These modules just need the configured kernel for them to build with. It is not specific to particular kernel version. Also, every time the Kernel version moves, this whole set needs to be moved too. Instead have it in the BSP and we do not have to run around moving around with the different kernels. Instead it is nice to have one copy in common.
