This is a known problem. See:
<http://sources.redhat.com/ml/systemtap/2006-q3/msg00637.html>
Bibo Mao volunteered to add kernel patches for the 3 problem areas I found.
Here's the specific one for atomic_notifier_call_chain(), which marks it with
"__kprobes":
<http://www.ussg.iu.edu/hypermail/linux/kernel/0609.3/0589.html>
A problem we have is that atomic_notifier_call_chain() has been marked as
"__kprobes" in the upstream kernel, but hasn't made it to a released kernel from
my understanding (by either kernel.org or a vendor).
I have no problem with adding "atomic_notifier_call_chain" to the blacklist in
the meantime.
