[PATCH 1/1] kvm: Fix build for VT-d/AMD IOMMU

[PATCH 1/1] kvm: Fix build for VT-d/AMD IOMMU

[Sheng Yang]

The vtd.c has renamed to iommu.c, and config option has changed to
CONFIG_IOMMU_API.

Notice now the host kernel before 2.6.29 can't work with VT-d due to API
changed... At least this patch enabled building with host kernel before 2.6.29
with CONFIG_DMAR.
