Subject: [PATCH] fix WARN() for PPC
Date: Mon, 20 Oct 2008 14:50:56 -0700	[thread overview]
Message-ID: <20081020145056.24d84992@infradead.org> (raw)

Subject: [PATCH] fix WARN() for PPC

powerpc doesn't use the generic WARN_ON infrastructure. The newly introduced WARN()
as a result didn't print the message, this patch adds the printk for this specific case.
