* remotes/bonzini/tags/for-upstream:
  hostmem: detect host backend memory is being used properly
  hostmem: fix QEMU crash by 'info memdev'
  char: do not use atexit cleanup handler
  net: do not use atexit for cleanup
  slirp: use exit notifier for slirp_smb_cleanup
  tap: use an exit notifier to call down_script
  util: Fix MIN_NON_ZERO
  qemu-sockets: use qapi_free_SocketAddress in cleanup
  disas: avoid including everything in headers compiled from C++
  json-streamer: fix double-free on exiting during a parse
  main-loop: check return value before using pointer
  Use "-s" instead of "--quiet" to resolve non-fatal build error on FreeBSD.
  scsi-bus: Use longer sense buffer with scanners
  scsi-bus: Add SCSI scanner support
