Regardless of if this is fixed, I'm not convinced this is something we
want to merge. After all, a process executed a syscall and we should
process it like any other; just because it happens to be an
unrecognized syscall on a particular kernel build doesn't mean it
isn't security relevant (probing for specific syscall numbers may be a
useful attack fingerprint).
