This patch series enables HugeTLB page migration on POWER platform. This series has some core VM changes (patch 1, 2, 3) and some powerpc specific changes (patch 4, 5, 6, 7, 8, 9, 10). Comments, suggestions and inputs are welcome. Anshuman Khandual (10): mm/mmap: Replace SHM_HUGE_MASK with MAP_HUGE_MASK inside mmap_pgoff mm/hugetlb: Add PGD based implementation awareness mm/hugetlb: Protect follow_huge_(pud|pgd) functions from race powerpc/hugetlb: Add ABI defines for MAP_HUGE_16MB and MAP_HUGE_16GB powerpc/hugetlb: Split the function 'huge_pte_alloc' powerpc/hugetlb: Split the function 'huge_pte_offset' powerpc/hugetlb: Prepare arch functions for ARCH_WANT_GENERAL_HUGETLB powerpc/hugetlb: Selectively enable ARCH_WANT_GENERAL_HUGETLB powerpc/hugetlb: Selectively enable ARCH_ENABLE_HUGEPAGE_MIGRATION selfttest/powerpc: Add memory page migration tests arch/powerpc/Kconfig | 8 + arch/powerpc/include/asm/book3s/64/hash-64k.h | 10 + arch/powerpc/include/uapi/asm/mman.h | 3 + arch/powerpc/mm/hugetlbpage.c | 60 +++--- include/linux/hugetlb.h | 3 + include/linux/mm.h | 33 ++++ mm/gup.c | 6 + mm/hugetlb.c | 75 +++++++- mm/mmap.c | 2 +- tools/testing/selftests/powerpc/mm/Makefile | 14 +- .../selftests/powerpc/mm/hugepage-migration.c | 30 +++ tools/testing/selftests/powerpc/mm/migration.h | 205 +++++++++++++++++++++ .../testing/selftests/powerpc/mm/page-migration.c | 33 ++++ tools/testing/selftests/powerpc/mm/run_mmtests | 104 +++++++++++ 14 files changed, 552 insertions(+), 34 deletions(-) create mode 100644 tools/testing/selftests/powerpc/mm/hugepage-migration.c create mode 100644 tools/testing/selftests/powerpc/mm/migration.h create mode 100644 tools/testing/selftests/powerpc/mm/page-migration.c create mode 100755 tools/testing/selftests/powerpc/mm/run_mmtests -- 2.1.0
