Re: [PATCH] arm64: add ARM64-specific support for flatmem

Will modify the patch to remove ARM64. Every other architecture kept def_bool y for it so I followed the same for ARM64 too.

Thanks,

We don't need ARM64 here. I'm also not sure about the def_bool y, this seems
like a pretty niche thing to enable.
