Subject: [PATCH 3.10 38/41] m68k: Skip futex_atomic_cmpxchg_inatomic() test

3.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Finn Thain <fthain@...egraphics.com.au>

commit e571c58f313d35c56e0018470e3375ddd1fd320e upstream.

Skip the futex_atomic_cmpxchg_inatomic() test in futex_init(). It causes a
fatal exception on 68030 (and presumably 68020 also).
