This series cherry picks checkpatch UTF-8 fixes and the MAINTAINERS file check
from Linux.  Thomas Huth original did the backport in January 2017 but the
series was forgotten (<1485436265-12573-1-git-send-email-thuth@redhat.com>).  I
did the cherry pick again from scratch.

The MAINTAINERS file check prints a warning when new files are added without a
modification to ./MAINTAINERS.  It is easy to forget to update ./MAINTAINERS
and this check should help us stay on top of new source files.

Joe Perches (4):
  checkpatch: add a --strict check for utf-8 in commit logs
  checkpatch: ignore email headers better
  checkpatch: emit a warning on file add/move/delete
  checkpatch: reduce MAINTAINERS update message frequency

Pasi Savanainen (1):
  checkpatch: check utf-8 content from a commit log when it's missing
    from charset
