iommu/vt-d: Update IOMMU state when memory hotplug happens 2014-03-04T16:51:06+00:00 Jiang Liu jiang.liu@linux.intel.com 2014-02-19T06:07:37+00:00 75f05569d0e51f6332a291c82abbeb7c8262e32d If static identity domain is created, IOMMU driver needs to update si_domain page table when memory hotplug event happens.

intel-iommu: Remove superfluous iova_alloc_lock from IOVA code 2009-07-15T07:17:02+00:00 David Woodhouse David.Woodhouse@intel.com 2009-07-08T14:23:30+00:00 3d39cecc4841e8d4c4abdb401d10180f5faaded0 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>
