Merge tag 'perf-tools-fixes-for-v6.16-1-2025-06-20' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools

Pull perf tools fixes from Arnaldo Carvalho de Melo:

 - Fix some file descriptor leaks that stand out with recent changes to
   'perf list'

 - Fix prctl include to fix building 'perf bench futex' hash with musl
   libc

 - Restrict 'perf test' uniquifying entry to machines with 'uncore_imc'
   PMUs

 - Document new output fields (op, cache, mem, dtlb, snoop) used with
   'perf mem'

 - Synchronize kernel header copies
