This makes me wonder when we're going to get these definitions in the kernel
source, and have people running around making the conversion:

#define ZERO 0
#define ONE 1
#define TWO 2
#define THREE 3
#define FOUR 4
...

because allegedly it makes it more "readable".  I don't see much benefit
to this patch.
