+Subject: s390x: Return specification exception for unimplemented diag 308
+ subcodes
+
+The architecture specifies specification exceptions for all
+unavailable subcodes.
+
+The presence of subcodes is indicated by checking some query subcode.
+For example 6 will indicate that 3-6 are available. So future systems
+might call new subcodes to check for new features. This should not
+trigger a hw error, instead we return the architectured specification
+exception.
