Inlining pfn_to_nid() yields:
c013e420 9 1.53846 pte_try_to_share
c0132e6c 10 1.7094 filemap_nopage
c0145850 10 1.7094 page_add_rmap
c0133658 13 2.22222 generic_file_aio_write_nolock
c01352d8 14 2.39316 buffered_rmqueue
c0140e40 17 2.90598 do_no_page
c0140b50 18 3.07692 do_anonymous_page
c01411bc 18 3.07692 handle_mm_fault
c011a820 19 3.24786 scheduler_tick
c01172d0 21 3.58974 do_page_fault
Looks good to me. No obvious difference in compile time, though.
