The major distros often have their own kernels. They stay on a stable kernel but backport patches, making something wholly unique. To identify a unique kernel, Red Hat and SuSE put identifiers in their kernel. Until recently, Ubuntu did not, even after multiple requests.
It takes some effort to compile on these hybrid kernels, and that's what's in our kcompat.[ch] files. Without the kernel identifiers in Ubuntu (i.e. pre-14.04.1), it's difficult to target the workarounds. Also, we have a finite number of people working on the drivers and we only support a subset of all the variants out there. Even harder than writing the code is validating the code, especially with all the different hardware there is. Stable kernels, Red Hat, and SuSE are officially supported at this time.

I was under the impression that the kernel does not differ? I have tried to remove the UTS_UBUNTU_RELEASE_ABI directive and the error (UTS_UBUNTU_RELEASE_ABI is too large) went away. The error about the implicit declaration remained which in the end caused the build to about remained. I searched in the Makefile but did not found where the gcc option '-Werror=implicit-function-declaration‘ is defined.
