The above part is necessary for a NUMA kernel.
Could you please merge the attached patch ?
I guess that Christoph Lameter deleted the above part (which is added
by the attached patch again) with the other part of discontigmem lines,
because it depended on CONFIG_ARCH_DISCONTIGMEM_ENABLE.
But the dependency was wrong, and it should depend on CONFIG_NUMA.
The part is necessary for a NUMA kernel even if sparsemem.
Thanks
