Subject: [PATCH -tip 0/2] kprobes/x86: RO text code bugfix and cleanup

Hi,

This series fixes a kprobe-x86 bug related to RO text and
cleans up addressof operators.

The first one is an obvious bug that misses to set memory
RO when the function fails. I've just add set_memory_ro()
on error exit.

And the second one is just a cleanup patch to remove
addressof operators ("&") since it is meaningless anymore.

Please apply these, since this series is independent from
another bugfix related to optprobe discussing in other
thread.

Thanks,

---
