a720270452 wifi: ath12k: Modularize driver into common and Wi-Fi 7 specific components 
Split the ath12k driver into two kernel modules:

 - ath12k.ko for shared logic across multiple targets
 - ath12k_wifi7.ko for Wi-Fi 7 specific configuration and routines

The common module (ath12k.ko) must be loaded prior to any device-specific
module, as the latter depends on exported symbols from the former.

As part of this restructuring, Wi-Fi 7 specific files are moved into a
dedicated `wifi7/` directory and built as a separate module. Common
symbols are exported accordingly, with further adjustments planned
in upcoming patches to support architecture-dependent separation.

This modularization improves maintainability and scalability by enabling
clean separation of hardware-specific logic from the shared driver core.

8be4d31cb8 Networking changes for 6.17. 
Core & protocols
 ----------------
 
  - Wrap datapath globals into net_aligned_data, to avoid false sharing.
 
  - Preserve MSG_ZEROCOPY in forwarding (e.g. out of a container).
 
  - Add SO_INQ and SCM_INQ support to AF_UNIX.
 
  - Add SIOCINQ support to AF_VSOCK.
 
  - Add TCP_MAXSEG sockopt to MPTCP.
 
  - Add IPv6 force_forwarding sysctl to enable forwarding per interface.
 
  - Make TCP validation of whether packet fully fits in the receive
    window and the rcv_buf more strict. With increased use of HW
    aggregation a single "packet" can be multiple 100s of kB.
 
  - Add MSG_MORE flag to optimize large TCP transmissions via sockmap,
    improves latency up to 33% for sockmap users.
 
  - Convert TCP send queue handling from tasklet to BH workque.
 
  - Improve BPF iteration over TCP sockets to see each socket exactly once.
 
  - Remove obsolete and unused TCP RFC3517/RFC6675 loss recovery code.
 
  - Support enabling kernel threads for NAPI processing on per-NAPI
    instance basis rather than a whole device. Fully stop the kernel NAPI
    thread when threaded NAPI gets disabled. Previously thread would stick
    around until ifdown due to tricky synchronization.
 
  - Allow multicast routing to take effect on locally-generated packets.
 
  - Add output interface argument for End.X in segment routing.
 
  - MCTP: add support for gateway routing, improve bind() handling.
 
  - Don't require rtnl_lock when fetching an IPv6 neighbor over Netlink.
 
  - Add a new neighbor flag ("extern_valid"), which cedes refresh
    responsibilities to userspace. This is needed for EVPN multi-homing
    where a neighbor entry for a multi-homed host needs to be synced
    across all the VTEPs among which the host is multi-homed.
 
  - Support NUD_PERMANENT for proxy neighbor entries.
 
  - Add a new queuing discipline for IETF RFC9332 DualQ Coupled AQM.
 
  - Add sequence numbers to netconsole messages. Unregister netconsole's
    console when all net targets are removed. Code refactoring.
    Add a number of selftests.
 
  - Align IPSec inbound SA lookup to RFC 4301. Only SPI and protocol
    should be used for an inbound SA lookup.
 
  - Support inspecting ref_tracker state via DebugFS.
 
  - Don't force bonding advertisement frames tx to ~333 ms boundaries.
    Add broadcast_neighbor option to send ARP/ND on all bonded links.
 
  - Allow providing upcall pid for the 'execute' command in openvswitch.
 
  - Remove DCCP support from Netfilter's conntrack.
 
  - Disallow multiple packet duplications in the queuing layer.
 
  - Prevent use of deprecated iptables code on PREEMPT_RT.
 
 Driver API
 ----------
 
  - Support RSS and hashing configuration over ethtool Netlink.
 
  - Add dedicated ethtool callbacks for getting and setting hashing fields.
 
  - Add support for power budget evaluation strategy in PSE /
    Power-over-Ethernet. Generate Netlink events for overcurrent etc.
 
  - Support DPLL phase offset monitoring across all device inputs.
    Support providing clock reference and SYNC over separate DPLL
    inputs.
 
  - Support traffic classes in devlink rate API for bandwidth management.
 
  - Remove rtnl_lock dependency from UDP tunnel port configuration.

4b290aae78 Summary 
* Move sysctls out of the kern_table array
 
   This is the final move of ctl_tables into their respective subsystems. Only 5
   (out of the original 50) will remain in kernel/sysctl.c file; these handle
   either sysctl or common arch variables.
 
