Some functions are passing addresses instead of pointers to the efi_add_memory_map() function. This confusion is understandable since the function arguments indicate an address.
Make a note of the 8 places where there are problems, which would break usage in sandbox tests.
Future work will resolve these problems.

Changes in v2: - Add a new patch with comments where incorrect addresses are used
