I've just merged latest upstream tree into it and pushed
that in a new branch:

git://git.kernel.org/pub/scm/linux/kernel/git/frederic/random-tracing.git
	tracing/kprobes-v2

There were several conflicts, not trivial. I hope I haven't missed
something. But it boots well, I've tested a simple kprobe creation
and fetched its events through perf without any problem.

Thanks,
Frederic.

PS: I'd recommend you to define a name when you define a kprobe.
For example if you want to get the first argument of sys_open,
don't create it using:

	p sys_open a0

but rather:

	p:my_probe_name sys_open a0

Otherwise you will get a default kprobe name that doesn't seem
to make perf trace happy (put in my TODO list).
