Subject: [PATCH 0/2] locking/xchg/alpha: Additional fixes

Hi,

A couple of two more fixes, on top of tip:locking/urgent, to Alpha's
implementations of xchg() and cmpxchg():

- The first, suggested by Will, removing the macro '__ASM__MB'
in favour of smp_mb();

- The second, reported by Will, adding a leading smp_mb().

Compile tested only.

Cheers,
Andrea

locking/xchg/alpha: Use smp_mb() in place of __ASM__MB
locking/xchg/alpha: Add leading smp_mb() to xchg(), cmpxchg()
