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.
