    iommu: Change trace unmap api to report unmapped size · db8614d3
    Shuah Khan authored
    Currently map and unmap are implemented as events under a
    common trace class declaration. The common class forces
    trace_unmap() to require a bogus physical address argument
    that it doesn't use. Changing unmap to report unmapped size
    will provide useful information for debugging. Remove common
    map_unmap trace class and change map and unmap into separate
    events as opposed to events under the same class to allow for
    differences in the reporting information. In addition, map and
    unmap are changed to handle size value as size_t instead of int
    to match the passed size value and avoid overflow.
