Considering that the only (current) caller of this it domain_build.c I'm afraid you're going to get into trouble if you get back -ERESTART here. Note that on x86 Dom0 setup works via iommu_hwdom_init(), which deals with the preemption needs (at that point in time) by calling process_pending_softirqs() every once in a while.
