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.

x86/topology: Create logical package id
Could you please help to explain when it's convenient to you?
Thanks
Baoquan
