ftrace updates for tip

Ingo,

Here's some more ftrace updates.

The first should help fix the bug in lockdep.

The next are changes to the ring buffer to get ready to have it work with splice.

The last are some clean ups for function graph.

The following patches are in:

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

Steven Rostedt (5):
ftrace: replace raw_local_irq_save with local_irq_save
ring-buffer: move some metadata into buffer page
ring-buffer: read page interface
ftrace: clean up function graph asm
ftrace: have function graph use mcount caller address
