Subject: [PATCH] powerpc: fix spider-pic affinity setting
Date: Fri, 24 Mar 2006 19:46:29 +0100 [thread overview]
Message-ID: <200603241946.30419.arnd.bergmann@de.ibm.com> (raw)
In-Reply-To: <200603241905.04356.arnd.bergmann@de.ibm.com>
As noticed by Milton Miller, setting the initial affinity in
spider-pic can go wrong if the target node field was not orinally
empty.
