#     Merge tag 'perf-tools-fixes-for-v6.0-2022-09-29' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux
#     
#     Pull perf tools fixes from Arnaldo Carvalho de Melo:
#     
#      - Fail the 'perf test record' entry on error, fixing a regression where
#        just setup stuff like allocating memory and not the actual things
#        being tested failed.
#     
#      - Fixup disabling of -Wdeprecated-declarations for the python scripting
#        engine, the previous attempt had a brown paper bag thinko.
#     
#      - Fix branch stack sampling test to include sanity check for branch
#        filter on PowerPC.
#     
#      - Update is_ignored_symbol function to match the kernel ignored list,
#        fixing running the 'perf test' entry that compares resolving symbols
#        from kallsyms to resolving from vmlinux.
#     
#      - Augment the data source type with ARM's neoverse_spe list, the
#        previous code was limited in its search resolving the data source.
#     
#      - Fix some clang 5 variable set but unused cases.
#     
#      - Get a perf cgroup more portably in BPF as the
#        __builtin_preserve_enum_value builtin is not available in older
#        versions of clang. In those cases we can forgo BPF's CO-RE (Compile
#        Once, Run Everywhere).
#     
#      - More Fixes for Intel's hybrid CPU model.
