Major changes from v6 is
 a) added documentation about CSS ID.
 b) fixed typos and bugs.
 c) refleshed some comments

based on mmotm-2010-08-27

Patch brief view:
 1. changes css ID allocation in kernel/cgroup.c
 2. use ID-array in memcg.
 3. record ID to page_cgroup rather than pointer.
 4. make update_file_mapped to be RCU aware routine instead of spinlock.
 5. make update_file_mapped as general-purpose function.


Thanks,
-Kame
