    Well, really any file that references any of those defines should be
    including linux/reboot.h, now - whether a compilation gets errors or
    not. A change in CONFIG options or different platforms/architectures can
    change what file get implictly included.

    See Rule 1 in Documentation/SubmitChecklist.
