Looking at the "Initialization of the system calls table" section, it's quite misleading since the syscall table isn't used in newer kernel versions and the arch/x86/entry/syscall_64.c file is linked which looks different now, see https://github.com/torvalds/linux/blob/master/arch/x86/entry/syscall_64.c#L19.
