+          Cortex-A9 MPCore micro-architecture, two CPUs working in SMP mode,
+          accessing some data located in the same cache line, may get corrupted
+          data due to bad handling of the address hazard when the line gets
+          replaced from one of the CPUs at the same time as another CPU is
+          accessing it. This workaround sets specific bits in the diagnostic
+          register of the Cortex-A9 which reduces the linefill issuing
+          capabilities of the processor.
