Subject: [PATCH v8 4/5] x86/paravirt: Remove const mark from x86_hyper_xen_hvm variable
Date: Tue, 16 Jul 2019 12:26:08 +0800	[thread overview]
Message-ID: <1563251169-30740-1-git-send-email-zhenzhong.duan@oracle.com> (raw)

.. as "nopv" support needs it to be changeable at boot up stage.

Checkpatch reports warning, so move variable declarations from
hypervisor.c to hypervisor.h
