cbbf0a759f * MTD changes: 
Apart from a binding conversion to yaml, only minor changes/small fixes
 have been merged.
 
 * Raw NAND changes:
 
 Various controller drivers received minor fixes like DMA mapping checks,
 better timing derivations or bitflip statistics.
 It has also been discovered that some Hynix NAND flashes were not
 supporting read-retries, which is not properly supported.
 
 * SPI NAND changes:
 
 In order to support high-speed modes, certain chips need extra
 configuration like adding more dummy cycles. This is now possible,
 especially on Winbond chips.
 
 Aside from that, Gigadevice gets support for a new chip (GD5F1GM9).
 
 * SPI NOR changes:
 
 A notable changes is the fix for exiting 4-byte addressing on Infineon
 SEMPER flashes. These flashes do not support the standard EX4B
 opcode (E9h), and use a vendor-specific opcode (B8h) instead.
 
 There is also a fix for unlocking flashes that are write-protected at
 power-on. This was caused by using an uninitialized mtd_info in
 spi_nor_try_unlock_all().

2d945dde7f This is the usual collection of primarily clk driver updates. The big part of 
the diff is all the new Qualcomm clk drivers added for a few SoCs they're
 working on. The other two vendors with significant work this cycle are Renesas
 and Amlogic. Renesas adds a bunch of clks to existing drivers and supports some
 new SoCs while Amlogic is starting a significant refactoring to simplify their
 code.
 
 The core framework gained a pair of helpers to get the 'struct device' or
 'struct device_node' associated with a 'struct clk_hw'. Some associated KUnit
 tests were added for these simple helpers as well. Beyond that core change
 there are lots of little fixes throughout the clk drivers for the stuff we see
 every day, wrong clk driver data that affects tree topology or supported
 frequencies, etc. They're not found until the clks are actually used by some
 consumer device driver.
 
 New Drivers:
  - Global, display, gpu, video, camera, tcsr, and rpmh clock controller for the
    Qualcomm Milos SoC
  - Camera, display, GPU, and video clock controllers for Qualcomm QCS615
  - Video clock controller driver for Qualcomm SM6350
  - Camera clock controller driver for Qualcomm SC8180X
  - I3C clocks and resets on Renesas RZ/G3E
  - Expanded Serial Peripheral Interface (xSPI) clocks and resets on
    Renesas RZ/V2H(P) and RZ/V2N
  - SPI (RSPI) clocks and resets on Renesas RZ/V2H(P)
  - SDHI and I2C clocks on Renesas RZ/T2H and RZ/N2H
  - Ethernet clocks and resets on Renesas RZ/G3E
  - Initial support for the Renesas RZ/T2H (R9A09G077) and RZ/N2H
    (R9A09G087) SoCs
  - Ethernet clocks and resets on Renesas RZ/V2H and RZ/V2N
  - Timer, I2C, watchdog, GPU, and USB2.0 clocks and resets on Renesas
    RZ/V2N
 
 Updates:
  - Support atomic PWMs in the PWM clk driver
  - clk_hw_get_dev() and clk_hw_get_of_node() helpers
  - Replace round_rate() with determine_rate() in various clk drivers
  - Convert clk DT bindings to DT schema format for DT validation
  - Various clk driver cleanups and refactorings from static analysis tools and
    possibly real humans
  - A lot of little fixes here and there to things like clk tree topology,
    missing frequencies, flagging clks as critical, etc. The full details are in
    the commits and sub-tree merge logs

c93529ad4f iommufd 6.17 merge window pull 
- IOMMU HW now has features to directly assign HW command queues to a
   guest VM. In this mode the command queue operates on a limited set of
   invalidation commands that are suitable for improving guest invalidation
   performance and easy for the HW to virtualize.
 
   This PR brings the generic infrastructure to allow IOMMU drivers to
   expose such command queues through the iommufd uAPI, mmap the doorbell
   pages, and get the guest physical range for the command queue ring
   itself.
 
 - An implementation for the NVIDIA SMMUv3 extension "cmdqv" is built on
   the new iommufd command queue features. It works with the existing SMMU
   driver support for cmdqv in guest VMs.
 
