x86, gart: Set DISTLBWALKPRB bit always The DISTLBWALKPRB bit must be set for the GART because the gatt table is mapped UC. But the current code does not set the bit at boot when the BIOS setup the aperture correctly. Fix that by setting this bit when enabling the GART instead of the other places.

x86, GART: Disable GART table walk probes Current code tramples over bit F3x90[6] which can be used to disable GART table walk probes. However, this bit should be set for performance reasons (speed up GART table walks). We are allowed to do that since we put GART tables in UC memory later anyway. Make it so.

x86, iommu: Make all IOMMU's detection routines return a value. We return 1 if the IOMMU has been detected. Zero or an error number if we failed to find it. This is in preperation of using the IOMMU_INIT so that we can detect whether an IOMMU is present. I have not tested this for regression on Calgary, nor on AMD Vi chipsets as I don't have that hardware. CC: Muli Ben-Yehuda <muli@il.ibm.com> CC: "Jon D. Mason" <jdmason@kudzu.us> CC: "Darrick J.

x86: GART: Convert gart_iommu_hole_init() to use iommu_init hook This changes gart_iommu_hole_init() to set gart_iommu_init() to iommu_init hook if gart_iommu_hole_init() finds the GART IOMMU. We can kill the code to check if we found the IOMMU in gart_iommu_init() since gart_iommu_hole_init() sets gart_iommu_init() only when it found the IOMMU.

x86: Use x86_platform for iommu_shutdown This patch cleans up pci_iommu_shutdown() a bit to use x86_platform (similar to how IA64 initializes an IOMMU driver). This adds iommu_shutdown() to x86_platform to avoid calling every IOMMUs' shutdown functions in pci_iommu_shutdown() in order. The IOMMU shutdown functions are platform specific (we don't have multiple different IOMMU hardware) so the current way is pointless. An IOMMU driver sets x86_platform.iommu_shutdown to the shutdown function if necessary.
