Subject: [PATCH] [mmotm 0113] memcg: fix compile error


This issue was introduced by memcg-move-charges-of-anonymous-swap.patch.

=================================
Now, ia64 can't compile page_cgroup.c.
because it include asm/cmpxhg.h but almost arch don't have arch specific
cmpxhg.h. they use asm-generic/cmpxhg.h.

Then, following errror occur.

  CC      mm/page_cgroup.o
  mm/page_cgroup.c:12:25: error: asm/cmpxchg.h: No such file or
  directory
  make[1]: *** [mm/page_cgroup.o] Error 1
  make: *** [mm] Error 2

Fortunately, memcg code don't use low layer cmpxchg directly. thus
this patch remove this include line simply.
