Subject: [PATCH] mm/page_alloc: make alloc_node_mem_map() __init rather than
 __ref

References: bsc#1190208 (MM functional and performance backports)
Patch-mainline: v5.15-rc1
Git-commit: 3b446da6be7a722d769e23f68dbaf4ebb2eda542

alloc_node_mem_map() is never only called from free_area_init_node() that
is an __init function.

Make the actual alloc_node_mem_map() also __init and its stub version
static inline.
