- * cpu_mp_start() will be called so that MP can be enabled.  This function

- * cpu_mp_announce() will be called so that machine dependent messages about
- * the MP support may be output to the console if desired.
- *
- * The cpu_setmaxid() function is called very early during the boot process
- * so that the MD code may set mp_maxid to provide an upper bound on CPU IDs
- * that other subsystems may use.  If a platform is not able to determine
- * the exact maximum ID that early, then it may set mp_maxid to MAXCPU - 1.
