x86: make GART to respect device's dma_mask about virtual mappings
Currently, GART IOMMU ingores device's dma_mask when it does virtual mappings. So it could give a device a virtual address that the device can't access to. This patch fixes the above problem. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Signed-off-by: Ingo Molnar <mingo@elte.hu>
