[PATCH 00/10] mm: remove CONFIG_HAVE_BOOTMEM_INFO_NODE (Part 2)

[David Hildenbrand (Arm)]

Let's remove the remaining pieces of CONFIG_HAVE_BOOTMEM_INFO_NODE,
performing some smaller cleanups around freeing of reserved vmemmap
pages on the way.

Tested on x86-64 with hugetlb vmemmap optimization in combination with
KMEMLEAK. Heavily cross-compiled.
