Hi Thomas, Sorry to bother you. I am always wondering what's the difference between x86_cpu_to_apicid and x86_bios_cpu_apicid. Or in other words, I don't know why x86_bios_cpu_apicid is required. From code both x86_cpu_to_apicid and x86_bios_cpu_apicid stores the apicid correspond to a certain logic cpu number. With my understanding x86_cpu_to_apicid can do what x86_bios_cpu_apicid is doing except for its usage in below commit.
