Subject: [kvm-unit-tests PATCH v3 2/9] s390x: Define the PSW bits
Date: Fri, 6 Dec 2019 17:26:21 +0100 [thread overview]
Message-ID: <1575649588-6127-3-git-send-email-pmorel@linux.ibm.com> (raw)
In-Reply-To: <1575649588-6127-1-git-send-email-pmorel@linux.ibm.com>
Let's define the PSW bits explicitly, it will clarify their
usage.
