Patch [use patch -R] to make proprietary linux nvidia driver 370.28 compatible with v4.9-rt1 kernel, change several of the module_license entries to make it "future-proof" for newer kernels [for users only ! non-distribution !]

actually the inverse of the patch is correct 😆

just noticed that now after creating it ^^

so apply it via

patch -p1 -R < ...

Before compiling it with rt-kernel

the following command

export IGNORE_PREEMPT_RT_PRESENCE=1

needs to be executed

Hello! Would you kindly explain how to apply the patch? I'm not sure what goes at "..." for the patch line.
Any explicit command lines would be greatly appreciated!
Thank you!
