+	  ARM v8.2 adds a feature to add implicit error synchronization
+	  barriers whenever the CPU enters or exits a particular exception
+	  level.
+
+	  On CPUs with this feature and the 'RAS Extensions' feature, we can
+	  use this to contain detected (but not yet reported) errors to the
+	  relevant exception level.
+
+	  The feature is detected at runtime, selecting this option will
+	  enable these implicit barriers if the CPU supports the feature.
