[PATCH 0/4] [GIT PULL][RCU][3.12] tracing/rcu: Export strings to userspace

[Steven Rostedt <rostedt@goodmis.org>]

Paul,

As we talked about earlier, I set up a branch based off of v3.11-rc2 which
the first patch has my tracing patch I need for other updates, and
the other three are RCU specific patches that you should take.

You can either just pull this branch from my tree, or you can pull
just the first patch (to keep the same SHA1) and apply the other three
patches any way you want.

I tested all these patches through my standard tests, but I did not run
the RCU ones through any specific RCU tests (like rcutorture). They
shouldn't affect the process of RCU in anyway and only should touch
the way trace points export their strings. You may want to run them through
other tests just to make sure there isn't some strange side effect I
caused. :-)
