Ok, but but, why doesn't the normal code path in efi_enter_virtual_mode
work anymore? I mean, why do you need another function instead of doing
what you did previously:

	if (!kexec)
		phys_efi_set_virtual_address_map(...)

The path up to here does the mapping already anyway so you only need to
do the mapping in the kexec kernel and skip set set_virtual_map thing.

Thanks.
