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.
