Allow specification of the domain-id for the new domain.
This patch only adds the 'did' parameter to iommu_attach_domain()
and modifies all of its callers to specify the default value of -1
which says "no did specified, allocate a new one".
I think its better to keep the old iommu_attach_domain() interface in
place and introduce a new function (like iommu_attach_domain_with_id()
or something) which has the additional parameter. Then you can rewrite
iommu_attach_domain():
iommu_attach_domai(...)
{
return iommu_attach_domain_with_id(..., -1);
}
This way you don't have to update all the callers of
iommu_attach_domain() and the interface is more readable.

That's a good way. I will do this in next version.
Thanks
