Hi Steven,

Here, I'd like to push updates of dynamic events and perf-probe
for supporting dynamic events on module.

The main part of this series is 1-5th patches for kprobes and
dynamic event tracer, which allows us to add events on offline
kernel module. This means we can put events even on the init
functions of the drivers before loading. The requirement of
this feature comes from my recent experience of a driver
debugging. It had a timing bug in the initialization routine,
and it was hard to catch them without tracing the behavior.

I added some perf-probe updates (which including some resent
patches), And it's OK to pull only the main part (kprobes and
ftrace patches) without perf updates.


Thank you,

---
