+         This option enables the workaround for the 751472 Cortex-A9 (prior
+         to r3p0) erratum. An interrupted ICIALLUIS operation may prevent the
+         completion of a following broadcasted operation if the second
+         operation is received by a CPU before the ICIALLUIS has completed,
+         potentially leading to corrupted entries in the cache or TLB.
