iommu: add ARM LPAE page table allocator 2015-01-19T14:46:44+00:00 Will Deacon will.deacon@arm.com 2014-11-14T17:18:23+00:00 e1d3c0fd701df831169b116cd5c5d6203ac07f70 A number of IOMMUs found in ARM SoCs can walk architecture-compatible page tables. This patch adds a generic allocator for Stage-1 and Stage-2 v7/v8 long-descriptor page tables. 4k, 16k and 64k pages are supported, with up to 4-levels of walk to cover a 48-bit address space.
