Unlike with previous Data Fabric versions, with Data Fabric 4.5 non-power-of-2 denormalization, there are bits of the system physical address that can't be fully reconstructed from the normalized address. To determine the proper combination of missing system physical address bits, iterate through each possible combination of these bits, normalize the resulting system physical address, and compare to the original address that is being translated. If the addresses match, then the correct permutation of bits has been found.
