Right, but previously acpi_rsdp was passed automatically and now it
won't be?
Yes, it was. I'm removing them in kexec-tools patches for efi runtime support.
Correct myself about esdata, for old kernels there's no setup_data type for
efi so parse_efi_setup will not be called, thus there will be no effect with
passing new setup_data because nobody use it?
