iommu-fixes-v4.7-rc5

Three fixes:

	* Fix use of smp_processor_id() in preemptible code in the IOVA
	  allocation code. This got introduced with the scalability
	  improvements in this release cycle.

	* A VT-d fix for out-of-bounds access of the iommu->domains
	  array. The bug showed during suspend/resume.

	* AMD IOMMU fix to print the correct device id in the ACPI
	  parsing code.
