Hi,
here is the second version of the patch-set to 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.
It took me a while to get these out, mostly because I tried to setup my own HSA test environment to at least test the AMD changes myself. That failed, so I am sending this out with another request for testing.
Oded, Jesse, would you two please test these patches and report back? Thanks a lot!
Joerg
