[PATCH 00/20] iommu/amd: Use generic IOVA allocator
Hi, here is a patch-set to make the AMD IOMMU driver use the generic IOVA allocator, which is already used in the Intel VT-d driver and a few other places. The main reason for the conversion is to make the driver benefit from the recent scalability improvements to the IOVA code. Some of these improvements happened in the Intel VT-d driver, these are not re-used but, for now, re-implemented. This leaves more room for merging things together into common code for the future. The allocator that was previously used will be removed with these patches. Please review.
