Subject: [PATCH 0/2] locking/xchg/alpha: Additional fixes
Date: Thu, 22 Feb 2018 10:23:41 +0100 [thread overview]
Message-ID: <1519291421-5638-1-git-send-email-parri.andrea@gmail.com> (raw)
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
Andrea Parri (2):
locking/xchg/alpha: Use smp_mb() in place of __ASM__MB
locking/xchg/alpha: Add leading smp_mb() to xchg(), cmpxchg()
