+//! Multi-Processor Services Protocol
+//!
+//! This Protocol is defined in the UEFI Platform Integration Specification,
+//! Section 13.4.
+//!
+//! This provides a generalized way of performing the following tasks:
+//! - Retrieving information of multi-processor environments.
+//! - Dispatching user-provided function to APs.
+//! - Maintain MP-related processor status.
