 * Structure for representing 32 bit aligned NvU64 (64-bit unsigned integer)
 * structures. This structure must be used because the 32 bit processor and

 *
 * One use case is RM being 64 bit proc whereas PMU being 32 bit proc, this
 * alignment difference will result in corrupted transactions between the RM
 * and PMU.
 *
 * See the @ref NvU64_ALIGN32_PACK and @ref NvU64_ALIGN32_UNPACK macros for
 * packing and unpacking these structures.
 *
 * @note The intention of this structure is to provide a datatype which will
 *       packed/aligned consistently and efficiently across all platforms.
 *       We don't want to use "NV_DECLARE_ALIGNED(NvU64, 8)" because that
 *       leads to memory waste on our 32-bit uprocessors (e.g. FALCONs) where

 * - Casts are not used, as usage in the preprocessor itself (#if) ends poorly.
