doesn't look like it's compiling with kernel 5.6-rc3 for me.

Are you getting the "implicit declaration of function 'ioremap_nocache'" error or something else?

Mine appears to be something else:

Yeah those went away in -rc3, so their compatibility fixes are probably for -rc1 or -rc2.

The only way I've been able to use Nvidia drivers with 5.6 is by using the packages at "https://github.com/Tk-Glitch/PKGBUILDS". The developer has quite a sophisticated script that allows you to install a variety of driver versions on a variety of kernels. So far I haven't had any problems and I've been using them since 5.6 rc1.
