Patch series "mm: move core MM initialization to mm/mm_init.c".

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
 853198	 289344	1200128	2342670	 23bf0e	b/vmlinux

defconfig:
    text   	   data	    bss	    dec	    	    hex	filename
26152959	9730634	2170884	38054477	244aa4d	a/vmlinux
26152945	9730602	2170884	38054431	244aa1f	b/vmlinux


This patch (of 15):

Comment about fixrange_init() says that its called from pgtable_init()
while the actual caller is pagetabe_init().

Update comment to match the code.
