:
 "This focuses on two primary updates for Android devices.

  First, it sets hash-based file name lookup as the default method to
  improve performance, while retaining an option to fall back to a
  linear lookup.

  Second, it resolves a persistent issue with the 'checkpoint=enable'
  feature.

  The update further boosts performance by prefetching node blocks,
  merging FUA writes more efficiently, and optimizing block allocation
  policies.

  The release is rounded out by a comprehensive set of bug fixes that
  address memory safety, data integrity, and potential system hangs,
  along with minor documentation and code clean-ups.

  Enhancements:
   - add mount option and sysfs entry to tune the lookup mode
   - dump more information and add a timeout when enabling/disabling
     checkpoints
   - readahead node blocks in F2FS_GET_BLOCK_PRECACHE mode
   - merge FUA command with the existing writes
   - allocate HOT_DATA for IPU writes
   - Use allocate_section_policy to control write priority in
     multi-devices setups
   - add reserved nodes for privileged users
   - Add bggc_io_aware to adjust the priority of BG_GC when issuing IO
   - show the list of donation files

  Bug fixes:
   - add missing dput() when printing the donation list
   - fix UAF issue in f2fs_merge_page_bio()
   - add sanity check on ei.len in __update_extent_tree_range()
   - fix infinite loop in __insert_extent_tree()
   - fix zero-sized extent for precache extents
   - fix to mitigate overhead of f2fs_zero_post_eof_page()
   - fix to avoid migrating empty section
   - fix to truncate first page in error path of f2fs_truncate()
   - fix to update map->m_next_extent correctly in f2fs_map_blocks()
   - fix wrong layout information on 16KB page
   - fix to do sanity check on node footer for non inode dnode
   - fix to avoid NULL pointer dereference in
     f2fs_check_quota_consistency()
   - fix to detect potential corrupted nid in free_nid_list
   - fix to clear unusable_cap for checkpoint=enable
   - fix to zero data after EOF for compressed file correctly
   - fix to avoid overflow while left shift operation
   - fix condition in __allow_reserved_blocks()"

Pull networking updates from Paolo Abeni:
 "Core & protocols:

   - Improve drop account scalability on NUMA hosts for RAW and UDP
     sockets and the backlog, almost doubling the Pps capacity under DoS

   - Optimize the UDP RX performance under stress, reducing contention,
     revisiting the binary layout of the involved data structs and
     implementing NUMA-aware locking. This improves UDP RX performance
     by an additional 50%, even more under extreme conditions

   - Add support for PSP encryption of TCP connections; this mechanism
     has some similarities with IPsec and TLS, but offers superior HW
     offloads capabilities

   - Ongoing work to support Accurate ECN for TCP. AccECN allows more
     than one congestion notification signal per RTT and is a building
     block for Low Latency, Low Loss, and Scalable Throughput (L4S)

   - Reorganize the TCP socket binary layout for data locality, reducing
     the number of touched cachelines in the fastpath

   - Refactor skb deferral free to better scale on large multi-NUMA
     hosts, this improves TCP and UDP RX performances significantly on
     such HW

   - Increase the default socket memory buffer limits from 256K to 4M to
     better fit modern link speeds

   - Improve handling of setups with a large number of nexthop, making
     dump operating scaling linearly and avoiding unneeded
     synchronize_rcu() on delete

   - Improve bridge handling of VLAN FDB, storing a single entry per
     bridge instead of one entry per port; this makes the dump order of
     magnitude faster on large switches

   - Restore IP ID correctly for encapsulated packets at GSO
     segmentation time, allowing GRO to merge packets in more scenarios

   - Improve netfilter matching performance on large sets

   - Improve MPTCP receive path performance by leveraging recently
     introduced core infrastructure (skb deferral free) and adopting
     recent TCP autotuning changes

   - Allow bridges to redirect to a backup port when the bridge port is
     administratively down

   - Introduce MPTCP 'laminar' endpoint that con be used only once per
     connection and simplify common MPTCP setups

   - Add RCU safety to dst->dev, closing a lot of possible races

   - A significant crypto library API for SCTP, MPTCP and IPv6 SR,
     reducing code duplication

   - Supports pulling data from an skb frag into the linear area of an
     XDP buffer

  Things we sprinkled into general kernel code:

   - Generate netlink documentation from YAML using an integrated YAML
     parser

  Driver API:

   - Support using IPv6 Flow Label in Rx hash computation and RSS queue
     selection

   - Introduce API for fetching the DMA device for a given queue,
     allowing TCP zerocopy RX on more H/W setups

   - Make XDP helpers compatible with unreadable memory, allowing more
     easily building DevMem-enabled drivers with a unified XDP/skbs
     datapath

   - Add a new dedicated ethtool callback enabling drivers to provide
     the number of RX rings directly, improving efficiency and clarity
     in RX ring queries and RSS configuration

   - Introduce a burst period for the health reporter, allowing better
     handling of multiple errors due to the same root cause

   - Support for DPLL phase offset exponential moving average,
     controlling the average smoothing factor

  Device drivers:

   - Add a new Huawei driver for 3rd gen NIC (hinic3)

   - Add a new SpacemiT driver for K1 ethernet MAC

           SR-IOV VFs to sibling PFs
         - support RSS for IPSec offload
         - support exposing raw cycle counters in PTP and mlx5
         - support for disabling host PFs.

