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.
