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/. * tag 'perf-tools-fixes-for-v5.19-2022-06-19' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux: tools headers UAPI: Sync linux/prctl.h with the kernel sources perf metrics: Ensure at least 1 id per metric tools headers arm64: Sync arm64's cputype.h with the kernel sources tools headers UAPI: Sync x86's asm/kvm.h with the kernel sources perf arm-spe: Don't set data source if it's not a memory operation perf expr: Allow exponents on floating point values perf test topology: Use !strncmp(right platform) to fix guest PPC comparision check perf test: Record only user callchains on the "Check Arm64 callgraphs are complete in fp mode" test perf beauty: Update copy of linux/socket.h with the kernel sources perf test: Fix variable length array undefined behavior in bp_account libperf evsel: Open shouldn't leak fd on failure perf test: Fix "perf stat CSV output linter" test on s390 perf unwind: Fix uninitialized variable
