    Subject[PATCH 0/3] fix GART to respect device's dma_mask about virtual mappings
    Currently, gart IOMMU ignores 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.

    Some IOMMUs, in x86 IOMMUs GART and Calgary, have this issue. This
    patchset fixes GART.

    The first and second patches add helper functions, useful for some
    IOMMUs (both are taken from POWER IOMMU code). I'll convert some
    IOMMUs to use the functions after they are merged into mainline (to
    avoid complicated dependence on multiple trees).

    This is against tip/x86/iommu plus a patch that I sent yesterday:
