Subject: mmap: remove inline of vm_unmapped_area

Patch series "mm: mmap: add mmap trace point", v3.

Create mmap trace file and add trace point of vm_unmapped_area().


This patch (of 2):

In preparation for next patch remove inline of vm_unmapped_area and move
code to mmap.c.  There is no logical change.

Also remove unmapped_area[_topdown] out of mm.h, there is no code
calling to them.
