No. The way we do is that we always include the needed Kernel header
with the features, via "make sync-with-kernel". See the README.

Don't hardcode the numbers here. Instead, include the file and use it.
You'll need to patch the main Makefile, in order to copy this header
via "make sync-with-kernel" target.
