From 4027149abde8d57da4c4c4f498b310c85a297bba Mon Sep 17 00:00:00 2001 From: Baoquan He Date: Wed, 1 Apr 2020 21:09:34 -0700 Subject: mm/sparse.c: allocate memmap preferring the given node When allocating memmap for hot added memory with the classic sparse, the specified 'nid' is ignored in populate_section_memmap(). While in allocating memmap for the classic sparse during boot, the node given by 'nid' is preferred. And VMEMMAP prefers the node of 'nid' in both boot stage and memory hot adding. So seems no reason to not respect the node of 'nid' for the classic sparse when hot adding memory. Use kvmalloc_node instead to use the passed in 'nid'.
