1184 This option enables the workaround for the 751472 Cortex-A9 (prior
1185 to r3p0) erratum. An interrupted ICIALLUIS operation may prevent the
1186 completion of a following broadcasted operation if the second
1187 operation is received by a CPU before the ICIALLUIS has completed,
1188 potentially leading to corrupted entries in the cache or TLB.
