Subject: [PATCH 1/1] ipr: add writeq definition if needed
Date: Wed, 09 Jun 2010 08:24:55 -0700 [thread overview]
Message-ID: <4C0FB247.7000007@linux.vnet.ibm.com> (raw)
In-Reply-To: <20100608224308.499532262@linux.vnet.ibm.com>
Compiling the driver will fail on 32 bit powerpc and other
architectures where writeq is not defined. This patch adds a
definition for writeq.
