We can't pass the high values via SetVirtualAddressMap and have EFI
runtime in the kexec-ed kernel, as you and I established last week. And
since not all would want EFI runtime in the kexec-ed kernel, I'm leaning
more towards a boot-time option which enables the 1:1 mapping.
Btw, why would you even want the 1:1 mappings if we pass the high values
via SetVirtualAddressMap?
