* remotes/bonzini/tags/for-upstream:
  target-i386: fix confusion in xcr0 bit position vs. mask
  chardev: Properly initialize ChardevCommon components
  memory: Remove unreachable return statement
  memory: optimize qemu_get_ram_ptr and qemu_ram_ptr_length
  exec: store RAMBlock pointer into memory region
  log: Redirect stderr to logfile if deamonized
  dump-guest-memory: add qmp event DUMP_COMPLETED
  Dump: add hmp command "info dump"
  Dump: add qmp command "query-dump"
  DumpState: adding total_size and written_size fields
  dump-guest-memory: add "detach" support
  dump-guest-memory: disable dump when in INMIGRATE state
  dump-guest-memory: introduce dump_process() helper function.
  dump-guest-memory: add dump_in_progress() helper function
  dump-guest-memory: using static DumpState, add DumpStatus
  dump-guest-memory: add "detach" flag for QMP/HMP interfaces.
  dump-guest-memory: cleanup: removing dump_{error|cleanup}().
