I don't like this. You create this "table" thing, which you use for
tables, and then you go and use it for something else - for kprobes
text which is not a table. The kprobes text section is a section for
text which is not kprobe-able.
So, it seems to be a complete mis-nomer to me. Maybe you can explain
the rationale here?
