| 36 | * The value 0x88 means ASI_PRIMARY_LITTLE. | |
| 37 | * The store or load to/from the address space will be done | |
| 38 | * as little-endian. In the original xrog code, the value | |
| 39 | * is defined as the macro ASI_PL. | |

| 41 | * In the original xorg code, "membar #StoreStore|#StoreLoad" | |
| 42 | * is directly implemented as an instruction "0x8143e00a". | |