Pull sound updates from Takashi Iwai:
 "It's been relatively calm in this cycle from the feature POV, but
  there were lots of cleanup works in the wide-range of code for
  converting with the auto-cleanup macros like guard().

  The mostly user-visible changes are the support of a couple of new
  compress-offload API extensions, and the support of new ASoC codec /
  platform drivers as well as USB-audio quirks.

  Here we go with some highlights:

  Core:
   - Compress-offload API extension for 64bit timestamp support
   - Compress-offload API extension for OPUS codec support
   - Workaround for PCM locking issue with PREEMPT_RT and softirq
   - KCSAN warning fix for ALSA sequencer core

  ASoC:
   - Continued cleanup works for ASoC core APIs
   - Lots of cleanups and conversions of DT bindings
   - Substantial maintainance work on the Intel AVS drivers
   - Support for Qualcomm Glymur and PM4125, Realtek RT1321, Shanghai
     FourSemi FS2104/5S, Texas Instruments PCM1754 and TAS2783A
   - Remove support for TI WL1273 for old Nokia systems

  USB-audio:
   - Support for Tascam US-144mkII, Presonus S1824c support
   - More flexible quirk option handling
   - Fix for USB MIDI timer bug triggered by fuzzer

  Others:
   - A large series of cleanups with guard() & co macros over (non-ASoC)
     sound drivers (PCI, ISA, HD-audio, USB-audio, drivers, etc)
   - TAS5825 HD-audio side-codec support"

 - MD pull request via Yu:
     - Add support for a lockless bitmap.

       A key feature for the new bitmap are that the IO fastpath is
       lockless. If a user issues lots of write IO to the same bitmap
       bit in a short time, only the first write has additional overhead
       to update bitmap bit, no additional overhead for the following
       writes.

       By supporting only resync or recover written data, means in the
       case creating new array or replacing with a new disk, there is no
       need to do a full disk resync/recovery.

 - Switch ->getgeo() and ->bios_param() to using struct gendisk rather
   than struct block_device.

 - Rust block changes via Andreas. This series adds configuration via
   configfs and remote completion to the rnull driver. The series also
   includes a set of changes to the rust block device driver API: a few
   cleanup patches, and a few features supporting the rnull changes.

   The series removes the raw buffer formatting logic from
   `kernel::block` and improves the logic available in `kernel::string`
   to support the same use as the removed logic.

 - floppy arch cleanups

 - Reduce the number of dereferencing needed for ublk commands

 - Restrict supported sockets for nbd. Mostly done to eliminate a class
   of issues perpetually reported by syzbot, by using nonsensical socket
   setups.

 - A few s390 dasd block fixes

 - Fix a few issues around atomic writes

 - Improve DMA interation for integrity requests

 - Improve how iovecs are treated with regards to O_DIRECT aligment
   constraints.

   We used to require each segment to adhere to the constraints, now
   only the request as a whole needs to.

 - Clean up and improve p2p support, enabling use of p2p for metadata
   payloads

 - Improve locking of request lookup, using SRCU where appropriate

 - Use page references properly for brd, avoiding very long RCU sections

 - Fix ordering of recursively submitted IOs

Pull io_uring updates from Jens Axboe:

 - Store ring provided buffers locally for the users, rather than stuff
   them into struct io_kiocb.

   These types of buffers must always be fully consumed or recycled in
   the current context, and leaving them in struct io_kiocb is hence not
   a good ideas as that struct has a vastly different life time.

   Basically just an architecture cleanup that can help prevent issues
   with ring provided buffers in the future.

 - Support for mixed CQE sizes in the same ring.

   Before this change, a CQ ring either used the default 16b CQEs, or it
   was setup with 32b CQE using IORING_SETUP_CQE32. For use cases where
   a few 32b CQEs were needed, this caused everything else to use big
   CQEs. This is wasteful both in terms of memory usage, but also memory
   bandwidth for the posted CQEs.

   With IORING_SETUP_CQE_MIXED, applications may use request types that
   post both normal 16b and big 32b CQEs on the same ring.

 - Add helpers for async data management, to make it harder for opcode
   handlers to mess it up.

 - Add support for multishot for uring_cmd, which ublk can use. This
   helps improve efficiency, by providing a persistent request type that
   can trigger multiple CQEs.

 - Add initial support for ring feature querying.

   We had basic support for probe operations, but the API isn't great.
   Rather than expand that, add support for QUERY which is easily
   expandable and can cover a lot more cases than the existing probe
   support. This will help applications get a better idea of what
   operations are supported on a given host.

 - zcrx improvements from Pavel:
        - Improve refill entry alignment for better caching
        - Various cleanups, especially around deduplicating normal
          memory vs dmabuf setup.
        - Generalisation of the niov size (Patch 12). It's still hard
          coded to PAGE_SIZE on init, but will let the user to specify
          the rx buffer length on setup.
        - Syscall / synchronous bufer return. It'll be used as a slow
          fallback path for returning buffers when the refill queue is
          full. Useful for tolerating slight queue size misconfiguration
          or with inconsistent load.
        - Accounting more memory to cgroups.
        - Additional independent cleanups that will also be useful for
          mutli-area support.

