ARM errata: Interrupted ICIALLUIS may prevent completion of broadcasted operation

└─>ARM errata: Interrupted ICIALLUIS may prevent completion of broadcasted operation
In linux kernel since version 2.6.38 (release Date: 2011-03-14)  
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.
