    Security: disable nontemporals. · a904b569

    The operations were available on ARM64 and x86-32 but were unused.
    
    It has been conjectured that nontemporals can be used for rowhammer-like bitflips more easily than regular load/store operations. It is therefore desirable to avoid generating these instructions in the future.
