|void process_utils::create_initial_system_process().  
 |Called to start the first userspace process, which is normally "sys_init_osd.self" but it can also launch recovery mode or update mode.

|void Panic(int unk)  
|This function does not return. 
(It seems that the offset point to a location that will cause panic after, not the real panic function, use with caution)
