Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf updates from Thomas Gleixner: "Perf updates and fixes: Kernel: - Handle events which have the bpf_event attribute set as side band events as they carry information about BPF programs. - Add missing switch-case fall-through comments Libraries: - Fix leaks and double frees in error code paths. - Prevent buffer overflows in libtraceevent Tools: - Improvements in handling Intel BT/PTS - Add BTF ELF markers to perf trace BPF programs to improve output - Support --time, --cpu, --pid and --tid filters for perf diff - Calculate the column width in perf annotate as the hardcoded 6 characters for the instruction are not sufficient - Small fixes all over the place" * 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (38 commits) perf/core: Mark expected switch fall-through perf/x86/intel/uncore: Fix client IMC events return huge result perf/ring_buffer: Use high order allocations for AUX buffers optimistically perf data: Force perf_data__open|close zero data->file.path perf session: Fix double free in perf_data__close perf evsel: Probe for precise_ip with simple attr perf tools: Read and store caps/max_precise in perf_pmu perf hist: Fix memory leak of srcline perf hist: Add error path into hist_entry__init perf c2c: Fix c2c report for empty numa node perf script python: Add Python3 support to intel-pt-events.py perf script python: Add Python3 support to event_analyzing_sample.py perf script python: add Python3 support to check-perf-trace.py perf script python: Add Python3 support to futex-contention.py perf script python: Remove mixed indentation perf diff: Support --pid/--tid filter options perf diff: Support --cpu filter option perf diff: Support --time filter option perf thread: Generalize function to copy from thread addr space from intel-bts code perf annotate: Calculate the max instruction name, align column to that ...
