#     
#     Pull perf tools fixes from Arnaldo Carvalho de Melo:
#     
#      - Set PERF_SAMPLE_PERIOD if attr->freq is set.
#     
#      - Remove trailing commas from AMD JSON vendor event files.
#     
#      - Don't clear event's period if set by a event definition term.
#     
#      - Leader sampling shouldn't clear sample period in 'perf test'.
#     
#      - Fix the "signal" test inline assembly when built with DEBUG=1.
#     
#      - Fix memory leaks detected by ASAN, some in normal paths, some in
#        error paths.
#     
#      - Fix 2 memory sanitizer warnings in 'perf bench'.
#     
#      - Fix the ratio comments of miss-events in 'perf stat'.
#     
#      - Prevent override of attr->sample_period for libpfm4 events.
#     
#      - Sync kvm.h and in.h headers with the kernel sources.
