- * A simple API for unwinding kernel stacks. This is used for
- * debugging and error reporting purposes. The kernel doesn't need
- * full-blown stack unwinding with all the bells and whitles, so there
- * is not much point in implementing the full IA-64 unwind API (though
- * it would of course be possible to implement the kernel API on top
- * of it).
