Add support to dump SRQ resource in raw format. It enable drivers to
return the entire device specific SRQ context without setting each
field separately.

Example:
$ rdma res show srq -r
dev hns3 149000...

$ rdma res show srq -j -r
[{"ifindex":0,"ifname":"hns3","data":[149,0,0,...]}]

If, for any reason, the open-coded arithmetic causes a wraparound,
the protection that `struct_size()` provides against potential integer
overflows is defeated. Fix this by hardening calls to `struct_size()`
with `size_add()`, `size_sub()` and `size_mul()`.

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.

   - Update scale units and descriptions of common topdown metrics on
     aarch64. Things like:
       - "MetricExpr": "stall_slot_frontend / (#slots * cpu_cycles)",
       - "BriefDescription": "Frontend bound L1 topdown metric",
       + "MetricExpr": "100 * (stall_slot_frontend / (#slots * cpu_cycles))",
       + "BriefDescription": "This metric is the percentage of total slots that were stalled due to resource constraints in the frontend of the processor.",

   - Update events for intel: meteorlake to 1.04, sapphirerapids to
     1.15, Icelake+ metric constraints.

   - Update files for the power10 platform"

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.

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.

Merge tag 'driver-core-6.6-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

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"

This reverts commit d5af729d.

d5af729d ("PCI: Mark NVIDIA T4 GPUs to avoid bus reset") avoided
Secondary Bus Reset on the T4 because the reset seemed to not work when the
T4 was directly attached to a Root Port.

But NVIDIA thinks the issue is probably related to some issue with the Root
Port, not with the T4.  The T4 provides neither PM nor FLR reset, so
masking bus reset compromises this device for assignment scenarios.

Revert d5af729d as requested by Wu Zongyong.  This will leave SBR
broken in the specific configuration Wu tested, as it was in v6.5, so Wu
will debug that further.
