[Qemu-devel] [PATCH 00/21] Memory/IOMMU patches, part 3: IOMMU implementation

[Paolo Bonzini]

This part includes Jan's subpage reorganization (needed to unify MMIO
and PIO dispatch) and the implementation of IOMMU regions.  Compared to
previous submissions, there is full support for 64-bit-sized IOMMU
regions, so I'm reverting the patches from part 1 that reduced the
maximum size of sections to 62 bits.

Patches 1-10 are the new ones.

Alexey Kardashevskiy (1):
  memory: give name to every AddressSpace

Avi Kivity (3):
  memory: iommu support
  vfio: abort if an emulated iommu is used
  pci: use memory core for iommu support

David Gibson (1):
  memory: Add iommu map/unmap notifiers

Jan Kiszka (4):
  memory: Introduce address_space_lookup_region
  exec: Allow unaligned address_space_rw
  exec: Resolve subpages in one step except for IOTLB fills
  exec: Implement subpage_read/write via address_space_rw

Paolo Bonzini (12):
  memory: move private types to exec.c
  exec: return MemoryRegion from address_space_translate
  Revert "memory: limit sections in the radix tree to the actual address
    space size"
  Revert "s390x: reduce TARGET_PHYS_ADDR_SPACE_BITS to 62"
  exec: reorganize mem_add to match Int128 version
  memory: make section size a 128-bit integer
  spapr: convert TCE API to use an opaque type
  spapr: make IOMMU translation go through IOMMUTLBEntry
  spapr: use memory core for iommu support
  dma: eliminate old-style IOMMU support
  spapr_vio: take care of creating our own AddressSpace/DMAContext
  dma: eliminate DMAContext
