The patch below has been trivially rebased against 3.12.6, I'm
successfully using it on 3.12.x since mid december.

Subject: [PATCH] drm/nouveau: only runtime suspend by default in optimus
configuration
Date: Wed, 11 Dec 2013 22:19:01 -0500
The intent was to only enable it by default for optimus, e.g. see the
runtime_idle callback. The suspend callback may be called directly, e.g.
as a result of nouveau_crtc_set_config.

See http://lists.freedesktop.org/archives/dri-devel/2013-November/049738.html
for my analysis of the situation. Since this has been around since 3.12, I'm
tagging it for stable.
