    ftrace/x86: Add support for C version of recordmcount · 72441cb1
    Steven Rostedt authored
    This patch adds the support for the C version of recordmcount and
    compile times show ~ 12% improvement.
    
    After verifying this works, other archs can add:
    
     HAVE_C_MCOUNT_RECORD
    
    in its Kconfig and it will use the C version of recordmcount
    instead of the perl version.
