I am not so familiar with the exact steps, but you could find pre patched kernels somewhere. What you have downloaded is the platform code that runs in the user mode and comprises of the Android platform code and applications. Just an analogy to make things clear, even though Linux kernel is just 50MB the popular distributions extent to over gigabytes in size. Thats again because they bundle several applications along with it which increases the package size. > > > and , finally(phew!)
