Dan Williams 99490f16f8 mm: ZONE_DEVICE depends on SPARSEMEM_VMEMMAP 
The primary use case for devm_memremap_pages() is to allocate an memmap
array from persistent memory.  That capabilty requires vmem_altmap which
requires SPARSEMEM_VMEMMAP.

Also, without SPARSEMEM_VMEMMAP the addition of ZONE_DEVICE expands
ZONES_WIDTH and triggers the:

"Unfortunate NUMA and NUMA Balancing config, growing page-frame for
last_cpupid."

...warning in mm/memory.c.  SPARSEMEM_VMEMMAP=n && ZONE_DEVICE=y is not
a configuration we should worry about supporting.