 - Many precursor cleanups and improvements to support the above cleanly,
   changes to the general ioctl and object helpers, driver support for
   VDEVICE, and mmap pgoff cookie infrastructure.
 
 - Sequence VDEVICE destruction to always happen before VFIO device
   destruction. When using the above type features, and also in future
   confidential compute, the internal virtual device representation becomes
   linked to HW or CC TSM configuration and objects. If a VFIO device is
   removed from iommufd those HW objects should also be cleaned up to
   prevent a sort of UAF. This became important now that we have HW backing
   the VDEVICE.
 
 - Fix one syzkaller found error related to math overflows during iova
   allocation

Merge tag 'for-linus-iommufd' of git://git.kernel.org/pub/scm/linux/kernel/git/jgg/iommufd

Pull iommufd updates from Jason Gunthorpe:
 "This broadly brings the assigned HW command queue support to iommufd.
  This feature is used to improve SVA performance in VMs by avoiding
  paravirtualization traps during SVA invalidations.

  Along the way I think some of the core logic is in a much better state
  to support future driver backed features.

  Summary:

   - IOMMU HW now has features to directly assign HW command queues to a
     guest VM. In this mode the command queue operates on a limited set
     of invalidation commands that are suitable for improving guest
     invalidation performance and easy for the HW to virtualize.

     This brings the generic infrastructure to allow IOMMU drivers to
     expose such command queues through the iommufd uAPI, mmap the
     doorbell pages, and get the guest physical range for the command
     queue ring itself.

   - An implementation for the NVIDIA SMMUv3 extension "cmdqv" is built
     on the new iommufd command queue features. It works with the
     existing SMMU driver support for cmdqv in guest VMs.

   - Many precursor cleanups and improvements to support the above
     cleanly, changes to the general ioctl and object helpers, driver
     support for VDEVICE, and mmap pgoff cookie infrastructure.

   - Sequence VDEVICE destruction to always happen before VFIO device
     destruction. When using the above type features, and also in future
     confidential compute, the internal virtual device representation
     becomes linked to HW or CC TSM configuration and objects. If a VFIO
     device is removed from iommufd those HW objects should also be
     cleaned up to prevent a sort of UAF. This became important now that
     we have HW backing the VDEVICE.

   - Fix one syzkaller found error related to math overflows during iova
     allocation"

831462ff3e LEDs for for v6.17 
- Improvements & Fixes
   * A fix has been implemented in QCOM Flash to prevent incorrect register
     access when the driver is re-bound. This is solved by duplicating a static
     register array during the probe function, which prevents register addresses
     from being miscalculated after multiple binds.
   * The LP50xx driver now correctly handles the 'reg' property in device tree
     child nodes to ensure the multi_index is set correctly. This prevents
     issues where LEDs could be controlled incorrectly if the device tree nodes
     were processed in a different order. An error is returned if the reg
     property is missing or out of range.
   * A Kconfig dependency on between TPS6131x and V4L2_FLASH_LED_CLASS has been
     added to prevent a build failure when the driver is built-in and the V4L2
     flash infrastructure is a loadable module.
   * A potential buffer overflow warning in PCA955x was reported by older GCC
     versions has been fixed by using a more precise format specifier when
     creating the default LED label.
 
 - Cleanups & Refactoring
   * The MAINTAINERS file entry for the TPS6131X flash LED driver has been
     corrected to point to the correct device tree binding file name.
   * A comment in the Flash Class for the flash_timeout setter has been
     corrected to "flash timeout" from "flash duration" for accuracy.
   * The of_led_get() function is no longer exported as it has no users
     outside of its own module.
 
 - Removals
   * The commit to configure LED blink intervals for hardware offload in the
     Netdev Trigger has been reverted. This change was found to break existing
     PHY drivers by putting their LEDs into a permanent, unconditional blinking
     state.
 
 - Device Tree Bindings Updates
   * The binding for LP50xx has been updated to document that the child reg
     property is the index within the LED bank. The example was also updated to
     use correct values.
   * The JNCP5623 binding has been updated to add 0x39 as a valid I2C address,
     as it is used by the NCP5623C variant.

12ed593ee8 Capabilities update for 6.17 
This branch contains two patches:
 
   cdd73b1666 uapi: fix broken link in linux/capability.h
 
 This updates documentation in capability.h.
 
