So, you mean that just repeating 
	setr13(PsrMfiq, m->sfiq);
	setr13(PsrMirq, m->sirq);
	setr13(PsrMabt, m->sabt);
	setr13(PsrMund, m->sund);
could do the job, since they always point to the same place.

I'll try that.
thanks a lot.

There is an r13 for each mode.  On traps, we always trampoline to svc
mode so that the r13 registers are always pointing to the same place
when we are interruptible.  You will definitely lose this state in
idle/sleep mode. I'll look at it a little more closely tonight.
