# By Paolo Bonzini (11) and others
# Via Paolo Bonzini
* bonzini/iommu-for-anthony:
  memory: clean up phys_page_find
  memory: populate FlatView for new address spaces
  memory: limit sections in the radix tree to the actual address space size
  s390x: reduce TARGET_PHYS_ADDR_SPACE_BITS to 62
  memory: fix address space initialization/destruction
  memory: make memory_global_sync_dirty_bitmap take an AddressSpace
  memory: do not duplicate memory_region_destructor_none
  memory: Rename readable flag to romd_mode
  memory: Replace open-coded memory_region_is_romd
  memory: allow memory_region_find() to run on non-root memory regions
  memory: assert that PhysPageEntry's ptr does not overflow
  exec: eliminate stq_phys_notdirty
  exec: make qemu_get_ram_ptr private
  exec: eliminate qemu_put_ram_ptr
  exec: remove obsolete comment
