[PATCH 09/10] x86/VT-d: Make Intel VT-d IOMMU use IOMMU_INIT_* macros.

From: Konrad Rzeszutek Wilk
Date: Thu Aug 26 2010 - 13:59:42 EST


We utilize the IOMMU_INIT macros to create this dependency:

[null]
|
[pci_xen_swiotlb_detect]
|
[pci_swiotlb_detect_override]
|
[pci_swiotlb_detect_4gb]
|
+-------+--------+---------------------+
/ \ \
[detect_calgary] [gart_iommu_hole_init] [detect_intel_iommu]
|
[amd_iommu_detect]
