It seems you don't listen me. I said multiple times - MIPS 
implementation of SYNC_RMB/SYNC_WMB/SYNC_MB/SYNC_ACQUIRE/SYNC_RELEASE 
instructions matches the description of 
smp_rmb/smp_wmb/smp_mb/sync_acquire/sync_release from 
Documentation/memory-barriers.txt file.
What else do you want from me - RTL or microArch design for that?
