  icount: possible options for sleep are on or off
  exec: Introduce AddressSpaceDispatch.mru_section
  exec: Factor out section_covers_addr
  exec: Pass RAMBlock pointer to qemu_ram_free
  memory: Drop MemoryRegion.ram_addr
  memory: Implement memory_region_get_ram_addr with mr->ram_block
  memory: Move assignment to ram_block to memory_region_init_*
  exec: Return RAMBlock pointer from allocating functions
