Hi everyone, Does someone need anything more to be done regarding this series ?

Hi Michal, This patchset got acked, tested and reviewed by quite a few people, and it has been suggested that it should be included in -mm tree: could you tell me if something else needs to be done for its inclusion ?

Ok, my bad, sorry about that, I have just added Andrew as CC then.

[CC linux-mm for inclusion in -mm tree] In order to reduce copy/paste of functions across architectures and then make riscv hugetlb port (and future ports) simpler and smaller, this patchset intends to factorize the numerous hugetlb primitives that are defined across all the architectures. Except for prepare_hugepage_range, this patchset moves the versions that are just pass-through to standard pte primitives into asm-generic/hugetlb.h by using the same #ifdef semantic that can be found in asm-generic/pgtable.h, i.e. __HAVE_ARCH_***. s390 architecture has not been tackled in this serie since it does not use asm-generic/hugetlb.h at all. This patchset has been compiled on all addressed architectures with success (except for parisc, but the problem does not come from this series). v6: - Remove nohash/32 and book3s/32 powerpc specific implementations in order to use the generic ones. - Add all the Reviewed-by, Acked-by and Tested-by in the commits, thanks to everyone. v5: As suggested by Mike Kravetz, no need to move the #include <asm-generic/hugetlb.h> for arm and x86 architectures, let it live at the top of the file. v4: Fix powerpc build error due to misplacing of #include <asm-generic/hugetlb.h> outside of #ifdef CONFIG_HUGETLB_PAGE, as pointed by Christophe Leroy. v1, v2, v3: Same version, just problems with email provider and misuse of --batch-size option of git send-email Alexandre Ghiti (11): hugetlb: Harmonize hugetlb.h arch specific defines with pgtable.h hugetlb: Introduce generic version of hugetlb_free_pgd_range hugetlb: Introduce generic version of set_huge_pte_at hugetlb: Introduce generic version of huge_ptep_get_and_clear hugetlb: Introduce generic version of huge_ptep_clear_flush hugetlb: Introduce generic version of huge_pte_none hugetlb: Introduce generic version of huge_pte_wrprotect hugetlb: Introduce generic version of prepare_hugepage_range hugetlb: Introduce generic version of huge_ptep_set_wrprotect hugetlb: Introduce generic version of huge_ptep_set_access_flags hugetlb: Introduce generic version of huge_ptep_get arch/arm/include/asm/hugetlb-3level.h | 32 +--------- arch/arm/include/asm/hugetlb.h | 30 ---------- arch/arm64/include/asm/hugetlb.h | 39 +++--------- arch/ia64/include/asm/hugetlb.h | 47 ++------------- arch/mips/include/asm/hugetlb.h | 40 +++---------- arch/parisc/include/asm/hugetlb.h | 33 +++-------- arch/powerpc/include/asm/book3s/32/pgtable.h | 6 -- arch/powerpc/include/asm/book3s/64/pgtable.h | 1 + arch/powerpc/include/asm/hugetlb.h | 43 ++------------ arch/powerpc/include/asm/nohash/32/pgtable.h | 6 -- arch/powerpc/include/asm/nohash/64/pgtable.h | 1 + arch/sh/include/asm/hugetlb.h | 54 ++--------------- arch/sparc/include/asm/hugetlb.h | 40 +++---------- arch/x86/include/asm/hugetlb.h | 69 ---------------------- include/asm-generic/hugetlb.h | 88 +++++++++++++++++++++++++++- 15 files changed, 135 insertions(+), 394 deletions(-)
