Merge branch 'upstream' into bugfix-video

Update bugfix-video branch to 2.5-rc1
so I don't have to again resolve the
conflict in these patches vs. upstream.

Conflicts:
	drivers/gpu/drm/gma500/psb_drv.c

	text conflict: add comment vs delete neighboring line

	keep just this:
	/* igd_opregion_init(&dev_priv->opregion_dev); */
	/* acpi_video_register(); */
