* The shmid64_ds structure for the MIPS architecture. |

* Note extra padding because this structure is passed back and forth |
|
* between kernel and user space. |
|
* |
|
* As MIPS was lacking proper padding after shm_?time, we use 48 bits |
|
* of the padding at the end to store a few additional bits of the time. |
|
* libc implementations need to take care to convert this into a proper |
|
* data structure when moving to 64-bit time_t. |
