- Now contains a 'page_size' field, used throughout the functions - Removed NvPageSize - Removed nvAddressSpaceReserveAlign/AtFixedAddr/Full - Added nvAddressSpaceAlloc/AllocFixed/Free (replacing above functions) - Removed nvAddressSpaceMapBuffer/UnmapBuffer - Added nvAddressSpaceMap/MapFixed/Modify/Unmap (replacing above functions) - Adapted NvBuffer/NvGpu to use the new functions
