Not sure if the diff might be a bit misleading here, the signature of
thp_get_unmapped_area() didn't actually change.
If thp_get_unmapped_area() is made into a static inline, then
thp_get_unmapped_area_vmflags() would need to be exported instead so it
could be used in some modules. Unlike get_unmapped_area()
thp_get_unmapped_area is actually is used that way.
Better to export the more limited version?
