25863de07a powerpc/cpumask: Convert NUMA code to new cpumask API
Convert NUMA code to new cpumask API. We shift the node to cpumask
setup code until after we complete bootmem allocation so we can
dynamically allocate the cpumasks.

17ad6ea621 numa, cpumask: move numa_node_id default implementation to topology.h, fix
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 082edb7bf4 ("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.

b8b572e101 powerpc: Move include files to arch/powerpc/include/asm
from include/asm-powerpc.  This is the result of a

mkdir arch/powerpc/include/asm
git mv include/asm-powerpc/* arch/powerpc/include/asm

Followed by a few documentation/comment fixups and a couple of places
where <asm-powepc/...> was being used explicitly.  Of the latter only
one was outside the arch code and it is a driver only built for powerpc.
