From 7c30daac20698cb035255089c896f230982b085e Mon Sep 17 00:00:00 2001 From: Michal Hocko Date: Tue, 22 Mar 2022 14:47:03 -0700 Subject: 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 Acked-by: Rafael Aquini Acked-by: David Hildenbrand Reviewed-by: Mike Rapoport Reviewed-by: Oscar Salvador Cc: Alexey Makhalov Cc: Christoph Lameter Cc: Dennis Zhou Cc: Eric Dumazet Cc: Nico Pache Cc: Tejun Heo Cc: Wei Yang Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- mm/page_alloc.c | 11 ++++++++--- 1 file changed, 8 insertions(+), 3 deletions(-) (limited to 'mm/page_alloc.c') diff --git a/mm/page_alloc.c b/mm/page_alloc.c index d32a635f2c72..584ed4bac85e 100644 --- a/mm/page_alloc.c +++ b/mm/page_alloc.c @@ -7642,9 +7642,14 @@ static void __init free_area_init_node(int nid) pgdat->node_start_pfn = start_pfn; pgdat->per_cpu_nodestats = NULL; - pr_info("Initmem setup node %d [mem %#018Lx-%#018Lx]\n", nid, - (u64)start_pfn << PAGE_SHIFT, - end_pfn ?
