Subject[PATCH] [8/11] x86_64: x86_64 - Use non locked version for local_cmpxchg()
Date

From: Mathieu Desnoyers <mathieu.desnoyers@polymtl.ca>
x86_64 - Use non locked version for local_cmpxchg()

local_cmpxchg() should not use any LOCK prefix. This change probably got lost in
the move to cmpxchg.h.
