Smirk. It's not truncated, it's condensed ;-)

It's a defconfig, as generated by make savedefconfig.

https://stackoverflow.com/questions/27899104/how-to-create-a-defconfig-file-from-a-config

Save it to e.g. arch/arm64/configs/marc_defconfig and then you can
just run 'make marc_defconfig' to generate the .config

Regards.
