I have no idea what AS_AVX2 means, sorry. So what would it mean if someone has a .config with CONFIG_AS_AVX2=foo
Ie, what would happen if someone using a toolchain for which that would not be possible tries to build a kernel with that symbol set? That person's .config would end up containing # CONFIG_AS_AVX2 is not set
or similar, right?
