Subject: [PATCH] fix unused variable without softlock detection and highmem
Date: Mon, 23 Feb 2009 17:39:51 +0530 [thread overview]
Message-ID: <200902231739.51863.knikanth@suse.de> (raw)
When both CONFIG_DETECT_SOFTLOCKUP and CONFIG_HIGHMEM are not defined
avoid defining the constant for one fixing the 'define but not used' warning.
