      Pull drm ci scripts from Dave Airlie:
       "This is a bunch of ci integration for the freedesktop gitlab instance
        where we currently do upstream userspace testing on diverse sets of
        GPU hardware. From my perspective I think it's an experiment worth
        going with and seeing how the benefits/noise playout keeping these
        files useful.
      
        Ideally I'd like to get this so we can do pre-merge testing on PRs
        eventually.
      
        Below is some info from danvet on why we've ended up making the
        decision and how we can roll it back if we decide it was a bad plan.
      
        Why in upstream?
      
         - like documentation, testcases, tools CI integration is one of these
           things where you can waste endless amounts of time if you
           accidentally have a version that doesn't match your source code
      
         - but also like the above, there's a balance, this is the initial cut
           of what we think makes sense to keep in sync vs out-of-tree,
           probably needs adjustment
      
         - gitlab supports out-of-repo gitlab integration and that's what's
           been used for the kernel in drm, but it results in per-driver
           fragmentation and lots of duplicated effort. the simple act of
           smashing an arbitrary winner into a topic branch already started
           surfacing patches on dri-devel and sparking good cross driver team
           discussions
      
        Why gitlab?
      
         - it's not any more shit than any of the other CI
      
         - drm userspace uses it extensively for everything in userspace, we
           have a lot of people and experience with this, including
           integration of hw testing labs
      
         - media userspace like gstreamer is also on gitlab.fd.o, and there's
           discussion to extend this to the media subsystem in some fashion
      
        Can this be shared?
      
         - there's definitely a pile of code that could move to scripts/ if
           other subsystem adopt ci integration in upstream kernel git. other
           bits are more drm/gpu specific like the igt-gpu-tests/tools
           integration
      
         - docker images can be run locally or in other CI runners
      
        Will we regret this?
      
         - it's all in one directory, intentionally, for easy deletion
      
         - probably 1-2 years in upstream to see whether this is worth it or a
           Big Mistake. that's roughly what it took to _really_ roll out solid
           CI in the bigger userspace projects we have on gitlab.fd.o like
           mesa3d"

      Pull perf tools updates from Arnaldo Carvalho de Melo:
       "perf tools maintainership:
      
         - Add git information for perf-tools and perf-tools-next trees and
           branches to the MAINTAINERS file. That is where development now
           takes place and myself and Namhyung Kim have write access, more
           people to come as we emulate other maintainer groups.
      
        perf record:
      
         - Record kernel data maps when 'perf record --data' is used, so that
           global variables can be resolved and used in tools that do data
           profiling.
      
        perf trace:
      
         - Remove the old, experimental support for BPF events in which a .c
           file was passed as an event: "perf trace -e hello.c" to then get
           compiled and loaded.
      
           The only known usage for that, that shipped with the kernel as an
           example for such events, augmented the raw_syscalls tracepoints and
           was converted to a libbpf skeleton, reusing all the user space
           components and the BPF code connected to the syscalls.
      
           In the end just the way to glue the BPF part and the user space
           type beautifiers changed, now being performed by libbpf skeletons.
      
           The next step is to use BTF to do pretty printing of all syscall
           types, as discussed with Alan Maguire and others.
      
           Now, on a perf built with BUILD_BPF_SKEL=1 we get most if not all
           path/filenames/strings, some of the networking data structures,
           perf_event_attr, etc, i.e. systemwide tracing of nanosleep calls
           and perf_event_open syscalls while 'perf stat' runs 'sleep' for 5

        perf annotate:
      
         - Building with binutils' libopcode now is opt-in (BUILD_NONDISTRO=1)
           for licensing reasons, and we missed a build test on
           tools/perf/tests makefile.
      
           Since we now default to NDEBUG=1, we ended up segfaulting when
           building with BUILD_NONDISTRO=1 because a needed initialization
           routine was being "error checked" via an assert.
      
           Fix it by explicitly checking the result and aborting instead if it
           fails.
      
           We better back propagate the error, but at least 'perf annotate' on
           samples collected for a BPF program is back working when perf is
           built with BUILD_NONDISTRO=1.
      
        perf report/top:
      
         - Add back TUI hierarchy mode header, that is seen when using 'perf
           report/top --hierarchy'.
      
