Jiang Liu	75f05569d0	iommu/vt-d: Update IOMMU state when memory hotplug happens ... If static identity domain is created, IOMMU driver needs to update si_domain page table when memory hotplug event happens. Otherwise PCI device DMA operations can't access the hot-added memory regions.

David Woodhouse	3d39cecc48	intel-iommu: Remove superfluous iova_alloc_lock from IOVA code ... We only ever obtain this lock immediately before the iova_rbtree_lock, and release it immediately after the iova_rbtree_lock. So ditch it and just use iova_rbtree_lock. [v2: Remove the lockdep bits this time too] Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>	2009-07-15 08:17:02 +01:00
