tracing: updates and fixes for 3.10

This set of patches mostly consists of fixes for 3.10. I'm posting this and putting it into linux-next for a few days before asking Linus to pull.

I'll probably add a few more patches to linux-next as well, as there's a few more bugs that have been discovered lately.
