Functions
void	kmain (struct boot *boot)
	Starts the kernel's generic part, once the architecture has set up the CPU, memory and the platform.

Detailed Description

The kernel's generic entry point, kmain().

The architecture's boot code sets up the CPU and memory, then calls kmain(), which sets up the devices and filesystems, mounts the root filesystem, and starts the first process, /init. See docs/kernel/booting.md.
