Is there a way to blacklist a single place where one of these is
inlined? I don't think blacklisting the offending function where these
are inlined would prevent the crash with 'probe
kernel.function("hash_64") {}'. Or would it?

After some testing with 3.2.0 and .call, only these two functions have
caused crashes so far (in KVM):

* inat_get_opcode_attribute
* native_set_debugreg

The first of these is already included in the blacklist of systemtap
git HEAD, but the second one is new.
