This patch seems to help in some cases. Before applying this patch I
was able to trigger alloc failures on different machine by booting
kernel with "mem=256MB" and doing:

$ gitk on-full-tree &
# rmmod e100
... wait for few MBs in swap
# modprobe e100; ifup --force ethX

So here this patch helped -- with it, I was unable to trigger page
allocation failures (testing was short, tough). However, as I said
here[1], I applied both of Mel's patches (including this one) and that
didn't help my orginal issue (failures after suspend).

Thanks.
