#     Merge tag 'perf-tools-for-v5.17-2022-01-22' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux
#     
#     Pull more perf tools updates from Arnaldo Carvalho de Melo:
#     
#      - Fix printing 'phys_addr' in 'perf script'.
#     
#      - Fix failure to add events with 'perf probe' in ppc64 due to not
#        removing leading dot (ppc64 ABIv1).
#     
#      - Fix cpu_map__item() python binding building.
#     
#      - Support event alias in form foo-bar-baz, add pmu-events and
#        parse-event tests for it.
#     
#      - No need to setup affinities when starting a workload or attaching to
#        a pid.
#     
#      - Use path__join() to compose a path instead of ad-hoc snprintf()
#        equivalent.
#     
#      - Override attr->sample_period for non-libpfm4 events.
#     
#      - Use libperf cpumap APIs instead of accessing the internal state
#        directly.
#     
#      - Sync x86 arch prctl headers and files changed by the new
#        set_mempolicy_home_node syscall with the kernel sources.
#     
#      - Remove duplicate include in cpumap.h.
#     
#      - Remove redundant err variable.
