Recommendation: Monitor — no exploitation signal at the moment.
Cortex-A77 cores (r0p0 and r1p0) are affected by erratum 1508412
where software, under certain circumstances, could deadlock a core
due to the execution of either a load to device or non-cacheable memory,
and either a store exclusive or register read of the Physical
Address Register (PAR_EL1) in close proximity.
