This patch set introduces tracepoints for SMC, including the tracepoints basic code. The tracepoitns would help us to track SMC's behaviors by automatic tools, or other BPF tools, and zero overhead if not enabled. Compared with kprobe and other dymatic tools, the tracepoints are considered as stable API, and less overhead for tracing with easy-to-use API.
