[PATCH 1/3] mm/mm_init.c: remove comments in zone_spanned_pages_in_node() and zone_absent_pages_in_node()

From: Haifeng Xu
Date: Thu May 25 2023 - 00:02:53 EST


Since commit 03e85f9d5f1f ("mm/page_alloc: Introduce free_area_init_core_hotplug"),
free_area_init_node() doesn't get called in hotplug path anymore, so
remove the comments related to it.
