      Pull compute express link updates from Dan Williams:
       "DOE support is promoted from drivers/cxl/ to drivers/pci/ with Bjorn's
        blessing, and the CXL core continues to mature its media management
        capabilities with support for listing and injecting media errors. Some
        late fixes that missed v6.3-final are also included:
      
         - Refactor the DOE infrastructure (Data Object Exchange
           PCI-config-cycle mailbox) to be a facility of the PCI core rather
           than the CXL core.
      
           This is foundational for upcoming support for PCI
           device-attestation and PCIe / CXL link encryption.
      
         - Add support for retrieving and injecting poison for CXL memory
           expanders.
      
           This enabling uses trace-events to convey CXL media error records
           to user tooling. It includes translation of device-local addresses
           (DPA) to system physical addresses (SPA) and their corresponding
           CXL region.

       "More additions to the Rust core. Importantly, this adds the pin-init
        API, which will be used by other abstractions, such as the
        synchronization ones added here too:
      
         - pin-init API: a solution for the safe pinned initialization
           problem.
      
           This allows to reduce the need for 'unsafe' code in the kernel when
           dealing with data structures that require a stable address. Commit
           90e53c5e ("rust: add pin-init API core") contains a nice
           introduction -- here is an example of how it looks like:
      
              #[pin_data]
              struct Example {
                  #[pin]
                  value: Mutex<u32>,
      
                  #[pin]
                  value_changed: CondVar,
              }
      
              impl Example {
                  fn new() -> impl PinInit<Self> {
                      pin_init!(Self {
                          value <- new_mutex!(0),
                          value_changed <- new_condvar!(),
                      })
                  }
              }
      
              // In a `Box`.
              let b = Box::pin_init(Example::new())?;
      
              // In the stack.
              stack_pin_init!(let s = Example::new());
      
         - 'sync' module:
      
           New types 'LockClassKey' ('struct lock_class_key'), 'Lock',
           'Guard', 'Mutex' ('struct mutex'), 'SpinLock' ('spinlock_t'),
           'LockedBy' and 'CondVar' (uses 'wait_queue_head_t'), plus macros
           such as 'static_lock_class!' and 'new_spinlock!'.
      
           In particular, 'Lock' and 'Guard' are generic implementations that
           contain code that is common to all locks. Then, different backends
           (the new 'Backend' trait) are implemented and used to define types
           like 'Mutex':
      
              type Mutex<T> = Lock<T, MutexBackend>;
      
           In addition, new methods 'assume_init()', 'init_with()' and
           'pin_init_with()' for 'UniqueArc<MaybeUninit<T>>' and 'downcast()'
           for 'Arc<dyn Any + Send + Sync>'; as well as 'Debug' and 'Display'
           implementations for 'Arc' and 'UniqueArc'. Reduced stack usage of
           'UniqueArc::try_new_uninit()', too.
      
         - 'types' module:
      
           New trait 'AlwaysRefCounted' and new type 'ARef' (an owned
           reference to an always-reference-counted object, meant to be used
           in wrappers for C types that have their own ref counting
           functions).
      
           Moreover, new associated functions 'raw_get()' and 'ffi_init()' for
           'Opaque'.
      
         - New 'task' module with a new type 'Task' ('struct task_struct'),
           and a new macro 'current!' to safely get a reference to the current
           one.
      
         - New 'ioctl' module with new '_IOC*' const functions (equivalent to
           the C macros).
      
         - New 'uapi' crate, intended to be accessible by drivers directly.
      
         - 'macros' crate: new 'quote!' macro (similar to the one provided in
           userspace by the 'quote' crate); and the 'module!' macro now allows
           specifying multiple module aliases.
      
         - 'error' module:
      
           New associated functions for the 'Error' type, such as
           'from_errno()' and new functions such as 'to_result()'.
      
         - 'alloc' crate:
      
           More fallible 'Vec' methods: 'try_resize` and
           'try_extend_from_slice' and the infrastructure (imported from the
           Rust standard library) they need"

      Pull clk updates from Stephen Boyd:
       "Nothing looks out of the ordinary in this batch of clk driver updates.
      
