Convert to the much saner new idr interface.
Only compile tested.
Signed-off-by: Tejun Heo tj@kernel.org Cc: David Airlie airlied@linux.ie Cc: Daniel Vetter daniel.vetter@ffwll.ch Cc: dri-devel@lists.freedesktop.org --- This patch depends on an earlier idr changes and I think it would be best to route these together through -mm. Please holler if there's any objection. Thanks.
