thanks, applied.

It even reduces the size of the kernel a tiny bit:

   text    data     bss     dec     hex filename
   2963    4149    4352   11464    2cc8 numa_64.o.before
   2949    4149    4352   11450    2cba numa_64.o.after

and it's always a good sign to kernel quality when patches (that change 
functionality) have that effect :)
