Subject[PATCH 5/6] mm: make free_area_init_node aware of memory less nodes
Date
From: Michal Hocko <mhocko@suse.com>

free_area_init_node is also called from memory less node initialization
path (free_area_init_memoryless_node). It doesn't really make much sense
to display the physical memory range for those nodes:
Initmem setup node XX [mem 0x0000000000000000-0x0000000000000000]

Instead be explicit that the node is memoryless:
Initmem setup node XX as memoryless
