Hi Paul,

This patch has already been merged by me in the userspace RCU library:

commit e72f49371b233637eaf143265a73c7322d0710fd
Author: Paul E. McKenney <paulmck@...ux.vnet.ibm.com>
Date:   Wed Sep 23 03:09:59 2009 -0400

    ppc atomic: Fix asm format.
    
    Signed-off-by: Paul E. McKenney <paulmck@...ux.vnet.ibm.com>
    Signed-off-by: Mathieu Desnoyers <mathieu.desnoyers@...ymtl.ca>

It's therefore already integrated in the current releases.

Thanks,

Mathieu
