Yang Shi 49ccf2c3ca arm64: mte: set VM_MTE_ALLOWED for hugetlbfs at correct place The commit `5de195060b` ("mm: resolve faulty mmap_region() error path behaviour") moved vm flags validation before fop->mmap for file mappings. But when commit `25c17c4b55` ("hugetlb: arm64: add mte support") was rebased on top of it, the hugetlbfs part was missed. Mmapping hugetlbfs file may not have MAP_HUGETLB set.

Yang Shi 49ccf2c3ca arm64: mte: set VM_MTE_ALLOWED for hugetlbfs at correct place

The commit 5de195060b ("mm: resolve faulty mmap_region() error path
behaviour") moved vm flags validation before fop->mmap for file
mappings.  But when commit 25c17c4b55 ("hugetlb: arm64: add mte support")
was rebased on top of it, the hugetlbfs part was missed.  Mmapping
hugetlbfs file may not have MAP_HUGETLB set.
