Hi Paul,
This patch has already been merged by me in the userspace RCU library:
commit e72f49371b233637eaf143265a73c7322d0710fd
Author: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
Date: Wed Sep 23 03:09:59 2009 -0400
ppc atomic: Fix asm format.
Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
Signed-off-by: Mathieu Desnoyers <mathieu.desnoyers@polymtl.ca>
It's therefore already integrated in the current releases.
Thanks,
Mathieu

Maybe you did a make install that got the headers installed system-wide, and the
search order is wrong ? (just a thought)
Did you build 0.5.2 from the tarballs or from the git repo ?
