NR_CPUS是与多处理相关的宏定义，表示CPU的个数。如果定义了CONFIG_SMP那么取CONFIG_NR_CPUS，否则取1。

873 - 设置 nr_cpu_ids 这个变量,表示真实存在的 possible cpus 。因为前面setup_arch 里面已经根据 dtb ,知道了设备的 cpu 信息。 874 - setup_pre_cpu_areas ,为每一个cpu , 设置 per cpu 变量存储空间 。 875 smp_prepare_boot_cpu , 将 boot cpu 的 信息 存储在 per cpu 变量 cpu_data 里面。
Hardcoding the number of CPUs at compile time does improve code generation, but if you get it wrong the result will be confusion. We already limited this earlier to only "experts" (see commit fe5759d "cpumask: limit visibility of FORCE_NR_CPUS"), but with distro kernel configs often hav...
