Subject: [PATCH 0/5] kdb: Don't implicitly change tasks; plus misc fixups

This started out as just a follow-up to Daniel's post [1].  I wanted
to stop implicitly changing the current task in kdb.  ...but, of
course, everywhere you look in kdb there are things to cleanup, so
this gets a few misc cleanups I found along the way.  Enjoy.

Douglas Anderson (5):
  MIPS: kdb: Remove old workaround for backtracing on other CPUs
  kdb: kdb_current_regs should be private
  kdb: kdb_current_task shouldn't be exported
  kdb: Gid rid of implicit setting of the current task / regs
  kdb: Get rid of confusing diag msg from "rd" if current task has no
    regs
