Subject: MIPS: kdb: remove old workaround for backtracing on other CPUs

Patch series "kdb: Don't implicitly change tasks; plus misc fixups".


This patch (of 5):

As of commit 2277b492582d ("kdb: Fix stack crawling on 'running' CPUs that
aren't the master") we no longer need any special case for doing stack
dumps on CPUs that are not the kdb master.  Let's remove.
