I confirmed this series can apply cleanly on the branch [1] with the
latest commit 150dab31d560 ("perf disasm: Fix not cleaning up
disasm_line in symbol__disassemble_raw()"):

  [1] https://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools-next.git
      branch: perf-tools-next

If you are suggesting for the branch:

  [2] https://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools.git
      branch: perf-tools

You can see it misses some Arm SPE patches which have been picked up
in the repo [1].

Please kindly suggest what is right thing to do.

Thanks,
Leo
