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.
