Subject: [PATCH] KVM: remove unused guest_enter/exit
Date:   Fri, 10 Jan 2020 11:13:56 +0800
Message-Id: <1578626036-118506-1-git-send-email-alex.shi@linux.alibaba.com>
To:     unlisted-recipients:; (no To-header on input)
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

After commit 6edaa5307f3f ("KVM: remove kvm_guest_enter/exit wrappers")
no one uses guest_enter/exit anymore.

So better to remove them to simplify code and reduced a bit of object
size.
