Merge tag 'perf-tools-fixes-for-v6.0-2022-08-27' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull perf tools fixes from Arnaldo Carvalho de Melo:

 - Fixup setup of weak groups when using 'perf stat --repeat', add a
   'perf test' for it.

 - Fix memory leaks in 'perf sched record' detected with
   -fsanitize=address.

 - Fix build when PYTHON_CONFIG is user supplied.

 - Capitalize topdown metrics' names in 'perf stat', so that the output,
   sometimes parsed, matches the Intel SDM docs.

 - Make sure the documentation for the save_type filter about Intel
   systems with Arch LBR support (12th-Gen+ client or 4th-Gen Xeon+
   server) reflects recent related kernel changes.

 - Fix 'perf record' man page formatting of description of support to
   hybrid systems.

 - Update arm64´s KVM header from the kernel sources.
