       - Avoid SEGV if core.cpus isn't set in 'perf stat'.
      
       - Stop depending on .git files for building PERF-VERSION-FILE, used in
         'perf --version', fixing some perf tools build scenarios.
      
       - Convert tracepoint.py example to python3.
      
       - Update UAPI header copies from the kernel sources: socket,
         mman-common, msr-index, KVM, i915 and cpufeatures.
      
       - Update copy of libbpf's hashmap.c.
      
       - Directly return instead of using local ret variable in
         evlist__create_syswide_maps(), found by coccinelle.

      This log message was accidentally chopped off.
      
      I was wondering why this happened, but checking the ML log, Mark
      precisely followed my suggestion [1].
      
      I just used "..." because I was too lazy to type the sentence fully.
      Sorry for the confusion.
