“Welcome to the Linux Kernel Archives. This is the primary site for the Linux kernel source, but it has much more than just Linux kernels.” To begin, choose your protocol and go to the site to download the kernel of your choice to your computer. The http://www.kernel.org/ website is not the only place to retrieve patches. Many other vendors and individuals have developed patches to improve aspects of the kernel's performance, support new hardware, or introduce features that are too esoteric or experimental to make it to the stock kernel. For the most part these third-party kernels are stable but do use your judgment when downloading and applying them. Once you have retrieved the kernel sources and patches, you will need to extract them and apply the patches.
