    Linus Torvalds authored
    Pull more perf tools updates from Arnaldo Carvalho de Melo:
     "Fixes:
       - Fixes for 'perf bench numa'.
    
       - Always memset source before memcpy in 'perf bench mem'.
    
       - Quote CC and CXX for their arguments to fix build in environments
         using those variables to pass more than just the compiler names.
    
       - Fix module symbol processing, addressing regression detected via
         "perf test".
    
       - Allow multiple probes in record+script_probe_vfs_getname.sh 'perf
         test' entry.
    
      Improvements:
       - Add script to autogenerate socket family name id->string table from
         copy of kernel header, used so far in 'perf trace'.
    
       - 'perf ftrace' improvements to provide similar options for this
         utility so that one can go from 'perf record', 'perf trace', etc to
         'perf ftrace' just by changing the name of the subcommand.
    
       - Prefer new "sched:sched_waking" trace event when it exists in 'perf
         sched' post processing.
    
       - Update POWER9 metrics to utilize other metrics.
    
       - Fall back to querying debuginfod if debuginfo not found locally.
    
      Miscellaneous:
       - Sync various kvm headers with kernel sources"
