mm: make free_area_init_node aware of memory less nodes
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 Link: https://lkml.kernel.org/r/20220127085305.20890-6-mhocko@kernel.org Signed-off-by: Michal Hocko <mhocko@suse.com> Acked-by: Rafael Aquini <raquini@redhat.com> Acked-by: David Hildenbrand <david@redhat.com> Reviewed-by: Mike Rapoport <rppt@linux.ibm.com> Reviewed-by: Oscar Salvador <osalvador@suse.de> Cc: Alexey Makhalov <amakhalov@vmware.com> Cc: Christoph Lameter <cl@linux.com> Cc: Dennis Zhou <dennis@kernel.org> Cc: Eric Dumazet <eric.dumazet@gmail.com> Cc: Nico Pache <npache@redhat.com> Cc: Tejun Heo <tj@kernel.org> Cc: Wei Yang <richard.weiyang@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
