*	iommu: add self-consistency tests to ARM LPAE IO page table allocator	Will Deacon	2015-01-19	1	-1/+199
\| \| \| \| \| \| \| \|	This patch adds a series of basic self-consistency tests to the ARM LPAE IO page table allocator that exercise corner cases in map/unmap, as well as testing all valid configurations of pagesize, ias and stage. Signed-off-by: Will Deacon <will.deacon@arm.com>
*	iommu: add ARM LPAE page table allocator	Will Deacon	2015-01-19	1	-0/+781
	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.
