Pull non-MM updates from Andrew Morton:

 - "ocfs2: exit recovery thread on mount error path" (Joseph Qi):

   Stop OCFS2 recovery before freeing failed-mount state and replay
   slots, closing use-after-free and double-free races. Defer
   suballocator reclaim to break a transaction-lock deadlock with
   dismount.

 - "ocfs2: validate suballoc slot and bit of metadata blocks" (Joseph
   Qi):

   Validate OCFS2 metadata suballocator slots, bits and directory index
   block locations. Reject corrupt metadata with filesystem errors
   instead of BUGs or out-of-bounds accesses.

 - "ocfs2: deal with legacy signed name hash values" (Joseph Qi):

   Restore OCFS2 lookups for non-ASCII names stored with legacy signed
   hashes. Use stored xattr hashes during bucket splits to avoid
   duplicate entries and spurious ENOSPC failures.

 - "ocfs2: stabilize dentry names in file and setattr traces" (Cen
   Zhang):

   Snapshot OCFS2 names during file and setattr tracing to prevent
   rename races using freed storage or mismatched names and lengths.
   Preserve trace formats and the locked release open-count sample.

 - "panic: fix panic_force_cpu= redirect races and NMI bypass" (Bradley
   Morgan):

   Fix panic_force_cpu races and NMI redirection so crash-kernel CPU
   selection is honored. Preserve variable arguments on failed redirects
   and use a static message buffer.

 - "fat: allocate multiple clusters in fallocate" (Matheus Alves de
   Almeida):

   Allocate FAT clusters in batches for FALLOC_FL_KEEP_SIZE and batch
   FAT updates. This removes repeated single-cluster allocation
   overhead, particularly on synchronous mounts.

 - "scripts/gdb: fix radix tree lookup and stack depot diagnostic"
   (Ting-Han Hou):

   Fix GDB radix-tree lookup and its handling of XArray sibling, retry
   and zero entries. Also repair the stack-depot diagnostic for an
   out-of-range pool index.

 - "hung_task: Improve warning budget handling and task reporting"
   (Aaron Tomlin):

   Reset the hung-task warning budget after recovery so later hangs
   remain visible. Keep the configured limit intact and emit one summary
   per scan when detailed reports exhaust the budget.

 - "bootconfig: Reject unexpected data after null character and
   cleanups" (Masami Hiramatsu):

   Reject bootconfig data after an embedded null while accepting
   trailing padding. Validate the full input in the userspace tool, and
   retain internal tree sanity checks there rather than in the kernel.

 - "kbuild: GCOV cleanups following the prefer-atomic fix" (Konstantin
   Khorenko):

   Use the actual GCOV build flags in the prefer-atomic compiler probe.
   Move flag setup into scripts/Makefile.gcov and skip the probe when
   GCOV is disabled.

 - "ocfs2: xattr bucket validation fixes" (Joseph Qi):

   Accept valid OCFS2 xattr buckets spanning 512-byte blocks, avoiding
   false read-only remounts. Reject misaligned buckets and return errors
   instead of panicking on corrupt defrag metadata.

 - "ocfs2: fix metadata reservation for xattr value trees" (Joseph Qi):

   Reserve enough OCFS2 metadata for new and relocated xattr value
   trees. Fix shortfalls which could cause ENOSPC, dropped entries and
   leaked clusters on fragmented filesystems; remove duplicate
   reservations.

 - "Introduce arch_do_panic" (Mete Durlu):

   Add arch_do_panic() and move s390 and sparc handling out of generic
   panic code. The architecture-specific actions now follow the
   end-of-panic marker.

 - "checkpatch: userspace improvements" (Petr Vorel):

   Improve checkpatch's userspace detection and suppress kernel-only
   checks. Recognize standard inttypes macros and add explicit
   --userspace and --no-userspace overrides.

 - "ocfs2: validate dr_fs_generation of dir index root blocks" (Joseph
   Qi):

   Check OCFS2 directory index generations and leaf block numbers.
   Reject stale or misplaced blocks instead of using metadata left by a
   previously formatted filesystem.

 - "selftests/membarrier: Skip an unregistered memory barrier test on
   Musl" (Chris Gellermann):

   Skip the unregistered membarrier test when libc has already
   registered the command. Musl does this during thread creation,
   causing false failures in the multithreaded test.

 - "init: fix array boundary bugs in boot parameter parsing"
   (Wilson Felipe Pereira):

   Fix boot argument boundary cases which leave stale arguments in
   init's command line or panic when replacing the final environment
   variable. Clear the last slot and check duplicates before the limit.

Summary of the 87 singletons in this merge:

  The OCFS2 singletons fix deadlocks between xattr updates and inline
  truncation, and during inode reclaim. Corrupt quota and extent
  metadata could also crash the kernel or corrupt memory; these paths
  now check the layout before using it. Other fixes close use-after-free
  and publication races around cluster reconfiguration, node failure,
  quota remount errors and shared refcount trees. New files now retain
  security labels from all stacked LSMs instead of silently dropping all
  but one. Valid xattr insertions also stop tripping FORTIFY on builds
  with counted arrays.

  Elsewhere, a lost wakeup could leave hardware-monitoring reads stuck
  in unkillable sleep and block further I2C traffic. That is fixed, as
  are kernel memory leaks in POSIX message-queue notifications and tmpfs
  casefold setup which could grow until memory is exhausted. A driver
  removal race which could crash the kernel is fixed too. The
  hibernation command through reboot() also stops taking the same mutex
  twice, avoiding a deadlock before suspension.

  On the boot side, bzip2 decoding now accepts valid full blocks emitted
  by lbzip2, fixing failures to boot those compressed kernels. Malformed
  bzip2 streams can no longer overflow the decode buffer, and LZ4
  initrds are checked before the decoder can read past their end. FAT
  rejects geometry which overflows the data-area calculation on 32-bit
  systems, and rolls back entries when inode setup fails, preventing
  failed creations from reappearing after remount. The x86 XOR and RAID6
  AVX paths also avoid imposing a slowdown on subsequent SSE code.

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.
