    Subject[92/99] x86/amd-iommu: Un__init function required on shutdown
    2.6.31-stable review patch.  If anyone has any objections, please let us know.

    From: Joerg Roedel <>

    commit ca0207114f1708b563f510b7781a360ec5b98359 upstream.

    The function iommu_feature_disable is required on system
    shutdown to disable the IOMMU but it is marked as __init.
    This may result in a panic if the memory is reused. This
    patch fixes this bug.
