In linux kernel since version 2.6.36 (release Date: 2010-10-20)
This option enables the workaround for the 743622 Cortex-A9
(r2p*) erratum. Under very rare conditions, a faulty
optimisation in the Cortex-A9 Store Buffer may lead to data
corruption. This workaround sets a specific bit in the diagnostic
register of the Cortex-A9 which disables the Store Buffer
optimisation, preventing the defect from occurring. This has no
visible impact on the overall performance or power consumption of the
processor. Note that setting specific bits in the diagnostics register
may not be available in non-secure mode and thus is not available on a
multiplatform kernel. This should be applied by the bootloader instead.
