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. * tag 'perf-tools-for-v5.17-2022-01-22' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux: perf tools: Remove redundant err variable perf test: Add parse-events test for aliases with hyphens perf test: Add pmu-events test for aliases with hyphens perf parse-events: Support event alias in form foo-bar-baz perf evsel: Override attr->sample_period for non-libpfm4 events perf cpumap: Remove duplicate include in cpumap.h perf cpumap: Migrate to libperf cpumap api perf python: Fix cpu_map__item() building perf script: Fix printing 'phys_addr' failure issue tools headers UAPI: Sync files changed by new set_mempolicy_home_node syscall tools headers UAPI: Sync x86 arch prctl headers with the kernel sources perf machine: Use path__join() to compose a path instead of snprintf(dir, '/', filename) perf evlist: No need to setup affinities when disabling events for pid targets perf evlist: No need to setup affinities when enabling events for pid targets perf stat: No need to setup affinities when starting a workload perf affinity: Allow passing a NULL arg to affinity__cleanup() perf probe: Fix ppc64 'perf probe add events failed' case
