       "This introduces support for controlling the Cortex R7 co-processor in
        Renesas Gen3, support for R5F clusters and C71x DSPs on TI J721S2 and
        compute, audio and modem subsystems on Qualcomm SM6350.
      
        It fixes a couple of sparse errors related to memcpy_to/fromio and
        corrects the kerneldoc spelling of "Return:".
      
        The stm32 driver no longer attempts to communicate with the remote
        after the firmware has crashed"

      vfs: fs_context: fix up param length parsing in legacy_parse_param · 722d9484
      Jamie Hill-Daniel authored
      The "PAGE_SIZE - 2 - size" calculation in legacy_parse_param() is an
      unsigned type so a large value of "size" results in a high positive
      value instead of a negative value as expected.  Fix this by getting rid
      of the subtraction.

      Pull more ACPI updates from Rafael Wysocki:
       "The most significant item here is the Platform Firmware Runtime Update
        and Telemetry (PFRUT) support designed to allow certain pieces of the
        platform firmware to be updated on the fly, among other things.
      
        Also important is the e820 handling change on x86 that should work
        around PCI BAR allocation issues on some systems shipping since 2019.
      
        The rest is just a handful of assorted fixes and cleanups on top of
        the ACPI material merged previously.
      
        Specifics:
      
         - Add support for the the Platform Firmware Runtime Update and
           Telemetry (PFRUT) interface based on ACPI to allow certain pieces
           of the platform firmware to be updated without restarting the
           system and to provide a mechanism for collecting platform firmware
           telemetry data (Chen Yu, Dan Carpenter, Yang Yingliang).
      
         - Ignore E820 reservations covering PCI host bridge windows on
           sufficiently recent x86 systems to avoid issues with allocating PCI
           BARs on systems where the E820 reservations cover the entire PCI
           host bridge memory window returned by the _CRS object in the
           system's ACPI tables (Hans de Goede).
      
         - Fix and clean up acpi_scan_init() (Rafael Wysocki).
      
         - Add more sanity checking to ACPI SPCR tables parsing (Mark
           Langsdorf).
      
         - Fix up ACPI APD (AMD Soc) driver initialization (Jiasheng Jiang).
      
         - Drop unnecessary "static" from the ACPI PCC address space handling
           driver added recently (kernel test robot)"
      
      * tag 'acpi-5.17-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:

      Pull perf tool updates from Arnaldo Carvalho de Melo:
       "New features:
      
         - Add 'trace' subcommand for 'perf ftrace', setting the stage for
           more 'perf ftrace' subcommands. Not using a subcommand yields the
           previous behaviour of 'perf ftrace'.
      
         - Add 'latency' subcommand to 'perf ftrace', that can use the
           function graph tracer or a BPF optimized one, via the -b/--use-bpf
           option.

           The original implementation of this command was in the bcc tool.
      
         - Support --cputype option for hybrid events in 'perf stat'.
      
        Improvements:
      
         - Call chain improvements for ARM64.
      
         - No need to do any affinity setup when profiling pids.
      
         - Reduce multiplexing with duration_time in 'perf stat' metrics.
      
         - Improve error message for uncore events, stating that some event
           groups are can only be used in system wide (-a) mode.
      
         - perf stat metric group leader fixes/improvements, including arch
           specific changes to better support Intel topdown events.
      
         - Probe non-deprecated sysfs path first, i.e. try the path
           /sys/devices/system/cpu/cpuN/topology/thread_siblings first, then
           the old /sys/devices/system/cpu/cpuN/topology/core_cpus.
      
         - Disable debuginfod by default in 'perf record', to avoid stalls on
           distros such as Fedora 35.
      
         - Use unbuffered output in 'perf bench' when pipe/tee'ing to a file.
      
         - Enable ignore_missing_thread in 'perf trace'
      
        Fixes:
      
         - Avoid TUI crash when navigating in the annotation of recursive
           functions.
      
         - Fix hex dump character output in 'perf script'.
      
         - Fix JSON indentation to 4 spaces standard in the ARM vendor event
           files.
      
         - Fix use after free in metric__new().
      
