Neoverse-N1: workaround mis-ordering of instruction fetches

└─>Neoverse-N1: workaround mis-ordering of instruction fetches
In linux kernel since version 4.14.326 (release Date: 2023-09-23)
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.
