  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
