Johannes Weiner 28a0ce7f64 xtensa: use correct stack pointer for stack traces
Right now, the xtensa stacktrace code reads the _current_ kernel stack
pointer if nothing is supplied.  With debugging facilities like sysrq
this means that the backtrace of the sysrq-handler is printed instead
of a trace of the given task's stack.

When no stack pointer is specified in show_trace() and show_stack(),
use the stack pointer that comes with the handed in task descriptor to
make stack traces more useful.
