function calls from identify_cpu()

[Kevin Diggs]

I added:

int __init iDoNothingUseful(struct cpu_spec *s,struct cpu_spec *t)
{
        return s-t;
}
right before the definition of identify_cpu() in cputable.c and:

//                      (void) (*PTRRELOC(&iDoNothingUseful))(s,t);
                        (void) iDoNothingUseful(s,t);

right before the return s; in the match block and it will not boot? Can 
someone please explain what might be going on?

Thanks!
