Subject: highmem.c: Use page after it may have been freed
From: Christoph Lameter <clameter@xxxxxxx>
ZVC: highmem.c: Use page after it may have been freed
This is not really a problem since the zone of a page does not
change after it has been freed but its cleaner to use the
page as a reference before it has been freed.
Move the dec_zone_page_state before the free.
