Subject: [kvm-unit-tests PATCH v4 9/9] s390x: smp: Dirty fpc before initial reset test
Date: Tue, 21 Jan 2020 08:42:54 -0500 [thread overview]
Message-ID: <20200121134254.4570-10-frankja@linux.ibm.com> (raw)
In-Reply-To: <20200121134254.4570-1-frankja@linux.ibm.com>
Let's dirty the fpc, before we test if the initial reset sets it to 0.
