      Pull modules updates from Luis Chamberlain:
       "Nothing exciting at all for modules for v6.3.
      
        The biggest change is just the change of INSTALL_MOD_DIR from "extra"
        to "updates" which I found lingered for ages for no good reason while
        testing the CXL mock driver [0].
      
        The CXL mock driver has no kconfig integration and requires building
        an external module... and re-building the *rest* of the production
        drivers. This mock driver when loaded but not the production ones will
        crash.
      
        All this can obviously be fixed by integrating kconfig semantics into
        such test module, however that's not desirable by the maintainer, and
        so sensible defaults must be used to ensure a default "make
        modules_install" will suffice for most distros which do not have a
        file like /etc/depmod.d/dist.conf with something like `search updates
        extra built-in`.
      
        Since most distros rely on kmod and since its inception the "updates"
        directory is always in the search path it makes more sense to use that
        than the "extra" which only *some* RH based systems rely on.
      
        All this stuff has been on linux-next for a while"

       "Miscellaneous:
      
         - Add Ian Rogers to MAINTAINERS as a perf tools reviewer.
      
         - Add support for retire latency feature (pipeline stall of a
           instruction compared to the previous one, in cycles) present on
           some Intel processors.
      
         - Add 'perf c2c' report option to show false sharing with adjacent
           cachelines, to be used in machines with cacheline prefetching,
           where accesses to a cacheline brings the next one too.
      
         - Skip 'perf test bpf' when the required kernel-debuginfo package
           isn't installed.
      
         - Avoid d3-flame-graph package dependency in 'perf script flamegraph',
           making this feature more generally available.
      
         - Add JSON metric events to present CPI stall cycles in Power10.

           Please note that to have the -b option (BPF) working above one has

         - Add more 'perf test' entries to test these new features.
      
        perf script:
      
         - Add 'cgroup' field for 'perf script' output:
      
              $ perf record --all-cgroups -- true
              $ perf script -F comm,pid,cgroup
                        true 337112  /user.slice/user-657345.slice/user@657345.service/...

                        true 337112  /user.slice/user-657345.slice/user@657345.service/...
      
         - Add support for showing branch speculation information in 'perf
           script' and in the 'perf report' raw dump (-D).
      
        perf record:
      
         - Fix 'perf record' segfault with --overwrite and --max-size.
      
        perf test/bench:
      
         - Switch basic BPF filtering test to use syscall tracepoint to avoid
           the variable number of probes inserted when using the previous
           probe point (do_epoll_wait) that happens on different CPU
           architectures.
      
         - Fix DWARF unwind test by adding non-inline to expected function in
           a backtrace.
      
         - Use 'grep -c' where the longer form 'grep | wc -l' was being used.
      
         - Add getpid and execve benchmarks to 'perf bench syscall'.
      
        Intel PT:
      
         - Add support for synthesizing "cycle" events from Intel PT traces as
           we support "instruction" events when Intel PT CYC packets are
           available. This enables much more accurate profiles than when using
           the regular 'perf record -e cycles' (the default) when the workload
           lasts for very short periods (<10ms).
      
         - .plt symbol handling improvements, better handling IBT (in the past
           MPX) done in the context of decoding Intel PT processor traces,
           IFUNC symbols on x86_64, static executables, understanding .plt.got
           symbols on x86_64.
      
         - Add a 'perf test' to test symbol resolution, part of the .plt
           improvements series, this tests things like symbol size in contexts
           where only the symbol start is available (kallsyms), etc.
      
         - Better handle auxtrace/Intel PT data when using pipe mode (perf
           record sleep 1|perf report).
      
         - Fix symbol lookup with kcore with multiple segments match stext,
           getting the symbol resolution to just show DSOs as unknown.
      
        ARM:
      
         - Timestamp improvements for ARM64 systems with ETMv4 (Embedded Trace
           Macrocell v4).
      
         - Ensure ARM64 CoreSight timestamps don't go backwards.
      
         - Document that ARM64 SPE (Statistical Profiling Extension) is used
           with 'perf c2c/mem'.
      
         - Add raw decoding for ARM64 SPEv1.2 previous branch address.
      
         - Update neoverse-n2-v2 ARM vendor events (JSON tables): topdown L1,
           TLB, cache, branch, PE utilization and instruction mix metrics.
      
         - Update decoder code for OpenCSD version 1.4, on ARM64 systems.
      
         - Fix command line auto-complete of CPU events on aarch64.
      
        Build:
      
         - Fix 'perf probe' and 'perf test' when libtraceevent isn't linked,
           as several tests use tracepoints, those should be skipped.
      
         - More fallout fixes for the removal of tools/lib/traceevent/.
      
         - Fix build error when linking with libpfm"

        writing to the ring buffer, there was an integrity check of the ring
        buffer in the iterator read code, that expected the ring buffer to be
        write disabled. This caused the integrity check to trigger when stress
        reading the "trace" file while writing was happening.
      