        There are a couple patches to the core clk framework, but they're all
        basically cleanups or debugging aids. The driver updates and new
        additions are dominated in the diffstat by Qualcomm and MediaTek
        drivers. Qualcomm gained a handful of new drivers for various SoCs,
        and MediaTek gained a bunch of drivers for MT8188. The MediaTek
        drivers are being modernized as well, so there are updates all over
        that vendor's clk drivers. There's also a couple other new clk drivers
        in here, for example the Starfive JH7110 SoC support is added.
      
        Outside of the two major SoC vendors though, we have the usual
        collection of non-critical fixes and cleanups to various clk drivers.
        It's good to see that we're getting more cleanups and modernization
        patches. Maybe one day we'll be able to properly split clk providers
        from clk consumers.
      
        Core:
         - Print an informational message before disabling unused clks
      
        New Drivers:
         - BCM63268 timer clock and reset controller
         - Frequency Hopping (FHCTL) on MediaTek MT6795, MT8173, MT8192 and
           MT8195 SoCs
         - Mediatek MT8188 SoC clk drivers
         - Clock driver for Sunplus SP7021 SoC
         - Clk driver support for Loongson-2 SoCs

         - GPU clock controller drivers for SM6115, SM6125, SM6375 and SA8775P
           SoCs

       "The big ticket item for this release is that support for RPC-with-TLS
        [RFC 9289] has been added to the Linux NFS server.
      
        The goal is to provide a simple-to-deploy, low-overhead in-transit
        confidentiality and peer authentication mechanism. It can supplement
        NFS Kerberos and it can protect the use of legacy non-cryptographic
        user authentication flavors such as AUTH_SYS. The TLS Record protocol
        is handled entirely by kTLS, meaning it can use either software
        encryption or offload encryption to smart NICs.
      
        Aside from that, work continues on improving NFSD's open file cache.
        Among the many clean-ups in that area is a patch to convert the
        rhashtable to use the list-hashing version of that data structure"

      Pull tracing updates from Steven Rostedt:
      
       - User events are finally ready!
      
         After lots of collaboration between various parties, we finally
         locked down on a stable interface for user events that can also work
         with user space only tracing.
      
         This is implemented by telling the kernel (or user space library, but
         that part is user space only and not part of this patch set), where
         the variable is that the application uses to know if something is
         listening to the trace.
      
         There's also an interface to tell the kernel about these events,
         which will show up in the /sys/kernel/tracing/events/user_events/
         directory, where it can be enabled.
      
         When it's enabled, the kernel will update the variable, to tell the
         application to start writing to the kernel.
      
         See https://lwn.net/Articles/927595/
      
       - Cleaned up the direct trampolines code to simplify arm64 addition of
         direct trampolines.
      
         Direct trampolines use the ftrace interface but instead of jumping to
         the ftrace trampoline, applications (mostly BPF) can register their
         own trampoline for performance reasons.
      
       - Some updates to the fprobe infrastructure. fprobes are more efficient
         than kprobes, as it does not need to save all the registers that
         kprobes on ftrace do. More work needs to be done before the fprobes
         will be exposed as dynamic events.
      
       - More updates to references to the obsolete path of
         /sys/kernel/debug/tracing for the new /sys/kernel/tracing path.
      
       - Add a seq_buf_do_printk() helper to seq_bufs, to print a large buffer
         line by line instead of all at once.
      
         There are users in production kernels that have a large data dump
         that originally used printk() directly, but the data dump was larger
         than what printk() allowed as a single print.
      
         Using seq_buf() to do the printing fixes that.
      
       - Add /sys/kernel/tracing/touched_functions that shows all functions
         that was every traced by ftrace or a direct trampoline. This is used
         for debugging issues where a traced function could have caused a
         crash by a bpf program or live patching.
      
       - Add a "fields" option that is similar to "raw" but outputs the fields
         of the events. It's easier to read by humans.
      
       - Some minor fixes and clean ups.

      Pull scheduler updates from Ingo Molnar:
      
       - Allow unprivileged PSI poll()ing
      
       - Fix performance regression introduced by mm_cid
      
       - Improve livepatch stalls by adding livepatch task switching to
         cond_resched(). This resolves livepatching busy-loop stalls with
         certain CPU-bound kthreads
      
       - Improve sched_move_task() performance on autogroup configs
      
       - On core-scheduling CPUs, avoid selecting throttled tasks to run
      
       - Misc cleanups, fixes and improvements
