Message-ID: <1452010645-25380-1-git-send-email-mst@redhat.com> Date: Tue, 5 Jan 2016 18:17:53 +0200 From: "Michael S. Tsirkin" <mst@...hat.com> To: linux-kernel@...r.kernel.org Cc: Martin Schwidefsky <schwidefsky@...ibm.com>, Heiko Carstens <heiko.carstens@...ibm.com>, Christian Borntraeger <borntraeger@...ibm.com>, linux-s390@...r.kernel.org Subject: [PATCH] s390: drop smp_mb in vdso_init The initial s390 vdso code is heavily influenced by the powerpc version which does have a smp_wmb in vdso_init right before the vdso_ready=1 assignment. s390 has no need for that.
