  iommu/amd: Introduce protection_domain_init() function (2015-07-01 08:43:07 +0200)

IOMMU Fixes for Linux v4.2-rc0

Four fixes have queued up to fix regressions introduced after v4.1:

	* Don't fail IOMMU driver initialization when the add_device
	  call-back returns -ENODEV, as that just means that the device
	  is not translated by the IOMMU. This is pretty common on ARM.

	* Two fixes for the ARM-SMMU driver for a wrong feature check
	  and to remove a redundant NULL check.

	* A fix for the AMD IOMMU driver to fix a boot panic on systems
	  where the BIOS requests Unity Mappings in the IVRS table.
