#     Merge tag 'perf-tools-fixes-for-v5.13-2021-05-24' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux
#     
#     Pull perf tool fixes from Arnaldo Carvalho de Melo:
#     
#      - Fix 'perf script' decoding of Intel PT traces for abort handling and
#        sample instruction bytes.
#     
#      - Add missing PERF_IP_FLAG_CHARS for VM-Entry and VM-Exit to Intel PT
#        'perf script' decoder.
#     
#      - Fixes for the python based Intel PT trace viewer GUI.
#     
#      - Sync UAPI copies (unwire quotactl_path, some comment fixes).
#     
#      - Fix handling of missing kernel software events, such as the recently
#        added 'cgroup-switches', and add the trivial glue for it in the
#        tooling side, since it was added in this merge window.
#     
#      - Add missing initialization of zstd_data in 'perf buildid-list',
#        detected with valgrind's memcheck.
#     
#      - Remove needless event enable/disable when all events uses BPF.
#     
#      - Fix libpfm4 support (63) test error for nested event groups.