         - Fix the number of entries for 'e' key in the TUI that was
           preventing navigation of lines when expanding an entry.
      
        perf report/script:
      
         - Support cross platform register handling, allowing a perf.data file
           collected on one architecture to have registers sampled correctly
           displayed when analysis tools such as 'perf report' and 'perf
           script' are used on a different architecture.
      
         - Fix handling of event attributes in pipe mode, i.e. when one uses:
      
        	perf record -o - | perf report -i -
      
           When no perf.data files are used.
      
         - Handle files generated via pipe mode with a version of perf and
           then read also via pipe mode with a different version of perf,
           where the event attr record may have changed, use the record size
           field to properly support this version mismatch.
      
        perf probe:
      
         - Accessing global variables from uprobes isn't supported, make the
           error message state that instead of stating that some minimal
           kernel version is needed to have that feature. This seems just a
           tool limitation, the kernel probably has all that is needed.
      
        perf tests:
      
         - Fix a reference count related leak in the dlfilter v0 API where the
           result of a thread__find_symbol_fb() is not matched with an
           addr_location__exit() to drop the reference counts of the resolved
           components (machine, thread, map, symbol, etc). Add a dlfilter test
           to make sure that doesn't regresses.
      
         - Lots of fixes for the 'perf test' written in shell script related
           to problems found with the shellcheck utility.
      
         - Fixes for 'perf test' shell scripts testing features enabled when
           perf is built with BUILD_BPF_SKEL=1, such as 'perf stat' bpf
           counters.
      
         - Add perf record sample filtering test, things like the following
           example, that gets implemented as a BPF filter attached to the
           event:
      
             # perf record -e task-clock -c 10000 --filter 'ip < 0xffffffff00000000'
      
         - Improve the way the task_analyzer test checks if libtraceevent is
           linked, using 'perf version --build-options' instead of the more
           expensinve 'perf record -e "sched:sched_switch"'.
      
         - Add support for riscv in the mmap-basic test. (This went as well
           via the RiscV tree, same contents).
      
        libperf:
      
         - Implement riscv mmap support (This went as well via the RiscV tree,
           same contents).
      
        perf script:
      
         - New tool that converts perf.data files to the firefox profiler
           format so that one can use the visualizer at
           https://profiler.firefox.com/. Done by Anup Sharma as part of this
           year's Google Summer of Code.
      
           One can generate the output and upload it to the web interface but
           Anup also automated everything:
      
             perf script gecko -F 99 -a sleep 60
      
         - Support syscall name parsing on arm64.
      
         - Print "cgroup" field on the same line as "comm".
      
        perf bench:
      
         - Add new 'uprobe' benchmark to measure the overhead of uprobes
           with/without BPF programs attached to it.
      
         - breakpoints are not available on power9, skip that test.
      
        perf stat:
      
         - Add #num_cpus_online literal to be used in 'perf stat' metrics, and
           add this extra 'perf test' check that exemplifies its purpose:
      
        	TEST_ASSERT_VAL("#num_cpus_online",
                               expr__parse(&num_cpus_online, ctx, "#num_cpus_online") == 0);
        	TEST_ASSERT_VAL("#num_cpus", expr__parse(&num_cpus, ctx, "#num_cpus") == 0);
        	TEST_ASSERT_VAL("#num_cpus >= #num_cpus_online", num_cpus >= num_cpus_online);
      
        Miscellaneous:
      
         - Improve tool startup time by lazily reading PMU, JSON, sysfs data.
      
         - Improve error reporting in the parsing of events, passing YYLTYPE
           to error routines, so that the output can show were the parsing
           error was found.
      
         - Add 'perf test' entries to check the parsing of events
           improvements.
      
         - Fix various leak for things detected by -fsanitize=address, mostly
           things that would be freed at tool exit, including:
      
             - Free evsel->filter on the destructor.
      
             - Allow tools to register a thread->priv destructor and use it in
               'perf trace'.
      
             - Free evsel->priv in 'perf trace'.
      
             - Free string returned by synthesize_perf_probe_point() when the
               caller fails to do all it needs.
      
