Merge tag 'perf-tools-fixes-for-v5.19-2022-06-19' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux
Pull perf tool fixes from Arnaldo Carvalho de Melo:
- Don't set data source if it's not a memory operation in ARM SPE
(Statistical Profiling Extensions).
- Fix handling of exponent floating point values in perf stat
expressions.
- Don't leak fd on failure on libperf open.
- Fix 'perf test' CPU topology test for PPC guest systems.
- Fix undefined behaviour on breakpoint account 'perf test' entry.
- Record only user callchains on the "Check ARM64 callgraphs are
complete in FP mode" 'perf test' entry.
- Fix "perf stat CSV output linter" test on s390.
- Sync batch of kernel headers with tools/perf/.
