It's not about "integrating changes in mainline kernel", because the
mainline kernel doesn't accept kernel code to support closed-source
OpenGL implementations.

What however could be done is to fix the build of the out-of-tree
kernel module that is provided in gcnano-binaries, so that it works
with an upstream kernel.
