Do not try to compile the modules for newer kernels as it is not possible anymore. Instead you need to compile THE KERNEL itself with the modules options enabled in the config file as the modules had been migrated to the newer kernels but some code had been removed that prevents you from building/using the modules standalone for security reasons.

You can look at my tutorial/notice i wrote down to address the issue for myself or use my precompiled kernels (with the android config options pre-enabled) if you are using a ubuntu distribution.

Its the way it should not be done anymore. It has been removed as a external function for good. It is included in the kernel itself.
