Fix the following DeprecationWarning: tools/perf/util/setup.py:31: DeprecationWarning: The distutils package is deprecated and slated for removal in Python 3.12. Use setuptools or check PEP 632 for potential alternatives Note: the setuptools module may need installing, for example: $ sudo apt install python-setuptools Reviewer comments: James said: Tested it with python 2.7 and 3.8 by running "make install-python_ext PYTHON=..." Committer notes: Tested with: $ make -k BUILD_BPF_SKEL=1 PYTHON=python3 O=/tmp/build/perf -C tools/perf install-bin ; perf test python $ make -k BUILD_BPF_SKEL=1 O=/tmp/build/perf -C tools/perf install-bin ; perf test python Reviewed-by: James Clark <james.clark@arm.com> Signed-off-by: Ian Rogers <irogers@google.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: https://lore.kernel.org/r/20220615014206.26651-1-irogers@google.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
