I finally finished my thought. The sysfs code should be automatically
enabled only if CONFIG_KEXEC is enabled, and not on my default because
it is a debug interface. While it's true that the code may be useful for
debugging the memory mappings of EFI systems, it doesn't make sense to
always turn it on just for CONFIG_X86 and CONFIG_EFI.
