David Woodhouse fc61901373 agp/intel-agp: Clear entire GTT on startup 
Some BIOSes fail to initialise the GTT, which will cause DMA faults when
the IOMMU is enabled. We need to clear the whole thing to point at the
scratch page, not just the part that Linux is going to use.

driver bugs, by not drawing to memory we don't own]
