Subject: [kvm-unit-tests PATCH v8 02/12] s390x: Move control register bit definitions and add AFP to them
Date: Mon, 8 Jun 2020 10:12:51 +0200 [thread overview]
Message-ID: <1591603981-16879-3-git-send-email-pmorel@linux.ibm.com> (raw)
In-Reply-To: <1591603981-16879-1-git-send-email-pmorel@linux.ibm.com>
While adding the definition for the AFP-Register control bit, move all
existing definitions for CR0 out of the C zone to the assmbler zone to
keep the definitions concerning CR0 together.
