#     Merge tag 'kgdb-5.8-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/danielt/linux
#     
#     Pull kgdb fixes from Daniel Thompson:
#      "The main change here is a fix for a number of unsafe interactions
#       between kdb and the console system. The fixes are specific to kdb
#       (pure kgdb debugging does not use the console system at all). On
#       systems with an NMI then kdb, if it is enabled, must get messages to
#       the user despite potentially running from some "difficult" calling
#       contexts. These fixes avoid using the console system where we have
#       been provided an alternative (safer) way to interact with the user
#       and, if using the console system in unavoidable, use oops_in_progress
#       for deadlock avoidance. These fixes also ensure kdb honours the
#       console enable flag.
#     
#       Also included is a fix that wraps kgdb trap handling in an RCU read
#       lock to avoids triggering diagnostic warnings. This is a wide lock
#       scope but this is OK because kgdb is a stop-the-world debugger. When
#       we stop the world we put all the CPUs into holding pens and this
#       inhibits RCU update anyway"
