Subject[PATCH 0/7] Switch x86 to generic get_user_pages_fast() implementation
Date
Hi,

The patcheset generalize mm/gup.c implementation of get_user_pages_fast()
to be usable for x86 and switches x86 over.

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
