This patch set is for removing 2 flags PCG_FILE_MAPPED and PCG_MOVE_LOCK on page_cgroup->flags. After this, page_cgroup has only 3bits of flags. And, this set introduces a new method to update page status accounting per memcg. With it, we don't have to add new flags onto page_cgroup if 'struct page' has information. This will be good for avoiding a new flag for page_cgroup. Fixed pointed out parts. - added more comments - fixed texts - removed redundant arguments. Passed some tests on 3.3.0-rc3-next-20120216.
