Also the standard -g compiled lkcd Kerntypes file seems to work, if you
set the KERNTYPES flag. This can be useful, if you don't want to build a
full -g compiled vmlinux.
I used the following simple patch which adds the "-k" option to force
crash using the kerntypes code path.

I attached the kerntypes file, which works for s390:
/*
* kerntypes.c
*
* Dummy module that includes headers for all kernel types of interest.
* The kernel type information is used by the lcrash utility when
* analyzing system crash dumps or the live system. Using the type
* information for the running system, rather than kernel header files,
* makes for a more flexible and robust analysis tool.
