-Subject: [PATCH 3/3] mm: fix new crash in unmapped_area_topdown()
-
-commit f4cb767d76cf7ee72f97dd76f6cfa6c76a5edc89 upstream.
-
-Trinity gets kernel BUG at mm/mmap.c:1963! in about 3 minutes of
-mmap testing. That's the VM_BUG_ON(gap_end < gap_start) at the
-end of unmapped_area_topdown(). Linus points out how MAP_FIXED
-(which does not have to respect our stack guard gap intentions)
-could result in gap_end below gap_start there. Fix that, and
-the similar case in its alternative, unmapped_area().
-
-Fixes: 1be7107fbe18 ("mm: larger stack guard gap, between vmas")
