Subject: [PATCH 7/8] mm: move lib/ioremap.c to mm/

From: Mike Rapoport <rppt@...ux.ibm.com>

The functionality in lib/ioremap.c deals with pagetables, vmalloc and
caches, so it naturally belongs to mm/
Moving it there will also allow declaring p?d_alloc_track functions in an
header file inside mm/ rather than having those declarations in
include/linux/mm.h