   By decentralizing sysctl registrations, subsystem maintainers regain control
   over their sysctl interfaces, improving maintainability and reducing the
   likelihood of merge conflicts.
 
 * docs: Remove false positives from check-sysctl-docs
 
   Stopped falsely identifying sysctls as undocumented or unimplemented in the
   check-sysctl-docs script. This script can now be used to automatically
   identify if documentation is missing.
 
 * Testing
 
   All these have been in linux-next since rc3, giving them a solid 3 to 4 weeks
   worth of testing. Additionally, sysctl selftests and kunit were also run
   locally on my x86_64

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

Pull arm64 updates from Catalin Marinas:
 "A quick summary: perf support for Branch Record Buffer Extensions
  (BRBE), typical PMU hardware updates, small additions to MTE for
  store-only tag checking and exposing non-address bits to signal
  handlers, HAVE_LIVEPATCH enabled on arm64, VMAP_STACK forced on.

  There is also a TLBI optimisation on hardware that does not require
  break-before-make when changing the user PTEs between contiguous and
  non-contiguous.

  More details:

  Perf and PMU updates:

   - Add support for new (v3) Hisilicon SLLC and DDRC PMUs

   - Add support for Arm-NI PMU integrations that share interrupts
     between clock domains within a given instance

   - Allow SPE to be configured with a lower sample period than the
     minimum recommendation advertised by PMSIDR_EL1.Interval

   - Add suppport for Arm's "Branch Record Buffer Extension" (BRBE)

   - Adjust the perf watchdog period according to cpu frequency changes

   - Minor driver fixes and cleanups

  Hardware features:

   - Support for MTE store-only checking (FEAT_MTE_STORE_ONLY)

   - Support for reporting the non-address bits during a synchronous MTE
     tag check fault (FEAT_MTE_TAGGED_FAR)

   - Optimise the TLBI when folding/unfolding contiguous PTEs on
     hardware with FEAT_BBM (break-before-make) level 2 and no TLB
     conflict aborts

  Software features:

   - Enable HAVE_LIVEPATCH after implementing arch_stack_walk_reliable()
     and using the text-poke API for late module relocations

   - Force VMAP_STACK always on and change arm64_efi_rt_init() to use
     arch_alloc_vmap_stack() in order to avoid KASAN false positives

  ACPI:

   - Improve SPCR handling and messaging on systems lacking an SPCR
     table

  Debug:

   - Simplify the debug exception entry path

   - Drop redundant DBG_MDSCR_* macros

  Kselftests:

   - Cleanups and improvements for SME, SVE and FPSIMD tests

  Miscellaneous:

   - Optimise loop to reduce redundant operations in contpte_ptep_get()

   - Remove ISB when resetting POR_EL0 during signal handling

   - Mark the kernel as tainted on SEA and SError panic

   - Remove redundant gcs_free() call"

bc46b7cbc5 s390 updates for 6.17 merge window 
- Standardize on the __ASSEMBLER__ macro that is provided by GCC
   and Clang compilers and replace __ASSEMBLY__ with  __ASSEMBLER__
   in both uapi and non-uapi headers
 
 - Explicitly include <linux/export.h> in architecture and driver
   files which contain an EXPORT_SYMBOL() and remove the include
   from the files which do not contain the EXPORT_SYMBOL()
 
 - Use the full title of "z/Architecture Principles of Operation"
   manual and the name of a section where facility bits are listed
 
 - Use -D__DISABLE_EXPORTS for files in arch/s390/boot to avoid
   unnecessary slowing down of the build and confusing external
   kABI tools that process symtypes data
 
 - Print additional unrecoverable machine check information to make
   the root cause analysis easier
 
 - Move cmpxchg_user_key() handling to uaccess library code, since
   the generated code is large anyway and there is no benefit if it
   is inlined
 
 - Fix a problem when cmpxchg_user_key() is executing a code with a
   non-default key: if a system is IPL-ed with "LOAD NORMAL", and
   the previous system used storage keys where the fetch-protection
   bit was set for some pages, and the cmpxchg_user_key() is located
   within such page, a protection exception happens
 
 - Either the external call or emergency signal order is used to send
   an IPI to a remote CPU. Use the external order only, since it is at
   least as good and sometimes even better, than the emergency signal
 
 - In case of an early crash the early program check handler prints
   more or less random value of the last breaking event address, since
   it is not initialized properly. Copy the last breaking event address
   from the lowcore to pt_regs to address this
 
