Remarks
A hardware memory fence ensures that all memory reads and writes are made visible to all processors prior to any subsequent memory reads and writes. The __mf intrinsic does not ensure that these memory reads and writes have been accepted by the platform. If that is a requirement, use __mfa.
This routine is only available as an intrinsic.
