Installation or Setup
Linux kernel source code can be found in https://www.kernel.org/
Download extract and enter to the kernel directory
Type these commands step by steps in your terminal.(Choose the appropriate version you needed instead of linux-4.7.tar.gz )
wget http://www.kernel.org/pub/linux/kernel/v4.7/linux-4.7.tar.gz
tar zxvf linux-4.7.tar.gz
cd linux-4.7
make menuconfig will select the features required for the kernel.
Old kernel configurations can be copied by using old .config file and executing make oldconfig . Also we can use make xconfig as a graphical version of the configuration tool.
Build the dependencies, compile the kernel and modules.
make dep
make bzImage
make modules
make modules_install
Alternatively if you want to reconfigure the old kernel and re compile it, execute the below commands:
make mrproper
make menuconfig
make dep
make clean
make bzImage
make modules
make modules_install
Then copy the kernel, system.map file to /boot/vmlinuz-4.7
create a .conf file with the below content
image = /boot/vmlinuz-4.7
label = "Linux 4.7"
Then execute lilo -v to modify the boot sector and reboot.
