Subject: [PATCH 4/7] ARM: panic on div 0
Date: Thu, 26 Jan 2012 14:26:50 +0100	[thread overview]
Message-ID: <1327584413-23055-5-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1327584413-23055-1-git-send-email-s.hauer@pengutronix.de>

hang() only outputs 'reset the board' whereas panic
can be passed a string which we can use to output
some more information what is happening.
