Version 2 incorporating acks and feedback from v1.  The PCI DMA quirk
and ACS check are reworked, sysfs iommu groups ABI Documentation
added as well as numerous other fixes, including patches from Alexey
Kardashevskiy towards supporting POWER usage of VFIO and IOMMU groups.

This series can be found here on top of 3.4:

git://github.com/awilliam/linux-vfio.git iommu-group-vfio-20120521

The Qemu tree has also been updated to Qemu 1.1 and can be found here:

git://github.com/awilliam/qemu-vfio.git iommu-group-vfio

I'd really like to make a push to get this in for 3.5, so let's talk
about how to do that across iommu, pci, and new driver.  Joerg, are
you sufficiently happy with the IOMMU group concept and code?  We'll
also need David Woodhouse buyin on the intel-iommu changes in patches
3 & 6.  Who needs to approve VFIO as a new driver, GregKH?  Bjorn,
I'd be happy to send the PCI changes as a series for you, but I
wonder if it makes sense to collect acks for them if you approve and
bundle them in with the associated code that needs them so you're
not left with unused code.  Let me know which you prefer.  If there
are better ways to do it, please let me know.  Thanks,

Alex
