Using Linus's master is usually fine, but if you want to see what I'm
working on, just look at the ftrace/core branch of my linux-trace.git
tree on kernel.org. Note, that branch often rebases. My for-next branch
does not.

Also note, I'm currently looking to pull in Tom Zanussi's hist patch
series, and then I'll get to yours afterward.
