show_stack(current or NULL, NULL) is used by arch-independent code to dump backtrace of the current task; however, sparc32 show_stack() doesn't implement it and wouldn't print any backtrace when NULL @_ksp is specfied. Make show_stack() acquire and use %fp if @tsk is NULL or current and @_ksp is NULL. This makes %fp fetching in dump_stack() unnecessary. Make it use NULL for @_ksp instead. Only compile tested.
