IAMROOT16 Linux kernel v5.1 study log tree

We planed studying on week [001 ~ 067] Arm64 Linux kernel boot flow. so, we reviewed source code line by line, from arch/arm64/kernel/head.S to init/main.c::start_kernel() → mm/page_alloc.c::page_alloc_init().
After week [067 ~ ], we decided to learn each subsystem unit of the Linux kernel, starting target was the buddy system.
