We fix this by making EDAT1 a hard requirement for hugepages and therefore removing and simplifying code. As s390, with the sw-emulated hugepages, was the only user of arch_prepare/release_hugepage I also removed theses calls from common and other architecture code. Thanks, Dominik Dominik Dingel (5): s390/mm: make hugepages_supported a boot time decision mm/hugetlb: remove unused arch hook prepare/release_hugepage mm/hugetlb: remove arch_prepare/release_hugepage from arch headers s390/hugetlb: remove dead code for sw emulated huge pages s390/mm: forward check for huge pmds to pmd_large() arch/arm/include/asm/hugetlb.h | 9 ------ arch/arm64/include/asm/hugetlb.h | 9 ------ arch/ia64/include/asm/hugetlb.h | 9 ------ arch/metag/include/asm/hugetlb.h | 9 ------ arch/mips/include/asm/hugetlb.h | 9 ------ arch/powerpc/include/asm/hugetlb.h | 9 ------ arch/s390/include/asm/hugetlb.h | 3 -- arch/s390/include/asm/page.h | 8 ++--- arch/s390/kernel/setup.c | 2 ++ arch/s390/mm/hugetlbpage.c | 65 +++----------------------------------- arch/s390/mm/pgtable.c | 2 ++ arch/sh/include/asm/hugetlb.h | 9 ------ arch/sparc/include/asm/hugetlb.h | 9 ------ arch/tile/include/asm/hugetlb.h | 9 ------ arch/x86/include/asm/hugetlb.h | 9 ------ mm/hugetlb.c | 10 ------ 16 files changed, 12 insertions(+), 168 deletions(-) -- 2.3.7
