Pull IOMMU fixes from Joerg Roedel:

 - Revert an Intel VT-d patch that caused problems for some users.

 - Removal of a feature in the Intel VT-d driver that was never
   supported in hardware. This qualifies as a fix because the code for
   this feature sets reserved bits in the invalidation queue descriptor,
   causing failed invalidations on real hardware.

 - Two fixes for AMD IOMMU driver to fix a race condition and to add a
   missing IOTLB flush when kernel is booted in kdump mode.
