* bonzini/iommu-for-anthony: (22 commits)
  memory: add return value to address_space_rw/read/write
  memory: propagate errors on I/O dispatch
  exec: just use io_mem_read/io_mem_write for 8-byte I/O accesses
  memory: correctly handle endian-swapped 64-bit accesses
  memory: split accesses even when the old MMIO callbacks are used
  memory: add big endian support to access_with_adjusted_size
  memory: accept mismatching sizes in memory_region_access_valid
  memory: add address_space_access_valid
  exec: implement .valid.accepts for subpages
  memory: export memory_region_access_valid to exec.c
  exec: introduce memory_access_size
  exec: introduce memory_access_is_direct
  exec: expect mr->ops to be initialized for ROM
  memory: assign MemoryRegionOps to all regions
  memory: move unassigned_mem_ops to memory.c
  memory: add address_space_translate
  memory: dispatch unassigned accesses based on .valid.accepts
  exec: do not use error_mem_read
  exec: make io_mem_unassigned private
  cputlb: simplify tlb_set_page
