+	  Affected parts may corrupt the AES state if an interrupt is
+	  taken between a pair of AES instructions. These instructions
+	  are only present if the cryptography extensions are present.
+	  All software should have a fallback implementation for CPUs
+	  that don't implement the cryptography extensions.