         - Adjust various compiler options to not consider errors some
           warnings when building with broken headers found in things like
           python, flex, bison, as we otherwise build with -Werror. Some for
           gcc, some for clang, some for some specific version of those, some
           for some specific version of flex or bison, or some specific
           combination of these components, bah.
      
         - Allow customization of clang options for BPF target, this helps
           building on gentoo where there are other oddities where BPF targets
           gets passed some compiler options intended for the native build, so
           building with WERROR=0 helps while these oddities are fixed.
      
         - Dont pass ERR_PTR() values to perf_session__delete() in 'perf top'
           and 'perf lock', fixing some segfaults when handling some odd
           failures.
      
         - Add LTO build option.
      
         - Fix format of unordered lists in the perf docs
           (tools/perf/Documentation)
      
         - Overhaul the bison files, using constructs such as YYNOMEM.
      
         - Remove unused tokens from the bison .y files.
      
         - Add more comments to various structs.
      
         - A few LoongArch enablement patches.
      
        Vendor events (JSON):
      
         - Add JSON metrics for Yitian 710 DDR (aarch64). Things like:
      
        	EventName, BriefDescription
        	visible_window_limit_reached_rd, "At least one entry in read queue reaches the visible window limit.",
        	visible_window_limit_reached_wr, "At least one entry in write queue reaches the visible window limit.",
        	op_is_dqsosc_mpc	       , "A DQS Oscillator MPC command to DRAM.",
        	op_is_dqsosc_mrr	       , "A DQS Oscillator MRR command to DRAM.",
        	op_is_tcr_mrr		       , "A Temperature Compensated Refresh(TCR) MRR command to DRAM.",
      
         - Add AmpereOne metrics (aarch64).
      
         - Update N2 and V2 metrics (aarch64) and events using Arm telemetry
           repo.

      iov_iter: Fix iov_iter_extract_pages() with zero-sized entries · f741bd71
      David Howells authored
      iov_iter_extract_pages() doesn't correctly handle skipping over initial
      zero-length entries in ITER_KVEC and ITER_BVEC-type iterators.
      
      The problem is that it accidentally reduces maxsize to 0 when it
      skipping and thus runs to the end of the array and returns 0.
      
      Fix this by sticking the calculated size-to-copy in a new variable
      rather than back in maxsize.

      sh: push-switch: Reorder cleanup operations to avoid use-after-free bug · 246f80a0
      Duoming Zhou authored
      The original code puts flush_work() before timer_shutdown_sync()
      in switch_drv_remove(). Although we use flush_work() to stop
      the worker, it could be rescheduled in switch_timer(). As a result,
      a use-after-free bug can occur. The details are shown below:
      
            (cpu 0)                    |      (cpu 1)
      switch_drv_remove()              |
       flush_work()                    |
        ...                            |  switch_timer // timer
                                       |   schedule_work(&psw->work)
       timer_shutdown_sync()           |
       ...                             |  switch_work_handler // worker
       kfree(psw) // free              |
                                       |   psw->state = 0 // use
      
      This patch puts timer_shutdown_sync() before flush_work() to
      mitigate the bugs. As a result, the worker and timer will be
      stopped safely before the deallocate operations.

      Pull driver symbol lookup fix from Greg KH:
       "Here is one last fixup for your tree for 6.6-rc1. It resolves a
        problem with the way that symbol_get was changed in the module tree
        merge in your tree to fix up the DVB drivers which rely on this old
        api to attach new devices.
      
        As the changelog comment says:
      
          In commit 9011e49d ("modules: only allow symbol_get of
          EXPORT_SYMBOL_GPL modules") the use of symbol_get is properly
          restricted to GPL-only marked symbols. This interacts oddly with the
          DVB logic which only uses dvb_attach() to load the dvb driver which
          then uses symbol_get().
      
          Fix this up by properly marking all of the dvb_attach attach symbols
          as EXPORT_SYMBOL_GPL().
      
        This has been acked by Hans from the V4L driver side, Luis from the
        module side, Mauro on the media side, and Christoph said it was the
        correct solution, and was tested by the original reporter of the
        issue.
      
        It has passed 0-day testing, but has not been in linux-next due to it
        only being sent yesterday"
