No need. If we say, "efi=use_11_map", the 1:1 map will be shoved down
SetVirtualAddressMap. Otherwise the high mappings.

Ok, so it sounds like we want to *always* create both mappings but,
depending on what we want, to shove down SetVirtualAddressMap a
different set. And the 1:1 map will be the optional one which we give
SetVirtualAddressMap only when user wants it, i.e. when booting with
"efi=1:1_map".
Makes sense?
