+ This option adds a workaround for ARM Cortex-A55 erratum #2441007.
+
+ Under very rare circumstances, affected Cortex-A55 CPUs
+ may not handle a race between a break-before-make sequence on one
+ CPU, and another CPU accessing the same page. This could allow a
+ store to a page that has been unmapped.
+
+ Work around this by adding the affected CPUs to the list that needs
+ TLB sequences to be done twice.
+
+ If unsure, say Y.
