[Xen-devel] [PATCH v5 1/4] x86/xen: Mark xen_hvm_need_lapic() and xen_x2apic_para_available() as __init

[Zhenzhong Duan <zhenzhong.duan@xxxxxxxxxx>]

.. 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.
