mm/hugetlb: do not dissolve gigantic pages without runtime support
In the Linux kernel, the following vulnerability has been resolved: mm/hugetlb: do not dissolve gigantic pages without runtime support dissolve_free_hugetlb_folio() doesn't check hstate_is_gigantic_no_runtime(h) though remove_hugetlb_folio()/ update_and_free_hugetlb_folio() silently bail for such folios, so it frees a still-listed folio and, on vmemmap restore failure, the add_hugetlb_folio() rollback corrupts the free list.