   337490f000 exec: Correct the permission check for unsafe exec
 
 This is not a trivial patch, but fixes a real problem where during
 exec, different effective and real credentials were assumed to mean
 changed credentials, making it impossible in the no-new-privs case
 to keep different uid and euid.
 
 These are available at:
 
    git://git.kernel.org/pub/scm/linux/kernel/git/sergeh/linux.git #caps-pr-20250729

  The most interesting is probably Amir's change modifying the meaning

  you care about those). There's no change for the common cases of no
  fsnotify watches or no permission event watches. But when there are

  FAN_ACCESS_PERM watch (which nobody uses in practice) we are now able
  optimize away unnecessary cache loads from the read path"

Linus Torvalds
63eb28bb14 ARM: 
- Host driver for GICv5, the next generation interrupt controller for
   arm64, including support for interrupt routing, MSIs, interrupt
   translation and wired interrupts.
 
 - Use FEAT_GCIE_LEGACY on GICv5 systems to virtualize GICv3 VMs on
   GICv5 hardware, leveraging the legacy VGIC interface.
 
 - Userspace control of the 'nASSGIcap' GICv3 feature, allowing
   userspace to disable support for SGIs w/o an active state on hardware
   that previously advertised it unconditionally.
 
 - Map supporting endpoints with cacheable memory attributes on systems
   with FEAT_S2FWB and DIC where KVM no longer needs to perform cache
   maintenance on the address range.
 
 - Nested support for FEAT_RAS and FEAT_DoubleFault2, allowing the guest
   hypervisor to inject external aborts into an L2 VM and take traps of
   masked external aborts to the hypervisor.
 
 - Convert more system register sanitization to the config-driven
   implementation.
 
 - Fixes to the visibility of EL2 registers, namely making VGICv3 system
   registers accessible through the VGIC device instead of the ONE_REG
   vCPU ioctls.
 
 - Various cleanups and minor fixes.
 
 LoongArch:
 
 - Add stat information for in-kernel irqchip
 
 - Add tracepoints for CPUCFG and CSR emulation exits
 
 - Enhance in-kernel irqchip emulation
 
 - Various cleanups.
 
 RISC-V:
 
 - Enable ring-based dirty memory tracking
 
 - Improve perf kvm stat to report interrupt events
 
 - Delegate illegal instruction trap to VS-mode
 
 - MMU improvements related to upcoming nested virtualization
 
 s390x
 
 - Fixes
 
 x86:
 
 - Add CONFIG_KVM_IOAPIC for x86 to allow disabling support for I/O APIC,
   PIC, and PIT emulation at compile time.
 
 - Share device posted IRQ code between SVM and VMX and
   harden it against bugs and runtime errors.
 
 - Use vcpu_idx, not vcpu_id, for GA log tag/metadata, to make lookups O(1)
   instead of O(n).
 
 - For MMIO stale data mitigation, track whether or not a vCPU has access to
   (host) MMIO based on whether the page tables have MMIO pfns mapped; using
   VFIO is prone to false negatives
 
 - Rework the MSR interception code so that the SVM and VMX APIs are more or
   less identical.
 
 - Recalculate all MSR intercepts from scratch on MSR filter changes,
   instead of maintaining shadow bitmaps.
 
 - Advertise support for LKGS (Load Kernel GS base), a new instruction
   that's loosely related to FRED, but is supported and enumerated
   independently.
 
 - Fix a user-triggerable WARN that syzkaller found by setting the vCPU
   in INIT_RECEIVED state (aka wait-for-SIPI), and then putting the vCPU
   into VMX Root Mode (post-VMXON).  Trying to detect every possible path
   leading to architecturally forbidden states is hard and even risks
   breaking userspace (if it goes from valid to valid state but passes
   through invalid states), so just wait until KVM_RUN to detect that
   the vCPU state isn't allowed.
 
 - Add KVM_X86_DISABLE_EXITS_APERFMPERF to allow disabling interception of
   APERF/MPERF reads, so that a "properly" configured VM can access
   APERF/MPERF.  This has many caveats (APERF/MPERF cannot be zeroed
   on vCPU creation or saved/restored on suspend and resume, or preserved
   over thread migration let alone VM migration) but can be useful whenever
   you're interested in letting Linux guests see the effective physical CPU
   frequency in /proc/cpuinfo.
 
