In the current case the AMD IOMMU driver triggered it on some machines in the IO-page-fault path, so fix it once and for all. ---------------------------------------------------------------- Joerg Roedel (1): iommu: Check dev->iommu in dev_iommu_priv_get() before dereferencing it include/linux/iommu.h | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) Please pull.
