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.
