Please always include diffstats in your cover letter, to make it easier
for maintainers to see at a glance how much a series touches their
subsystem.  git-format-patch does it right:

Pavel Butsykin (3):
  hmp-commands-info: move info_cmds content out of monitor.c
  monitor: remove target-specific code from monitor.c
  monitor: added generation of documentation for hmp-commands-info.hx
