Subject: [PATCH 5/7] [RFC] force 32-byte aligned kmallocs
Date: Wed, 18 May 2011 16:24:53 -0500 [thread overview]
Message-ID: <1305753895-24845-5-git-send-email-ericvh@gmail.com> (raw)
In-Reply-To: <1305753895-24845-1-git-send-email-ericvh@gmail.com>
For BGP, it is convenient for 'kmalloc' to come back with 32-byte
aligned units for torus DMA
