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"
