It is the end of the fifth part about linux kernel initialization process. In this part we continued to dive in the `setup_arch` function which makes initialization of architecture-specific stuff. It was long part, but we have not finished with it. As i already wrote, the `setup_arch` is big function, and I am really not sure that we will cover all of it even in the next part. There were some new interesting concepts in this part like `Fix-mapped` addresses, ioremap and etc... Don't worry if they are unclear for you. There is a special part about these concepts - [Linux kernel memory management Part 2.](https://github.com/0xAX/linux-insides/blob/master/MM/linux-mm-2.md). In the next part we will continue with the initialization of the architecture-specific stuff and will see parsing of the early kernel parameters, early dump of the pci devices, direct Media Interface scanning and many many more.