 - Reject KVM_SET_TSC_KHZ for vm file descriptors if vCPUs have been
   created, as there's no known use case for changing the default
   frequency for other VM types and it goes counter to the very reason
   why the ioctl was added to the vm file descriptor.  And also, there
   would be no way to make it work for confidential VMs with a "secure"
   TSC, so kill two birds with one stone.
 
 - Dynamically allocation the shadow MMU's hashed page list, and defer
   allocating the hashed list until it's actually needed (the TDP MMU
   doesn't use the list).
 
 - Extract many of KVM's helpers for accessing architectural local APIC
   state to common x86 so that they can be shared by guest-side code for
   Secure AVIC.
 
 - Various cleanups and fixes.
 
 x86 (Intel):
 
 - Preserve the host's DEBUGCTL.FREEZE_IN_SMM when running the guest.
   Failure to honor FREEZE_IN_SMM can leak host state into guests.
 
 - Explicitly check vmcs12.GUEST_DEBUGCTL on nested VM-Enter to prevent
   L1 from running L2 with features that KVM doesn't support, e.g. BTF.
 
 x86 (AMD):
 
 - WARN and reject loading kvm-amd.ko instead of panicking the kernel if the
   nested SVM MSRPM offsets tracker can't handle an MSR (which is pretty
   much a static condition and therefore should never happen, but still).
 
 - Fix a variety of flaws and bugs in the AVIC device posted IRQ code.
 
 - Inhibit AVIC if a vCPU's ID is too big (relative to what hardware
   supports) instead of rejecting vCPU creation.
 
 - Extend enable_ipiv module param support to SVM, by simply leaving

   numbers of VMs.  Such use cases typically don't actually use irqbypass,

 - Track irqbypass's "token" as "struct eventfd_ctx *" instead of a "void *",
   to avoid making a simple concept unnecessarily difficult to understand.
 
 - Decouple device posted IRQs from VFIO device assignment, as binding a VM
   to a VFIO group is not a requirement for enabling device posted IRQs.
 
 - Clean up and document/comment the irqfd assignment code.
 
 - Disallow binding multiple irqfds to an eventfd with a priority waiter,
   i.e.  ensure an eventfd is bound to at most one irqfd through the entire
   host, and add a selftest to verify eventfd:irqfd bindings are globally
   unique.
 
 - Add a tracepoint for KVM_SET_MEMORY_ATTRIBUTES to help debug issues
   related to private <=> shared memory conversions.
 
 - Drop guest_memfd's .getattr() implementation as the VFS layer will call
   generic_fillattr() if inode_operations.getattr is NULL.
 
 - Fix issues with dirty ring harvesting where KVM doesn't bound the
   processing of entries in any way, which allows userspace to keep KVM
   in a tight loop indefinitely.
 
 - Kill off kvm_arch_{start,end}_assignment() and x86's associated tracking,
   now that KVM no longer uses assigned_device_count as a heuristic for
   either irqbypass usage or MDS mitigation.
 
 Selftests:
 
 - Fix a comment typo.

Pull kvm updates from Paolo Bonzini:
 "ARM:

   - Host driver for GICv5, the next generation interrupt controller for
     arm64, including support for interrupt routing, MSIs, interrupt
     translation and wired interrupts

   - Use FEAT_GCIE_LEGACY on GICv5 systems to virtualize GICv3 VMs on
     GICv5 hardware, leveraging the legacy VGIC interface

   - Userspace control of the 'nASSGIcap' GICv3 feature, allowing
     userspace to disable support for SGIs w/o an active state on
     hardware that previously advertised it unconditionally

   - Map supporting endpoints with cacheable memory attributes on
     systems with FEAT_S2FWB and DIC where KVM no longer needs to
     perform cache maintenance on the address range

   - Nested support for FEAT_RAS and FEAT_DoubleFault2, allowing the
     guest hypervisor to inject external aborts into an L2 VM and take
     traps of masked external aborts to the hypervisor

   - Convert more system register sanitization to the config-driven
     implementation

