  hmp: info migrate_parameters format tunes
  hmp: info migrate_capability format tunes
  migration: rename max_size to threshold_size
  migration: set current_active_state once
  virtio-rng: stop virtqueue while the CPU is stopped
  migration: don't close a file descriptor while it can be in use
  ram: Remove migration_bitmap_extend()
  migration: Disable hotplug/unplug during migration
  qdev: Move qdev_unplug() to qdev-monitor.c
  qdev: Export qdev_hot_removed
  qdev: qdev_hotplug is really a bool
  migration: Remove MigrationState parameter from migration_is_idle()
  ram: Use RAMBitmap type for coherence
  ram: rename last_ram_offset() last_ram_pages()
  ram: Use ramblock and page offset instead of absolute offset
  ram: Change offset field in PageSearchStatus to page
  ram: Remember last_page instead of last_offset
  ram: Use page number instead of an address for the bitmap operations
  ram: reorganize last_sent_block
