PS23, Line 7: 	default y if ARCH_ARM64
> Sorry, I don't really understand... I'm pretty sure that should work. […]

IIUC the issue is that the option doesn't have a default, it's by default hidden and this would be adding a default which doesn't make sense if hidden behind another guard:

```
config ARCH_SUPPORTS_CLANG
    bool
    help
      Opt-in flag for architectures that generally work well with CLANG.
      By default the option would be hidden.
```

You could probably add the default as no and then follow the suggestion above?
