Subject: [PATCH 00/16] [GIT PULL] tracing: fixes/cleanups, no stop-machine, update stack tracer

Ingo,

This patch set contains a few things.

1) various fixes and cleanups, one is even marked as stable, but its
   a minor bug fix that probably is not worth pushing to mainline this
   late in the -rc.

2) The infrastructure to use ftrace function tracing without stop_machine.
  Although x86 doesn't have the iret code finished to do this yet,
  other archs like PPC can. This will also test out the code better.
  Note, it's just a single patch left that converts x86 to use this code.

3) Moving the stack tracer to its own function list. As Jiri is
   working on having perf do function tracing, he found a few bugs
   that were hard to find without another user outside the global users.
   It makes sense to have the stack tracer separate from the function
   tracer anyway, and it gives a good test bed for perf and function
   tracing as well.