4092fc5f35 spi: dt-bindings: cadence: add soc-specific compatible strings for zynqmp and versal-net 
When the binding for the Cadence spi controller was written, a dedicated
compatible was added for the zynq device. Later when zynqmp and
versal-net, which also use this spi controller IP, were added they did
not receive soc-specific compatibles. Add them now, with a fallback to
the existing compatible for the r1p6 version of the IP so that there
will be no functional change. Retain the r1p6 in the string, to match
what was done for zynq.

Disallow the cdns,spi-r1p6 compatible in isolation to "encourage" people
to actually add soc-specific compatible strings in the future.

Pull kunit updates from Shuah Khan:

 - New parameterized test features

   KUnit parameterized tests supported two primary methods for getting
   parameters:

    - Defining custom logic within a generate_params() function.

    - Using the KUNIT_ARRAY_PARAM() and KUNIT_ARRAY_PARAM_DESC() macros
      with a pre-defined static array and passing the created
      *_gen_params() to KUNIT_CASE_PARAM().

   These methods present limitations when dealing with dynamically
   generated parameter arrays, or in scenarios where populating
   parameters sequentially via generate_params() is inefficient or
   overly complex.

   These limitations are fixed with a parameterized test method

   - Apple M2 Pro, M2 Max and M2 Ultra, used in the 2022/2023 generation
     of high-end workstations and laptops from Apple. Linux has been
     working on these for a while but stil requires patches.

   - Axis Artpec8 is an Armv8 chip based on Samsung Exynos design,
     unlike the earlier Armv7 Artpec6 from the same company that was
     part of a separate family of chips.

   - NXP i.MX91 is a cut-down version of i.MX93, using only a single
     Cortex-A55 core.

   - Qualcomm Lemans Auto is a variant of the Lemans SoC that was
     originally merged under the sa8775p name, the differences being
     mostly the firmware configuration of the platform.

   - Four new Renesas SoCs RZ/T2H (r9a09g077m44), RZ/N2H (r9a09g087m44),
     RZ/T2H (r9a09g077), and RZ/N2H (r9a09g087) are all industrial

  In total, there are 65 new machines, including:

   - Industrial embedded system and single-board computers based on NXP,
     Allwinner, TI, Rockchips, Marvell, Xilinx Spacemit, Starfive chips.

   - Reference boards for the newly added Renesas, Qualcomm, NXP and

   - Laptops and Workstations using Apple M2 and Qualcomm Snapdragon X1
     chips.

   - Several Samsung phones using Qualcomm Snapdragon chips

   - Set-top boxes based on Allwinner H313

   - Five BMC boards using 32-bit ASpeed SoCs

   - Three network routers using IXP4xx (ARMv5!) and Broadcom bcm4708
     (ARMv7) SoCs

  Two machines get phased out because they were available only in small
  quantities but never made it into products: one STi407 based reference
  board, and a Snapdragon 845 based Chromebook.

  Aside from the newly added machines, a lot of work went into improving

Pull pin control updates from Linus Walleij:
 "We have GPIO awareness in the pin control core and an interesting
  AAEON driver.

  Core changes:

   - Allow pins to be identified/marked as GPIO mode with a special
     callback.

     The pin controller core is now "aware" if a pin is in GPIO mode if
     the callback is implemented in the driver, and can thus be marked
     as "strict", i.e. disallowing simultaneous use of a line as GPIO
     and another function such as I2C.

     This is enabled in the Qualcomm TLMM driver and also implemeted
     from day 1 in the new Broadcom STB driver

   - Rename the pin config option PIN_CONFIG_OUTPUT to PIN_CONFIG_LEVEL
     to better describe what the config is doing, as well as making it
     more intuitive what shall be returned when reading this property

  New drivers:

   - Qualcomm SDM660 LPASS LPI TLMM pin controller subdriver

   - Qualcomm Glymur family pin controller driver

   - Broadcom STB family pin controller driver

   - Tegra186 pin controller driver

   - AAEON UP pin controller support.

     This is some special pin controller that works as an external
     advanced line MUX and amplifier for signals from an Intel SoC. A
     cooperative effort with the GPIO maintainer was needed to reach a
     solution where we reuse code from the GPIO aggregator/forwarder
     driver

   - Renesas RZ/T2H and RZ/N2H pin controller support

   - Axis ARTPEC-8 subdriver for the Samsung pin controller driver

  Improvements:

   - Output enable (OEN) support in the Renesas RZG2L driver

   - Properly support bias pull up/down in the pinctrl-single driver

   - Move over all GPIO portions using generic MMIO GPIO to the new
     generic GPIO chip management which has a nice and separate API

   - Proper DT bindings for some older Broadcom SoCs

   - External GPIO (EGPIO) support in the Qualcomm SM8250

  Deleted code:

   - Dropped the now unused Samsung S3C24xx drivers"

     been very good. After working with some people on this, the code
