Patches 1-10 are small changes, some of them bugfixes for the IOMMU portion of the patches.
Patches 11-13 introduce three new address_space APIs and clean up the dispatch logic a bit by removing memory_region_section_addr. Patches 14-22 introduce IOMMU memory regions, convert sPAPR to the new API, and finally eliminate DMAContext in favor of AddressSpace. Patches 24-37 set an owner on all regions owned by hot-unpluggable devices (and several others when that was easy), and add ref/unref calls that keep the regions alive even if the owner is hot-unplugged. Patches 38-40 make memory_region_find safe for usage outside the BQL. These patches are also at git://github.com/bonzini/qemu.git, branch iommu. Please review!
