Merge tag 'perf-tools-fixes-for-v5.18-2022-04-22' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux
Pull perf tools fixes from Arnaldo Carvalho de Melo: - Fix header include for LLVM >= 14 when building with libclang. - Allow access to 'data_src' for auxtrace in 'perf script' with ARM SPE perf.data files, fixing processing data with such attributes. - Fix error message for test case 71 ("Convert perf time to TSC") on s390, where it is not supported. * tag 'perf-tools-fixes-for-v5.18-2022-04-22' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux: perf test: Fix error message for test case 71 on s390, where it is not supported perf report: Set PERF_SAMPLE_DATA_SRC bit for Arm SPE event perf script: Always allow field 'data_src' for auxtrace perf clang: Fix header include for LLVM >= 14
