Subject: [PATCH 0/3] x86/ftrace: Make created trampolines not call direct code

Peter,

These three patches are built on top of your patch series.

This is what I was thinking of having. This isn't fully tested
(as your patch series is still running on my test suite).

-- Steve


Steven Rostedt (VMware) (3):
      x86/ftrace: Make non direct case the default in ftrace_regs_caller
      x86/ftrace: Only have the builtin ftrace_regs_caller call direct hooks
      x86/ftrace: Do not jump to direct code in created trampolines
