[PATCH] numa, cpumask: move numa_node_id default implementation to topology.h, fix

[Stephen Rothwell]

Impact: build fix for powerpc and sparc

Today's linux-next build (powerpc allyesconfig) failed like this:

> In file included from include/linux/mmzone.h:776,
>                  from include/linux/gfp.h:5,
>                  from include/linux/kmod.h:23,
>                  from include/linux/module.h:14,
>                  from init/version.c:11:
> arch/powerpc/include/asm/mmzone.h:32: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'numa_cpumask_lookup_table'

Caused by commit 082edb7bf443eb8eda15b482d16ad9dd8137ad24 ("numa,
cpumask: move numa_node_id default implementation to topology.h") from
the cpus4096 tree which removed the include of linux/topology.h from
linux/mmzone.h.

Same for sparc64 defconfig.