         - Fix IS_ERR_OR_NULL() usage in the perf BPF loader.
      
         - Fix up cross-arch register support, i.e. when printing register
           names take into account the architecture where the perf.data file
           was collected.
      
         - Fix SMT fallback with large core counts.
      
         - Don't lower case MetricExpr when parsing JSON files so as not to
           lose info such as the ":G" event modifier in metrics.
      
        perf test:
      
         - Add basic stress test for sigtrap handling to 'perf test'.
      
         - Fix 'perf test' failures on s/390
      
         - Enable system wide for metricgroups test in 'perf test´.
      
         - Use 3 digits for test numbering now we can have more tests.
      
        Arch specific:
      
         - Add events for Arm Neoverse N2 in the ARM JSON vendor event files
      
         - Support PERF_MEM_LVLNUM encodings in powerpc, that came from a
           single patch series, where I incorrectly merged the kernel bits,
           that were then reverted after coordination with Michael Ellerman
           and Stephen Rothwell.
      
         - Add ARM SPE total latency as PERF_SAMPLE_WEIGHT.
      
         - Update AMD documentation, with info on raw event encoding.
      
         - Add support for global and local variants of the "p_stage_cyc" sort
           key, applicable to perf.data files collected on powerpc.
      
         - Remove duplicate and incorrect aux size checks in the ARM CoreSight
           ETM code.
      
        Refactorings:
      
         - Add a perf_cpu abstraction to disambiguate CPUs and CPU map
           indexes, fixing problems along the way.
      
         - Document CPU map methods.
      
        UAPI sync:
      
         - Update arch/x86/lib/mem{cpy,set}_64.S copies used in 'perf bench
           mem memcpy'
      
         - Sync UAPI files with the kernel sources: drm, msr-index,
           cpufeatures.
      
        Build system
      
         - Enable warnings through HOSTCFLAGS.
      
         - Drop requirement for libstdc++.so for libopencsd check
      
        libperf:
      
         - Make libperf adopt perf_counts_values__scale() from tools/perf/util/.
      
         - Add a stat multiplexing test to libperf"

      The interface provided here allows updating certain pieces of the
      platform firmware without restarting the system and collecting
      platform firmware telemetry data.
      
      This also includes a utility for accesing the new interface from user
      space.

      devtmpfs regression fix: reconfigure on each mount · a6097180
      NeilBrown authored
      Prior to Linux v5.4 devtmpfs used mount_single() which treats the given
      mount options as "remount" options, so it updates the configuration of
      the single super_block on each mount.
      
      Since that was changed, the mount options used for devtmpfs are ignored.
      This is a regression which affect systemd - which mounts devtmpfs with
      "-o mode=755,size=4m,nr_inodes=1m".
      
      This patch restores the "remount" effect by calling reconfigure_single()
      
      Fixes: d401727e ("devtmpfs: don't mix {ramfs,shmem}_fill_super() with mount_single()")

      Pull signal/exit/ptrace updates from Eric Biederman:
       "This set of changes deletes some dead code, makes a lot of cleanups
        which hopefully make the code easier to follow, and fixes bugs found
        along the way.
      
        The end-game which I have not yet reached yet is for fatal signals
        that generate coredumps to be short-circuit deliverable from
        complete_signal, for force_siginfo_to_task not to require changing
        userspace configured signal delivery state, and for the ptrace stops
        to always happen in locations where we can guarantee on all
        architectures that the all of the registers are saved and available on
        the stack.
      
        Removal of profile_task_ext, profile_munmap, and profile_handoff_task
        are the big successes for dead code removal this round.
      
        A bunch of small bug fixes are included, as most of the issues
        reported were small enough that they would not affect bisection so I
        simply added the fixes and did not fold the fixes into the changes
        they were fixing.
      
        There was a bug that broke coredumps piped to systemd-coredump. I
        dropped the change that caused that bug and replaced it entirely with
        something much more restrained. Unfortunately that required some
        rebasing.
      
