Please review and consider applying. Kirill A. Shutemov (7): mm: Drop arch_pte_access_permitted() mmu hook mm/gup: Move permission checks into helpers mm/gup: Move page table entry dereference into helper mm/gup: Make pages referenced during generic get_user_pages_fast() mm/gup: Implement dev_pagemap logic in generic get_user_pages_fast() mm/gup: Provide hook to check if __GUP_fast() is allowed for the range x86/mm: Switch to generic get_user_page_fast() implementation arch/powerpc/include/asm/mmu_context.h | 6 - arch/s390/include/asm/mmu_context.h | 6 - arch/um/include/asm/mmu_context.h | 6 - arch/unicore32/include/asm/mmu_context.h | 6 - arch/x86/Kconfig | 3 + arch/x86/include/asm/mmu_context.h | 16 - arch/x86/include/asm/pgtable-3level.h | 45 +++ arch/x86/include/asm/pgtable.h | 53 ++++ arch/x86/include/asm/pgtable_64.h | 16 +- arch/x86/mm/Makefile | 2 +- arch/x86/mm/gup.c | 496 ------------------------------- include/asm-generic/mm_hooks.h | 6 - include/asm-generic/pgtable.h | 25 ++ include/linux/mm.h | 4 + mm/gup.c | 134 +++++++-- 15 files changed, 262 insertions(+), 562 deletions(-) delete mode 100644 arch/x86/mm/gup.c -- 2.11.0
