Subject: [PATCH 03/12] x86/platform/uv: Adjust references in UV kernel modules
References: <20200907185430.363197758@hpe.com>
MIME-Version: 1.0
Content-Type: text/plain; charset=ISO-8859-15
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

There is a symbol clash from the auto-generated uv_mmrs.h file that
clashes with code in the UV kernel modules (is_uv() is the symbol).
Change those prior to the symbol clash so as to not cause a compile error.