        Some successes after this set of changes: There are few enough calls
        to do_exit to audit in a reasonable amount of time. The lifetime of
        struct kthread now matches the lifetime of struct task, and the
        pointer to struct kthread is no longer stored in set_child_tid. The
        flag SIGNAL_GROUP_COREDUMP is removed. The field group_exit_task is
        removed. Issues where task->exit_code was examined with
        signal->group_exit_code should been examined were fixed.
      
        There are several loosely related changes included because I am
        cleaning up and if I don't include them they will probably get lost.
      
        The original postings of these changes can be found at:
           https://lkml.kernel.org/r/87a6ha4zsd.fsf@email.froward.int.ebiederm.org

      Pull tracing updates from Steven Rostedt:
       "New:
      
         - The Real Time Linux Analysis (RTLA) tool is added to the tools
           directory.
      
         - Can safely filter on user space pointers with: field.ustring ~
           "match-string"
      
         - eprobes can now be filtered like any other event.
      
         - trace_marker(_raw) now uses stream_open() to allow multiple threads
           to safely write to it. Note, this could possibly break existing
           user space, but we will not know until we hear about it, and then
           can revert the change if need be.
      
         - New field in events to display when bottom halfs are disabled.
      
         - Sorting of the ftrace functions are now done at compile time
           instead of at bootup.
      
        Infrastructure changes to support future efforts:
      
         - Added __rel_loc type for trace events. Similar to __data_loc but
           the offset to the dynamic data is based off of the location of the
           descriptor and not the beginning of the event. Needed for user
           defined events.
      
         - Some simplification of event trigger code.
      
         - Make synthetic events process its callback better to not hinder
           other event callbacks that are registered. Needed for user defined
           events.
      
        And other small fixes and cleanups"

       "Bruce has announced he is leaving Red Hat at the end of the month and
        is stepping back from his role as NFSD co-maintainer. As a result,
        this includes a patch removing him from the MAINTAINERS file.
      
        There is one patch in here that Jeff Layton was carrying in the locks
        tree. Since he had only one for this cycle, he asked us to send it to
        you via the nfsd tree.
      
        There continues to be 0-day reports from Robert Morris @MIT. This time
        we include a fix for a crash in the COPY_NOTIFY operation.
      
        Highlights:
         - Bruce steps down as NFSD maintainer
         - Prepare for dynamic nfsd thread management
         - More work on supporting re-exporting NFS mounts

      perf record: Disable debuginfod by default · 9bce13ea
      Jiri Olsa authored
      Fedora 35 sets DEBUGINFOD_URLS by default, which might lead to
      unexpected stalls in perf record exit path, when we try to cache
      profiled binaries.
      
        # DEBUGINFOD_PROGRESS=1 ./perf record -a
        ^C[ perf record: Woken up 1 times to write data ]
        Downloading from https://debuginfod.fedoraproject.org/ 447069
        Downloading from https://debuginfod.fedoraproject.org/ 1502175
        Downloading \^Z
      
      Disabling DEBUGINFOD_URLS by default in perf record and adding
      debuginfod option and .perfconfig variable support to enable id.
      
        Default without debuginfo processing:
        # perf record -a
      
        Using system debuginfod setup:
        # perf record -a --debuginfod
      
        Using custom debuginfd url:
        # perf record -a --debuginfod='https://evenbetterdebuginfodserver.krava'
      
      Adding single perf_debuginfod_setup function and using
      it also in perf buildid-cache command.

      Needed to check if a cpu_map is dummy, i.e. not a cpu map at all, for

      This probably needs to move to libperf, but since perf itself is the
      first and so far only user, leave it at tools/perf/util/.

      perf metric: Fix metric_leader · d3e2bb43
      Ian Rogers authored
      Multiple events may have a metric_leader to aggregate into.
      
      This happens for uncore events where, for example, uncore_imc is
      expanded into uncore_imc_0, uncore_imc_1, etc.
      
      Such events all have the same metric_id and should aggregate into the
      first event.
      
      The change introducing metric_ids had a bug where the metric_id was
      compared to itself, creating an always true condition.
      
      Correct this by comparing the event in the metric_evlist and the
      metric_leader.
      
      Fixes: ec5c5b3d ("perf metric: Encode and use metric-id as qualifier")
