These patches include some cleanups and improvements for PCI device hotplug. The most interesting part is the new stats collection facility. Once enabled, the user can see various high-level statistics about what the IOMMU code (mostly limited to DMA-API) is doing in debugfs. This can be used to optimize this and other code (e.g. pv-dma in KVM) in the future.
