[PATCH v2 0/2] memcg: variable type fixes

[Greg Thelen]

This is a two part series that is a cleanup of memcg internal
counters.  These two patches were originally proposed by Johannes
Weiner [1].  The original series was based on an older mmotm, so I had
to massage the patches a little.  The patches are now based on
mmotm-2011-02-10-16-26.

Patch 1 implements the idea that memcg only has to use signed types
for some of the counters, but not for the constant monotonically
increasing event counters where the sign-bit is a waste.
Originally proposed in [2].
  
Patch 2 converts the memcg fundamental page statistics counters to
native words as they should be wide enough for the expected values.
Originally proposed in [3].
