IOMMU Fixes for Linux v4.3-rc7
Two late fixes for the AMD IOMMU driver:
* One adds an additional check to the io page-fault handler to
avoid a BUG_ON being hit in handle_mm_fault()
* Second patch fixes a problem with devices writing to the
system management area and were blocked by the IOMMU because
the driver wrongly cleared out the DTE flags allowing that
access.
