In preparation of moving this code to drivers/firmware/efi and reusing it on ARM and arm64, apply any changes that will be required to make this code build for other architectures. This should make it easier to track down problems that this move may cause to its operation on x86. Note that the generic version uses slightly different ways of casting the protocol methods and some other variables to the correct types, since such method calls are not loosely typed on ARM and arm64 as they are on x86.
