[PATCH] arm64/mm: Make vmemmap_free() available only with CONFIG_MEMORY_HOTPLUG
From: Anshuman Khandual <hidden>
Date: 2021-05-24 07:40:01
vmemmap_free() callsites (mm/sparse.c) and declaration (include/linux/mm.h) are protected with CONFIG_MEMORY_HOTPLUG. This function is not required if CONFIG_MEMORY_HOTPLUG is not enabled. Hence move the config wrapper outside the function definition.
