Subject: [kvm-unit-tests PATCH 4/4] s390x: smp: Dirty fpc before initial reset test
Date: Tue, 14 Jan 2020 10:30:53 -0500	[thread overview]
Message-ID: <20200114153054.77082-5-frankja@linux.ibm.com> (raw)
In-Reply-To: <20200114153054.77082-1-frankja@linux.ibm.com>

Let's dirty the fpc, before we test if the initial reset sets it to 0.
