   Yes, you are right.
   Unused bits, depending on the page size. For simplicity and generality, we can choose 12.
   How about the following modifications.
   
   #elif defined(__aarch64__)
   #define FREELIST_POINTER(_x) ((void *)((((intptr_t)(_x).data) & 0x000FFFFFFFFFFFFFULL)))
   #define FREELIST_VERSION(_x) (((intptr_t)(_x).data) >> 52)
   #define SET_FREELIST_POINTER_VERSION(_x, _p, _v) (_x).data = (((intptr_t)(_p)) | (((_v)&0xFFFULL) << 52))
