Merge tag 'kgdb-5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/danielt/linux

Pull kgdb updates from Daniel Thompson:
 "Mostly cleanups but there are also a couple of fixes for out-of-bounds
  accesses (including a potential write to the byte before a static
  buffer).

  The main changes are:

   - Fixes to those out-of-bounds access (empty string to configure test
     module could write the byte before a buffer, high cpu counts could
     read outside of per-cpu structures).

   - Improvements to string handling problems picked up by new compiler
     warnings and other static checks. Most are fixing benign issues
     that can't be tickled without code changes but still reduce the wtf
     factor a little.

   - Tidy up the terminal output"
