 Scheduler initialization

-This is the eighth [part](http://0xax.gitbooks.io/linux-insides/content/Initialization/index.html) of the Linux kernel initialization process and we stopped on the `setup_nr_cpu_ids` function in the [previous](https://github.com/0xAX/linux-insides/blob/master/Initialization/linux-initialization-7.md) part. The main point of the current part is [scheduler](http://en.wikipedia.org/wiki/Scheduling_%28computing%29) initialization. But before we will start to learn initialization process of the scheduler, we need to do some stuff. The next setup in the [init/main.c](https://github.com/torvalds/linux/blob/master/init/main.c) is the `setup_per_cpu_areas` function. This function setups areas for the `percpu` variables, more about it you can read in the special part about the [Per-CPU variables](http://0xax.gitbooks.io/linux-insides/content/Concepts/per-cpu.html). After `percpu` areas after percpu areas up and running, the next step is the `smp_prepare_boot_cpu` function. This function does some preparations for the [SMP](http://en.wikipedia.org/wiki/Symmetric_multiprocessing):
