#     Merge tag 'perf-tools-fixes-for-v5.14-2021-08-01' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux
#     
#     Pull perf tools fixes from Arnaldo Carvalho de Melo:
#     
#      - Revert "perf map: Fix dso->nsinfo refcounting", this makes 'perf top'
#        abort, uncovering a design flaw on how namespace information is kept.
#        The fix for that is more than we can do right now, leave it for the
#        next merge window.
#     
#      - Split --dump-raw-trace by AUX records for ARM's CoreSight, fixing up
#        the decoding of some records.
#     
#      - Fix PMU alias matching.
#     
#     Thanks to James Clark and John Garry for these fixes.
