  kdb: Use for_each_console() helper (2020-01-31 17:34:54 +0000)

----------------------------------------------------------------
kgdb patches for 5.6-rc1

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.
