Linus,

Namhyung found and fixed another nasty bug, where you can crash the
kernel with: echo 1234 | tee -a /sys/kernel/debug/tracing/set_ftrace_pid

Luckily, only root has permissions to write to that file.

I also added a fix on top of Namhyung's as his patch added a reference
outside of the DYNAMIC_FTRACE to a function that is only defined
in DYNAMIC_FTRACE. This fixes compiling with FUNCTION_TRACING and
without DYNAMIC_FTRACE (although I don't know who does that anymore).
