#     Merge tag 'perf-tools-fixes-for-v6.5-1-2023-07-18' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools
#     
#     Pull perf tools fixes from Arnaldo Carvalho de Melo:
#     
#      - Don't group events when computing metrics that require more than the
#        maximum number of simultaneously enabled events on AMD systems.
#     
#      - Fix multi CU handling in 'perf probe', add a 'perf test' entry to
#        regress test it.
#     
#      - Make the 'perf test task_exit' stop generating samples by using the
#        'dummy' event, all it is testing is if a PERF_RECORD_EXIT is
#        generated at the end of a perf session. This makes this perf test to
#        stop sometimes failing on some systems due to a full ring buffer.
#     
#      - Avoid SEGV if PMU lookup fails for legacy cache terms.
#     
#      - Fix libsubcmd SEGV/use-after-free when commands aren't excluded.
#     
#      - Fix OpenCSD (ARM64's CoreSight hardware tracing) library path
#        resolution when specifying CSLIBS= in the make command line.
#     
#      - Fix broken feature check for libtracefs due to external lib changes,
#        use the provided pkgconfig file instead future proof it.
#     
#      - Sync drm, fcntl, kvm, mount, prctl, socket, vhost, asound, arm64's
#        cputype headers with the kernel sources, in some cases this made the
#        tools become aware of new kernel APIs such as ioctls and the
#        cachestat sysctl.
