[PATCH] atomic_inc_return() for arm[3/5] (Re: atomic_inc_return)

[Kaigai Kohei]

[3/5] atomic_inc_return-linux-2.6.9-rc1.arm.patch
  This patch declares atomic_inc_return() as the alias of atomic_add_return()
  and atomic_dec_return() as an alias of atomic_dec_return().
  This patch has not been tested, since we don't have ARM machine.
  I want to let this reviewed by ARM specialists.
