function::regparm - Specify regparm value used to compile function

n
           original regparm value

       Call this function with argument n before accessing function arguments using the *_arg function is the
       function was build with the gcc -mregparm=n option.

       (The i386 kernel is built with \-mregparm=3, so systemtap considers regparm(3) the default for kernel
       functions on that architecture.) Only valid on i386 and x86_64 (when probing 32bit applications).
       Produces an error on other architectures.