   - Fixes to the visibility of EL2 registers, namely making VGICv3
     system registers accessible through the VGIC device instead of the
     ONE_REG vCPU ioctls

   - Various cleanups and minor fixes

  LoongArch:

   - Add stat information for in-kernel irqchip

   - Add tracepoints for CPUCFG and CSR emulation exits

   - Enhance in-kernel irqchip emulation

   - Various cleanups

  RISC-V:

   - Enable ring-based dirty memory tracking

   - Improve perf kvm stat to report interrupt events

   - Delegate illegal instruction trap to VS-mode

   - MMU improvements related to upcoming nested virtualization

  s390x

   - Fixes

  x86:

   - Add CONFIG_KVM_IOAPIC for x86 to allow disabling support for I/O
     APIC, PIC, and PIT emulation at compile time

   - Share device posted IRQ code between SVM and VMX and harden it
     against bugs and runtime errors

   - Use vcpu_idx, not vcpu_id, for GA log tag/metadata, to make lookups
     O(1) instead of O(n)

   - For MMIO stale data mitigation, track whether or not a vCPU has
     access to (host) MMIO based on whether the page tables have MMIO
     pfns mapped; using VFIO is prone to false negatives

   - Rework the MSR interception code so that the SVM and VMX APIs are
     more or less identical

   - Recalculate all MSR intercepts from scratch on MSR filter changes,
     instead of maintaining shadow bitmaps

   - Advertise support for LKGS (Load Kernel GS base), a new instruction
     that's loosely related to FRED, but is supported and enumerated
     independently

   - Fix a user-triggerable WARN that syzkaller found by setting the
     vCPU in INIT_RECEIVED state (aka wait-for-SIPI), and then putting
     the vCPU into VMX Root Mode (post-VMXON). Trying to detect every
     possible path leading to architecturally forbidden states is hard
     and even risks breaking userspace (if it goes from valid to valid
     state but passes through invalid states), so just wait until
     KVM_RUN to detect that the vCPU state isn't allowed

   - Add KVM_X86_DISABLE_EXITS_APERFMPERF to allow disabling
     interception of APERF/MPERF reads, so that a "properly" configured
     VM can access APERF/MPERF. This has many caveats (APERF/MPERF
     cannot be zeroed on vCPU creation or saved/restored on suspend and
     resume, or preserved over thread migration let alone VM migration)
     but can be useful whenever you're interested in letting Linux
     guests see the effective physical CPU frequency in /proc/cpuinfo

   - Reject KVM_SET_TSC_KHZ for vm file descriptors if vCPUs have been
     created, as there's no known use case for changing the default
     frequency for other VM types and it goes counter to the very reason
     why the ioctl was added to the vm file descriptor. And also, there
     would be no way to make it work for confidential VMs with a
     "secure" TSC, so kill two birds with one stone

   - Dynamically allocation the shadow MMU's hashed page list, and defer
     allocating the hashed list until it's actually needed (the TDP MMU
     doesn't use the list)

   - Extract many of KVM's helpers for accessing architectural local
     APIC state to common x86 so that they can be shared by guest-side
     code for Secure AVIC

   - Various cleanups and fixes

  x86 (Intel):

   - Preserve the host's DEBUGCTL.FREEZE_IN_SMM when running the guest.
     Failure to honor FREEZE_IN_SMM can leak host state into guests

   - Explicitly check vmcs12.GUEST_DEBUGCTL on nested VM-Enter to
     prevent L1 from running L2 with features that KVM doesn't support,
     e.g. BTF

  x86 (AMD):

   - WARN and reject loading kvm-amd.ko instead of panicking the kernel
     if the nested SVM MSRPM offsets tracker can't handle an MSR (which
     is pretty much a static condition and therefore should never
     happen, but still)

   - Fix a variety of flaws and bugs in the AVIC device posted IRQ code

   - Inhibit AVIC if a vCPU's ID is too big (relative to what hardware
     supports) instead of rejecting vCPU creation

   - Extend enable_ipiv module param support to SVM, by simply leaving
     IsRunning clear in the vCPU's physical ID table entry

   - Disable IPI virtualization, via enable_ipiv, if the CPU is affected
     by erratum #1235, to allow (safely) enabling AVIC on such CPUs

