kgdb patches for 5.4-rc1 

It has been a quiet dev cycle for kgdb. There has been some good stuff
 for kdb on the mailing list but unfortunately the patches caused a
 couple of problems with the kdb pager so I had to drop those and they
 will have to wait for next time!
 
 That just leaves us with just a couple of very tiny clean ups for now:
 
  * Fix a broken comment
  * Use str_has_prefix() for the grep "pipe" in kdb
