ftrace: rebase patches on top of tip/master + some extras

Ingo,

Here's my patches rebased against latest tip/master. I also added a couple of goodies at the end to enhance the function-graph tracer.

The first patch is a repost of the set_ftrace_pid, so I am Cc'ing the container guys so they can abuse me some more ;-)

The following patches are in:

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-2.6-trace.git

branch: tip/devel

Steven Rostedt (5):
ftrace: add function tracing to single thread
ftrace: use code patching for ftrace graph tracer
ftrace: let function tracing and function return run together
ftrace: add thread comm to function graph tracer
ftrace: add cpu annotation for function graph tracer
