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

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).

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
