Subject: [kvm-unit-tests PATCH v2 7/7] s390x: smp: Dirty fpc before initial reset test
Date: Thu, 16 Jan 2020 07:05:13 -0500 [thread overview]
Message-ID: <20200116120513.2244-8-frankja@linux.ibm.com> (raw)
In-Reply-To: <20200116120513.2244-1-frankja@linux.ibm.com>
Let's dirty the fpc, before we test if the initial reset sets it to 0.
