#     
#     Pull perf tools fixes from Arnaldo Carvalho de Melo:
#     
#      - Fix SMT detection fast read path on sysfs.
#     
#      - Fix memory leaks when processing feature headers in perf.data files.
#     
#      - Fix 'Simple expression parser' 'perf test' on arch without CPU die
#        topology info, such as s/390.
#     
#      - Fix building perf with BUILD_BPF_SKEL=1.
#     
#      - Fix 'perf bench' by reverting "perf bench: Fix two memory leaks
#        detected with ASan".
#     
#      - Fix itrace space allowed for new attributes in 'perf script'.
#     
#      - Fix the build feature detection fast path, that was always failing on
#        systems with python3 development packages, speeding up the build.
#     
#      - Reset shadow counts before loading, fixing metrics using
#        duration_time.
#     
#      - Sync more kernel headers changed by the new futex_waitv syscall: s390
#        and powerpc.
