#     Pull perf tools fixes from Arnaldo Carvalho de Melo:
#      "Perf tool fixes:
#     
#        - Fix wrong skipping for per-die aggregation in 'perf stat'.
#     
#        - Fix race in signal handling on large core count machines, setting
#          up signal handlers earlier.
#     
#        - Fix -F for branch & mem modes in 'perf report'.
#     
#        - Fix the condition checks for max number of NUMA nodes in 'perf
#          bench numa'.
#     
#        - Fix crash in 'perf diff' error path.
#     
#        - Fix filtering of empty build-ids in 'perf archive'.
#     
#        - Ensure read cmdlines from libtraceevent are null terminated.
#     
#       Recent regressions:
#     
#        - Fix control fifo permissions in 'perf daemon'.
#     
#        - Fix 'perf daemon' compile error with ASAN.
#     
#        - Fix running 'perf daemon' test for non root user.
#     
#        - Fix PERF_SAMPLE_WEIGHT_STRUCT 'perf test' failure on non-x86
#          arches.
#     
#        - Fix event's PMU name parsing related to new drm/i915/gt
#          software-gt-awake-time event.
#     
#       Fixes from compiler instrumentation:
#     
#        - Fix leaks in 'perf test' entries, found using ASAN.
#     
#        - Fix use-after-free when 'perf stat -r' option is used.
#     
#       Arch specific:
#     
#        - Fix bitmap for option om ARM's CS-ETM.
#     
#       Documentation:
#     
#        - Fix documentation of verbose options.
#     
#       Build:
#     
#        - Clean 'generated' directory used for creating the syscall table on
#          x86.
#     
#        - Fix ccache usage in $(CC) when generating arch errno table.
#     
#        - Cast (struct timeval).tv_sec when printing, fixing the build with
#          MUSL libc.
#     
#        - Tighten snprintf() string precision to pass gcc check on some
#          32-bit arches.
#     
#        - Update UAPI copies from the kernel sources.
#     
#        - Fix regression on feature detection 'make clean' target"