 - During STP synchronization check udelay() can not be used, since the
   first CPU modifies tod_clock_base and get_tod_clock_monotonic() might
   return a non-monotonic time. Instead, busy-loop on other CPUs, while
   the the first CPU actually handles the synchronization operation
 
 - When debugging the early kernel boot using QEMU with the -S flag and
   GDB attached, skip the decompressor and start directly in kernel
 
 - Rename PAI Crypto event 4210 according to z16 and z17 "z/Architecture
   Principles of Operation" manual
 
 - Remove the in-kernel time steering support in favour of the new s390
   PTP driver, which allows the kernel clock steered more precisely
 
 - Remove a possible false-positive warning in pte_free_defer(), which
   could be triggered in a valid case KVM guest process is initializing

Core scheduler changes:
 
  - Better tracking of maximum lag of tasks in presence of different
    slices duration, for better handling of lag in the fair
    scheduler. (Vincent Guittot)
 
  - Clean up and standardize #if/#else/#endif markers throughout
    the entire scheduler code base (Ingo Molnar)
 
  - Make SMP unconditional: build the SMP scheduler's
    data structures and logic on UP kernel too, even though
    they are not used, to simplify the scheduler and remove
    around 200 #ifdef/[#else]/#endif blocks from the
    scheduler. (Ingo Molnar)
 
  - Reorganize cgroup bandwidth control interface handling
    for better interfacing with sched_ext (Tejun Heo)
 
 Balancing:

  - Simplify and clean up build_sched_topology() (Li Chen)
  - Optimize build_sched_topology() on large machines (Li Chen)
 
 Real-time scheduling:
 
  - Add initial version of proxy execution: a mechanism for mutex-owning
    tasks to inherit the scheduling context of higher priority waiters.
    Currently limited to a single runqueue and conditional on CONFIG_EXPERT,
    and other limitations. (John Stultz, Peter Zijlstra, Valentin Schneider)

    (Peter Zijlstra)
 
 Rust changes:

    function calls (Kunwu Chan, Panagiotis Foliadis)
 
  - Add might_sleep() support for Rust code: Rust's "#[track_caller]"

    defined as a macro (Fujita Tomonori)
 
  - Introduce file_from_location() (Boqun Feng)
 
 Debugging & instrumentation:
 
  - Make clangd usable with scheduler source code files again (Peter Zijlstra)
 
  - tools: Add root_domains_dump.py which dumps root domains info (Juri Lelli)
 
  - tools: Add dl_bw_dump.py for printing bandwidth accounting info (Juri Lelli)
 
 Misc cleanups & fixes:
 
  - Remove play_idle() (Feng Lee)

f627b51aaa compiler_types: Provide __no_kstack_erase to disable coverage only on Clang 
In order to support Clang's stack depth tracking (for Linux's kstack_erase
feature), the coverage sanitizer needed to be disabled for __init (and
__head) section code. Doing this universally (i.e. for GCC too) created
a number of unexpected problems, ranging from changes to inlining logic
to failures to DCE code on earlier GCC versions.

Since this change is only needed for Clang, specialize it so that GCC
doesn't see the change as it isn't needed there (the GCC implementation
of kstack_erase uses a GCC plugin that removes stack depth tracking
instrumentation from __init sections during a late pass in the IR).

Successfully build and boot tested with GCC 12 and Clang 22.

Fixes: 381a38ea53 ("init.h: Disable sanitizer coverage for __init and __head")

 - Map the SNP calling area pages too so that OVMF EFI fw can issue SVSM
   calls properly with the goal of implementing EFI variable store in
   the SVSM - a component which is trusted by the guest, vs in the
   firmware, which is not

 - Allow the kernel to handle #VC exceptions from EFI runtime services
   properly when running as a SNP guest

 - Rework and cleanup the SNP guest request issue glue code a bit

fc525d625a kstack_erase: Fix missed export of renamed KSTACK_ERASE_CFLAGS 
Certain targets disable kstack_erase by filtering out KSTACK_ERASE_CFLAGS
rather than adding DISABLE_KSTACK_ERASE. The renaming to kstack_erase
missed the CFLAGS export, which broke those build targets (e.g. x86
vdso32).

Fixes: 76261fc7d1 ("stackleak: Split KSTACK_ERASE_CFLAGS from GCC_PLUGINS_CFLAGS")
