I see more CONFIG options with a weird help. config 64BIT def_bool y if X86_EFI select ARCH_DMA_ADDR_T_64BIT help Say yes to build a 64-bit binary - formerly known as x86_64 Say no to build a 32-bit binary - formerly known as i386. You cannot say yes or no here since Kconfig does not show a prompt in the first place.
