ACPI specification r6.4 introduced the Multiprocessor Wakeup Structure to let the bootstrap processor wake up application processors with a mailbox.

This PR follows the design and definition of ACPI specification and has been verified in my project.

Thanks - this is organisationally good to go, just one remaining point re volatile writes to the mailbox.

The issue has been fixed. Thanks for your comments. @IsaacWoods
