     option

  aarch64 hw tracing support:
   - Decode memory tagging properties
   - Improve ARM's auxtrace support
   - Add support for ARMv8.3-SPE

  perf kvm:

  perf stat:
   - Add --quiet option

  Cleanups:
   - Fixup function names wrt what is in libperf and what is in
     tools/perf

  Build:
   - Allow building without libbpf in older systems

  New kernel features:
   - Initial support for data/code page size sample type, more to come

  perf annotate:
   - Support MIPS instruction extended support

  perf stack unwinding:
   - Fix separate debug info files when using elfutils' libdw's unwinder

  perf vendor events:
   - Update Intel's Skylake client events to v50
   - Add JSON metrics for ARM's imx8mm DDR Perf
   - Support printing metric groups for system PMUs

  perf build id:
   - Prep work for supporting having the build id provided by the kernel
     in PERF_RECORD_MMAP2 metadata events

  perf stat:
   - Support regex pattern in --for-each-cgroup

  pipe mode:
   - Allow to use stdio functions for pipe mode
   - Support 'perf report's' --header-only for pipe mode
   - Support pipe mode display in 'perf evlist'

  Documentation:
