In addition to the same issue as efi.memmap.phys_map, efi_phys has
the __initdata attribute so it will be released/freed which will cause

Sounds to me like we should drop the __initdata attr and prepare them
much earlier for use by the SME code.

Probably something we can look at for a follow-on patch.

Thanks,
