No, I think x86's implementation is incorrect. efi_get_memory_map()
should allocate some slack (i.e., the 8 entries you mentioned), and if
the first call to ExitBootServices() fails, we should reuse the memory
map buffer, and call GetMemoryMap() directly to repopulate it. Then,
we call ExitBootServices() once more, or give up if either call fails.
This way, we are 100% compliant with the wording of the spec, and err
on the side of caution.
Ok. Let me take some time to think upon this approach and develop a
working prototype.
Thanks for providing your guidance in a very expedient manner.
