Merge tag 'kgdb-5.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/danielt/linux

Pull kgdb updates from Daniel Thompson:
 "Everything for kgdb this time around is either simplifications or
  clean ups.

  In particular Douglas Anderson's modifications to the backtrace
  machine in the *last* dev cycle have enabled Doug to tidy up some MIPS
  specific backtrace code and stop sharing certain data structures
  across the kernel. Note that The MIPS folks were on Cc: for the MIPS
  patch and reacted positively (but without an explicit Acked-by).

  Doug also got rid of the implicit switching between tasks and register
  sets during some but not of kdb's backtrace actions (because the
  implicit switching was either confusing for users, pointless or both).

  Finally there is a coverity fix and patch to replace open coded
  console traversal with the proper helper function"
