ARM errata: Data cache line maintenance operation by MVA may not succeed

configname: CONFIG_ARM_ERRATA_764369

Linux Kernel Configuration
└─>Bus support
└─>ARM errata: Data cache line maintenance operation by MVA may not succeed
In linux kernel since version 3.0.2 (release Date: 2011-08-15)  
This option enables the workaround for erratum 764369
affecting Cortex-A9 MPCore with two or more processors (all
current revisions). Under certain timing circumstances, a data
cache line maintenance operation by MVA targeting an Inner
Shareable memory region may fail to proceed up to either the
Point of Coherency or to the Point of Unification of the
system. This workaround adds a DSB instruction before the
relevant cache maintenance functions and sets a specific bit
in the diagnostic control register of the SCU.
