[Xen-devel] [PATCH 1/3] x2APIC/VT-d: allocate iommu when create a drhd

["Han, Weidong" <weidong.han@xxxxxxxxx>]

        A drhd is created when parse ACPI DMAR table, but drhd->iommu is not 
allocated until iommu setup. But iommu is needed by x2APIC which will enable 
interrupt remapping before iommu setup. This patch allocates iommu when create 
drhd. And then drhd->ecap can be removed because it's the same as iommu->ecap.
