+ help
+ This option adds a workaround for ARM Neoverse-N1 erratum
+ 1542419.
+
+ Affected Neoverse-N1 cores could execute a stale instruction when
+ modified by another CPU. The workaround depends on a firmware
+ counterpart.
+
+ Workaround the issue by hiding the DIC feature from EL0. This
+ forces user-space to perform cache maintenance.

+ If unsure, say Y.
