Subject: [PATCH-WIP 04/13] xen/arm: sync_bitops
Date: Thu, 23 Feb 2012 17:48:25 +0000 [thread overview]
Message-ID: <1330019314-20865-4-git-send-email-stefano.stabellini@eu.citrix.com> (raw)
In-Reply-To: <alpine.DEB.2.00.1202231714590.23091@kaball-desktop>
sync_bitops functions are equivalent to the SMP implementation of the
original functions, independently from CONFIG_SMP being defined.
