So I had to end up instrumenting the EFI stub to see where the error came
from. At the start of the stub, there is no GHES.2 error. The error first
shows up after the stub's call to ExitBootServices returns. So it looks
like the firmware itself is causing the error. There's still a chance that
the stub is doing something wrong with the memory map passed to the
firmware, so I'll try to eliminate that as well.
