- * pcb_save - save process context, i.e. callee-saved registers. This
- * function is called by savectx() and cpu_switch().
- *
- * The callee-saved (ie preserved) registers are:
- *	r4-r7
- *	f2-f5, f16-f31
- *	p1-p5, p16-p63
- *	b1-b5
- *	ar.unat, ar.lc
- *
- * Notes:
- * o  We don't need to save and restore gp because its value is constant.
- * o  We don't need to save and restore ar.rsc because its value is known.
- * o  We don't need to save and restore r13 because it always points to
- *    the pcpu structure.
- *
- * Arguments:
- *	r8	'struct pcb *' of the process that needs its context saved.
- *	b6	return address.
