	SRR0/SRR1 are he status save/restore registers.  The registers
receive the value of the PC and MSR at an exception and are used to
restore the PC and MSR when returning from an interrupt.

	Maybe "nip" means "next instruction pointer"?  Then nip/msr would
correspond to the SRR0/SRR1 for the state to be restored, but it sure
isn't standard PowerPC or NetBSD terminology.
