tracing/function-return-tracer: call prepare_ftrace_return by registers Impact: Optimize a bit the function return tracer This patch changes the calling convention of prepare_ftrace_return to pass its arguments by register. This will optimize it a bit and prepare it to support dynamic tracing. Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
