Hi Joerg and Jesse,
I tested our amdkfd driver with your patches applied (kernel 3.17.1).
I run OpenCL tests, Aparapi/Sumatra (Java) and OpenMP
All tests passed and I didn't see any kernel error messages.
So:

Thanks, I have no way of testing this, but I'm hopeful. :)

Hi Oded,
can you please test these patches with the KFD driver and make sure
nothing breaks for you? I really like this improvement and it would be
great to send it upstream for v3.19.
Thanks,
Joerg

This lets drivers like the AMD IOMMUv2 driver handle faults a bit more
simply, rather than doing tricks with page refs and get_user_pages().
