+Subject: MIPS: Only include mmzone.h when CONFIG_NEED_MULTIPLE_NODES=y
+
+From: Paul Burton <paul.burton@mips.com>
+
+commit 66a4059ba72c23ae74a7c702894ff76c4b7eac1f upstream.
+
+MIPS' asm/mmzone.h includes the machine/platform mmzone.h
+unconditionally, but since commit bb53fdf395ee ("MIPS: c-r4k: Add
+r4k_blast_scache_node for Loongson-3") is included by asm/rk4cache.h for
+all r4k-style configs regardless of CONFIG_NEED_MULTIPLE_NODES.
+
+This is problematic when CONFIG_NEED_MULTIPLE_NODES=n because both the
+loongson3 & ip27 mmzone.h headers unconditionally define the NODE_DATA
+preprocessor macro which is aready defined by linux/mmzone.h, resulting
+in the following build error:
+
+  In file included from ./arch/mips/include/asm/mmzone.h:10,
+                   from ./arch/mips/include/asm/r4kcache.h:23,
+                   from arch/mips/mm/c-r4k.c:33:
+  ./arch/mips/include/asm/mach-loongson64/mmzone.h:48: error: "NODE_DATA" redefined [-Werror]
+   #define NODE_DATA(n)  (&__node_data[(n)]->pglist)
+
+  In file included from ./include/linux/topology.h:32,
+                   from ./include/linux/irq.h:19,
+                   from ./include/asm-generic/hardirq.h:13,
+                   from ./arch/mips/include/asm/hardirq.h:16,
+                   from ./include/linux/hardirq.h:9,
+                   from arch/mips/mm/c-r4k.c:11:
+  ./include/linux/mmzone.h:907: note: this is the location of the previous definition
+   #define NODE_DATA(nid)  (&contig_page_data)
+
+Resolve this by only including the machine mmzone.h when
+CONFIG_NEED_MULTIPLE_NODES=y, which also removes the need for the empty
+mach-generic version of the header which we delete.
