--- Comment #7 from David Smith <dsmith at redhat dot com> ---
I found an aarch64 machine I could access
(running3.13.0-0.rc7.31.sa2.k32v1.aarch64.debug), built, installed, and got the
following:
====
# stap -p4 -e 'probe syscall.* { log("hey!"); exit() }'

So that looks like a kernel problem, not a systemtap problem.
On your kernel, something odd is going on if things like __NR_open aren't
defined. Can you try the following patch and see if that fixes things?

// On older kernels (like RHEL5), we have to define our own 32-bit
