Subject: [PATCH] m68k: skip futex_atomic_cmpxchg_inatomic() test
Date: Thu, 6 Mar 2014 10:29:27 +1100 (EST) [thread overview]
Message-ID: <alpine.LNX.2.00.1403061006440.5525@nippy.intranet> (raw)
In-Reply-To: <alpine.DEB.2.02.1403052254110.18573@ionos.tec.linutronix.de>
Skip the futex_atomic_cmpxchg_inatomic() test in futex_init(). It causes a
fatal exception on 68030 (and presumably 68020 also).
