Subject: drm: add the base source of the Poulsbo (psb) 2D X11 driver
Date: Fri, 29 Jul 2011 23:17:39 -0500

The complete source of the base (unpatched) psb-kernel-source Poky
package, moved into the kernel tree so it can be build as a
first-class citizen instead of as an external module.  Subsequent
patches will remove the unnecessary parts.

The code here is all the code contained in this tarball:

Date: Fri, 29 Jul 2011 23:21:50 -0500

The default Makefile is meant for building the modules externally.
Replace it with the normal kernel Makefile (Makefile.kernel).

Subject: drm-psb: remove call to agp_flush_chipset
Date: Sun, 31 Jul 2011 00:45:23 -0500

agp_flush_chipset was removed because intel drm calls the chipset
functions directly, and psb doesn't implement a chipset_flush()
function anyway.  Leave drm_agp_flush_chipset exported for modules
that might be expecting it to be there though.

If unset, props.type gets the value 0, which is no longer maps to a
valid type value, so initialize it explicitly.
