* wget https://www.kernel.org/pub/linux/kernel/v4.x/testing/linux-4.0-rc2.tar.xz
  * 解压内核
  * 根据README中步骤操作即可
<code>
     mkdir -p /home/name/build/kernel
     cd /usr/src/linux-3.X
     make mrproper  #编译前清空一下
     make O=/home/name/build/kernel menuconfig
     make O=/home/name/build/kernel
     sudo make O=/home/name/build/kernel modules_install install
     
     或者
     make INSTALL_MOD_STRIP=1 -j20
     make INSTALL_MOD_STRIP=1 -j20 modules
     make INSTALL_MOD_STRIP=1 -j20 modules_install
     make INSTALL_MOD_STRIP=1 -j20 install
</code>

我用的是ubuntu14.04编译安装过后重启就可以直接选择内核了。Centos还没有测试

centos 6.5 编译3.10.80内核
  * could not load /lib/modules/3.10.80/modules.dep
    * 解决办法：参考http://blog.path8.net/archives/6002.html
    * <code>dracut -f -v --hostonly -k '/lib/modules/3.10.80'  /boot/initramfs-3.10.80.img 3.10.80</code>
