[PATCH] A code cleanup change

[Rajagopal Ananthanarayanan <ananth@sgi.com>]

A simple change to get rid of a few magic numbers.
Not included in the patch, one could also use a simple array
for the triplet page_{min,low,high} with the same PAGE_{MIN,LOW,HIGH} index
definitions. The switch in __alloc_pages_limit will be
gone; other places will have to be modified, but
won't incur any extra cost.

Patch against test9-pre7:
