Should be done for all architectures, methinks.
If so, an appropriate way to do that would be to do s/dump_stack/arch_dump_stack/ and do a single all-arch implementation of dump_stack(). (Where we might add new goodies in the future).
Problem is that this will add a new an pointless entry to all the stack dumps, unless the arch_dump_stack() implementation is smart enough to skip the innermost frame.
