IMO you should leave kdbgetu64arg() the way it was. It is symmetric
to all of the other similar functions and even if there are no
external users of kdbgetu64arg() now it seems like it makes sense to
keep it matching.

Getting rid of kdb_print_nameval() / kdb_meminfo_proc_show() makes sense to me.

Getting rid of kdb_print_nameval() makes sense to me.
