Log message:
Toggle IBT off during EFI runtime services calls.
While UEFI 2.10 has a way of indicating that runtime services use the
appropriate ENDBR64 instructions, firmware that's out int the wild doesn't
actually use that yet. Once the landscape changes we may want to
reconsider toggling IBT off.
