#     
#     Pull perf tools fixes from Arnaldo Carvalho de Melo:
#      "Only fixes and a sync of the headers so that the perf build is silent:
#     
#        - Fix visibility attribute in python module init code with newer gcc
#     
#        - Fix DRAM_BW_Use 0 issue for CLX/SKX in intel JSON vendor event
#          files
#     
#        - Fix the build on new fedora by removing LTO compiler options when
#          building perl support
#     
#        - Remove broken __no_tail_call attribute
#     
#        - Fix segfault when trying to trace events by cgroup
#     
#        - Fix crash with non-jited BPF progs
#     
#        - Increase buffer size in TUI browser, fixing format truncation
#     
#        - Fix printing of build-id for objects lacking one
#     
#        - Fix byte swapping for ino_generation field in MMAP2 perf.data
#          records
#     
#        - Fix byte swapping for CGROUP perf.data records, for cross arch
#          analysis of perf.data files
#     
#        - Fix the fast path of feature detection
#     
#        - Update kernel header copies"
