+	  This option adds a workaround for Arm Cortex-A76 erratum 1463225.
+
+	  On the affected Cortex-A76 cores (r0p0 to r3p1), software stepping
+	  of a system call instruction (SVC) can prevent recognition of
+	  subsequent interrupts when software stepping is disabled in the
+	  exception handler of the system call and either kernel debugging
+	  is enabled or VHE is in use.
+
+	  Work around the erratum by triggering a dummy step exception
+	  when handling a system call from a task that is being stepped
+	  in a VHE configuration of the kernel.
+
+	  If unsure, say Y.
