Subject: [PATCH v2] mm/mmap: fix comment of unmapped_area{_topdown}

The low_limit of unmapped area information is inclusive, and the
hight_limit is not, so make symbol to be [ instead of (.

And replace hight_limit to high_limit.

Fixes: 3499a13168da ("mm/mmap: use maple tree for unmapped_area{_topdown}")
Signed-off-by: Vernon Yang <vernon2gm@...il.com>

Changes since v1:
 - replace hight_limit to high_limit.
