drm/i915: Fix gen2 mappable calculations
When I refactored the code initially, I forgot that gen2 uses a different bar for the CPU mappable aperture. The agp-less code knows nothing of generations less than 5, so we have to expand the gtt_probe function to include the mappable base and end. It was originally broken by me: commit baa09f5fd8a6d033ec075355dda99a65b7f6a0f3 Author: Ben Widawsky <ben@bwidawsk.net> Date: Thu Jan 24 13:49:57 2013 -0800 drm/i915: Add probe and remove to the gtt ops Reported-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Ben Widawsky <ben@bwidawsk.net> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
