+ This option enables the workaround for the 720789 Cortex-A9 (prior to
+ r2p0) erratum. A faulty ASID can be sent to the other CPUs for the
+ broadcasted CP15 TLB maintenance operations TLBIASIDIS and TLBIMVAIS.
+ As a consequence of this erratum, some TLB entries which should be
+ invalidated are not, resulting in an incoherency in the system page
+ tables. The workaround changes the TLB flushing routines to invalidate
