+    Linux: Support __IPC_64 in sysvctl *ctl command arguments (bug 29771)
+    
+    Old applications pass __IPC_64 as part of the command argument because
+    old glibc did not check for unknown commands, and passed through the
+    arguments directly to the kernel, without adding __IPC_64.
+    Applications need to continue doing that for old glibc compatibility,
+    so this commit enables this approach in current glibc.
+    
+    For msgctl and shmctl, if no translation is required, make
+    direct system calls, as we did before the time64 changes.  If
+    translation is required, mask __IPC_64 from the command argument.
+    
+    For semctl, the union-in-vararg argument handling means that
+    translation is needed on all architectures.
