When ARCH_SUPPORTS_DEBUG_PAGEALLOC is not selected, the user can
still select CONFIG_DEBUG_PAGEALLOC in which case __kernel_map_pages()
is provided by mm/page_poison.c
So only define __kernel_map_pages() when both
CONFIG_ARCH_SUPPORTS_DEBUG_PAGEALLOC and CONFIG_DEBUG_PAGEALLOC
are defined.

and KFENCE")
