Subject: [PATCH] powerpc: Define cpus_in_crash only for SMP kernels
Date: Wed, 1 Feb 2012 10:55:10 -0800 [thread overview]
Message-ID: <20120201185510.GA8542@linux.vnet.ibm.com> (raw)
The variable cpus_in_crash gets a defined-but-not-used warning when
CONFIG_SMP=n, so fix by placing the variable under ifdef.
