drm/i915: implement BSD ring buffer V2
The BSD (bit stream decoder) ring is used for accessing the BSD engine
which decodes video bitstream for H.264 and VC1 on G45+. It is
asynchronous with the render ring and has access to separate parts of
the GPU from it, though the render cache is coherent between the two.

git revert didn't work on 2.6.35-rc6 so I just changed the HAS_BSD thing to:
#define HAS_BSD(dev) (0)
with this change applied suspend to ram is back to the reliability of 2.6.34.y
with kind regards

Added CCs.
Thomas, on what hardware did you observe the regression?
Is a Intel mobile express gm45 chipset.
Is it suspend
or resume that is unreliable?
suspend never finishes/hangs.
What are the particular symptoms --- does
not suspend, crashes during suspend, crashes during resume...?
Does not suspend, backlight is on.
Could you help report a bug for this issue by following
