ARM errata: possible faulty MMU translations following an ASID switch

└─> ARM errata: possible faulty MMU translations following an ASID switch

This option enables the workaround for the 754322 Cortex-A9 (r2p*,
r3p*) erratum. A speculative memory access may cause a page table walk
which starts prior to an ASID switch but completes afterwards. This
can populate the micro-TLB with a stale entry which may be hit with
the new ASID. This workaround places two dsb instructions in the mm
switching code so that no page table walks can cross the ASID switch.
