Subject: [PATCH 0/4] Implement access checks in iommu page fault paths

Hi,

here is a patch-set that implement proper access checks into
the io-page-fault handlers of the AMD IOMMU and Intel VT-d
drivers.

Two additional patches clean up the AMD part a bit further.
Since I can't test this this code myself due to lack of
hardware or software that utilizes it, I'd appreciate some
external testing.

Oded, David, would you two please test these patches and
report back? Thanks a lot!


	Joerg

  iommu/amd: Do proper access checking before calling handle_mm_fault()
  iommu/amd: Correctly set flags for handle_mm_fault call
  iommu/amd: Cleanup error handling in do_fault()
  iommu/vt-d: Do access checks before calling handle_mm_fault()
