Subject: [PATCH] MIPS: SGI-IP27: replace MAX_COMPACT_NODE with MAX_NUMNODES
Date:   Wed, 30 Oct 2019 11:51:44 +0100
Message-Id: <20191030105144.10686-1-tbogendoerfer@suse.de>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

MAX_COMPACT_NODE is a leftover from the compact node implementation,
which is removed now.  Use MAX_NUMNODES instead.
