Subject: [PATCH 0/11] Factor VT-d KVM functions into a generic API

This patch series makes the current KVM device passthrough code generic
enough so that other IOMMU implementation can also plug into this code.
It works by factoring the functions Vt-d code exports to KVM into a
generic interface which allows different backends.

This is the fourth version of the patchset. I rebased these patches onto
the 17-patches post of Han Weidongs multiple device assignment work and
included changes to the commit-messages according the comments I got
from the review.

This a basic implementation of a generic interface. It can and should be
improved later to support more types of hardware IOMMUs then VT-d and
AMD IOMMU.

Since I have no VT-d hardware available these patches are only compile
tested on x86 and ia64 for now.

Please review, comment and test these patches.

Thanks,

Joerg