        The integrity check is a bit aggressive (and has never triggered in
        practice). Change it so that it checks just the integrity of the
        linked pages without clearing the flags inside the pointers. This
        removes the warning that was being triggered"
      
      [ Heh. This was supposed to have gone in last week before the 6.2
        release, but Steven forgot to actually add me to the participants of
        the pull request, so here it is, a week later   - Linus ]

       "The largest subset of this is from David Howells et al: making the
        cifs/smb3 driver pass iov_iters down to the lowest layers, directly to
        the network transport rather than passing lists of pages around,
        helping multiple areas:
      
         - Pin user pages, thereby fixing the race between concurrent DIO read
           and fork, where the pages containing the DIO read buffer may end up
           belonging to the child process and not the parent - with the result
           that the parent might not see the retrieved data.
      
         - cifs shouldn't take refs on pages extracted from non-user-backed
           iterators (eg. KVEC). With these changes, cifs will apply the
           appropriate cleanup.
      
         - Making it easier to transition to using folios in cifs rather than
           pages by dealing with them through BVEC and XARRAY iterators.
      
         - Allowing cifs to use the new splice function
      
        The remainder are:
      
         - fixes for stable, including various fixes for uninitialized memory,
           wrong length field causing mount issue to very old servers,
           important directory lease fixes and reconnect fixes
      
         - cleanups (unused code removal, change one element array usage, and
           a change form strtobool to kstrtobool, and Kconfig cleanups)
      
         - SMBDIRECT (RDMA) fixes including iov_iter integration and UAF fixes
      
         - reconnect fixes
      
         - multichannel fixes, including improving channel allocation (to
           least used channel)
      
         - remove the last use of lock_page_killable by moving to

      Pull nfsd updates from Chuck Lever:
       "Two significant security enhancements are part of this release:
      
         - NFSD's RPC header encoding and decoding, including RPCSEC GSS and
           gssproxy header parsing, has been overhauled to make it more
           memory-safe.
      
         - Support for Kerberos AES-SHA2-based encryption types has been added
           for both the NFS client and server. This provides a clean path for
           deprecating and removing insecure encryption types based on DES and
           SHA-1. AES-SHA2 is also FIPS-140 compliant, so that NFS with
           Kerberos may now be used on systems with fips enabled.
      
        In addition to these, NFSD is now able to handle crossing into an
        auto-mounted mount point on an exported NFS mount. A number of fixes
        have been made to NFSD's server-side copy implementation.
      
        RPC metrics have been converted to per-CPU variables. This helps
        reduce unnecessary cross-CPU and cross-node memory bus traffic, and
        significantly reduces noise when KCSAN is enabled"

      Pull ATA updates from Damien Le Moal:
      
       - Small cleanup of the pata_octeon driver to drop a useless platform
         callback (Uwe)
      
       - Simplify ata_scsi_cmd_error_handler() code using the fact that
         ap->ops->error_handler is NULL most of the time (Wenchao)
      
       - Several patches improving libata error handling. This is in
         preparation for supporting the command duration limits (CDL) feature.
         The changes allow handling corner cases of ATA NCQ errors which do
         not happen with regular drives but will be triggered with CDL drives
         (Niklas)
      
       - Simplify the qc_fill_rtf operation (me)
      
       - Improve SCSI command translation for REPORT_SUPPORTED_OPERATION_CODES
         command (me)
      
       - Cleanup of libata FUA handling.
      
         This falls short of enabling FUA for ATA drives that support it by
         default as there were concerns that old drives would break. The
         series however fixes several issues with the FUA support to ensure
         that FUA is reported as being supported only for drives that can
         handle all possible write cases (NCQ and non-NCQ). A check in the
         block layer is also added to ensure that we never see read FUA
         commands (current behavior) (me)
      
       - Several patches to move the old PARIDE (parallel port IDE) driver to
         libata as pata_parport. Given that this driver also needs protocol
         modules, the driver code resides in its own pata_parport directoy
         under drivers/ata (Ondrej)

      Merge tag 'for-6.3/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
      
      Pull device mapper updates from Mike Snitzer:
      
       - Fix DM cache target to free background tracker work items, otherwise
         slab BUG will occur when kmem_cache_destroy() is called.
      
       - Improve 2 of DM's shrinker names to reflect their use.
      
       - Fix the DM flakey target to not corrupt the zero page. Fix dm-flakey
         on 32-bit hughmem systems by using bvec_kmap_local instead of
         page_address. Also, fix logic used when imposing the
         "corrupt_bio_byte" feature.
      
       - Stop using WQ_UNBOUND for DM verity target's verify_wq because it
         causes significant Android latencies on ARM64 (and doesn't show real
         benefit on other architectures).
      
       - Add negative check to catch simple case of a DM table referencing
         itself. More complex scenarios that use intermediate devices to
         self-reference still need to be avoided/handled in userspace.
      
       - Fix DM core's resize to only send one uevent instead of two. This
         fixes a race with udev, that if udev wins, will cause udev to miss
         uevents (which caused premature unmount attempts by systemd).
      
       - Add cond_resched() to workqueue functions in DM core, dn-thin and
         dm-cache so that their loops aren't the cause of unintended cpu
         scheduling fairness issues.
      
       - Fix all of DM's checkpatch errors and warnings (famous last words).
         Various other small cleanups.
