Jesse, the patch looks good to me, except the task accounting for the page-faults. I'd like to get rid of using task_struct in the IOMMUv2 driver entirely if possible. Also it is not really the CPU task causing the faults, but some non-CPU process. So can you please remove that code and resend the patches with Oded's Tested-by and Andrew Morton on Cc? I think these patches should go through the -mm tree.
