Subject: Add cmpxchg_local to sparc64
From: Mathieu Desnoyers <mathieu.desnoyers@polymtl.ca>

Use cmpxchg_u32 and cmpxchg_u64 for cmpxchg_local and cmpxchg64_local.  For
other type sizes, use the new generic cmpxchg_local (disables interrupt).

Change:
Since the header depends on local_irqsave/local_irqrestore, it must be
included after their declaration.

Actually, being below the
#include <linux/irqflags.h> should be enough, and on sparc64 it is
included at the beginning of system.h.

So it makes sense to move it up for sparc64.
