working version of a patch

Funnily, I'm still a bit lost in this problem.  Attached patch demonstrates

=3D=3D=3D=3D=3D=3D=3D
$ stap  -e 'probe process("./a.out").function("set2").return { println($y->=
x)
}' -c './a.out > /dev/null' -p2 > /dev/null
WARNING: WARN WARN WARN
$ stap  -e 'probe process("./a.out").function("set2").return {
println(@entry($y->x)) }' -c './a.out > /dev/null' -p2 > /dev/null
$
