Thanks for testing Oded. 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.

Thanks,

	Joerg
