    Subject[PATCH 1/1] iommu: add a dma remap fault reason.
    Date
    The number of dma fault reasons in intel's document are from 1 to 0xD, but in dmar.c I cannot find fault reason 0xD.

    In this document:
    Intel Virtualization Technology for Directed I/O Architecture Specification
    http://download.intel.com/technology/computing/vptech/Intel(r)_VT_for_Direct_IO.pdf

    Chapter 4. Support For Device-IOTLBs

    Table 6. Unsuccessful Translated Requests

    There is fault reason for 0xD not listed in kernel:
    Present context-entry used to process translation request
    specifies blocking of Translation Requests (Translation Type (T)
    field value not equal to 01b).

    So I think 0xD should be added.
