This lets the kernel use any memory not directly used by it or the init ramdisk. Although, now we test whether the kernel fits into the identitymapped area. It can't really grow down there, unless it wants to collide with user-space. Instead, modules and the like (when they are invented), should be put in the upper memory. Or in their own user-space process, yay, microkernel!
