Commit e2cda322648122dc400c85ada80eaddbc612ef6a 'thp: add pmd mangling
generic functions' replaced some macros in <asm-generic/pgtable.h>
with inline functions. If the functions are to be defined (not all
architectures need them) then struct vm_area_struct must be defined
first. So include <linux/mm_types.h>.
Fixes a build failure seen in Debian:
