Subject: page-allocator: add inactive ratio calculation function of each zone
From: Minchan Kim <minchan.kim@xxxxxxxxx>
Factor the per-zone arithemetic inside setup_per_zone_inactive_ratio()'s
loop into a a separate function, calculate_zone_inactive_ratio(). This
function will be used in a later patch
