This will need to do riscv and s390 too. Though, really, I think the right path is to work toward removing huge_ptep_get() from the arch code.. riscv and arm are doing the same thing - propogating dirty/young bits from the contig PTEs to the results. The core code can do this, maybe with a ARCH #define opt in. s390.. Ouchy - is this because hugetlb wants to pretend that every level is encoded as a PTE so it takes the PGD and recodes the flags to the PTE layout?? Jason
