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
