PL310 errata: Background Clean & Invalidate by Way operation can cause data corruption

configname: CONFIG_PL310_ERRATA_727915

Linux Kernel Configuration
└─>PL310 errata: Background Clean & Invalidate by Way operation can cause data corruption
In linux kernel since version 2.6.39 (release Date: 2011-05-18)  
PL310 implements the Clean & Invalidate by Way L2 cache maintenance
operation (offset 0x7FC). This operation runs in background so that
PL310 can handle normal accesses while it is in progress. Under very
rare circumstances, due to this erratum, write data can be lost when
PL310 treats a cacheable write transaction during a Clean &
Invalidate by Way operation.
