Subject: [PATCH] atomic_inc_return() for sparc64[5/5] (Re: atomic_inc_return)

[5/5] atomic_inc_return-linux-2.6.9-rc1.sparc64.patch
This patch declares atomic_add_return() as an alias of __atomic_add().
atomic64_add_return(),atomic_sub_return() and atomic64_sub_return() are same.
This patch has not been tested, since we don't have SPARC64 machine.
I want to let this reviewed by SPARC64 specialists.
