From 106c992a5ebef28193cf5958e49ceff5e4aebb04 Mon Sep 17 00:00:00 2001 From: Gerald Schaefer Date: Mon, 29 Apr 2013 15:07:23 -0700 Subject: mm/hugetlb: add more arch-defined huge_pte functions Commit abf09bed3cce ("s390/mm: implement software dirty bits") introduced another difference in the pte layout vs. the pmd layout on s390, thoroughly breaking the s390 support for hugetlbfs. This requires replacing some more pte_xxx functions in mm/hugetlbfs.c with a huge_pte_xxx version. This patch introduces those huge_pte_xxx functions and their generic implementation in asm-generic/hugetlb.h, which will now be included on all architectures supporting hugetlbfs apart from s390. This change will be a no-op for those architectures.
