Subject: [PATCH v3 4/6] mm: don't export memory_add_physaddr_to_nid in arch specific directory
Date:   Thu,  9 Jul 2020 10:06:27 +0800
Message-Id: <20200709020629.91671-5-justin.he@arm.com>
In-Reply-To: <20200709020629.91671-1-justin.he@arm.com>
References: <20200709020629.91671-1-justin.he@arm.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

After a general version of __weak memory_add_physaddr_to_nid implemented
and exported , it is no use exporting twice in arch directory even if
e,g, ia64/x86 have their specific version.

This is to suppress the modpost warning:
WARNING: modpost: vmlinux: 'memory_add_physaddr_to_nid' exported twice.
Previous export was in vmlinux
