I am not fluent in the gdb macros and python so I did not try any
deep review. But both patches work for me:

Tested-by: Petr Mladek <pmladek@...e.com>

I am going to give it few more days before pushing just in case there is
another feedback.

BTW: Are you aware of https://github.com/crash-python/crash-python project?
     The ambition is to implement "crash" features and even more into
     gdb using python extensions. It similar approach like
     scripts/gdb/

     crash-python is being developed sporadically in waves. It is
     mostly during a week that is dedicated for such projects
     at SUSE. It would be great to get more contributors.
