[GIT PULL] tracing updates for 2.6.32

[Frederic Weisbecker]

Hi Ingo, Thomas,

Here are some fixes and enhancements for the 2.6.32 tracing tree.

Impacts:

- A spurious warning in the lockless ring buffer had been shutdown
- Simplifications of various ftrace code areas resulting in more deletions than
  additions.

These changes have been based against tip:tracing/core

Thanks,

Frederic.
