#6139: [PATCH] ppc: Implement arch_debug_get_caller

Comment(by andreasf):
Right, it would've returned the requesting function as caller.
As can be seen in [comment:ticket:6129:5 #6129], {{{stack_trace}}} itself
is included in the stack trace. This is remedied accordingly in patch 2.
Ideally I would like to see everything including {{{panic}}} vanish from
the regular stack trace, but that would seem to require major kernel
debugger API refactoring, pushing the callsite of
{{{debug_call_with_fault_handler}}} to arch-specific code to strip known-
preceding frames.[[BR]]
Inside ppc it might be feasible to split {{{stack_trace}}} in one function
with {{{stack_frame*}}} argument and a wrapper with the present {{{int
argc, char** argv}}} args to handle the {{{evaluate_debug_command}}} case.
