Hi Joerg & David,

Bjorn has accepted the above patches for v3.16 and they currently live
in his pci/iommu branch.  This series has been shown by numerous users
to make devices with buggy DMA issues work in the presence of an IOMMU
and it would be really great if we could get an opinion on both the
common IOMMU changes as well as the changes for AMD-Vi and Intel VT-d.
Varun has already ack'd the changes for fsl.  Please let us know how
you'd like to proceed.  Can we get acks and allow Bjorn to shepherd the
whole series in?  Would you prefer to pull the changes via your
respective trees and let Bjorn follow-up with the code removal?  Do you
have any outstanding issues with the patches to your areas?  Thanks,

Alex
