The OpenBSD EFI bootloader calls ExitBootServices() before handing control to the kernel. The OpenBSD/arm64 kernel then calls SetVirtualAddressmap(). This works, but probably because it happens very early when the kernel is only using memory inside a 32M block that has been allocated by the bootloader. So yes, I think that functionality needs to marked as __efi_runtime.
