Subject: [patch 15/15] powerpc: cpumask: Add DEBUG_PER_CPU_MAPS option
Date: Tue, 27 Apr 2010 11:32:46 +1000 [thread overview]
Message-ID: <20100427013432.950809577@samba.org> (raw)
In-Reply-To: 20100427013231.510168034@samba.org
Enable the DEBUG_PER_CPU_MAPS option so we can look for problems with
cpumasks .
