    kexec kernel will need exactly same mapping for EFI runtime memory
    ranges. Thus here export the runtime ranges mapping to sysfs,
    kexec-tools will assemble them and pass to 2nd kernel via setup_data.

    Introducing a new directory /sys/firmware/efi/runtime-map just like
    /sys/firmware/memmap. Containing below attribute in each file of that
    directory:

    attribute num_pages phys_addr type virt_addr
