You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: mod.rs
    path of file: ./repos/rCore/kernel/src/arch/x86_64
    
    the code of the file until where you have to start completion: use core::sync::atomic::*;
use log::*;
use rboot::BootInfo;

pub mod acpi;
pub mod board;
pub mod consts;
pub mod cpu;

    
fn other_start() -> ! {
    // init trap handling
    unsafe {
        trapframe::init();
    }
    // init local apic
    cpu::init();
    // call the first main function in kernel.
    crate::kmain();
}
