Subject: [PATCH 1/6] drm/i915: move dev_priv->mm out of line
Date: Wed, 14 Nov 2012 17:14:03 +0100
Message-ID: <1352909648-21514-2-git-send-email-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <1352909648-21514-1-git-send-email-daniel.vetter@ffwll.ch>

Tha one is really big, since it contains tons of comments explaining
how things work. Which is nice ;-)
