[Xen-devel] [PATCH] vt-d: fix Dom0 S3 resume.

["Cui, Dexuan" <dexuan.cui@xxxxxxxxx>]

When resuming from Dom0 S3, here 'irq' is -1, so we can't use it at all.
We should always use iommu->irq.

With the patch applied on the current tip 20153 and using the 2.6.18 Dom0,
Dom0 S3 works fine (at least on my DQ35). 
 

Thanks,
-- Dexuan
