- * The ipc64_perm structure for the PPC is identical to kern_ipc_perm
- * as we have always had 32-bit UIDs and GIDs in the kernel.
+ * The ipc64_perm structure for PPC architecture.
+ * Note extra padding because this structure is passed back and forth
+ * between kernel and user space.
+ *
+ * Pad space is left for:
+ * - 1 32-bit value to fill up for 8-byte alignment
+ * - 2 miscellaneous 64-bit values (so that this structure matches
+ *                                  PPC64 ipc64_perm)
