HOW TO PATCH
1. Extract NVidia Driver (64 bit)
./NVIDIA-Linux-x86_64-390.138.run --extract-only
2. Go to the extracted directory
cd NVIDIA-Linux-x86_64-390.138
3. Patch it
patch -p1 < /path/to/kernel-4.16.patch
patch -p1 < /path/to/kernel-5.8.patch
patch -p1 < /path/to/kernel-5.8-license-bypass.patch
patch -p1 < /path/to/kernel-5.9.patch
patch -p1 < /path/to/kernel-5.10.patch
4. Run the nvidia-installer
./nvidia-installer --no-unified-memory
5. Have fun :)
