+	  This option adds the workaround for ARM Cortex-A715 erratum 2645198.
+
+	  If a Cortex-A715 cpu sees a page mapping permissions change from executable
+	  to non-executable, it may corrupt the ESR_ELx and FAR_ELx registers on the
+	  next instruction abort caused by permission fault.
+
+	  Only user-space does executable to non-executable permission transition via
+	  mprotect() system call. Workaround the problem by doing a break-before-make
+	  TLB invalidation, for all changes to executable user space mappings.
+
+	  If unsure, say Y.
