Subject: [PATCH v2 1/7] x86/xen: Mark xen_hvm_need_lapic() and xen_hvm_need_lapic() as __init
Date: Mon, 24 Jun 2019 20:02:53 +0800 [thread overview]
Message-ID: <1561377779-28036-2-git-send-email-zhenzhong.duan@oracle.com> (raw)
In-Reply-To: <1561377779-28036-1-git-send-email-zhenzhong.duan@oracle.com>
.. as they are only called at early bootup stage. In fact, other
functions in x86_hyper_xen_hvm.init.* are all marked as __init.
Unexport xen_hvm_need_lapic as it's never used outside.
