Subject: [PATCH] x86/Hyper-V: Fix reference of pv_ops with CONFIG_PARAVIRT=N
Date:   Wed, 28 Aug 2019 16:07:47 +0800
Message-Id: <20190828080747.204419-1-Tianyu.Lan@microsoft.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Tianyu Lan <Tianyu.Lan@microsoft.com>

hv_setup_sched_clock() references pv_ops and this should
be under CONFIG_PARAVIRT=Y. Fix it.
