    iommu: Add config option to set passthrough as default · 58d11317
    Olof Johansson authored
    This allows the default behavior to be controlled by a kernel config
    option instead of changing the commandline for the kernel to include
    "iommu.passthrough=on" or "iommu=pt" on machines where this is desired.
    
    Likewise, for machines where this config option is enabled, it can be
    disabled at boot time with "iommu.passthrough=off" or "iommu=nopt".
    
    Also corrected iommu=pt documentation for IA-64, since it has no code that
    parses iommu= at all.
