Will Deacon 475d92fc6e ARM: 6416/1: errata: faulty hazard checking in the Store Buffer may lead to data corruption 
On the r2p0, r2p1 and r2p2 versions of the Cortex-A9, data corruption
can occur under very rare conditions due to a store buffer optimisation.

This workaround sets a bit in the diagnostic register of the Cortex-A9,
disabling the optimisation and preventing the problem from occurring.