   - Request GA Log interrupts if and only if the target vCPU is
     blocking, i.e. only if KVM needs a notification in order to wake
     the vCPU

   - Intercept SPEC_CTRL on AMD if the MSR shouldn't exist according to

     to SMT and single-socket restrictions. An incompatible policy
     doesn't put the kernel at risk in any way, so there's no reason for

d50b07d05c ring-buffer changes for v6.17: 
- Rewind persistent ring buffer on boot
 
   When the persistent ring buffer is being used for live kernel tracing and
   the system crashes, the tool that is reading the trace may not have recorded
   the data when the system crashed. Although the persistent ring buffer still
   has that data, when reading it after a reboot, it will start where it left
   off. That is, what was read will not be accessible.
 
   Instead, on reboot, have the persistent ring buffer restart where the data
   starts and this will allow the tooling to recover what was lost when the
   crash occurred.
 
 - Remove the ring_buffer_read_prepare_sync() logic
 
   Reading the trace file required stopping writing to the ring buffer as the
   trace file is only an iterator and does not consume what it read. It was
   originally not safe to read the ring buffer in this mode and required
   disabling writing. The ring_buffer_read_prepare_sync() logic was used to
   stop each per_cpu ring buffer, call synchronize_rcu() and then start the
   iterator. This was used instead of calling synchronize_rcu() for each
   per_cpu buffer.
 
   Today, the iterator has been updated where it is safe to read the trace file
   while writing to the ring buffer is still occurring. There is no more need
   to do this synchronization and it is causing large delays on machines with
   many CPUs. Remove this unneeded synchronization.
 
 - Make static string array a constant in show_irq_str()
 
   Making the string array into a constant has shown to decrease code text/data
   size.

Merge tag 'trace-ringbuffer-v6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace

Pull ring-buffer updates from Steven Rostedt:

 - Rewind persistent ring buffer on boot

   When the persistent ring buffer is being used for live kernel tracing
   and the system crashes, the tool that is reading the trace may not
   have recorded the data when the system crashed.

   Although the persistent ring buffer still has that data, when reading
   it after a reboot, it will start where it left off. That is, what was
   read will not be accessible.

   Instead, on reboot, have the persistent ring buffer restart where the
   data starts and this will allow the tooling to recover what was lost
   when the crash occurred.

 - Remove the ring_buffer_read_prepare_sync() logic

   Reading the trace file required stopping writing to the ring buffer
   as the trace file is only an iterator and does not consume what it
   read. It was originally not safe to read the ring buffer in this mode
   and required disabling writing. The ring_buffer_read_prepare_sync()
   logic was used to stop each per_cpu ring buffer, call
   synchronize_rcu() and then start the iterator. This was used instead
   of calling synchronize_rcu() for each per_cpu buffer.

   Today, the iterator has been updated where it is safe to read the
   trace file while writing to the ring buffer is still occurring. There
   is no more need to do this synchronization and it is causing large
   delays on machines with many CPUs. Remove this unneeded
   synchronization.

 - Make static string array a constant in show_irq_str()

   Making the string array into a constant has shown to decrease code
   text/data size.

90a871f74b ftrace changes for v6.17: 
- Keep track of when fgraph_ops are registered or not
 
   Keep accounting of when fgraph_ops are registered as if a fgraph_ops is
   registered twice it can mess up the accounting and it will not work as
   expected later. Trigger a warning if something registers it twice as to
   catch bugs before they are found by things just not working as expected.
 
 - Make DYNAMIC_FTRACE always enabled for architectures that support it
 
   As static ftrace (where all functions are always traced) is very expensive
   and only exists to help architectures support ftrace, do not make it an
   option. As soon as an architecture supports DYNAMIC_FTRACE make it use it.
   This simplifies the code.
 
 - Remove redundant config HAVE_FTRACE_MCOUNT_RECORD
 
   The CONFIG_HAVE_FTRACE_MCOUNT was added to help simplify the
   DYNAMIC_FTRACE work, but now every architecture that implements
   DYNAMIC_FTRACE also has HAVE_FTRACE_MCOUNT set too, making it redundant
   with the HAVE_DYNAMIC_FTRACE.
 
