So you move "adding core1 to cpu_bus" from cpu_bus_scan to amd_sibling_init.

the result will be when you access the cpu_bus and call
amd_sibling_init, the amd_sibling_init will alter the cpu_bus and
append ...cpu on that. So if for 4 way dual core or 8 way dual core,
when disable CPU_INIT_SERIALIZE, if it could cause racing...
