Yeah, I'm not advocating using casts, I was just saying "Oh, x86-64 avoids requiring the caller of efi_call_phys* to perform the cast by doing it in the definition of efi_call*. That's why this is only affecting 32-bit."
Cleaning this up would be nice. I think at this point, I'll apply Borislav's patch, and fix all this casting after v3.9 is released, since instead of just changing query_variable_info, we might as well change everything in efi_runtime_service_t so that it's consistent.
