missing entrypc dwarf line record

Hi-
In testing in s390x I found the following tap script is producing this 
error.

jpr.stp:
probe kernel.function("jprobe_return") {}

stap -p4 -vv jpr.stp

Pass 1: parsed user script and 47 library script(s) in 
990usr/30sys/1042real ms.
semantic error: missing entrypc dwarf line record for function 
'jprobe_return'
semantic error: no match for probe point
while: resolving probe point kernel.function("jprobe_return")

jprobe_return is black-listed but it is not helping..

void __kprobes jprobe_return(void)
{
        asm volatile (".word 0x0002");
}

Any hints on how to fix this one?
