Seems to be installed by default on the current image, but this seems more future-proof.

606580c05d announce that a cpu is online in the apic code 
=> move code from main.c to apic.c, because the time of announcement
   depends on the boot process. (The multi- and the single-kernel
   version of HermitCore use a different boot process.)

6d8d6ee2ad Add description to the standalone version of HermitCore
