In order to encode pc->mem_cgroup and pc->flags to be in a word,
access function to pc->mem_cgroup is required.

This patch replaces access to pc->mem_cgroup with
  pc_to_mem_cgroup(pc)          : pc->mem_cgroup
  pc_set_mem_cgroup(pc, memcg)  : pc->mem_cgroup = memcg

Following patch will remove pc->mem_cgroup.

Kame,

I can't see a reason not to merge this patch right now, regardless of
the other ones.

 
I am not so sure about that. The patch doesn't do much on its own and
reference to the "following patch" might be confusing. Does it actually
help to rush it now?

Hm. it sounds I should post full series (removing RFC) and finish
page cgroup diet all ASAP.

I'll continue updates and tests.

Thanks,
