Merge tag 'md/4.5' of git://neil.brown.name/md

Pull md updates from Neil Brown:
 "Mostly clustered-raid1 and raid5 journal updates.  one Y2038 fix and
  other minor stuff.

  One patch removes me from the MAINTAINERS file and adds a record of my
  md maintainership to Credits"

Many thanks to Neil, who has been around for a _looong_ time.
