It's not a good description, sorry... We need a entry address and boot up code 
AP. For that purpose, I reuse VCPUOP_initialise and VCPUOP_up hypercall. The 
former guest set the entry address of AP, the later one boot up them. For 
this, I add some code in arch_set_info_guest() to initialize the AP(mostly 
what we did after INIT-SIPI-SIPI sequence), that's what I means here...
