ftrace: updates for tip

Ingo,

Most of thes patches are improvements to function graph. I'm working on making a way to pick a function to trace, which the patch function entry patch is needed.

The one ring buffer patch converts all variables called 'page' to 'bpage' as per Andrew's request.

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 ftrace_graph_stop
ring-buffer: change page variables to bpage
ftrace: print real return in dumpstack for function graph
ftrace: function graph return for function entry
ftrace: add checks on ret stack in function graph
