Hi Jason. I noticed that your code assumes zones begin on well
aligned physical addresses. This is not true.
For example, in page_color_start you use the raw
(page - zone->zone_mem_map) index as the color. This
is wrong, what if the zone starts at page 1? In such
a case all of your colors will be computed incorrectly
and pages with different colors in different zones can actually be of
the same color.
