I suspect maybe it uses hugetlbs?
There were a couple of commits to fix VM_ACCOUNT for hugepage areas recently. See
- 5a6fe125950676015f5108fb71b2a67441755003: "Do not account for the address space used by hugetlbfs using VM_ACCOUNT"
- 17c9d12e126cb0de8d535dc1908c4819d712bc68: "Do not account for hugetlbfs quota at mmap() time if mapping [SHM|MAP]_NORESERVE"
because hugetlb mappings have their own magical VM accounting.
So can you check if current -git fixes it?
