Subject: [GIT PULL] IOMMU fixes for -rc3

Hi Linus,

Please pull these IOMMU fixes for -rc3. It's mainly all Intel VT-D stuff,
but there are some fixes for AMD and ARM as well. We've also got the
revert I promised during the merge window, which removes a temporary
hack to accomodate i915 while we transitioned the Intel IOMMU driver
over to the common DMA-IOMMU API.

Finally, there are still a couple of other VT-D fixes floating around, so I
expect to send you another batch of fixes next week.

Cheers,

Will
