Subject: swap_prefetch: conversion of nr_unstable to per zone counter
From: Christoph Lameter <clameter@xxxxxxx>
Conversion of nr_unstable to a per zone counter
Avoids looping over processor to establish writeback state.
This converts the last critical page state for the VM and therefore
GET_PAGE_STATE_LAST becomes invalid. The next patch is needed to make the
kernel compile again.
