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.