 - Make pid_ptr string size match the comment
 
   In print_graph_proc() the pid_ptr string is of size 11, but the comment says
   /* sign + log10(MAX_INT) + '\0' */ which is actually 12.

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.

w25n0xjw chips have a high-speed capability hidden in a configuration
register. Once enabled, dual/quad SDR reads may be performed at a much
higher frequency.

the SR4 register accordingly.

There is already a manufacturer hook, which is manufacturer specific but
not chip specific. We no longer have access to the actual NAND identity
at this stage so let's add a per-chip configuration hook to align the
chip configuration (if any) with the core's setting.

d81ad9d78e mtd: spinand: Add a frequency field to all READ_FROM_CACHE variants 
These macros had initially no frequency field. When I added the "maximum
operation frequency" field, I did it initially on very common macros and
I decided to add an optional field for that (with VA_ARGS) in order to
prevent massively unreadable changes. I then added new variants in the
spinand.h header, and requested a frequency field for them by
default. Some times later, I also added maximum frequencies to other
existing variants, but I did it incorrectly, without noticing I was
wrong because the field was optional.

This mix is error prone, so let's do what I should have done since the
very beginning: add a frequency field to all READ_FROM_CACHE variants.

There is no functional change.

a11a518965 spi: spi-mem: Take into account the actual maximum frequency 
In order to pick the best variant, the duration of each typical
operation is derived and then compared. These durations are based on the
maximum capabilities of the chips, which are commonly the limiting
factors. However there are other possible limiting pieces, such as the
hardware layout, EMC considerations and in some cases, the SPI controller
itself.

We need to take this into account to further refine our variant choice,
so let's use the actual frequency that will be used for the operation
instead of the theoretical maximum.

   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

    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:
 
  - Bump sd->max_newidle_lb_cost when newidle balance fails (Chris Mason)
  - Remove sched_domain_topology_level::flags to simplify the code (Prateek Nayak)
  - 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)
 
  - Deadline scheduler (Juri Lelli):
 
    - Fix dl_servers initialization order (Juri Lelli)
    - Fix DL scheduler's root domain reinitialization logic (Juri Lelli)
    - Fix accounting bugs after global limits change (Juri Lelli)
    - Fix scalability regression by implementing less agressive dl_server handling
      (Peter Zijlstra)
 
 PSI:
 
  - Improve scalability by optimizing psi_group_change() cpu_clock() usage
    (Peter Zijlstra)
 
 Rust changes:
 
  - Make Task, CondVar and PollCondVar methods inline to avoid unnecessary
    function calls (Kunwu Chan, Panagiotis Foliadis)
 
  - Add might_sleep() support for Rust code: Rust's "#[track_caller]"
    mechanism is used so that Rust's might_sleep() doesn't need to be
    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)
 
  - Fix check_preemption_disabled() (Sebastian Andrzej Siewior)

Pull scheduler updates from Ingo Molnar:
 "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:

   - Bump sd->max_newidle_lb_cost when newidle balance fails (Chris
     Mason)

   - Remove sched_domain_topology_level::flags to simplify the code
     (Prateek Nayak)

   - 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)

   - Deadline scheduler (Juri Lelli):
      - Fix dl_servers initialization order (Juri Lelli)
      - Fix DL scheduler's root domain reinitialization logic (Juri
        Lelli)
      - Fix accounting bugs after global limits change (Juri Lelli)
      - Fix scalability regression by implementing less agressive
        dl_server handling (Peter Zijlstra)

  PSI:

   - Improve scalability by optimizing psi_group_change() cpu_clock()
     usage (Peter Zijlstra)

  Rust changes:

   - Make Task, CondVar and PollCondVar methods inline to avoid
     unnecessary function calls (Kunwu Chan, Panagiotis Foliadis)

   - Add might_sleep() support for Rust code: Rust's "#[track_caller]"
     mechanism is used so that Rust's might_sleep() doesn't need to be
     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)

   - Fix check_preemption_disabled() (Sebastian Andrzej Siewior)

   - Do not call __put_task_struct() on RT if pi_blocked_on is set (Luis
     Claudio R. Goncalves)

   - Correct the comment in place_entity() (wang wei)"

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")
