Merge tag 'perf-tools-for-v5.15-2021-09-11' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull more perf tools updates from Arnaldo Carvalho de Melo:

 - Add missing fields and remove some duplicate fields when printing a
   perf_event_attr.

 - Fix hybrid config terms list corruption.

 - Update kernel header copies, some resulted in new kernel features
   being automagically added to 'perf trace' syscall/tracepoint argument
   id->string translators.

 - Add a file generated during the documentation build to .gitignore.

 - Add an option to build without libbfd, as some distros, like Debian
   consider its ABI unstable.

 - Add support to print a textual representation of IBS raw sample data
   in 'perf report'.

 - Fix bpf 'perf test' sample mismatch reporting

 - Fix passing arguments to stackcollapse report in a 'perf script'
   python script.

 - Allow build-id with trailing zeros.

 - Look for ImageBase in PE file to compute .text offset.
