Subject: [kvm-unit-tests PATCH v3 7/9] s390x: smp: Remove unneeded cpu loops
Date: Fri, 17 Jan 2020 05:46:38 -0500	[thread overview]
Message-ID: <20200117104640.1983-8-frankja@linux.ibm.com> (raw)
In-Reply-To: <20200117104640.1983-1-frankja@linux.ibm.com>

Now that we have a loop which is executed after we return from the
main function of a secondary cpu, we can remove the surplus loops.
