I downloaded N9's Linux kernel source code, but how to compile it if I make some change of it? After that, how to flash the new kernel into N9?

I know the process on N900, but as for N9, no idea.
And in the below page, it mentions OneClickFlasher, but only for N950, right? Can it also be used for N9?
