From fc678d67fee1acccf21322318dd833b892a572e4 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Tue, 24 Aug 2010 15:48:50 +0200 Subject: KVM: S390: take a full byte as ext_param indicator Currenty the ext_param field only distinguishes between "config change" and "vring interrupt". We can do a lot more with it though, so let's enable a full byte of possible values and constants to #defines while at it.
