tracing: move utility functions from ftrace.h to kernel.h
Make common utility functions such as trace_printk() and tracing_start()/tracing_stop() generally available to kernel code. Cc: Steven Rostedt <srostedt@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

- * Note: __trace_printk is an internal function for trace_printk and

- *
- * This function allows a kernel developer to debug fast path sections

- * where problems are occurring.
- *
- * This is intended as a debugging tool for the developer only.
