[PATCH] x86_64: Calgary IOMMU - IOMMU abstractions
This patch creates a new interface for IOMMUs by adding a centralized location for IOMMU allocation (for translation tables/apertures) and IOMMU initialization. In creating these, code was moved around for abstraction, uniformity, and consiceness. Take note of the move of the iommu_setup bootarg parsing code to __setup. This is enabled by moving back the location of the aperture allocation/detection to mem init (which while ugly, was already the location of the swiotlb_init). While a slight departure from the previous patch, I belive this provides the true intention of the previous versions of the patch which changed this code. It also makes the addition of the upcoming calgary code much cleaner than previous patches. [AK: Removed one broken change. iommu_setup still has to be called early] Signed-off-by: Muli Ben-Yehuda <muli@il.ibm.com> Signed-off-by: Jon Mason <jdmason@us.ibm.com> Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
