    Btw, I was about to ask: how do you pass boot_params to the kexec
    kernel?

    Because I'm looking into hpa's idea to pass an efi_mapping array of
    regions with setup_data but how does this get passed to the kexec'ed
    kernel? I see in your patches you have boot_params.saved_*** for the
    needed info but you're not writing to them anywhere. Is that why you've
    added them to the systab_show function so that userspace can parse it
    and build the boot_params thing?

    Thanks.
