Joerg Roedel 7b5cc1a9c9 iommu/amd: Do proper access checking before calling handle_mm_fault() 
The handle_mm_fault function expects the caller to do the
access checks. Not doing so and calling the function with
wrong permissions is a bug (catched by a BUG_ON).
So fix this bug by adding proper access checking to the io
page-fault code in the AMD IOMMUv2 driver.
