Patch series "mm: move core MM initialization to mm/mm_init.c", v2.
This set moves most of the core MM initialization to mm/mm_init.c.
This largely includes free_area_init() and its helpers, functions used at
boot time, mm_init() from init/main.c and some of the functions it calls.
Aside from gaining some more space before mm/page_alloc.c hits 10k lines,
this makes mm/page_alloc.c to be mostly about buddy allocator and moves
the init code out of the way, which IMO improves maintainability.
Besides, this allows to move a couple of declarations out of include/linux
and make them private to mm/.
And as an added bonus there a slight decrease in vmlinux size. For
tinyconfig and defconfig on x86 I've got
tinyconfig:
text data bss dec hex filename
853206 289376 1200128 2342710 23bf36 a/vmlinux
