The patch titled

     nfs_show_stats: for_each_possible_cpu(), not NR_CPUS

has been added to the -mm tree.  Its filename is

     nfs_show_stats-for_each_possible_cpu-not-nr_cpus.patch

See http://www.zip.com.au/~akpm/linux/patches/stuff/added-to-mm.txt to find
out what to do about this


From: John Hawkes <hawkes@xxxxxxx>

Convert a for-loop that explicitly references "NR_CPUS" into the
potentially more efficient for_each_possible_cpu() construct.
